Ichneumonidons Group Tryplwnidcs schizodonti. 435 



acuminately explanate at the sides ; antennas shorter 

 and consisting of 21 (not 20, as in the latter) flagellar 

 joints and the scutellum is more convex and coarsely 

 punctate (cf. also Brischke, Schr. Nat. Ges. Danz., 

 1878, no. 6, p. 112). The areolet and sculpture will 

 also distinguish it from H. fissorius. It appears to 

 only differ from H. megaspis, Thorns., in the sculpture 

 of the metathorax and second segment, and in the 

 colour of the hind tibias.]

 (Blackheath), Norfolk, Suffolk, Herts., Kent, Sussex, 

 Surrey, Isle of Wight, Devon. Also from Nantua and
