36 Eev. T. A. Marshall's monograph of 



which has 23-jointed anteniife, and is said to be so like 

 discoidnis, Wesm., as to pass for a variety ; nor can 

 the ? ho considered 2)ellucidus, Eatz. (I.e.), the terebra 

 of which is only J — j of the abdomen, and the antennae 

 23 — 26-jointed. Both of Ratzeburg's species, however, 

 are insufficiently described. The small males are very 

 like those of discoidcus, Wesm., but the latter may be 

 known by their dusky wings ; the females are easily 

 distinguished. 



A common species, but hitherto, as it seems, over- 

 looked. Taken in the London district, Northants, York- 

 shire, Devonshire, and Wilts. I have always supposed 

 it to have some relation to willows ; and this is confirmed 

 by the breeding of a ^ by Bignell, Sept. 3rd, from a gall 

 of Hormomyia caprece, Winnertz. 



24. Bracon larvicida, Wesm. 



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

 p. 41, ? . 



Black, with pale palpi ; mandibles, lateral margins of abdominal 

 segments 1 — 2, and sometimes 3, but often the 1st only, obscm-ely 

 testaceous ; belly entirely, or at the base, and legs, testaceous ; 

 middle and hind coxte black ; 4 posterior femora, or only the hind- 

 most, more or less infuscated ; segment 2 rugulose at the base ; 

 wings subhyaline, stigma fuscous ; terebra J rather more than 

 ^ the length of the body. ? . Length, 1;^ ; wings, 2f lin. 



Antennae J 25-joinied, stout, black or fuscous, about | as long as 

 the body. On each side of the vertex is an obscure, orbital, 

 reddish spot, and a similar one below each eye, all sometiines 

 wanting. Second abdominal segment rugulose on its basal half, 

 the rest of the abdomen smooth. In one specimen the 2d segment 

 is almost entirely piceous. The pale margins of segments 2 — 3 

 are sometimes obliterated. Suturiform articulation straight. 

 Metathorax smooth, with an imperfect carina, widely interrupted 

 in tlie middle. 



Three females taken in N. and S. Devon. 



A small ? from Leicestershire, only 1 line long, which 

 1 formerly sup})Osed to be a distinct species, is probal)ly 

 only a variety of larcicida, with the 4 posterior tibiaj in- 

 fuscated at til e apex.
