83. Bracon degenerator, n. s. 



Niger, nitidus ; segmenti Imi lateribiis, pedibusque testaceis, 

 coxis nigris, fenioribus tibiisque posterioribus infuscatis ; articii- 

 latione suturiformi late sinuata ; alis fuscescentibus, litura obsoleta 

 hyalina, anticarum nervo pobrachiali transverse vix interstitiali ; 

 terebra abdominis apice compressi trientem lequante. 



Black, shining ; sides of 1st abdominal segment, and legs, testa- 

 ceous, coxae black, posterior femora and tibiae infiiscated ; suturi- 

 form articulation broadly sinuated ; wings • somewhat fuscescent, 

 with an obsolete hyaline streak ; pobrachial transverse nervure of 

 the fore wings hardly interstitial ; abdomen compressed at the 

 apex ; terebra ^^ of its length. $ . Length, 1 ; wings, 2| Im. 



Antennae 28-jointed, as long as the body and the terebra together. 

 Metathorax and abdomen smooth ; the latter soft, shrivelled after 

 death, leaving pale interstices between the segments, elevated 

 posteriorly, compressed, and truncated. Four anterior tarsi at the 

 apex, and hind tarsi altogether, fuscous. Pobrachial transverse 

 nervure not exactly interstitial, subevected, showing a tendency 

 towards the Exothecides. This, however, may be merely acci- 

 dental. 



One ? taken in Leicestershire.

Black, shining; palpi blackish; mandibles, 1st abdominal seg- 

 ment at the sides, a streak at the basal angles of the 2d, the knees, 

 and often the fore tibiae entirely, flavo-testaceous. Wings fusce-

 shining. Segment 1 not margined, elevated in the middle. Tere-

I have not seen the ^ , which Nees in no way dis- 

 tinguishes from the ?. Antennae ? 25 — 27-jointed, as 

 long as the body. Belly fiavo-testaceous, with 2 or 4 

 round l)lack sjiots near the base, and sometimes behind 

 theui 2 longitudinal l)laek bauds extending to the anal 

 segment. The legs are variable ; the fore tibiae ma}' be 

 entirely, and the others more or less broadly at the base, 

 testaceous. According to Nees and Wesmael, the abdo- 

 men during life exhibits pale sutures, and looks as if
