Female. Length 4^-5 J lines. Black ; the clypeus has a cloth- 

 ing of fulvous pubescence, above which it is black. Thorax : 

 the disk thinly clothed with fulvous pubescence, on the sides 

 and metathorax it is paler ; wings hyaline, the nervures ferru- 

 ginous, the tegulse piceous ; the pubescence on the legs rufous, 

 the scopa fulvous, the claws ferruginous, the pubescence on the 

 tarsi beneath ferruginous, the floccus pale fulvous. Abdomen 

 ovate, shining, closely and finely punctured ; the margin of the 

 basal segment and those of the three following have a fascia of 

 pale fulvous pubescence, that on the basal segment usually 

 more or less obliterated; the apical fimbria sooty-black. B.M. 



Male. Length 3^-5 lines. Black; the face densely clothed 

 with black pubescence, usually intermixed with a few fulvous 

 hairs ; antennae half the length of the thorax, the latter clothed

This is a very abundant species in the London district, and 

 appears to be generally distributed over the country. It has 

 been received from Scotland. The males vary considerably in 

 size as well as in colour ; when long exposed they become en-

 cimen of the male ; and it is pretty certain that A. articulata is
