Female. Length 4 lines. Black ; the face nearly naked, having 

 only a few scattered griseous hairs ; the lateral channels of the 

 face, which in this species are continued as high as the vertex 

 of the eyes, are slightly curved inwards towards the stem- 

 mata, and are clothed with fuscous pile. Thorax shining, and 

 having a few pale hairs at the sides of the metathorax ; the disk 

 rather strongly punctured and shining, the metathorax opaque ; 

 the tegulae piceous, the wings subhyaline, the nervures fuscous ; 

 the first recurrent nervure received near the apex of the second 

 submarginal cell ; the floccus white, the scopa fuscous above, 

 silvery beneath. Abdomen glossy, widest towards the apex, the 

 margins of the intermediate segments slightly depressed, and 

 having a narrow fringe of short white pubescence, the first two 

 widely interrupted, the apical fimbria rufo-fuscous. B.M. 



Male. The clypeus and a small angular spot on each side white, 

 the clypeus having two minute black dots : the antennae shorter 

 than the thorax, the latter shining, and having a very thin pale 

 ochraceous pubescence : wings as in the other sex ; the legs 

 have a cinereous pubescence, and the apical joints of the tarsi 

 are ferruginous. Abdomen lanceolate, and having a scattered 

 griseous pubescence, that at the apex pale and glittering. B.M. 



This species is not met with in the London district, but in the 

 north of England it does not appear to be uncommon. It is 

 frequently received from Scotland; in 1852 both sexes were 

 taken in tolerable plenty, and dug out of the same burrows : 

 this circumstance, in connexion with the fact of both insects 

 being usually received at the same time from Scotland, removes 

 any hesitation in considering them one species. A specimen or 

 two has occurred at Weybridge.
