widening slightly apically, together about as long as 1st, the 

 suture a little behind the middle, longitudinally striate to an 

 impressed line about one-third the length of 3rd segment from 

 posterior margin, beyond this the tergites. including 4-8, 

 smooth and shining and more or less compressed laterally, 

 with a transverse fascia of hairs at about the middle, the 

 stern ite of the 7th segment plowshareshaped, ovipositor as 

 long as body, the valves hairy. Legs long, slender, hind coxae 

 very large and stout. Wings reaching beyond tip of abdomen, 

 subhy aline, with a brownish yellow suffusion, stigma and ner- 

 vures dark brown, stigma lanceolate, radial cell short and 

 narrow, areola triangular, cubitus obliterated between 1st 

 cubital and 1st discoidal and beyond areola, a stump of a vein 

 proceeds from 2nd cubital cross-vein, subdiscoidal nervure and 

 the anal nervure apically as well as radius in hind wing 

 obliterated.

$ 5 mms. long. Black, shining, punctate and hairy, ab- 

 domen impunctate, polished, front and middle legs except 

 coxae, and trophi yellowish brown. 



Head transverse, wide between the eyes, triangular when 

 viewed from in front, eyes bulging, ocelli arranged in an 

 isosceles triangle on the vertex, the anterior angle extremely 

 obtuse, the anterior member less than 1 diameter from lateral, 

 lateral members nearly as far from each other as from margin 

 of eye: front broadly carinate in the middle and deeply ex- 

 cavate behind the antennae, the excavations not margined be- 

 hind; antennae 38-jointed. nearly as long as body, basal joints 

 stout, flagellum filamentous, opaque and hairy; face wider 

 than long, clypeus foveate laterally, cheeks shorter than short 

 diameter of the eye. Pronotum and pleurae divided trans- 

 versely, the latter widening posteriorly and polished on the 

 disc, middle lobe of mesonotum prominent in front, the parap- 

 sides and lateral margins behind costate, sternae and pleurae 

 separated by a costate furrow, hind margin of pleurae also 

 marked by a costate furrow, the disc polished; scutellum 

 divided transversely before hind margin by a costate furrow, 

 the disc triangular, depressed apically, a broad costate groove 

 basally; metanotum very coarsely rugose, spiracles nearly cir- 

 cular, pleurae finely rugose, punctate on disc, dorsal and an- 

 terior margins marked by costate furrows. Abdomen as long 

 as thorax, depressed basally, 1st segment longer than wide, 

 tergite strongly carinate laterally, striate on the disc, a deep 

 furrow between 1st and 2nd, 2nd and 3rd solidly joined, 

 separated dorsally by only a fine line, and 2nd impressed trans- 

 versely at middle, 4th, 5th and 6th transverse, a thin fascia 

 of hairs near apical margins. Hind legs stouter than anterior
