Amidst the many sounds of the restless Indian night, some far away, some near at hand, there is one which, when it commences, drowns all the rest. It is a harsh, metallic, rasping, shrill, unmusical sound. It might seem as if it had to do with some machinery, except that it is unlike the sound of any machine that you ever heard. It begins in the room where you are sitting reading, or else out in the verandah, where you are enjoying the cooler breeze of evening. Loud as it is, you cannot locate it. At one moment you think it is up aloft amongst the rafters, at another moment it seems to be close by. It emanates from an uninteresting-looking brown insect, about an inch long, who makes prodigious jumps like a grasshopper. One night when this din was so great that conversation was almost impossible, I was astonished to find that the insect was on the table, only a few inches away from my book, and I was able to see his method of making this sound. He was vibrating his horny wing-cases with marvellous rapidity, producing such an amount of noise that, unless one had seen it in process of production, it would have seemed impossible that it could arise from such a humble source.

At certain seasons, and especially when it is warm and damp, the evening meal in the country is attended with difficulty because of the quantity of insects, especially beetles, which are attracted by the lamp, and they appear to make a specialty of falling into any dish which may be at hand. When camping out the difficulty is intensified, and the only thing to be done is to put the lamp at a distance and to dine in comparative darkness. Such a variety of insects come that an entomologist might make quite a respectable collection in the course of one night. One of these evening visitors after the rains is a long, slim beetle, green, or sometimes buff in colour, with a small head which fits loosely into his body. He twists his head about as if his collar was uncomfortable. When alarmed he exudes a strong acid which at once raises a blister. He is the more dangerous because, flying in rapidly, he often alights on your collar or neck, and the action of brushing him off causes the emission of the acid, and the blister follows.

In the daytime, bees, black and hairy, immense in size, and making a noise like a threshing-machine, come banging in at the open windows. They are not as formidable as they look, except in their own domains, and they quickly depart in response to indications that they are not wanted. They know their way out without difficulty, which is contrary to the experience of most intruding animals.

A solitary wasp is apt to select inconvenient places in which to build a mud-cell wherein to deposit its egg, and the store of live caterpillars destined to be the food of its young when hatched. You find a keyhole, or the tap of a filter, filled with mud as the result of this wasp's labours. It works so rapidly that it generally completes its job in the course of a day. An even more inconvenient site for its nest is the sleeve of a garment left hanging on a peg, especially if you put the garment on while the wasp is at work. A small colony of social wasps built their comb under the refectory table of the village Mission-house. They were so determined to remain that for some months they resisted all attempts to get rid of them, returning as often as they were dispersed.

Cockroaches, some of great size, abound in most houses, and are very destructive. They nibble the bindings of books, and cut quaint devices, which look almost as if they had been done with a pair of scissors, in clothes put away in drawers. They run at an amazing pace when they think they are in danger.

Jet black ants, enormously big and warlike in appearance, come into bungalows, sometimes in unpleasantly large numbers, to see what they can pick up. They are not really aggressive, nor do they do any particular mischief. Another kind of ant, very like an ordinary English one though smaller, is a great trial to housekeepers. They get into the bread and sugar and other stores, and though cupboards are generally set in saucers of water on account of insect depredators, these ants often manage to get in.

White ants are most destructive in a house if it is built of materials which they can deal with. In the case of many houses in India, mud is used instead of mortar, and the structure suffers greatly if the white ants take possession. All woodwork, including furniture, ought to be of teak, because they are unable to burrow into it. Sound hard floors are necessary, so that when ants try to work their way upwards they may find their road blocked. Otherwise, in the course of one night, they will eat large holes in a mat or carpet, coming up from beneath. They make havoc in a library if they get amongst the books. Many ant-heaps out in the country are so large as to be conspicuous objects.

Scorpions may be found anywhere. In your bedding, in your boots, in your clothes, under your books and, out of doors, chiefly under stones. You soon get into the way of prudently shaking each garment before putting it on. The scorpion averages about two inches in length, but they vary a good deal in size, and also in colour. They much resemble a little lobster in appearance. Their sting is not dangerous under ordinary circumstances, but the pain is great, and resembles a blow on the funny bone, continuing acute for some hours. The boys, sleeping on the floor and having bare feet, get stung now and then, and generally make great lamentations over the misfortune.

