LAMIA (POLYRHAPHIS) CANCRIFORMIS.

Plate XXXV. fig. 1. (or the upper figure).

Order: Coleoptera. Section: Longicornes. Family: LamiidÆ.

Genus. Lamia, Fabr. Cerambyx, Linn. (Subgenus: Polyrhaphis, Serv.)

Lamia (Polyrhaphis) Cancriformis. Thorace multidentato; dorso plano, elytris pustulatis, tibiisque anticis unidentatis. (Long. Corp. fere 1 unc.)

Syn. Cerambyx cancriformis, Fabr. Sp. Ins. 1. 209. 4. Syst. Ent. 165. 4. Syst. Eleuth. 2. 289. 40. (Lamia c.)

Cerambyx pustulatus, Drury, App. vol. 2.

Habitat: Jamaica.

General colour grey brown. Head furnished with strong mandibles. AntennÆ (with the basal joint very thick) much longer than the insect. Thorax rough, gibbous, and full of small pustules, two of which form an obtuse spine on the sides. Scutellum small and triangular. Elytra margined, and full of small pustules, having two spines fixed at their extremity, near the suture. Fore-legs long. TibiÆ with a single spur. Femora clavate.

LAMIA (MONOCHAMUS) DENTATOR?

Plate XXXV. fig. 2. (or the left-hand figure).

Order: Coleoptera. Section: Longicornes. Family: LamiidÆ.

Genus. Lamia, Fabr. Cerambyx, Linn. &c. (Subgenus: Monochamus, Meg.)

Lamia (Monochamus) Dentator. Thorace spinoso, fusco cinereoque varia. (Long. Corp. 1 unc. 1½ lin.)

Syn. Lamia dentator, Fabr. Syst. El. 2. p. 294. 70. Haworth in Ent. Trans. 1. t. 1?

Cerambyx carolinensis, Oliv. Ent. 4. 67. p. 85. t. 12. f. 88.?

Cerambyx notatus, Drury, App. vol. 2.

Habitat: See Observation below.

Head grey brown. AntennÆ grey brown, and about the length of the insect. Palpi four, and just above the mouth are placed, on each side the head, two protuberances. Thorax grey brown, dappled with black; having on each side a short thick spine. Scutellum small and triangular. Elytra grey brown, dappled with small black streaks, and extending beyond the anus. Abdomen, breast and legs grey brown, like the rest of the insect.

The insect figured by Drury is stated to have been received from Norway. No Longicorn beetle, corresponding with Drury's insect has been ascertained to be a native of that country, or indeed of Europe. Hence, as this figure very nearly corresponds with the American Lamia dentator of Fabricius, I am inclined to believe that Drury's specimen had been imported from North America, in the same manner as the specimen described and figured by Mr. Haworth in the Transactions of the former Entomological Society, and which was taken near London. I have, however, marked the synonyms with doubt, this figure having been overlooked by all subsequent authors.

ELATER AURATUS.

Plate XXXV. fig. 3.

Order: Coleoptera. Section: Serricornes. Family: ElateridÆ, Leach.

Genus. Elater, Linn. &c.

Elater Auratus. Cyaneo aut viridi-nitidus subtus cupreus, elytris acuminatis. (Long. Corp. 1 unc. 9 lin.)

Syn. Elater auratus, Drury, App. vol. 2. (1773). Linn. Syst. Nat. (Gmel.) 1. iv. 19. 14.

Elater fulgens, Fabr. Ent. Syst. 1. 11. p. 220. 22. 17. (1792.) Syst. Eleuth. II. 226. Oliv. Ent. 2. 31. 12. t. 4. f. 43. Herbst. Col. ix. p. 343. t. 158. f. 12.

Habitat: China.

Head green. AntennÆ black, and shorter than the thorax; having at each joint some short hairs. Thorax green, and margined, appearing as if finely polished; the hinder corners being pointed, and forming obtuse angles. Scutellum round and shining. Elytra likewise green, shining, and margined; their extremities terminating in two sharp points. Under side shining green, except the tarsi, which are black.

This beautiful insect may be regarded as the most brilliant species belonging to the family, ElateridÆ, the majority of which are of dull and uniform colours, thus affording a strong contrast to the splendid family of BuprestidÆ, to which they are very nearly allied. The family ElateridÆ are all, as Drury observes, provided with an instrument which extends along the breast, about the thickness of the thighs, to the abdomen, where the end of it is received into a groove, forming a spring, by which the creature, when laid on its back, can jump to a considerable height, from which circumstance it has received the name of Elater.

LAMIA (ACANTHODERES) ARANEIFORMIS.

Plate XXXV. fig. 4. (or the bottom figure).

Order: Coleoptera. Section: Longicornes. Family: LamiidÆ.

Genus. Lamia, Fabr. Cerambyx p. Linn. (Subgenus: Acanthoderes, Serv.)

Lamia (Acanthoderes) Araneiformis. Thorace spinoso tuberculatoque elytris porosis, macul marginali fuscÂ, antennis longis. (Long. Corp. fere 1 unc.)

Syn. Cerambyx araneiformis, Linn. Syst. Nat. 1. 2. 625. Oliv. Ent. 4. 67. 64. t. 5. f. 34. Fabricius Syst. Eleuth. 2. 288. 37. (Lamia a.) Sloane Hist. Jamaica, 2. 209. 19. 2. t. 237. f. 24. Serville Ann. Soc. Ent. Fr. 1835. 30. (Acanthoderes a.)

Habitat: Antigua (Drury). "In America Meridionali" (Fabr.).

Head dark brown. AntennÆ longer than the insect; the sixth joint being furnished with a small tuft of hairs. Thorax brown, very rough and uneven, occasioned by the many bumps or swellings on it; two of which, like thick spines, are situated on the sides. Scutellum small. Elytra brown, and full of small pustules. In the middle are two oblong black streaks, placed next the suture. Legs brown, femora very thick. Tarsi yellow underneath, and pilose; those of the fore-legs being very hairy.
