vitrea principally 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 

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

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

Female. Length 4-5 lines. — Black ; the face with thin cinereous pubes- 

 cence ; a line of white silky pile at the inner margin of the eyes ; 

 the clypeus strongly punctured. Thorax clothed above with ferru- 

 ginous pubescence ; wings hyaline, the apical margins slightly 

 clouded ; the tcgulae and nervures rufo-testaceous ; the pubescence 

 on the metathorax and that beneath cinereous ; the intermediate 

 tarsi and posterior tibiae and tarsi fulvous ; their pubescence pale 

 fulvous ; the floccus on the posterior trochanters white. Abdomen 

 ovate, slightly shining, and closely punctured ; the apical fimbria 

 bright fulvous. B.M. 



Male. Length 3|-4J 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 tibiae and tarsi 

 rufo-testaceous, the tibiae 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 

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

 pears early in April; I have taken it as late as July. 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.

 posticis apice tarsisque testaceis.
