infumatis ; clypeo fere piano, apice late emarginato, angulis subporrecto ; 

 genis clente arraatis ; mesopleuris minute bituberculatis ; segmento 

 mediano area basali Itevi, opaca ; segmento ventrali secundo area basali 

 elevata nulla. 



Long. 9 mm. 



$ . Clypeus broader than long, widely emarginate at the apex ; the 

 emargination near the angles furnished with a slightly porrect oblique 

 carina on each side. Antennae inserted about half as far again from the 

 anterior ocellus as from the base of the clypeus ; the second joint of the 

 flagellum about half as long again as the third. Eyes slightly divergent 

 towards the clypeus ; the posterior ocelli nearly half as far again from the 

 eyes as from each other. Cheeks about as broad as the eyes, armed with 

 a short tooth. Pronotmn deeply depressed in the middle, rounded at the 

 angles ; mesopleurse with two minute tubercles. First abdominal segment 

 twice as broad as long ; second ventral segment without a raised area at 

 the base ; pygidial area broadly rounded at the apes, more than half as 

 broad again at the base as at the apex, gradually narrowed, about twice 

 as long as the greatest breadth. Closely and rather finally punctured ; the 

 enclosed area at the base of the median segment smooth but opaque ; 

 mesopleurse deeply punctured. 



Habitat — Chapra, Bihar (Mackenzie). 



In the Pusa Collection. 



The colour of the only specimen I have seen is reddish, evidently due to 

 discolouration by cyanide ; the colour in life is probably yellow or ochreous. 

 The spine on the cheeks is smaller than in the other two Indian species of 

 the group.

cJ . Clypeus as long as the greatest breadth, broad rounded at the 

 apex. Antennee inserted almost as far from the base of the clypeus as 

 from the anterior ocellus ; the second joint of the flagellum about one 

 quarter longer than the third ; the apical joint eqvial in length to the 

 penultimate, and very slightly curved. Eyes slightly divergent towards 

 the clypeus ; posterior ocelli more than half as far again from the eyes as
