260 BRITISH ICHNEUMONS. 



legs of ? stout, the hind coxae with a curved longitudinal crest, which 

 terminates in a stout red tooth. Stigma fuscous, radix flavous, tegulae 

 often testaceous. Length, 8--10 mm. 



The large size, dark coloration, deep gastrocaeh', short second segment 

 and the conformation of the $ coxae will serve to distinguish tiiis species. 



Mr. A. A. Dalglish has sent me an undoubted $ of this species, taken 

 early in March, at Johnstone, in Scotland, wliich, tliough bearing the 

 normal coxal tooth, has the mandibles sculptured as in Herpestomus brunni- 

 cor?iis, thus forming a distinct link between these two closely allied genera. 



Not very uncommon in gardens and woods, in June, in the metropolitan 

 district ; found also in Salop and in Norfolk (Stephens) ; Lastingham, in 

 Yorks. (Marshall) ; common, at Shere (Capron) ; Bickleigh, in Devon, in 

 September (Bignell) ; near Guildford (Butler) ; Felden, in Herts. (Piffard) ; 

 Treswell and Retford, Lines. (Thornley). I have beaten it from the 

 undergrowth in Assington Thicks and Bentley Woods, in Suffolk, in May, 

 and it almost certainly hibernates in the imago state. On the Continent 

 it is a widely distributed species, and has been bred from Torfrix viridana 

 pupae frequently ; in Britain, Butler has bred it from Hyponomeuta padella 

 and H. W. Barker from EUopia fasciaria. 



25. homochlorus, Wesm. 



Phaeogenes homochlorus, Wesm. Nouv. M^m. Ac. Biux. 1844, p. 184; Berth. Ann. 

 Soc. Fr. 1896, p. 376, 9, 



Head black ; palpi and mandibles pale red ; frons not very closely 

 punctate, shining. Antennae sub-filiform ; flagellum entirely red. Thorax 

 black, with a white callosity before the radix ; metanotum rugulose ; areola 

 elongate, basally rounded and apically sub-truncate ; costulae sub-obsolete. 

 Scutellum black. Abdomen black, with apical margin of second and third 

 segments fulvous ; post-petiole glabrous. Legs red with most of the coxae 

 and part of the femora, as well as the apices of the hind tibiae and of their 

 tarsal joints, fuscous ; hind coxae with a long and stout tooth, their femora 

 centrally impressed externally. Tegulae piceous ; radix white ; stigma 

 red. Length, 8 mm. 



This species, to which no $ has been assigned, appears to differ from 

 P. stiinulator in no pertinent particular, but the colour of the flagellum, 

 Thomson makes no mention of it, and it were, I think, better considered 

 a mere variety of the latter species, although Bridgman thought it " very 

 distinct." 



Billups first took it in Britain, at Chobham in 1882, and Piffard has 

 given me an example from Felden, in Herts., so named by Dr. Capron. 

 Berthoumieu records it from France and Belgium.
