vitrert priaeipally in having the fimbria at the apex of the abdomen 

 bright fulvous, and in having a dark margin to the wings. This 

 species appears in July and August, and has only been taken at 

 AViudsor and at Sidmouth, South Devon, on the flowers of the bram- 

 ble, on High Peak, and at Brundall near Norwich.

Male. Length 3^—±^ lines. — Closely resembles the female ; the 

 pubescence on the face more dense, longer, and inclining to fulvous ; 

 the antennae as long as the thorax ; the posterior tibias and tarsi 

 rufo-testaceous, the tibias having a dark stain beneath ; the apical 

 joints of the other tarsi rufo-testaceous. Abdomen oblong-ovate,

This is perhaps the commonest species found in this country, 

 and also generally distributed throughout Europe. Sir John 

 Bichardson found it on the south of Lake "Winnipeg. It ap- 

 pears early in April ; I have taken it as late as .1 uly. It is 

 commonly found on the dandelion. Although so numerous, I have 

 never met with colonies ; neither has it been observed to be attacked 

 by Stylops.

A. nigra, cinerascenti villosa, facie antice albo barbata, tibiis 

 posticis apice tarsisque testaceis.
