British Braconida. 75 



that of the ? twice as broad as that of the $ . Terebra half as long 

 the abdomen. Length, \\ ; wings, 3 lin. 



Antenna ? 23-jointed; of the $ 28— 29-jointed, stout, longer 

 than the body. Mesothoracic sutures converging into a rugulose 

 depression. Scutellum smooth, shining, with a few lateral punc- 

 tures. Metathorax short, abruptly truncated, rugulose; two 

 medial carinas, more or less distinct, originate from its base, and 

 are parallel as far as the truncation, where they diverge on each 

 side of the posterior concavity. First abdominal segment entirely 

 black and striolated, twice as broad at the apex as it is at the base, 

 and much broader in the ? than in the $ ; tubercles medial. 

 Very distinct from rutilus ; larger and more robust ; metathorax 

 and 1st abdominal segment differently formed ; radial areolet more 

 elongate ; neuration stronger ; legs of both sexes, and abdomen of 

 the 2 , differently coloured ; the characters of the ? have been 

 given to me by Capron. P. terminatus, Nees, stands nearest to 

 this species, but differs in having a rugulose scutellum. The radial 

 areolet is much longer than in falciger. 



I captured two males in 1885 ; one in the same wood 

 with P. rutilus, the other in the Isle of Wight. Capron 

 has taken at Shiere six more males and the only female.

? Perilitus peregrinus, Schaff., F. G., clvi. 



$ . Black ; head concolorous, mandibles rufous ; femora and 

 tibise piceo-rufous, coxeb black, tarsi tipped with fuscous ; base of 

 the petiole pale testaceous. Wings subhyaline, nervures, stigma, 

 and squamulse fusco-testaceous ; radial areolet shorter than in the 

 two preceding species, semicordate, ending half-way between the 

 stigma and the tip of the wing. Abdomen truncated posteriorly. 

 Terebra as long as | the abdomen, its apical half decurved, falcate. 

 The $ is similar, but the petiole is black at the base. Length, 

 li-1?,; wings, BJ-8J lin. 



Var. ? . Antennae at the base, face, and cheeks, rufescent , 

 mouth and legs rufo -testaceous ; hind coxae black. Euthe. 



Antenna ? filiform, not longer than the body, 22— 24-jointed ; 

 those of the $ longer, setaceous, 28-jointed, paler at the base 

 underneath. Form slender. Mesothorax as in the other species. 

 Ante-scutellar fovea much shorter than the scutellum, which is 

 smooth and shining. Metathorax short, rugulose, not quite
