British Braconidce. 101 



spots on the 2d segment, sometimes on the 3d also, fuscous. Ej'es 

 large, vertex narrowed behind. Antennae 42 — 52-jointed, slender, 

 longer than the body. Mesopleiu'ae very finely granulated, some- 

 what shining. Abdomen elongate, obovate, broadest at the end of 

 the 3d segment, then abruptly rounded ; 1st segment half as long 

 again as its apical breadth, which is double the basal breadth ; 

 segments 1 — 3 mmutely rugulose, the rest more shining, punctu- 

 late. Wings hyaline, stigma fuscous, with a pale basal spot ; 2d 

 cubital areolet twice as broad as its length, twice as wide as, and a 

 little longer than, the podiscoidal. Terebra subexserted. Length, 

 2^ ; wings, 4| Im. 



Var. a. Pro- and mesothorax pale, the latter with three dusky 

 stripes ; metathorax pale at the sides. 



In Eeinhard's table of species this is separated from 

 circumscriptiis only by the form of the vertex, which is 

 straight behind the eyes, instead of rounded. The ground 

 colour is a remarkably pale testaceous, almost trans- 

 parent, the coxae and trochanters nearly colourless. 

 According to Wesmael {lib. cit., p. 95, note) the 1st 

 intercubital nervure is slightly oblique. I possess an 

 old female specimen taken at Barnstaple, "which almost 

 certainly belongs to this species, although not in a con- 

 dition to exhibit some of the characters very distinctly. 

 The 52-jointed antennae, the form of the abdomen, &c., 

 show that it cannot be circuimcriptus.

Testaceous, immaculate, or with the metathorax, and abdomen 

 at the base and apex, fuscescent. Eyes large ; vertex behind them 

 with sti'aight sides ; gense of the ^ ending in a vertical tooth, those 

 of the 5 unarmed. Antennae 40 — 44-jointed, as long as the body 

 Mesopleurae very finely granulated, somewhat shining, the fovea 

 obsolete. First abdominal segment of the ^ ^ longer, of the $ 

 only a little longer, than its apical breadth, the apex twice as broad 

 as the base ; segment 2 quadrate ; 3 not broader than 2, its apical 

 margin and the remaining segments punctulate, somewhat shining. 

 Wings hyaline, stigma testaceous, sometimes fuscous at the apex ; 

 neuration as in the preceding ; radius of the hind wings obsolete.
