2 TETUALANOURIA. 



Pachylanguria metasternalis, sp. n, 



Oblouga, crassa, piinctulata, cyaneo violacea, tliorace lateribiis 

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

 (Bake well). 



Body beneath rather obsoletely punctate, sides of mesoster- 

 num with a few very deep punctures; prosternum with the pro 

 cess deeply sulcate on each side, apex triangularly emarginate. 



Tetralangmia. 



g. n. {typ. splendens, Wied,). 



Closely resembling PachijIangiiTia, but v/ith the thorax elongate 

 and with anterior angles well maiked, the posterior produced, 

 acute. 



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

 at present prepared to diffei'entiate them. Probably most of those 

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



Tetralangnria elongata, 



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



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

 Singapore, and of which I have seen numerous examples agreeing 

 with the Fabrician description.
