British Braconidcc. 49 



1. Phanomeris catenator, Hal. (PL L, fig. 2). 



Colastes catenator, Hal., Ent. Mag., iv., 93, ? (1836). 

 Exothcciis ahiiormis, Wesm., Nouv. Mem. Ac. Brux., 



1838, p. 74, ? . 

 ? Bracon dimidiatus, Nees, Mon., i., 108, ? . 



Black, shining ; autennte at the base, palpi, legs (and lateral 

 margins of the J abdomen narrowly) pale testaceous ; stigma 

 fuscous ; 1st abdominal segment, base of the 2d, and the suturiform 

 articulation, rugulose ; terebra ^ of the abdomen. J?. Length, 

 1^ — If ; wings, 3 — 3^ lin. 



Head and thorax smooth, shining, with whitish pubescence. 

 Antennae about 33-jointed, fuscous, testaceous at the base. Meta- 

 thorax thickly punctulate, pubescent, with some smooth spaces. 

 Abdomen oblong-ovate, somewhat pitchy-black, a little longer, but 

 hardly wider, than the thorax : segment 1 obconic, longer by about 

 one-half than its breadth at the apex, the tubercles minute, medial, 

 rugulose, with a longiti;dinal carina which is bifurcate in front : 

 the other segments shorter, slightly decreasing in length ; 2d 

 rugoso-striated at the base, the lateral and hind margins smooth ; 

 3d and following smooth, ciliated before the apex with whitish 

 hairs ; lateral margins of segments 2 — 5 testaceous in one example, 

 in another piceous ; tarsi at the apex, and hind tarsi entirely, sub- 

 fuscous ; wings hj^ahne, squamulae ferruginous, nervures paler 

 than the fuscous stigma. <? smaller ; abdomen linear, piceous in 

 the middle of the disk ; antennae 34-jointed. 



Taken by Haliday in Ireland, and by Walker in 

 England. I captured the male and 2 females at Nunton, 

 Wilts. Bred by Briscbke from Phcenusa ruhi, Zadd. 



Wesmael's description of Exothecus ahnormis agrees 

 sufficiently with the above, except that the terebra is 

 stated to be equal to about one-sixth of the abdomen. 

 There appears nevertheless little doubt that both he and 

 Haliday had the same species under observation. 

 Nothing hinders this from being Bracon dimidiatus, 

 Nees, except the colour of the abdomen, which Nees 

 states to be rufous on its apical half. The specimens 

 taken in England have the abdomen inclining to piceous, 

 and may possibly be merely a dark variety. In Euthe's 

 collection B. dimidiatus, Nees, is doubtfully identified 

 with E. ahnormis, Wesm.
