collection of LcuKjuriidce from Assam. 25 



acuminate behind; elytra broader at base, with rows of strong 

 punctures, very strongly transversely rugose, interstices with single 

 rows of small punctures, margins continued very plainly along 

 shoulders to scutellum, apices subtruncate, with the exterior ex- 

 tremities bluntly elevated ; legs long, tarsi strongly dilated. 



Male much smaller ; head broad, antennae slender, with three- 

 jointed club ; thorax subquadrate, unicolorous, slightly longer than 

 broad, with no central furrow, but with plain short longitudinal 

 stria; at base. 



Assam. 



I am rather doubtful regarding this species, as the 

 male is so much smaller than the female that I should 

 hardly have united them, had it not been for the smaller 

 female referred to above, which, apart from its imma- 

 turity, appears to be structurally identical with the 

 larger one. 



In a paper on the group (Trans. Ent. Soc, 1885, 

 Part iii., p. 886) I have named a species Languria 

 femoralis ; I find, however, that this name has been 

 preoccupied by Motschulsky for a North American spe- 

 cies. I therefore propose to alter my name to L. nigro- 

 cenea. In the same paper (p. 382) I have said that in 

 Goniolanguria the clypeus has a strong V-shaped 

 emargination ; this is very plain in some specimens, 

 but I have since found that it is not constant in all ; 

 I believe that it is sexual, and is found in the female 

 only. 



Smce writing the above, I find that Von Harold {I. c, 

 p. 81) considers L. scutcllata, Crotch, as identical with 

 L. nigrina, Wied. I had arrived at this conclusion from 

 an examination of Mr. Crotch's specimens at Cambridge.
