segments infuscated, the flagellum of antennz black, wings very iridescent, the 
basal half infuscated, the stigma dark testaceous, the costa and nervures black, 
the 3rd abscissa of the radius as long as the basal 2 united, the 2nd transverse 
cubital nervure faint. There is a smooth elevation, a little longer than wide, on 
the base of the 2nd abdominal segment, in the centre; there is a transverse 
curved furrow across the 4th segment near the base. The abdomen is longish 
oval and is as long as the head and thorax united. Male. Length 2.5m.m.

Rufo-testaceous, the antenne, centre of occiput, broad bands on the 3rd and 
4th abdominal segments, extending laterally to the outer fourth, that on the 
3rd transverse at the apex, on the 4th rounded, the other segments are entirely 
black. Legs coloured like the body, the middle tarsi infuscated, the apex of the 
hind tibie and the hind tarsi black. Wings hyaline, slightly tinged with 
fuscous, the stigma and nervures fuscous ; the recurrent nervure is received at a 
distance from the transverse cubital, the 3rd abscissa of the radius is longer than 
the basal 2 united Male. Length 2.5. 
Smooth, shining. Stemmaticum black. Temples sharply, roundly narrowed, 
the occiput transverse. Parapsidal furrows distinct on the basal three-fourths. 
Bracon consonus, sp. n. 
Testaceous, the antenne, apex of hind tibie (about the apical fourth) and the 
hind tarsi, except the base of the joints, black ; wings fuscous hyaline, the apex 
lighter coloured, the stigma and nervures fuscous ; the 3rd abscissa of the radius 
shorter than the basal 2 united; the 2nd transverse cubital nervure faint. 
Smooth shining, the 2nd abdominal segment with a clearly defined area, tri- 
angular, wider than it is long, ending ina short keel and bordered by wide 
furrows, the sides is an irregular longitudinal furrow, the apex of which is 
broadly rounded inwardly ; before this curved part it is dilated ; the Ist trans-
