Britisli Braconidce. 259 



Haliday calls the palpi rufous, but this is within the 

 limits of usual variation. 



Found rarely by Haliday on muddy coast of north 

 Ireland, In Cameron's collection are two males and 

 three females from Glenlyon, Scotland ; also captured 

 by Sharp at Thornhill, and by me formerly at Loch 

 Rannoch. Brischke bred it at Danzig from Eitpithecia 

 cdmpamilata, Schiiff., and describes the cocoon as solitary, 

 thin, silky, white.

 latus, carinatus. Segmentum Imum vix longius quam latius, 

 lateribus fere parallelis, ruguloso-punctatum, trmicatum, apice 

 medio emai'ginatum, longitudinaliter canaliculatum ; segmentum 

 2 et seqq. laevia, nitida, illud canaliculis 2 arcuatis antice diver-

 curvata, postice concava. Terebra brevissima. Valvula ventralia 

 anum non attingens. Pedes breves, crassi ; posticorum calcar

Black ; palpi pale ; 4 anterior legs rufo-testaceous, hind legs 

 piceous, their tibiae rufescent in the middle ; all the coxee black ; 

 anterior tarsi at the tips, hind tarsi wholly, fuscous. Wings 

 hyaline, squamulse, nervures, and stigma fuscous. Antennae very 

 short, hardly longer than the head and thorax, submoniliform. 

 Body rather shining. Head very finely, mesothorax thickly and 

 more strongly, punctulate ; scutellum smooth in the middle ; meta- 

 thorax thickly and finely punctulate, carinated. Segment 1 hardly 

 longer than broad, the sides nearly parallel, ruguloso-punctate, 

 truncated, emargmate behind in the middle, longitudinally canali- 

 culated ; segment 2, and the rest, smooth and shining ; 2 longi- 

 tudinally trisected by two curved impressed lines which diverge in 

 front ; suturiform articulation curved, concave behind. Terebra 

 very short. Valvula ventralis not reaching the anus. Legs short, 

 stout ; inner spur of hind tibiae much longer than ^ the metatarsus.

This and the following species are very distinct fi-om all described
