PHYTOPHAGOUS COLEOPTERA FROM BURMA 949 



transversely sulcate at the disc; elytra parallel with a few fine 

 punctures; legs slender; the first joint of the posterior tarsi as 

 long as the following two joints togetlier, tibiae unarmed, an- 

 terior coxal cavities open.

It is almost impossible to give a correct idea of the structure 

 of the antennae in the male, as every joint is of different shape 

 and size, in the female the eighth joint is the longest and sub- 

 cylindrical; C. monstrosa is allied to C. nodicornisj, Wied., but 

 is of course quite distinct. Several female specimens which ap- 

 parently belong to this species differ, in having more elongate 

 joints of the antennae, while in one specimen the abdomen is 

 flavous , otherwise I can see no difference , but it is possible 

 that these specimens represent closely allied species. 



110. Luperxis constrictieollis, n. sp. 



Blacli, shining, the legs more or less testaceous, the thorax 

 strongly narrowed at the base, impunctate ; elytra scarcely per- 

 ceptibly punctured, the base with a more or less distinct testa- 

 ceous spot. 



Length 1 V2 ^i^^®- 



Of slightly posteriorly widened shape, rather convex, the 

 head impunctate, transversely grooved between the eyes, the 

 frontal tubercles distinctly raised, the carina rather short and 

 broad, antennae stout, not extending to half the length of the 

 elytra, black, the lower three joints more or less piceous, the 

 second and third joints short, tKe latter one half longer than 

 the preceding one, the following joints longer and rather thick; 

 thorax slightly broader than long, the sides greatly narrowed 

 at the base, rounded and widened at the middle, the anterior 

 angles slightly oblique, forming a small tubercle furnished with 

 a single white seta, the surface rather convex, smooth, impunc- 

 tate, the extreme base with a slight transverse depression at 

 each side (only visible in a certain light) scutellum broadly 

 ovate ; elytra wider at the base than the thorax, scarcely more
