NOTES ON BRACONID^. 61 



occurred to me very sparingly, iu 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 BRACONID^.— VIII. : ON A PART OF 

 MARSHALL'S COLLECTION. 



By Claude Morley, F.E.S., &c. 



While looking through the earlier part of the Rev. T. A. 

 Marshall's collection of Braconidae, 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 Braconflavator, 

 Fab., as an indigenous species (E. 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 Rhag'mm indagator and Hylotrypes 

 hajulus. There is, however, certainly a female of B. Jlavator, 

 Fab., in the Stephensian collection, under the name B. deni- 

 grator, applied by Curtis (B. E. pi. Ixix.) 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. nee Fab.) = 

 Cceliodes scolyticida, Wesm., male and female. Bracon instahilis, 

 Marsh. (Andr6, xv. 1897, 70) from Cornwall (type in Brit. Mus., 

 with a second, both labelled " Botusflemiug"), and B. virgatus, 

 Marsh, {lib. cit. 68) from Cornwall (type in Brit. Mus., labelled 

 " Botusfleming," with a second from Cameron's collection, labelled 

 " Marsh Mills, June 30th "), are new to Britain. B. roberti,
