26. Bracon colpnphorus, Wesm. 



Braco colpophorus, Wesm., Nouv. Mem. Ac. Brux., 

 1838, p. 46, ? . 



Black ; mandibles at the apex, palpi, sides of segment 1, or 

 1 — 2 — 3, femora at the apex, fore tibiae entirely, posterior at the base, 

 testaceous. Wings dark fuscous, with a hyaline streak. Body en- 

 tirely smooth and shining. Suturifiirm articulation almost straight. 

 Terebra about \ abdomen. ^ ? . Length, 1^ ; wings, 3^ lin. 



Entirely black above, except the margins of segments 1 — 3 (only 

 of segment 1 in British examples), and very shming. Antennae 

 28-jointed in one J (25-, accordmg to Wesmael), as long as the 

 body. Belly testaceous, darker posteriorly. Wesmael gives the 

 length of the terebra differently in two places, as \ and | abdomen ; 

 the former appears to be more correct. The ^ is similar ; antennae 

 30-jointed. 



Fitch has taken both sexes at Maldon, and I have a ? 

 from St. Albans. The B. colpophorus ? of Ratzeburg 

 (Ichn. d. Forst., iii., 72) is doubtful, for he describes the 

 wings as only a little infuscated, and further compares 

 it with his B. pdlucidus (see sp. 27 infra, ad fin.). It 

 was bred by Bach from pods of Ervum hirsutum, tenanted 

 by Apion craccce, L., and Apion difficile, Hbst.

Braco discoideus, Wesm., Nouv. Mem. Ac. Brux., 1838, 

 p. 45, ? ; Ratz., Ichn. d. Forst., ii., 38, iii., 36, a" ? . 



Black,; mandibles, palpi, lateral margins of the abdomen nar- 

 rowly, belly, and legs, testaceous ; hind coxae, hind tibiae at the 

 apex, and hind tarsi, black or blackish ; metathorax smooth ; wings 

 subfuscous, with a whitish spot below the stigma ; terebra J nearly 

 as long as the abdomen. Length, ^ 1 ; wings, 2^ : 2 1 — li 5 

 wings, 2| — 3| lin. 



Var. 1 5 . Hind coxae testaceous. Rare. 



Var. 2 2 • Second abdommal segment with a few rugosities at 

 the base. 



Antennae $ 25-jointed, nearly as long as the body. The narrow 

 testaceous border of the abdomen sometimes disappears after the 

 3d segment. The entire disk of the abdomen is alwaj^s black and 

 shining, with a few short pale hairs. Some examples have a few 

 rugosities at the base of the 2d segment, which must be regarded 

 as exceptional. Squamuhc and radices of the wings testaceous ; 

 stigma and nervures blackish. 



The (? here introduced has 28-jointed antennae, longer than the 

 body ; the 1st abdominal segment is nanowly edged with testa-
