■carinato, 5 angusto, medio quadratim tuberciilato, 6 medio incon- 

 spictio, 7 magno, rhomboidali, medio obsolete depresso, latere 

 asymetrico et emarginato. 



Femina. Segmento ultimo transversim triangulari, brunneo. 



Long. 1-10 mm. 



This species comes close to caviventris, Eaffr., but differs on 

 ■account of the discoidal impression of the prothorax which is a 

 very faint one, whilst it is strong in caviventris ; it is also smaller, 

 has a shorter head and less conspicuous club to the antennas.
