Longicornia Malay ana. 643 



included in it, the two being, as I think, congeneric. C. 

 metJwcoides,^ has a more ovate prothorax {i. e. rounded 

 at the sides and broader than the head), the elytra much 

 shorter, chesnut-brown at the base, with a reflexed longi- 

 tudinally compressed spine or tubercle near the shoulder; 

 the elytra also are somewhat enlarged or inflated pos- 

 teriorly. The genus seems to me to be a very doubtful 

 member of the Ceramhycidce.

Hab. — Singapore. 



Pitchy-black, smooth and shining; head as broad as 

 the prothorax, the latter gradually narrower posteriorly 

 to the constriction, not rounded at the sides, which are 

 anteriorly in a line with the head; scutellum minute; 

 elytra nearly parallel, broadly constricted near the middle, 

 the apex of each with a little tuft of white hairs; an- 

 tennae and legs with a reddish-tinge, especially the 

 clavate portion of the femora.

Two Malayan genera, only one of which, however, is 

 represented in Mr. Wallace's collection, and each com- 

 prising a single species, constitute this subfamily. Its 

 special character lies in the form of the head, which 

 is large compared to the prothorax, and is abruptly 

 contracted behind; the eyes are large and prominent, 

 and deeply emarginate ; the prothorax is very long, and 

 the body slender. The sexes are unknown, as only one 

 individual of each of the two species has been hitherto 

 detected. 



* M. Lacordaire, partially misled probably by the phrase "head parallel 

 with the thorax," intended to apply to the side, not totlie upper part, ha3 

 assumed that the head is not perpendicular, and on that account, in con- 

 jimction with the different form of the elytra, is inclined to consider 

 C. WestivoocUi as j^eueiically distinct.
