British Braconidm. 63 



Taase of the tibise, dull testaceous ; tarsi infuscated, each articulation 

 pale at the base. Abdomen lanceolate ; 1st segment linear, three 

 times as long as wide, without distinct tubercles, pale testaceous 

 .at the base, fuscous at the extremity ; 2nd fuscous, pale at both 

 ■ends ; the rest of the segments fuscous. Valves of the terebra black. 

 $ Similar ; antennse almost as long as the body, 17-jointed ; 

 colours darker than those of the $ , even the forelegs are infuscated, 

 or streaked with fuscous above ; abdomen elongate oval, rounded 

 at the apex. Length, 1 ; exp. 2 lines. 



A common parasite ; I obtained six specimens, com- 

 prising the two sexes, from Siphocoryiie fieniculi, Passerini, 

 the puceron of Foiniculum vtdgare, fennel, and Bignell 

 sent me a male of the same origin. Thirteen others were 

 reared from the pueerons of Baphanus maritimus, the 

 stalks of which plant were loaded with dead aphides. 

 The Bignell collection possesses more than forty speci- 

 mens, the produce of Aphis brassier, L., the puceron of 

 Brassica oleracea, the cabbage, and of some other kindred 

 plants. Trionyx (i.e. Toxares, afterwards Aphidiits) rapse, 

 'Curtis, probably belongs to this species.
