British Braconidce. 39 



ceous at the sides, the rest are piceous-black without paler mar- 

 gins, but with a few scattered hairs : the hind coxae are black, the 

 others being testaceous ; the hind femora are infuscated, as in one 

 of the females. 



Described from 5 females and 1 male. Common. 

 London district, Yorkshire, Northamptonshire, Devon- 

 shire, &c. 



Bred plentifully in July by Eatzeburg from the rolled- 

 up leaves of the aspen, formed by PJti/nchites hetnleti, 

 Fab. ; by Keissig from poplar leaves rolled up by B. 

 populi, L. ; by Brischke from the galls of Nematus 

 riminalis, L. Giraud states it to be a parasite of Bala- 

 ninus pyrrhoceras, Marsh. 



Bracon vitripennis, Ratz., Ichn. d. Forst., iii., 37, is 

 closely allied, and probably exists in England. Like 

 B. discoideas, but with hyaline wings ; legs testaceous ; 

 hind coxte, and apex of hind tibiae, with their tarsi, 

 blackish. Abdomen suborbicular, lateral margins and 

 belly testaceous. Antennae <? 23-jointed. Eeared from 

 willow-galls (Weidenrosen) of Salix alba, fragilis, and 

 aurita, produced by Cecidoniyia rosaria, Loew, by 

 Brischke, according to Ratzeburg ; but not mentioned 

 by Brischke himself ; cf. Schrift. nat. Ges. Danzig, n. s. 

 V. 3, 135, 178. 



Bracon pellucidus, Ratz., lib. cit., iii., 37, ? , is another 

 kindred species, likely to be found in this country, and 

 perhaps the ? of vitripennis, Ratz. Length, 1 line ; 

 terebra ^ — ^ abdomen ; wings hyaline ; antennae 23 — 26- 

 jointed ; abdomen on each side of the base with a pale 

 pellucid spot. Legs pale, hind tibiae infuscated ; or fore 

 tibiae at the base, and the 4 posterior almost entirely 

 black. Parasitic in Psyche-ca^ses on alder-leaves, &c. 

 B. oscidator, sp. 34, infra, seems hardly to differ from 

 pellucidus, except in the colour of the wings.
