scutellura strongly punctured. Median segment short, rounded, 

 shining, with small shallow punctures. Abdomen petiolate, 

 smooth and shining, the second segment depressed at the base. 

 Hypopygium shorter than in most of the species of the genus, 

 with a lateral spine near the base, then gradually narrowed to the 

 base of the apical spine, which is slightly recurved. Black; the 

 mandibles dark rufo-testaceous-black at the apex; antennae, except 

 the basal half of the scape, the legs, except the coxae and tro- 

 chanters, the first, second and basal half of the third and the 

 whole of the two apical abdominal segments bright rufo- testaceous. 

 Wings pale flavo-hyaline, nervures testaceous, the stigma fuscous. 

 Length 12 mm.

(J. Smith's description does not refer to the sculpture. The 

 clypeus has a carina from the base not reaching the apex, 

 which is smooth, thinly clothed with long cinereous pubescence. 

 The head densely punctured. Prothorax very shallowl}', 

 mesothorax more strongly, median segment finely and densely 

 punctured. Abdomen shining, the hypopygium with a spine on 

 each side near the base, thence sharply narrowed into the apical 

 spine, which is long and slightly recurved. The six or seven 

 apical joints of the antennae are produced and narrowed beneath 

 at the base. The cubital nervure is bent at the point of recep- 

 tion of the first recurrent nervure, having beyond that point 

 almost the appearance of being a continuation of the first recurrent 

 rather than of the cubital nervure. The division of the first 

 cubital cell is indicated by a faint scar only. 



9. Head quadrate, much broader than the thorax, punctured, 

 the projection between the antennae divided by a median suture, 

 a small tubercle at the base of the mandibles, which are simple. 

 The anterior portion of the prothorax depressed, with a median 

 carina, and the lateral margins slightly raised, having a depres-
