Natural Order.—CERAMBYCITES, Newman.

Genus.—CALLISPHYRIS, Newman.

CAPUT pronum, prothorace angustius; antennæ dimidio corporis vix longiores, 11-articulatæ, simplices, apice paullò crassiores: prothorax lateribus medio dentatis: elytra dimidio corporis manifestò breviora, a basi ad medium pedetentìm angustata, ponè medium linearia: pro- et mesopedes breves, simplices, femoribus haùd tumescentibus; metapedes elongati, femoribus tibiisque valdè hirsutis.

Inhabits South America. A single specimen, taken by Mr. Darwin on the Island of Chilöe, is in the cabinet of the Entomological Society of London.

This fine insect in some of its characters closely resembles Odontocera, of Serville, but the structure of its antennæ, the tooth on each side of its prothorax, and its slender and simple pro- and meso-femora, incline me to consider the similarity merely dependant on its rowed elytra and hirsute metatibiæ, and not implying any very near approach to that well-known genus.

Cyll. spinifera. Fusea, obseura, lanuginosa: prothorax maculis duabus glabris ornatus: antennarum articuli basi cinerei: elytra fusca, maculis fasciisve lanuginosis cinereis ornata. (Corp. long. 7 unc. lat. 225 unc.)

Inhabits South America. Specimens taken by Mr. Darwin are in the cabinet of the Entomological Society. I find no description of this insect in Serville's 'Nouvelle Classification,' but it is by no means uncommon in collections: it bears as close a resemblance to Clytus as Phacodes to Callidium.

The descriptions which follow have no reference to any particular family of Longicorns, but are simply recorded as supposed novelties to the science.

Inhabits Demerara. Three specimens of this lovely insect were taken by M. Schomburgk, who kindly allowed me to describe and name the species. The entire colour is pitehy black, with the exception of three large spots on each elytron of a beautiful straw colour: of these spots the first is humeral, transverse, and extends from the costal margin to the scutellum, but does not quite reach the base; the second is median, transverse, and reaches the costal but not quite the sutural margin; the third is nearly apical, almost round, and does not reach either of the margins; the prothorax is rugose, and has five dorsal protuberances arranged thus, ; the scutellum is elongate, linear, narrow, and has a longitudinal impression, it is of a clear pitchy black. This description was read before the Entomological Society of London, in 1839.

[page] 12

Inhabits South America. In the cabinet of the Entomological, Society of London; taken by Mr. Darwin at Valparaiso. This little longicorn, which a good deal resembles a small brown spider, is very closely allied to the genera Compsosoma and Ensphærium, but appears to me sufficiently distinct from both.

Inhabits South America. A specimen in the cabinet of the Entomological Society of London, was taken by Mr. Darwin at Bahia. It differs but slightly from Megacera macrocera of Serville, except in size, being scarcely more than a seventh part as large; the little projections on which the antennæ are situated are less prominent than in that species, and the extremities of the elytra less pointed and less divaricating.

Genus.—SAPERDA, Fabricius.

Inhabits Mexico. In the cabinet of the Entomological Club. This and the preceding species are very similar, but on comparison appear distinct: the present is the larger insect; its hue is rather ash-colored than grey, and it wants the delicate sutural line of the elytra.
