Limmniim'] BRITISH ICHNEUMONS. 115 



the hind trochanterellus with anterior trochanters are red or in male 

 flavous ; our form appears to more usually coincide with the var. jiini- 

 perinutti, Holmgr., the male of which is very distinct in having the third 

 and fourth segments pale-banded, the only pale marks known on the 

 abdomen of the present genus and this variety is said by Schmiedeknecht 

 to be the most prevalent Continental form though I cannot consider it 

 specifically distinct. The present is at once known from our other 

 species by the centrally white hind tibiae and pure red hind femora. 



L. albidum is recorded abroad in every month from May to September 

 on umbels, etc.; Italy, Germany, France, Hungary, Lapland, and not un- 

 common in Sweden and Belgium. It has been raised from Toiirix 

 Buoliaiia by Hartig (Jahresb. 268) and by Bernuth in September (Ratz. 

 iii. 84); from 7'. vindajia, Eiipithicia recta7igidaria and the Hymcnopter- 

 ous genus Rhynchium ((iiraud, 1877). In Britain it is recorded from 

 Goneptcryx rhamni (Entom. 1880, p. 68 ; but cf. Anilasia placida, Desv., 

 post) ; Eupifhccia ahsynihiata by Atmore (Bridg.) ; and taken by the 

 former at Kings Lynn in 1906. Bridgman says it is common in Norfolk, 

 and I possess a good many specimens of both sexes, though only one male 

 with pale abdominal bands, with three females, in Capron's Surrey 

 collection ; Tuck took it at Tostock in the autumn of i8q8 and in July, 

 1899; Charbonnier at Redland near Bristol in September; Bouskell 

 found it at Rossbeigh in Co. Kerry in June, 1902 ; and to this species is 

 referable the female I mentioned (Ichn. Brit. iii. 106) "like Omorga 

 ciasiidns," as bred by Bankes with four female Pimpla altenians in May, 

 1905, from Clepsis riisticana, Tr., in the Isle of Purbeck. It has occurred 

 to me sparingly on flowers of Dauais carota in Tuddenham Fen at the 

 end of August, at Bealings at the end of July, in l\Ionk Park Wood, on 

 reeds in the Southwold salt-marshes early in August, and at Monk's Sohani 

 hovering at whitethorn in May and on Angelica flowers in August. Miss 

 Chawner has given me a female bred at Burley in the New Forest from 

 Hvponomciiia padclla during July ; and I took males at Market Rasen in 

 Lines in 191 2 so early as i ith June.

Known from the remainder of our species, except the next one, by the 

 apically black liind femora and from the last also by the more finely 

 sculi>tured mesoj)li'urae. It was much mixed with the next species, to 

 which most of the following details probably apply, till Thomson regarded 

 them as distinct in 1887. 



France, Italy, Germany, Sweden and during March, May, June and 

 August in Belgium ; bred by Reissig from Rhodophaca suavclla (Ratz. loc. 

 ctl.) and from larvae of Pionea forficalis, Eupithccia succdituricJa and 

 from an Acronycta larva by Brischke, who says the cocoon is elliptic and 

 flavidous brown. With us it has been taken at King's Lynn by Atmore, 

 (Bridg.) and at Bickleigh in Devon on 24.th June (Hignell) ; bred from 

 Phycis bctuhUa by Fitch and Bartlett (Entom. 1883, p. 66) and from
