fusco-cinereous in another, that on the cheeks white. Thorax 

 clothed above with r ufo-fulvous pubescence : on the metathorax, on 

 the sides and beneath it is nearly white ; the wings hyaline, their 

 apical margins faintly clouded, with the nervures pale ferruginous ; 

 the legs have a pale rufous pubescence, the fringe on the femora 

 and the floccus on the posterior trochanters white ; the posterior 

 tibia?, the apical joints of the anterior tarsi, and the intermediate 

 and posterior pairs rufous, the scopa fulvous. Abdomen obscurely 

 nigro-aeneous, subovate, convex, and thinly sprinkled with short 

 pale fulvous pubescence, the apical margins of the segments with a 

 whitish fringe, the apical fimbria somewhat fulvous. B.M. 



Male. Length 5 lines. — The face witli pubescence similar to the 

 female, with a little fulvous intermixed at the insertion of the an- 

 tennae, which are as long as the thorax, the joints arcuate. 

 Thorax aud wings as in the other sex ; all the tarsi and the pos- 

 terior tibiae ferruginous, usually more or less fuscous at the base,

This must lie a very local species : Kirby took it once at Barham, 

 and in his collection there is one female and two males ; the Museum 

 collection contains a male from that of Mr. Stephens. I have a 

 female, taken at Aldershot some years ago, that I have considered 

 a variety of the species ; this has white pubescence on the face ; in 

 other respects it closely resembles it.
