Tetrathallis. 



g. n. {typ. carminea, Crotch). 



Differs from Thcdlis by the 8th joint of the antennae decidedly 

 dilated, and the prosternal process dilated beyond the coxse, finely 

 margined and deeply foveolate in the middle. The coxal lines are 

 both present, the mesosternum is smooth, oval in front, margined, 

 depressed in the middle, antennae with the 3rd joint a little longer 

 than the 4th. 



Tetrathallis carminea, sp. n. 



Oblonga, nigra, convexa, nitida, capite, thorace antice, corpore- 

 que subtus obscure rufis; elytris singulis maculis 2 (1 humerali 

 subobliqua, 1 subapicali) carmineis ; capite parcius punctato ; 

 thorace sat crebre punctato, subtransverso, angulis anticis deflexis 

 incrassatis, base tenuissime marginato, in medio leviter producto;
