British Braconidce. 69 



base ; terebra as long as ^ tlie abdomen. Length, 1 — 1^ ; wings 

 2^— 3i lin. 



Shorter and stouter in proportion than any of the preceding, 

 and with fewer joints in the antennae. Those of the ? are not 

 longer than the body, 20— 24-jointed ; of the <? , longer than the 

 body, 24 — 30-jointed ; fuscous, pale at the base. Mesothoracic 

 sutures impunctate, converging to a punctate pubescent depression 

 before the scutellum. First abdominal segment hardly narrower 

 at the base, ^ longer than its apical breadth, rugulose ; segments 

 2 and 3 broadest, smooth and shining, the former more or less 

 striolated at the base, the remaining segments short, and rapidly 

 decreasing in width to the apex ; segment 2 often more or less 

 ferruginous. Legs either wholly testaceous, or the hind coxaa at 

 the base, and the 2d and 3d pahs of femora and tibiae more or 

 less, fuscous. The sexes are similar. 



Not uncommon in England ; fomid at Hastings, St. 

 Albans, Maldon. Taken byHaliday also in the Hebrides, 

 and rarely in Ireland. Bred by Bignell from Tortrix 

 viridana, L. ; the two females thus obtained had the 2d 

 segment marked with a testaceous spot. Eatzeburg 

 records the species as a parasite of Recurvaria {Icucatclla, 

 Clerck ?) living externally upon the body of the larva, a 

 fact not noticed in connection with Tortrix viridana. 

 Brischke's observation is here translated from Katz., 

 lib. cit., iii., 43 : — 



" On May 28th I found on a service-tree [Pyriis 

 domestica or aiicuparia ? ] , between leaves fastened 

 together by a web, some small caterpillars, probably of 

 leucatella or some other Tinea. One of these was being 

 sucked by three parasitic larvae, placed externally, two 

 on the 7th and one on the 9th segment. The parasites 

 were ^ line long, translucent, and orange coloured on 

 the posterior half, most likely from the copiously ab- 

 sorbed juices of the caterpillar. The latter was 5 — 6 

 lines long ; it remained motionless, although still quite 

 vigorous. On May 30th the parasites were | line long ; 

 they had changed their positions ; and now a fourth was 

 to be seen, which before had probably been sucking on 

 the under side of the caterpillar. On the 31st their 

 length had increased to 1 line, and the colour was now 

 more reddish. The caterpillar had shrunk to 4 lines in 

 length. Finally, on June 1st, when the parasites were 

 1^ lines long, and exhibited lateral rows of tubercles, 

 three of them quitted the body of the caterpillar, and
