BRITISH ICHNEUMONS. I39 



coxae, and the close, fine puncturation on the outer side of the posterior 

 femora render it distinct. 



From the c^ of /. inacrocerus this species may be separated by its less 

 closely punctate cheeks, the much finer punctures of the metathorax 

 rendering it shining and not rugose, the costulae wanting, the stronger 

 puncturation of the second and third segments, the large oblique thyridii, 

 posterior tibiae more narrowly black at the apex, the second joint of the 

 trochanters and the base of the femora internally bear more flavous mark- 

 ings, and the size, moreover, is smaller. 



Holmgren says he found several females beneath moss and under bark 

 of dead trees, associating with Spilichneumon Gmve>ihors/t dnx'mg i6th to 

 24th May, 1853, in Ostro-Gothland ; and Shuckard says (Ent. Mag. 1838, 

 p. 481) it is common during hibernation in Britain. I have found the 

 females hibernating in March in tufts of Aim caespiiosn, at Brede and 

 Battle, near Hastings, and Mr. Dalglish has sent it me from Clarkston, in 

 the middle of January ; Essex. Hope sent it to Gravenhorst from Netley ; 

 Bignell has taken it at Bickleigh, in August ; Bridgman records the 

 male as common, though the female less so, in Norfolk, and there is 

 an example from Wimbledon in his collection ; Stephens, whose /. con- 

 fiisorius probably refers to the female of this species, says it is very 

 common about London, in Shropshire and Scotland, as indeed it is 

 throughout Europe. Its parasitism appears to be chiefly confined to the 

 Avctiiae, since it has been bred from Dicranura bicuspis^ Triphaena pro- 

 nuba, as well as from other undetermined Noctune, and, on the Continent, 

 from Nonagtia fiexa, and N. sparganii, Gortyna Jlavago several times, 

 Noctua belta. and CiicuUia Santonici.
