BRITISH ICHNEUMONS.

It may be superficially recognised by the cylindrical body, broad head, 

 long and often a little stout antennae, and mainly or nearly entirely red 

 abdomen and legs ; the facies are quite distinct from Olesicanipa, which 

 has stouter and unequal mandibles. Schmiedeknecht has served no good 

 purpose in removing i\f. dorsalis to Zaponis, Forst., on account of its 

 lacking areolet, and J/, crassicornis to Diadcgma, which typeless genus 

 of Fr)rster he uses entirely differently from mv application of it (Ichn. 

 Brit. iii. 274), on account of its centrally unanglcd radius which differs in 

 no \\"a\" from that of other ilLloboris species.

A black species with the deplanatc postpetiole and transverse second 

 and third segments castaneous; legs unicolorous red throughout; areolet 

 wanting; thorax piIo.se with the petiolar area extending beyond centre 

 of metathorax ; lower basal nervure oblique and postfurca! ; terebra 

 sonu'what longer than basal segment. Length, 7-8 mm. 



'I'he only known species with no areolet. 



It is of uncommon occurrence in Prussia, Sweden, I'^rance and Belgium 

 in July and August. Ikidgman found it in Heigham osier carr and at 

 Horning Ferry in the Norfolk Broads during June and August ; and it is 

 certainly rare with us, since my single male was swept from a weedy ditch 

 at East Bridge, near the Suflolk coast, so long ago as the loth July, i()oo.
