Pinipla.'] BRITISH ICHNEUMONS. 81 



^. sagax was originally bred by Hartig from Tortrix Buoliana, and sub- 

 sequently several limes from T. irsinana and T. cosmophorana in May, 

 April and at the end of March ; Brischke also records it from Tischeria 

 comphxmlla, Conchvlis posterana and Atithommms pomorum. Its Continental 

 range appears to be restricted to ( jermany, Prussia and Sweden, whence I 

 have received both sexes from Upsala. Kridgman records it (Trans. Norf. 

 Soc. 1893, p. 630), with no note of its novelty as British, from Kings Lynn, 

 in Norfolk, where it was bred from Retinia lurionana by Atmore. I pos- 

 sess six of these small males, whose arcuate front tibiae render them un- 

 mistakable (though I quite think that more than one species is mixed under 

 this character, for the length of the basal abdominal segments though all 

 longer than broad varies considerably, as also does the colour of the scape 

 and hind femora). They were all captured in the spring, between the 

 4th May and 12th June by beating spruce at Elveden, birch at Assington 

 Thicks, and sweeping in Tuddenham Fen in Suffolk ; on I\Iay-blossom at 

 Burwell in Cambs. ; and at ( Josfield in Essex. One emerged at 9 p.m. 

 on 26th April, 1907, from a quantitv of dried heads of Centaurea nigra, 

 gathered at the end of the preceeding March beneath fir-trees in my 

 garden at ^Monks' Soham. It lived till 2gth, but hid secretively among 

 the debris and did not come up to the gauze, covering the breeding-jar, 

 as did the numerous male Rracon minutator, bred from 21st to 24th April, 

 and both sexes of a Plcmmahts, bred from 2nd to 23rd I\Iay. Its host was 

 undoubtedlv Urophora xo/stiiialis, manv of which emerged during the 

 following June : unless, of course, its presence there were purely acci- 

 dental and its true association were with the overhanging conifers, in 

 which case it would surely have shown itself in the jar in the course of 

 the preceeding month. Six. Bankes has given me six other males all bred 

 together between 19th and 28th April, 1896, from the larvae of Litho- 

 colktis corvlifoliella, H.S., var. caledonii'lla, Stn., at Hesleden Dene, in 

 Durham. 1 have seen two males in Bignell's collection, from Liverpool 

 and bred from larva of Lithoatlletis trifasciella found in Cann Wood, near 

 Plvmouth, in the middle of October.

9 . Head black, transverse, shining, smooth, hardly narrowed behind the 

 eyes and, seen from in front, rotund-triangular; vertex somewhat broad and 

 separated from the impresssed frons by two emarginations ; palpi strami- 

 neous, all the orbits innnaculate. Antennae dull stramineous or ferrugi- 

 neous beneath. Thorax black, gibbulous, shining, with a stramineous 

 callosity before the radix ; pleurae subglabrous and not at all punctate in 

 the furrow before the suture ; metanotum more distinctly punctate, un- 

 equally impressed with noareae, but with two longitudinal costae ; petiolar 

 region not transversely aciculate ; spiracles circular. Scutellum black. 

 Abdomen uneven, strongly but not very closely, confluently nor regularly 

 punctate, tuberculate, double length of head and thorax and as broad 

 as the latter, badious or more or less rufescent ; basal segment black 

 and bicarinate almost to apex with the intervening space glabrous ; the 

 second longer and broader than the following, which are apically elevated,
