878 (2) Mr. G. R. Crotch's Revision of 



Pachylanguria metasternalis, sp. n. 



Oblonga, crassa, punctulata, cyaneo violacea, thoi'ace lateribus 

 late, inetasterno macula lateral!, aurantiacis. L. 8j lin. India 

 (Bakewell). 



Body beneath, rather obsoletely punctate, sides of mesoster- 

 num with a few very deep punctvu-es; prosternum with the pro- 

 cess deeply sulcate on each side, apex triangularly emarginate. 



Tetralanguria. 



g. n. (t9/2). splendens, Wied.). 



Closely resembling Pachylanguria, but with the thorax elongate 

 and with anterior angles well marked, the posterior produced, 

 acute. 



The species of this genus are extremely variable, and I am not 

 at present prepared to differentiate them. Probably most of those 

 here given will ultimately prove to be varieties of one species. 



Tetralanguria elongata. 



Trogosita elongata, Fab., Syst. El. i. 152 (1801). 



This I believe to be a species very common at Penang and 

 Singapore, and of which I have seen numerous examples agreeing 

 with the Pabrician description.
