Insects. 1927 



pubescence ; the antennae nearly as long as the head and thorax. 

 Thorax thinly clothed on the disk with a little pale pubescence ; the 

 tegulae piceous ; wings sub-fuscous ; the legs nigro-piceous, having a 

 long pale pubescence ; the posterior tarsi, and the apical joints of the 

 intermediate and anterior tarsi, ferruginous ; the basal joint of the 

 tarsi fulvescent within. Abdomen oblong-ovate ; the margins of the 

 segments rufo-piceous, the apical segment piceous. 



This male closely resembles the same sex of A. Gwynana, of which 

 it may be a permanent variety ; but as it differs from the usual cha- 

 racters of that male, I hesitate to consider it synonymous. It is found 

 near London in the spring.

This species I never met with near London : I once took a speci- 

 men or two in Hampshire. Mr. Dale informs me that some seasons 

 it is not uncommon at Glanville's Wootton. One peculiarity appears
