the base. The second recurrent nervure is received just before 

 one-quarter from the base of the third cubital cell. 



Black with sparse grey pubescence ; the apical abdominal seg- 

 ment ferruginous red. Wings hyaline, nervures black. 



Length 13 mm. 



2 . Clypeus without a carina, transverse. Head subrect- 

 angular, slightly rounded at the posterior angles, more than half 

 as broad again as long, sparsely but coarsely punctured. Pro- 

 notum sparsely punctured, with a row of large setigerous punc- 

 tures on the anterior margin, nearly twice as broad anteriorly as 

 long, slightly narrowed posteriorly. Scutellum very sparsely, 

 median segment more closely punctured, as long as the scutellum, 

 broadened from the base and obliquely truncate posteriorly, the 

 surface of the truncation very minutely and closely punctured. 

 First abdominal segment closely punctured, smooth at the extreme 

 apex and with the apical margin slightly raised, with a shallow 

 groove before it ; second segment with about eight irregular 

 transverse carina?, lowest at the base, including the raised apical 

 margin, which is further from the other carinas than they are from 

 each other ; third and fourth segments smooth at the base and 

 apex, punctured in the middle ; fifth dorsal segment smooth at 

 the base, sparsely punctured in the middle, with a few delicate 

 curved stria? at the apex ; fifth ventral segment coarsely longi- 

 tudinally striated. Pygidium not very narrow at the base, 

 obliquely sloped posteriorly and slightly broadened, with three 

 A-shaped carina? at the base of the slope, the apex of the dorsal 

 plate strongly trilobed, the ventral plate extending much beyond 

 the dorsal, rounded at the apex, with a very feeble emargination 

 in the middle. 



Black ; the two apical segments ferruginous red. 



Length 10 mm.

2 . Clypeus without a carina. Head more than half as broad 

 again anteriorly as long, strongly rounded at the posterior angles, 

 strongly but not very closely punctured, with a short and almost 

 obsolete longitudinal frontal sulcus. Pronotum almost rect- 

 angular, about one-quarter broader than long, finely, but not very 

 closely punctured, with a few scattered grey hairs, longest on the
