Thersihchiis^ BRITISH ICHNEUMONS 53 



curved, discally deplanate, with poslpctiole broad, neither laterally nor 

 dorsally aciculate, but with toveae before spiracles; second sej^ment not 

 transverse, and terebra little shorter than abdomen. Ix^gs slender and 

 dull red, with coxae, trochanters and base of femora, especially of the 

 hind ones, nigrescent; anterior tarsi mainly and hind ones apically dark. 

 Wings hyaline with the short and not very broad stigma black, its base 

 and apex paler, and tegulae rufescent; radial nervure not incrassate at 

 areolar nervure, its apical abscissa straight and double length of basal, 

 which is emitted from beyond centre of stigma, its branch subelongate, 

 but not extending to apex of wing; recurrent nervure emitted beyond 

 areolar, nervellus vertical. Length, 2.5-3.5 mm. 



The elongate terebra of the female and antennae of the male will 

 distinguish this from our other small black species. 



Said to be usually common throughout north and central Europe, 

 though apparently but little understood ; Brischke bred it in Prussia from 

 its own elliptic, grey cocoon with a flavous central girdle from larvae of 

 the British weevil Ciuthorrhynchus cyanipninis. Other Coleopterous hosts 

 are given by Gaulle as C. napt and C. piinctigcr o\\ Goureau's and (iiraud's 

 authoritv. This circumstance would seem to prove the species, as now 

 understood, distinct from th^ft (or those) of the older authors, for West- 

 wood states (Mod. Class, ii. 143) "The larva of Ophioti niodera/or, Fab., 

 destroys that of Pimpla strobilt/lat, Fab."; and in his account of 'I'he 

 Police of Nature, C. D. Wilcke shows in 1838 that Ichneumon strobilella, 

 while destroying the larvae of Phalaena strohihlla in fir cones, is itself 

 killed bv '' Ichmnmon viodemlor, another very small species of ichneumon- 

 fly" [if. The Mirror Magazine, 1838, p. 123 et Kirby and Spence), as 

 remarked by Linnaeus. \\\ Britain T. moderator is recorded from Norwich 

 in May and June by Bridgman, and I do not consider it very common, 

 though on account of its small size it is doubtless overlooked. Chatham 

 in May (Garde), Seaford (Piffard), Shere (Capron), Bt'xhill in .May 

 (Ksam) and Greenings in Mav and June (W, Saunders). I haxc invaria- 

 bly met with the male by promiscous sweeping in the first half of May, 

 about woods and roadside hedges; but the female probablv hibernates 

 for it has occurred to me so late as the 28th and 2Qth September and so 

 early as April whence it extends to June on Heracleum, reeds on the 

 coast, thistles, young sallow leaves and house-windows; it is more often 

 beaten from trees than swept from herbage ; and has been found at 

 Leiston, Southwold, P)radlev, .\sj)all Woods, Palmers Heath near Brandon, 

 Bramford, Bentlev and Monk Park Wood in Sufiblk; and at Sj)ring \'ale 

 in the Isle ot Wiijht.
