Genera and Species of Coleoptera. 129 



J Elytris convexis, angulis posticis comutis. 



$ Elytris deplanatis, angulis posticis muticis. 



Ovate, dark pitchy-brown, sparingly furnished above with pale yellow- 

 ish-green scales; rostrum longer than the head, gibbous below the 

 eyes, and separated from them by a semicircular depression, with a 

 broad longitudinal furrow in the middle ; prothorax shortly ovate, 

 closely granulated, and covered with coarse deep punctures ; scutellum 

 none ; elytra very short, perpendicularly bent down behind, roughly 

 punctato-granulated, slightly convex in the male, with the posterior 

 angle produced into a long flexible process, flat and depressed in the 

 female, and without any prolongation ; legs moderate, furnished with 

 stiff scattered hairs, the femora orange-red, except at the apex (in the 

 female darker) ; antenna? black, shorter than the body, slightly hairy : 

 body beneath pitchy, coarsely punctured. Length 3A lines (cf), 

 3 1ines($). 



Blapsilon [Cerambycidae]. 

 Head short, scarcely convex in front. Eyes small, lateral, deeply emargi- 

 nate. Antennas shorter than the body, sublinear, distant at the base, 

 the first joint thickened, shorter than the third, which is longest, the 

 fourth moderate, the remainder very short and subequal. Labruni small, 

 slightly emarginate. Mandibles robust. Palpi stout, the terminal joint 

 elongate-ovate, truncate. Mentum very short and transverse. Pro- 

 thorax broader than long, narrower in front. Scutellum elongate, pro- 

 duced anteriorly. Elytra ovate, broader than the prothorax at the base, 

 elevated in the middle, and produced at the shoulder into a short, hooked, 

 horizontal process. Legs moderate ; coxae distant ; tarsi short, very 

 slightly dilated. Prostemum received into a notch of the mesostemum. 



The scutellum of this genus is remarkable. It is not only un- 

 usually narrow and somewhat hexagonal in form, but it is projected 

 forwards on the prothorax, which is probably notched for its recep- 

 tion, although this point cannot be ascertained without risk of in- 

 jury to the specimen. Blapsilon must be placed near Tmesisternus. 



Blapsilon irroratum. (PI. V. fig. 8.) 

 B. fusco-piceum, maculis hirtis ochraceis punctisque impressis adspersis. 

 Hah. New Caledonia. 



Broadly ovate, dark pitchy-brown, the whole upper surface, except 

 the scutellum, covered with small, round, hairy ochraceous spots and 

 deeply impressed closely-set punctures ; body beneath pitchy-brown ; 

 anterior tibia? and tarsi paler. Length 7 lines. 

 There are two specimens in the British Museum, collected during 

 the surveying expedition of H.M.S. Herald. 



Atjxa [Lamiidse]. 

 Head small, convex in front, the vertex elevated. Antennae setaceous, 

 longer than the body, pedunculate, the first joint thickened, pyriform,
