BRITISH ICHNEUMONS. 25I 



towards end of July (Bignell) ; Guestling, near Hastings (Bloomfield) ; 

 Greenings, near Reigate, in May (W, Saunders). Certainly a common 

 species in Britain. Piffard has captured it, at Felden, in Herts., and Tuck 

 several times, at Tostock, in Suffolk. It is very widely distributed on the 

 Continent, where it has been bred from Tortrix rosana and Etichromia 

 rufana.

This species so closely resembles the last, that a detailed description 

 were entirely superfluous ; it differs therefrom in having the head broader 

 than the thorax, that of the $ being distinctly dilated behind the eyes ; 

 cheeks not buccate and scarcely at all dilated below the mandibles ; the 

 fifth abdominal segment is black ; the legs are paler, with the coxal tooth 

 of the ? much smaller. Length, 6-8 mm. 



The mesopectoral acetabulae are a little emarginate, and its medial 

 sulcus is entire. 



Lastingham, in Yorks. (Marshall) ; Brundall, in August (Bridgman) ; 

 Guestling, near Hastings (Bloomfield). Probably much mixed with the 

 last species in Britain, and not uncommon with us, as upon the Continent.

Very like the two preceding species. Apical margin of clypeus usually 

 with a fine elevated carina ; $ with seventh flagellar joint quadrate, and 

 scape and four basal flagellar joints red, with eight to eleven white ; $ 

 with first flagellar joint shorter than second ; segments two to four and 

 whole or apex of the first red, incisures of following often rufescent ; post- 

 petiole slightly convex, shining and alutaceous ; all the coxae and tro- 

 chanters red, excepting the nearly vertical and apically truncate coxal tooth 

 of the ? , and sometimes the upper side in the $ , which are black ; 

 tegulae usually red. Length, 7 mm. 



From /". seniivitlpinus it may be known by the head being broader than 

 the thorax, with its cheeks not buccate and hardly dilated below the man- 

 dibles, and from P. planifrotis by its acetabulae not being emarginate and 

 the medial sulcus evanescent or wanting. 



Taken at Coombe and Darenth Wood, in June and July (Stephens) ; 

 Isle of Man (Walker) ; Plym Bridge, early in August (Bignell) ; Alaldon, 

 in Essex (Fitch). Another common species, taken by sweeping, in 

 meadows, near woods ; Mr. E. A. Butler has taken it, near Dorking, in 

 August ; Mr. B. Tomlin at Carlisle also in August ; I have beaten it from 

 oak, at the end of May; and swept it, at dusk, early in October, in Bentley
