202 BRITISH IGHNEUMONS. [ Diaborus 



D. lituratorius is by no means an uncommon species and has been 
somewhat frequently bred in Germany from Wematus laticrus, J. septen- 
trionalis, N. ribesti, N. salicis and N. coryli (Ratzeburg) ; larvae of Dineura 
alnt (Vollenhoven) ; larvae of Dineura rufa, Nematus pavidus, Selandria sp. 
(Brischke); and from Pristiphora conjugata (Gaulle). In Britain it is a 
widely distributed garden insect, though I have never taken it myself : 
Rare at Coombe Wood in June, about London in July and in Shropshire 
(Stephens); not common at Glanvilles Wootton (Dale) ; several on goose- 
berry bushes at Lastingham in Yorks (Marshall); Earlham in Norfolk 
(Bridgman); taken by Parfitt at Stoke Hill, Exeter, in May (Bignell). 
Examples in my collection were captured at Felden in Herts (Piffard), 

South Leverton in Lincs., in May, 1897 (Thornley), Painswick in 
Gloucester (Watkins), and several from Shere (Capron). Wilson noticed 
(Trans. Yorks Nat. Union, 1882, p. 107) that this species oviposited in 
dozens at York in 1881, upon Mematus ribest’, in which it lays its eggs 
when the host-larvae have passed their second moult. A male, correctly 
named by Fred Smith, in the British Museum is labelled as having been 
bred in England from L7ocampa ovata.
