Upper Side. Head black. Eyes yellow brown, round, and projecting from the head a little; between them are two small orange spots. AntennÆ small and short. Thorax black, with four orange spots in a row, placed across it, and behind them two others. Abdomen black, consisting of seven annuli or rings, besides the tail part, the last of which is edged with orange. Anus orange-coloured, and furnished with a bristle for oviposition. Wings black, spotted, and streaked with orange; the anterior having a row of streaks along the external edges, and five distinct orange spots crossing the middle, near the shoulders: the posterior having a large orange patch on the abdominal edges, and a small round spot above it, with five small fainter ones placed along the external edges.

Under Side. Head black, terminating in a long slender beak, which extends between the legs, to the abdomen; two small orange spots are placed just below the eyes. Thorax with an orange spot on each side. Legs and abdomen black; the latter having six orange spots, three on each side. Wings as on the upper side.

Head short, thick, and of a yellowish brown, with a black stripe down the middle. Eyes round, and projecting. Ocelli distinct. Thorax yellow brown. Abdomen nearly black. Anterior wings yellow brown next the body, but darker in the middle; the external edges being transparent; above which is a row of transparent spots, placed between the tendons of the wings.

Legs yellow brown; rostrum extending between them, to the middle of the abdomen.

The colours of this insect appear to have been faded. Head red brown, having on the top a small moveable horn, like a bristle, which the insect can raise at pleasure. Eyes dark. Thorax and abdomen dark brown. Anus white. The ends of the anterior wings are red brown; from whence, to the shoulders, they appear of a dead black, spotted with small white spots; but when the insect was living, probably the black part was of a fine mazarine blue. The external edges of the posterior wings are transparent; the abdominal edges white, and the middle part black, spotted with white, like the superior. Breast, beak, and legs, red brown. Abdomen, on the under side the same, being edged with scarlet.

Head and thorax red brown, and hairy. The former furnished with two jaws, and tongueless. Eyes and antennÆ black, the latter shorter than the thorax. Wings transparent; the anterior being cloudy at their extremities, and along the anterior edges. Abdomen, and hinder part of the thorax, black and hairy. All the legs full of bristles; the hinder ones having two long spines at the tarsi and tibial joints. One of the sexes is much larger than the other.

Head small and hairy, being concealed beneath the thorax. The upper part shines like silver. Mouth of a greyish colour, and furnished with four palpi, whereof two are long and the other two short and thick. Eyes not to be discerned. AntennÆ about half the length of the insect; small, and filiform, but full of joints. Thorax and abdomen dark lead-coloured, shining like polished metal; being furnished along their sides with short hairs. The former has a cream-coloured stripe crossing it from side to side; it is also margined. In some specimens, the middle part of the abdomen, from the thorax to the tail, is of a silvery white; but in others the last ring only is so. At the extremity of the abdomen are placed three tails, of equal lengths, like bristles, but very hairy. These tails are in length about one-third of the whole insect; and, when the creature is alive, are always carried in the position represented in the figure. The middle one seems immoveable, the others are not. All the under part of the insect appears of a shining, silvery, white colour; and near the extremity of the abdomen are placed four little horny filaments, two on a side. Legs silvery. Thighs and tibiÆ broad and thin.
