6. Bracon longicollis, Wesm. 



Braco longicollis, Wesm., Nouv. Mem. Ac. Brux., 

 1838, p. 28, ? . 



Elongate, black ; raaudibles, sides of the abdomen wholly, or 

 the basal half, belly, and legs, testaceous : middle and hind coxae, 

 and claws, black : middle and hind femora more or less infuscated 

 at the base; metathorax subelongate, with a medial longitudinal 

 carina (often obsolete) ; 2d and following abdominal segments very 

 finely aciculated, somewhat shining ; wings subhyaline ; terebra 

 \ as long as the abdomen, the valves stout, subclavate. <? ? • 

 Length, 1^ ; wings, d\ lin. 



Var. ? . Carina of the metathorax obsolete : jsosterior femora 

 with a fuscous line above and below, their tibiae fuscous in the 

 middle. Length, 1^ ; wings, ^ lin. Two specimens taken by 

 Bignell. 



AntennfE $ 29— 33-jointed, as long as the body ; palpi black ; 

 mandibles testaceous. Parallel to the metathoracic carina are a 

 few rugulosities. Abdomen elongate-oval, black; the lateral mar- 

 gins of segments 1 — 3 — 4, sometimes of all, together with the 

 belly, testaceous. Segment 2 always finely rugulose, and generally 

 the rest, but the sculpture of these is frequently so minute that 

 they appear shining. "Wings not quite hyaline, with an obsolete 

 whitish mark under the fuscous stigma. 



The undescribed $ has 32-jointed antenna?, longer than the body. 

 Metathorax indistinctly carinated, but with some longitudinal 

 wrinkles. Sculptm-e and colours of the abdomen as in the more 

 strongly marked females ; segment 2 aciculated. Fore femora 

 and tibi« shghtly infuscated ; middle and hind femora black, their 

 tibia; tipped with black, and the tarsi fuscous. 



Easily distinguished from the preceding species. It 

 is smaller ; the head and thorax are uniformly black, 

 the femora marked with the same colour ; the terebra 

 is shorter ; and it shows no disposition to run into 

 varieties. 



Wesmael's estimate of the length of the terebra ^— ^ 

 of the abdomen, is again somewhat too great for the 

 British specimens.
