Pronotnni not large; autennpe simple, neither compressed nor broad.

 short ; antennfe long, the flagellum snbclavate, clothed 

 with a short, dense pubescence. 



(36) Sphoeropisthus Thomson. 

 Head, seen from in front, not longer than wide ; marginal vein very short, 

 the postmarginal vein longer than the stigmal; flagelhim 

 filiform, the joints nearly' thrice as long as thick. 



(37) Chestomorpha Ashmead, new genus. 



35. Head not or less distinctly lenticular, opaque, minutely, closely punctate, sha- 



greened, or smooth and shining, at the most with only a 



few large punctures 39 



Head transversely broad, always lenticular, the scrobes short, the punctures 



large, thimble-like; hind wings with the costal cell usually 



extending to the booklets. 



Marginal vein larely short, at least longer than thick, and usually much 



longer; mesonotum smooth, impunctate, or at most sha- 



greened 37 



Marginal vein very short, punctiform, not or scarcelj^ longer than thick ; 

 mesonotum punctate. 

 Mesonotum with the punctuation unlike that of the head, the punctures 

 less dense and the surface finely coriaceous; postmarginal 



and stigmal veins short, subequal 36 



Mesonotum with the ijunctuation similar to that of the head; postmar- 

 ginal vein very short or subobsolete (rarely long), the 

 stigmal vein long. 

 Scape normal, without a leaf-like expansion beneath. 

 Punctures on head and thorax coarse and dense. 



Mesonotum very short, only about half the length of the 

 scutellum; postmarginal vein usually as long as the 

 stigmal; flagellum long, with long sparse hairs, not ar- 

 ranged in half whorls (39) Chalcaspis Howard. 



Mesonotum at leastas long as the scutellum or very nearly; 

 postmarginal vein much shorter than the stigmal; fla- 

 gellum with fuuicle joints subexcised at apex, with half 



whorls of long hairs (40) Boihriotkorax Ratzeburg. 



Punctures on head and thorax smaller and less dense; mesono- 

 tum a little longer than the scutellum. 



(41) Arattis Howard. 



36. Vertex and face broad, finely shagreened, and sparsely punctate; scrobes deep 



semicirculai". 

 Pedicel obcoiiical, longer than thick at apex, the flagellum subclavate, the 

 joints, after the first, wider than long. 



(42) Pentelicns Howard. 

 Pedicel very minute, the flagellu'u filiform, pilose, the joints subequal, 

 abovit two and one-half times as long as thick. 



(43) Blepyrus Howard. 

 Vertex and face very narrow, or not broad. 



Head with coarse thimble-like punctures, the thorax smooth, impunctate; 

 flagellum short, thick, filiform, clothed witli a dense 

 short pubescence, the joints wider than long. 



(38) Aenasius Walker. 

 Head smooth without coarse thimble-like punctures, at the most with some 

 sparse punctures on the vertex; flagellum long, sub- 

 clavate, not thick and only sjiarsely pubescent. 



(45) Euryrhopalus Howard.
