An insect was sent to Mr. BK. A. Fitch, by Mr. E. A. 
Butler, which I believe to be this species, although it 
differs slightly from Holmgren’s description, in that the 
8rd segment is hardly transverse, and the hind coxe 
entirely black.

This species is recorded on the strength of a specimen 
sent by Mr. E. A. Fitch, which was captured at 
- Wymondley, Herts, in August, 1880, by Mr. E. A. 
Butler. It differs slightly from Holmgren’s description, 
in having a yellow line under the wing.

the abdomen much shorter and slightly wider, the other
