late, the disc traversed by four longitudinal (central pair 

 united anteriorly) and numerous fine transverse carinae, 

 posterior face 5-areolate. Abdomen basally depressed, com- 

 pressed apically, each segment with a transverse fascia of hairs 

 posteriorly, 1st tergite less than twice as long as wide, ligulate 

 and margined at the sides, 2nd and 3rd quadrate, separated 

 • only by a faintly impressed line, 3rd narrowing somewhat 

 apically and marked by a faint line across anterior sixth, 4th to 

 8th successively shorter, ovipositor longer than abdomen. Legs 

 long and slender, hind femora scarcely longer than coxae and 

 somewhat compressed. 



Wings reaching tip of body, yellowish brown, a transverse 

 hyaline band below parastigma, nervures dark brown, stigma 

 lanceolate and ochraceous, radial cell short and narrow, 1st

Biroia ferruginea, n. sp. 



$ 10 mms. long. Smooth and shining, punctate and 

 hairy; ferrugineous to the metathorax, metathorax and middle 

 legs brownish black to black, hind legs and abdomen deep 

 black and polished. 



Head transverse, wide between the eyes, which are pro- 

 minent and bulging, viewed from in front triangular; ocelli 

 arranged in an isosceles triangle on the vertex, the anterior 

 angle of which is obtuse, lateral members further from the 

 eye than from each other; front excavated and margined be- 

 hind to ocelli ; antennae joined close to the eye, widely separate, 

 lateral emargination continued around the base, almost con- 

 fluent directly between the eyes, 1st and 3rd segments small, 

 2nd stout, half as wide as long, flagellum filamentous, opaque 

 and hairy; face longer than wide, narrowed and convex below, 

 lateral margin foveate beneath eye, labrum nearly quadrate, 

 cheecks almost as long as eye. Pronotum with two transverse 

 carinae, pleurae concave; mesonotum flatly convex, mesosternae 

 bulging, separated from pleurae by a broad costate furrow; 

 disc of scutellum triangulate and depressed apically, basally 

 bifoveate, grooves separating thin pleurite between the meso- 

 pleurae and metapleurae costate; metanotum areolate. Ab- 

 domen depressed, 1st, 2nd and 3rd segments subequal, less 

 than twice as long as wide, 1st bicarinate at the base, 2nd with 

 a transverse groove at about the middle and separated from 

 3rd by a thin furrow, 4th to 8th progressively smaller, each 

 segment with a transverse fascia of hairs posteriorly. Hind 

 legs longer than the anterior ones, coxae stout, femora short 

 and compressed.
