350 Mil. R. E. TURNER OX THE [Feb. 15, 



rounder] at the anterior angles, the second segment very large, a 

 little broader than the first ; the apical segments narrowing 

 rapidly ; the sixth segment small, narrowly triangular, pointed 

 and sparsely punctured, smooth and shining beneath. 



Opaque black ; the legs (except the coxa?), the tegula?, and the 

 apex of the scape ferruginous ; mandibles fuscous. Wings 

 hyaline, clouded with fuscous, nervures fuscous. 



Flagellum missing. The neuration is as in Kohl's figure of 

 iS. punctuosus, but the third cubital cell is much shorter on the 

 radial nervure, the third abscissa of the radius being little more 

 than half as long as the third transverse cubital nervure ; the 

 radial cell is rounded at the apex, not appendiculate. 



Length 10 mm. 



Hah. Claremont, W. A. (H. M. Giles). 



Very near punctuosus Kohl, which was described from a male, 

 and I should have hesitated to separate the present species but 

 for the marked difference in the shape of the third cubital cell, 

 which is not likely to be sexual.

d • Clypeus produced in the middle over the mandibles and 

 truncate at the apex, strongly transversely depressed at two- 

 thirds from the base, the depressed apical portion microscopically 

 punctured, the raised basal portion sparsely punctured and pro- 

 duced at the apical angles into very short carina? bordering the 

 depressed portion at the base. Eyes converging towards the 

 clypeus, separated on the vertex by a distance at least half as 

 great again as that separating them on the clypeus ; the posterior 

 ocelli as far from each other as from the eyes. Head rather 

 shallowly punctured-rugose, covered with short white pubescence, 

 close on the clypeus, sparse elsewhere ; a transverse carina on the 

 front, nearer to the base of the antenna? than to the anterior 

 ocellus, not reaching the eyes, slightly pointed in the middle and 

 produced into a strong longitudinal carina reaching to the base 

 of the clypeus. Antenna? gradually thickened to the apex, the 

 second joint of the flagellum the longest, a little longer than the 

 apical joint. Thorax coarsely punctured-rugose, the anterior 

 margin of the pronotum broadly arched, the anterior angles of 

 the propleura? with a minute spine. Scutellum and median 

 segment longitudinally striate-rugose ; the scutellum almost flat ; 

 the apical angles of the median segment produced into stout 

 spines, the surface of the posterior truncation longitudinally 

 striated at the base, then reticulate ; the sides of the segment 

 indistinctly obliquely striated. Abdomen ovate, broadly truncate 

 at the base, rather closely punctured, coarsely on the basal 

 segment, more finely on the second and third segments, the 

 punctures on the apical segments more or less confluent longi- 

 tudinally ; the apical dorsal segment much broader than long, 

 rather narrowly truncate at the apex. 



Opaque black ; the first dorsal segment of the abdomen dull
