and the outer margin seems to be entire; eyes strongly converging 

 towards the vertex, so that the distance between them at that point is 

 about equal to half of that at the mandibles; ocelli round, convex, 

 a /ill situated so as to form a rather high triangle; antenna' situated 

 very low down, the middle lobe of clypeus extending up between 

 them, rather long, very slightly thickened medially (the thickening 

 is more obvious in the S ) and narrowed to apex, alike in both sexes, 

 i. i . those of the £ are not formed into n spiral as in Dinetus; protho- 

 rax large and very prominent, not emarginate above, and the an- 

 terior portion is not cut off so suddenly as in most of the allied gen- 

 era ; when compared with the dorsulum it is fully two-thirds as long; 

 metathorax longer than the dorsulum, with no distinct enclosure; anter- 

 ior wings with an extremely short marginal cell, which is broadly 

 truncate at apex, and has a long and distinct appendiculate cell; 

 there are three cubital or submarginal cells, the first ot which is longer 

 than the two others combined, the second submarginal cell is trian- 

 gular; the first and second recurrent nervures are received by the 

 first and second submarginal cells respectively, as in Dinetus; an- 

 terior tarsi of 9 with a comb formed of long, slender, widely sepa- 

 rated spines; the $ has no tarsal comb ; middle tibia' of both sexes 

 with two spur*. Last dorsal segment of 9 with an elongate triangu- 

 lar pygidium.

9. — Middle lobe of clypeus convex, produced a little anteriorly, 

 the lateral lobes depressed; front and vertex polished, seemingly 

 impuuetate; antenna? long, setaceous, fiagellum with joints 1-4 

 about ecpual in length; vertex with a fovea on each side of ocelli; 

 dorsulum and scutellum polished, impunctate; scutellum convex, 

 not impressed ; upper surface of metathorax granulated, the meta- 

 pleurse coarsely striated; legs tolerably spinose; pygidial area 

 sparsely punctured, not prominent. Black; clypeus medially, man- 

 dibles except apex, antenna 3 , prothorax and four anterior legs, pale 

 brown, the hind legs and abdomen castaneous; tegula? and humeral 

 tubercles, yellowish; wings subhyaline, nervures testaceous. Length 

 6 mm. 



$ . — Similar to the 9 ; first joint of fiagellum a little longer than 

 the second; clypeus and sides of face bright yellow; prothorax and
