A black and grey-pubescent species. Head transverse and a little 

 constricted behind the eyes, with mandibles flavous ; frons feebly 

 impressed, with a distinct central longitudinal carina. Metathorax trans- 

 versely striate ; mesopleurae strongly punctate and nearly dull. Scutellum 

 diffusely punctate, centrally nitidulous, and laterally margined to beyond 

 its centre. Abdomen with the second segment apically and three follow- 

 ing entirely dark flavous, of which the third bears a short black lateral 

 line ; petiole with no lateral foveae. Legs flavous with the front coxae 

 and trochanters black-marked ; hind legs dark flavous with coxae and 

 trochanters and the base of femora broadly black, their tarsi ferrugineous. 

 Wings slightly clouded with stigma fulvous, tegulae piceous, the recurrent 

 nervure emitted from centre of areolet and nervellus intercepted a little 

 below the centre. Length, 16-20 mm. 



Found rarely in Sweden during early August and at Aix-la-Chapelle 

 (Holmgr.); at Genck in Belgium during August (Tosq.), and in France 

 (Gaulle). Bred from Macaria ( ScniiothisaJ aestimaria by Ferris (Ann. Soc. 

 Fr. 1877, p. 403), and from Lophvrus nifiis by Rondani (sec\)T)j. Bignell 

 raised it in Devon from an unknown host (Entom. 1885, p. 19 ct Tr.

In shape, colour and conformation very like the last species ; but 

 smaller and more compressed, with the metathorax shorter and but finely 

 trans-striale throughout, the speculum nitidulous and subglabrous, areolet 

 broader and emitting the recurrent nervure before its centre, the nervellus
