is interstitial ; the apical nervures in the hind wings are interstitial ; the radial 
cellule long, reaching to the apex of the wing; the radius issues from the middle 
of the stigma Eyes large, reaching to the base of the stigma. Mandibles 
almost equally bidentate. Parapsidal furrows distinct at the base. Metano- 
tum long, transversely striated, the base with a semi-circular area on either side ; 
the spiracles small. oval; the slope is gradual, oblique. Abdomen four times 
as long as the thorax, strongly compressed, curved roundly, the first segment 
shorter than the second, its apex dilated. Legs long, the middle tibie with two 
spurs, he long spur of the hinder nearly half the metatarsus ; the tarsi closely, 
distinctly spinose. 
The apex of the thorax does not project into a neck, but is transverse and very 
little narrowed. The mandibular teeth almost equal in length. Clypeus not 
separated from the face by a distinct furrow ; its apex broadly rounded, oviposi- 
tor projecting one-third of the length of the abdomen. 
This genus resemb’es in the body form Podogaster and certainly it is closely 
allied to it, but may readily be separated from it by both the transverse cub- 
ital nervures being united to the radius and clearly separated at their junction 
with it, by there being a distinct pterostigma, by the transverse median 
nervure being interstitial and by there being two arez on the base of tho 
metanotum. 
Butanygaster brevipennis, sp. n. 
Black, the mandibles except the teeth, palpi, tegule, and almost the basal 
half of the first abdominal segment pallied testaceous,the apices of the second, 
third and fourth ventral segments of a deeper, darker testaceous, the four front 
legs testaceous, the hinder black, except the apical joint of the trochanters, 
the apex of femora narrowly and the spurs which are testaceous ; wings 
clear hyaline, the stigma and neryures black. Female. 
Length 9 m.m. ; terebra 2 m.m. 
Smooth, shining, almost bare, the metanotum slightly depressed in the middle, 
finely closely transversely striated ; the metapleure and the hind cox finely 
closely punctured, the uppe: part of the mesopleure raised; below is an 
oblique, smooth shallow depression, the rest is sparsely weakly punctured. Face 
sparsely, weakly, but distinctly punctured 
Charops peronatus, sp.n. 
Black, the head and thorax densely covered with silvery pubescence, the 
apical abdominal segments with a shorter and sparser pile, the mandibles, palpi, 
underside of antennal scape and the tegule, pallid yellow, the ventral surface of 
the second and the base of the thi d ventral surface pallid testaceous ; legs, 
the anterior with the coxe black, the trochanters, the outerside of the tibie 
and the spurs pallid yellow, the rest testaceous ; the middle with the cox, basal 
joint of trochanters, almost the basal half of the femo a and the apical fourth of 
the tibie black ; the rest of femora rufo-testaceous, the tibie and tarsi pallid 
yellow, the apices of the tarsal joints blackish ; the hind legs black, except for a 
pale yellow band, commencing near the apex of the basal fourth and extending