Indian boys are like many English rustics in their disregard for the feelings of animals—they appear honestly to think that they have none—and they delight in forming a chain of scorpions by making them grip each other, which they do fiercely, and hang on tenaciously. Boys will also nip off the end of their tail to prevent them from stinging, and leave them in this maimed condition.

Wherever Indians live, bugs are invariably found. Hence in schools where many Indian children are gathered together these insects are sure to find an entrance, in spite of vigilant care and cleanliness. When the small boys of the Mission moved out from their old quarters in the city, which like all old native houses was much infested, immense pains were taken to make sure that no bug was transported to the new home in the country. But it was not long before these intruders showed themselves in the new house. Possibly they fulfil some useful but at present unknown function as destroyers of microbes.

Spiders are much in evidence, and some are very large and fierce. Out in the country I once fairly ran away from a great spider, which made for my foot with a courage and ferocity such as one would not expect to find in an animal of the kind. But they are not altogether unwelcome in a house, because they help to keep down the population of the insect world. There is a handsome little spider who spins no web, and roves about, and springs on its victim like a tiger.

Mosquitoes are the most troublesome insects to be found in the tropics, although some districts are much more infested than others. There are several different kinds. The one that causes the most irritation is smaller than the average English gnat. They are veritable bloodsuckers, and the amount of blood which a mosquito can imbibe is astonishing. They may be seen so distended after their night's work that they can scarcely fly. Newcomers from England are their special prey, and their bites often cause a good deal of inflammation. The loud hum with which they approach is almost as disturbing as their bite. Most English people have nets of fine gauze surrounding their beds, and some Indians have adopted the same precaution since the promulgation of the theory that the bite of an infected mosquito is the cause of malarial fever. Natives when they sleep, generally roll themselves up completely, head and all, in a dhota, which they use then after the manner of a sheet. The mosquito-nets cut off a good deal of air, and people are tempted to discard them unwisely when the nights are intensely hot. The framework from which the nets depend is a frail counterpart of the four-poster of the Victorian age. The net is usually tucked in under the mattress, to prevent any possibility of the mosquito entering. In places where mosquitoes abound they are troublesome by day as well as by night, and they are specially fond of attacking the ankles of persons seated at table.

Towards the close of the rainy season flies become numerous almost everywhere, but especially in a native city like Poona, and they are an unpleasant indication of its unsavoury condition. They fall into your cup, the table is black with them, your food becomes a matter of dispute between you and them. But out of doors, except at meal-time in camp, they are not nearly so aggressive as the summer flies which buzz around during a country walk in England. Though they could be dispensed with without regret, they are probably of great value as scavengers.

There is a very small fly which is popularly known as the "eye-fly," because it hovers in front of your eye like a troublesome person who will not take a refusal. It apparently thinks that the pupil is the entrance into some desirable chamber. Fortunately it rarely gets beyond the stage of prospecting this supposed entrance. Now and then it travels round to your ear and prospects there also. But though it does so at a safe distance it makes an irritating hum, and it is so small that attempts to flap it away are futile.

There are many striking instances in India of insects being protected from their enemies by their likeness in colour and markings to the tree or plant on which they feed. The most noteworthy example of this is a long insect, so precisely similar to a bit of dry stick that, until you actually see it walk, you can hardly believe that it can be anything else.

Butterflies, in the Poona district at any rate, are disappointing. They are larger than the English ones—the scale of most things in India is big—but their colours are not strikingly brilliant. Some of the large moths are handsome, but not more so than many of the English nocturnal moths.

The most comical insect is the praying mantis. It is of a fresh green colour, often three or four inches long, and something like a grasshopper in appearance. When it alights on your table in the evening, attracted by the lamp, it behaves in a seemingly ridiculous way. It puts its long front legs together as if praying, and sways about as it does so in an absurdly affected fashion, reminiscent of Thackeray's description of Charles Honeyman in the pulpit.
