St. Melittse, Kirby 31. A.— Steph. Cat ah No. 578i). 
Intense black ; wings somewhat rounded on the hinder margins ; milk 
white, stained with dusky towards the costa, which is deep black : legs 
pitchy, with the 4 anterior tarsi reddish : abdomen pale on its edges. 
Found, very rarely, near London ; and in Suffolk ; in the spring. 
The insects included in this genus are all of the utmost rarity near 
London ; but under favourable circumstances, and in some localities, 
numerous examples have been observed and captured. — It would ap- 
pear from the diversity in the form of the wings and other minor cha- 
racters, that there were several distinct species : I have, however, been 
unsuccessful in obtaining more than two, viz. Melittse and Dalii. 
The following are the indigenous species recorded, aIz. : — 
Sp. 1. Melittse /lirfty. — Barham : Clapham. 
2. Kirbii Leach. — Devonshire. 
3. Haworthi *.S^e/>/;e».<. — Chelsea. 
4. Spencii Pichcring. — Ilammersmitb. 
t). Dalii Curtis. — E})ping and Dorset. 
The St. tenviicornis Kirby is the t}^ie of a distinct genus, called Elen- 
ciiL'S by Curtis, and synonymous with his El. Walkeri, of which I 
once brushed a specimen from off some high grass near Hertford in July. 
One other species, viz. Halicto|)bagus Curtisii, closes the account of the 
ascertained British species of this singular order of insects.
