fairly stout. Wings not reaching tip of abdomen, for the most 

 part hyaline but clouded somewhat beneath the stigma, which 

 is broad and short; radial cell also short, no longer than the 

 stigma, cubital cells complete, recurrent nervine entering 2nd 

 cubital cell, 1st discoidal cell short petiolate, nervellus almost 

 interstitial, subdiscoidal nervure entering discoidal shortly be- 

 low the middle, radius in hind wings obliterated.

Ascogaster argentea, n. sp. 



$ 5 mms. long. Black and shining, clothed with silvery 

 hairs, the antennae basally, fore and middle legs, trophi and 

 tegulae brown to fuscous, head, pro- and mesothorax finely to 

 coarsely punctate and areolate, metathorax and abdomen rugose, 

 the latter longitudinally striate basally. Head large, trans- 

 verse, wide between the eyes and thick, ocelli arranged in an 

 isosceles triangle on the vertex, the anterior angle obtuse, 

 lateral members as far from each other as from the occipital 

 margin, one-half the distance to the border of the eye, front 

 excavated behind the antennae, which are filiform, nearly as 

 long as the body, 1st segment stout, face short carinate above, 

 cheeks moderate, the postgenae bulging and much wider, 

 occiput concave and distinctly margined. Pronotum narrow, 

 the pleurae well developed, the mesonotum flat, the parapsidal 

 grooves represented by broad f oveate lines which widen posteri- 

 orly and merge at the posterior margin, pleurae convex, the 

 posterior margin with a deep costate furrow in front of it, 

 disc of the scutellum triangulate with a broad costate groove 

 in front, the lateral areas and postscutellum also costate, the 

 metanotum truncate posteriorly and areolate, the upper hind 

 angles denticulate, the two within less distinct. Abdomen as 

 long as the thorax, sessile, long oval, corbiculate, two lateral 

 longitudinal carinae at base, the venter deeply concave for 

 most of its length. Legs fairly stout, the metatarsus as long 

 as all the other tarsal segments together. Wings not reaching 

 tip of body, hyaline, stigma lanceolate, radial cell short, cubital 

 cells complete, 1st discoidal cell shortly petiolate, recurrent 

 nervure interstitial, nervellus postfurcal, subdiscoidal nervure 

 entering below the middle of the discoidal, radius in hind 

 wing obliterated.

Beognatha gracilis, n. sp. 



2 3.5 mms. long. Smooth or finely punctate and hairy, 

 the metanotum and 1st and 2nd abdominal tergites rugulose, 

 the latter microscopically sculptured, vertex on head, discs of
