Heterogyna and Fossorial Hymenoptera. 291 



17. signatns, Panz. Faun. Germ. 53, 15, 



Very like dii)iidiatus, but differing in the following 

 j)articulars : — The 3' has the tibiae without spines, and 

 the posterior femora with a small tooth near the base 

 beneath ; the ? , according to Wesmael, differs in having 

 the petiole of the body slightly thicker and shorter, each 

 of the excavations of the vertex divided in two by an 

 oblique carina, and the tibiae entirely yellow without 

 spots. Thomson says that the tibia also are less spinose. 



Length 11—12 mill. 



The (? only appears to have occurred in England, but 

 I suspect the ? is overlooked for that of the preceding 

 species. The <? has been taken at Swansea by Mr, 

 Dossetor, and at Eaton, near Norwich, by Mr. Bridgman.
