244 BRITISH ICHNEUMONS, [Phyfodiaeliis. 



profuse flavidous markin<(s, in never having the scutellum laterally flavous 

 throughout as is in\ariably the case in P. po/rzotiias, from which it is best 

 distinguished by the relative length of its much less slender and always 

 darker antennae ; t\\Q<,i^ \\\ P. po/rzonias 9 are 9 mm, to the body-length 

 of 7 mm., ^ S^ mm. t(j body 7.I- mm.; in P. coryphaeus 9 tliey are only 

 75 to body 7 mm. and in J 8 to body 7^ nun. 



The present .species, and not P. polyzonias as suggested by Schmiede- 

 knecht is the common species of the genus, at least in Britain. That he 

 confused P: polyzojiias \\\Xh it is I think apparent when he says that they 

 occur in the same localities and agrees with Brischke that they are synony- 

 mous, since the latter was unable to determine to which to assign his bred 

 males from Penthina salicana, Grapholitha roboraiia, and Tortrix viridana, 

 from the last of which Bignell also records it (fjitom, 1881, p, 141), add- 

 ing (Trans, Devon, Ass. i8g8, p, 504) that it emerged towards the end of 

 July, in Devonshire, where he has also captured it at Bickleigh in May 

 and Cornwood in the middle of June. Alarquand says he has taken it in 

 the Lands End district ; Bridgman gives it as common in Norfolk and 

 bred by Atmore from Penmca hastana, Platypteryx falcida and Phlaeodes 

 tetraqiic/ra?ia ; Buckler as bred in Britain from Nocttia brunnea ; and it is 

 recorded by me from Co. Kerry in Ireland (Irish Naturalist, 1903, p. 68), 

 I have numerous examples of both the type form and my variety. The 

 former has been found by Capron about Shere in Surrey, Piifard about 

 Felden in Herts, Charbonnier at Redland near Bristol, Bloomfield at 

 Guestling near Hastings, Wilson Saunders at Greenings in Surrey, Rev. 

 F, D, Morice among heather at Brockenhurst at the end of August, 1901, 

 Whittle has bred it at Southend from aspen and probably from Clostera 

 reclusa contained therein ; and I took it at Stoke-by-Clare in Suffolk on 

 Heracleum flowers on 14th June, igoo. The variety with basally immac- 

 ulate scutellum is less common, though Capron has a full series and it has 

 been taken by Piffard at Felden and Tuck at Tostock, in Suffolk, early in 

 June; Haggart took the female abundantly on aspen leaves on nth Sep- 

 tember, 1900, at Galashiels ; and on 22nd August, 1901, I found it on 

 Angelica flowers at IMatley Bog, in the New Forest,
