British Braconide. 25 
Labial palpi 4-jointed ; stigma elongate, attenuated, emitting 
the radial nervure at one-fourth of its length, which fourth is 
about equal in length to the Ist abscissa. Second segment of the 
abdomen entirely smooth. 2 Black, shining, pubescent ; mandibles 
and palpi rufous. Antenne somewhat longer than the body, 
24-jointed, the first 3 or 4 joints rufous. Prothorax transversely 
wrinkled ; mesonotum traversed by an impressed line issuing in a 
rounded fovea before the scutellum ; metathorax not shining, beset 
with whitish hairs, truncate posteriorly. Wings hyaline; squa- 
mulze brown ; nervures and stigma reddish-brown, sometimes very 
pale. Legs rufotestaceous ; last joint of the tarsi elongate, incras- 
sated, with minute claws. Abdomen spathulate, as long as the 
thorax ; Ist segment finely striolate, pubescent, carinate in the 
middle, twice as wide at tle extremity as at the base, with incon- 
spicuous tubercles. Terebra hardly exserted. ¢ similar ; antenn 
longer, 28-33-jointed ; Ist segment almost linear ; 2nd and follow- 
ing narrower than in the 9, forming together an elongate oval. 
Length, 1-14 lines; exp., 24-3 lines. 
Var. ¢@ Form more slender; head not so much flattened; 
antenne longer, 36-jointed; stigma more attenuated, almost

Labial palpi, and stigma, as in the preceding. Second segment 
of the abdomen striolate at the extreme base. ‘The largest species. 
@ Black shining. Antenne 30-35-jointed, the two basal joints 
more or less testaceous. Medial furrow of the mesonotum broad and 
deeply sunk; metathorax densely pubescent. Wings slightly infu- 
mated; nervures and stigma fuscous. First abdominal segment with 
salient tubercles, striolate, with a small medial space triangular and 
smooth ; apex of the abdomen more acuminate than in G’. affinis ; 
terebra longer, its valves incrassated and flattened. The other 
characters are the same as those of G.affinis. 4 similar ; 2nd abdo- 
minal segment reddish towards the base ; one ¢ in my collection 
has 30-jointed antenne, like the 9. Length, 1% lines; exp, 
3? hues. 
Found in England and Ireland, but much more rarely 
than the other species.
