38 AXDRENIDJE. 



Male. Length 4 lines. — Black ; the face and cheeks clothed with 

 long white pubescence, that on the thorax above fulvo-ochraceons ; 

 the femora fringed with long white pubescence ; the teguke rufo- 

 piceous; wings hyaline, iridescent and faintly clouded at their apical 

 margins, the nervures pale ferruginous ; the posterior tibiae and 

 the tarsi rufo-piceous, the former having a black stain beneath, 

 nearly extending to their apex ; the claws ferruginous. Abdomen 

 ovate, shining, delicately punctured, and having a thinly scattered 

 short griseous pubescence, the apex fulvous ; beneath, the margins 

 of the segments have a narrow white fringe. B.M. 



This male closely resembles that of A. albicans : but in the finest 

 condition the face is clothed with white, in A. albicans it is pale 

 fulvous ; the pubescence generally is more inclining to cinereous, 

 the abdomen much more finely punctured, and the second submar- 

 ginal cell is less narrowed towards the marginal than in A. albicans, 

 and the antennae are shorter than in that species. Some of these 

 differences may appear slight : but by them alone the males of many 

 very distinct species of this genus can be distinguished. The Mu- 

 seum is indebted to Mr. Walcott for specimens of this species cap- 

 tured near Bristol.
