Head black, laterally buccate, broader than thorax, of ? nearly cubical ; 

 clypeus apically incrassate ; mandibles centrally red ; $ with face, clypeu.s 

 and sometimes the external orbits, white. Antennae black, filiform, a 

 little attenuate apically ; of $ centrally white-banded, of <$ with scape 

 often white-dotted beneath. Thorax black, humeral callosities of 1^ some- 

 times white ; areola sub-rectangular, of $ longer than broad, of $ sub- 

 quadrate. Scutellum black. Abdomen black, elongate, of S sub-linear ; 

 apical segment of 5 white-marked ; post-petiole narrow, shagreened or 

 sub-aciculate, of S shortly deeply canaliculate in the centre ; gastrocaeli 

 obsolete, with the intervening space aciculate ; terebra shortly exserted, as 

 long as the two apical segments. Legs normal, red with coxae and apices 

 of hind femora and tibiae black ; front coxae of $ occasionally white- 

 marked. Wings hyaline, stigma and tegulae black ; areolet pentagonal, 

 narrowed above. Length, 12 mm. 



Li conformation the S resembles that of Cratichiieuinon fabricator. 



This species occurs among undergrowth in June, in Germany, France, 

 Hungary and Belgium ; but its inclusion in our fauna rests, as far as I am 

 aware, entirely upon Stephens, who says it is rare, but has been taken near 

 London, in July.
