face ; its apex with a semicircular depression. Abdomen punctured, 

 witli transverse depressions ; the first segment twice longer than it 

 is wide at the apex ; the apical slope depressed ; the apex of the 

 segment not raised in the centre ; the second segment longer than 

 wide ; the third slightly longer than wide ; the others wider than 

 long. Metathoracic spiracles small, almost round. Parapsidal 

 furrows deep at the base of mesonotum. 



I only know the $ of this genus. Its characteristics are the 

 uniformly fuscous wings, red body colour, long first abdominal 

 segment and transverse median nervure in hind wings broken in 

 the middle. The similarly coloured species of Pimpla may be at 

 once known by the transverse median nervure in hind wings, being 

 broken above the middle. In Ashmead's arrangement the genus 

 would come in near Itoplectis and Ercmochila. 



Delaulax rufus, sp. nov. 



Eufous, the antennae, the centre of the front and vertex broadly, 

 the centre of the occiput broadly, the line narrowed above and con- 

 tinuous with that on the vertex, the sides of the mesonotum broadly, 

 the parts at the sides of the scutellums broadly, the mesosternuni 

 and the hind tibite and tarsi, black. Wings uniformly fuscous viola- 

 ceous, the stigma and nervures black. J . 



Length 9-10 mm.

Shining, covered with white pubescence on the body and legs, on 

 the face with black hair. Median segment closely, strongly punc- 

 tured, a broad smooth space down the middle of the metanotum ; 

 the lower part of the metaplem-ae only weakly punctured. Basal 

 slope of the first abdominal segment smooth, the rest of it strongly, 

 but not closely punctured ; the second to fourth are more closety 

 and quite as strongly punctured ; the fifth is more weakly punc- 

 tured ; the sixth smooth and densely pilose ; the apices of all the 

 segments are smooth. 



HOLCOPIMPLA, gen. nov. 



Median segment neither keeled nor areolated, a wide, distinct 

 furrow down the middle ; the spiracles small, oval. Scutellum 

 roundly convex, its sides not keeled. Parapsidal furrows distinct on 

 the basal half. Clypeus separated from the face by a narrow furrow ; 

 it is largely depressed on the apical half ; the depression is narrowed 

 above. Abdomen closely punctured, the segments depressed at the 

 base ; the first segment longer than wide, the second as long as
