NOTES ON BRACONIDZ. 61 
occurred to me very sparingly, in 1906-7, in the Isle of Purbeck, 
Dorset, in company with numerous examples of the better-known 
forms, and my captures included individuals of every shade be- 
tween the darkest representatives of ab. fumosa and the typical 
form. The fact that I have not taken any females referable to 
ab. fumosa affords no good reason for supposing that this dusky 
aberration is confined to the opposite sex, for the total number 
of females that has rewarded my efforts is very limited.

NOTES ON BRACONIDA.—VIII.: ON A PART OF 
MARSHALL’S COLLECTION. 
By Cxuaupe Mortey, F.E.S., &c. 
Wut looking through the earlier part of the Rey. T. A. 
Marshall’s collection of Braconide, which has now passed from 
the late Dr. P. B. Mason to a resting place in the British 
Museum, in January, I jotted down a few notes, which will 
add several species to the British list, and others of general 
interest. 
I should, first, like to say that my record of Bracon flavator, 
Fab., as an indigenous species (EH. M. M. 1908, p. 269) is quite 
wrong; the insect is in reality Doryctes leucogaster, Nees, a 
common kind along all the coasts of the Mediterranean, and 
known to extend as far north as Central Europe, though no 
mention of it as British exists. It has been several times bred 
from the Longicorn beetles Rhagium indagator and Hylotrypes 
bajulus. There is, however, certainly a female of B. flavator, 
Fab., in the Stephensian collection, under the name B. deni- 
grator, applied by Curtis (B. E. pl. lxix.) to Proterops nigripennis, 
Wesm. ‘This may, of course, be British, though none have 
since been discovered. I found a single female of Bracon im- 
postor, Scop., under the same name in Stephens’s collection. 
This is a somewhat frequent species in Central and Southern 
Europe, preying upon Monochammus sutor, a Longicorn occa- 
sionally introduced into the British docks, though doubtfully 
indigenous, and its parasite may have been similarly imported. 
Bracon initiator of Stephens’s collection (et Wesm. nec Fab.) = 
Celtodes scolyticida, Wesm., male and female. Bracon instabilis, 
Marsh. (André, xv. 1897, 70) from Cornwall (type in Brit. Mus., 
with a second, both labelled ‘‘ Botusfleming’’), and B. virgatus, 
Marsh. (lb. cit. 68) from Cornwall (type in Brit. Mus., labelled 
*‘ Botusfleming,” with a second from Cameron’s collection, labelled 
‘‘Marsh Mills, June 80th”), are new to Britain. B. roberti,
