ferruginous at their apex. Thorax closely and rather strongly 

 punctured, the punctures on the disk less dense than at the sides, 

 clothed with pale fulvous pubescence ; the wings hyaline, the 

 teguhe dark rufo-piceous, the nervures pale rufo-testaceous ; the 

 femora fringed with pale fulvous pubescence, that on the anterior 

 and intermediate tibia? above short and fuscous ; the floccus on the 

 posterior trochanters pale fulvous, the scopa of the tibia? fulvous ; 

 the basal joint of the posterior tarsi fusco-ferruginous ; the claw- 

 joint of all the tarsi rufo-testaceous. Abdomen ovate, the apical 

 margin of the basal segment ferruginous, as are also the sides of 

 the second, which has also sometimes a faint narrow ferruginous 

 margin : the apical margins of the second, third, and fourth seg- 

 ments with a pale marginal fringe, the apical fimbria black. 



Yar. (3. The apical margin of the basal segment only slightly ferru- 

 ginous. 



Var. 7. Abdomen black. (A. conjunctiva, Smith.) B.M. 



Male. Length 5-5^ lines. — In general appearance like var. y 

 female, more slender and with longer antennae, the joints arcuate, 

 the general colouring of the pubescence more inclining to griseous 

 than in the female, except that on the head, which is nearly black ; 

 occasionally the apical margin of the basal segment is narrowly 

 ferruginous, and the second ventral segment has two red niacuke ; 

 these are very inconstant, frequently entirely wanting. B.M. 



Mr. T. B. Bridgman, of Xorwich, took this species in April, near 

 the city, at Eaton, Blundall, and Mousehold Heath, in plenty : they 

 frequented the blackthorn and willowr. The highly coloured varie- 

 ties were less numerous than the darker ones. I took the female 

 some years ago, but have never found the male ; it must be a very 

 local insect.
