British Braconidfe. 139 



Caput, ut videtur, magis ciibicum, genis deorsum productis, dila- 

 tatis, oculis minoribus, autennis multo tenuioribus, maris 22-, 

 femince 16-articulatis, ultra medium incrassatis, flagelli basi rufa. 

 Abdomen minus ovatum juxta basin angustatum, lateiibus magis 

 parallelis ; maris rima anali potius cordiformi vel subcirculari, 

 subtus emarginata, ibidenique ciliata, limbo undique depresso 

 splendente ; pedibus denique feminie fere totis testaceis. 



Black ; abdomen immaculate ; palpi black ; mandibles rufescent 

 at the tips ; legs J rufo-testaceous, including the trochanters, 

 coxae black, tarsi and tips of hind tibite fuscescent ; of the S' the 

 four anterior femora are black, testaceous at both ends, hind 

 femora entirely, and their tibiie at the apex, black. Very like 

 C. sulcatus, Nees, but distinguished as follows : — Head less trans- 

 verse, more orbicular, cheeks produced downwards, and somewhat 

 dilated ; eyes smaller ; antennae more slender, of the i 22-, of the 

 5 16-jointed, compresso-dilated beyond the middle, the last 3 — 4 

 joints abruptly diminishing; 1st joint of the flagellum testaceous. 

 Abdomen less oval, more contracted at the base, the sides more 

 parallel; anal aperture of the ^ narrower and longer, i.e., more 

 cordiform, emarginate on the lower side and there ciliated, with a 

 depressed shining margin. ^ J . Length, 1^ ; wings, 2f lin. 



The colour of the legs in the female renders it pro- 

 bable that this may be C. imrcicornis, Thoms., Opusc. 

 Ent., vi., 1874, p. 579, c? ? , but not of Schaffer and 

 Wesmael. The sexes differ only in the colour of the 

 femora, and as they were taken together I presume that 

 they are correctly paired. 



Described from two pairs captured in Northants, and 

 another from Cadder Wilderness, near Glasgow, in 

 Cameron's collection; also a male taken by Fitch at 

 Maldon.
