Curtis, B. E., 688, pi. 320. Long. If ; alar. exp. 3| lin. 
The c? is similar, with only the usual sexual differences in the 
antennae and abdomen. Two small indistinct foveas at the base of the 
scutellum serve also to distinguish it from Bh. rosm. 
The absence of the areolet, mentioned by Curtis above, is not a 
constant character ; in some specimens it is visible, in others it is 
obliterated on one side only. 
In Mr. Walker's collection and my own. Mine were taken in 
Epping Forest. The gall is at present unnoticed.

BY THOMAS DESVIGNES. 
PiMPLA EuncoLLis, Crav., iii, 153, Earn, vi, sec. 3. 
P. variegata, Eatz., Ichn. der Eorstins. i, p. 118, No. 21. 
Long. 3 1 lines. Eeared both by Eatzeburg and Mr. Barrett from 
Tortrix Buoliana. 
PiMPLA OPACELLATA, u. s. (Grav., iii, sec. 6). 
Long 4 linearum. 
Abdomine nigro. Ooxis et trochanteribus nigris. Pedibus rufis, 
femoribios posticis apice nigris. Tiliis anteriorilus externe fuscis, pos- 
ticis tarsisque nigris. Antennis gracilihus, longitudine corporis parwn 
hrevioribus. Acubus trienti abdominis longitudine cequalibus. 
Sead— Much, broader than long ; face hoary, the margins adjoining the 
eyes perpendicular ; forehead above the antennse depressed, exca- 
vated. AntenncB slender, not so long as the body, TJiorax gibbose, 
siib-cylindrical ; metatborax strongly punctate. Wings clear ; 
stigma and radius black, the former with a milky spot at the base ; 
areolet oblique, sessile, all the nervures black. Legs red ; coxa?, 
trochanters, apex of hinder femora, tibiae and tarsi black. An- 
terior tibiae exteriorly fuscous. Abdomen finely punctate ; 1st seg- 
ment with a broad, flat, elevated surface ; the incisions between 
the segments rather deep and very distinct ; the 5th segment 
narrow, but transverse ; aculeus stout — one-third the length of 
abdomen. 
This insect, apparently hitherto undescribed, was reared by Mr. 
Barrett, of Haslemere, from a pupa of Psyche opacella. 
Mr. Barrett has kindly presented me with both species.
