Phygadeuon?^ BRITISH ICHNEUMONS. 77 



chanters, tarsi and apices of tibiae, black. Wings slightly clouded ; radix 

 and tegulae of $ white ; nervellus antefurcal. Length, 6-8 mm. 



This species resembles P. flavimanus, but the capital markings, trans- 

 verse areola, obsolete apophyses and the coloration of the legs will at once 

 distinguish it. Brischke thought the $ synonymous with Cuhocephalus 

 nii::rivenfn's, Thoms., but he was certainly in error. 



By no means common with us, though widely distributed in northern 

 and central Europe. Bignell records it from Bickleigh, early in Sep- 

 tember ; and three males are said to have been bred from the pupae of 

 Spilosoma fuliginosa (cf. Proc. S. Lond. Ent. Soc. 1896, p. 82). I have 

 only seen a couple of males, taken by Ur. Capron, probaljly in the vicinity 

 of Shere, in Surrey.

Phygadeuon speculator, Gr. I. E. ii. 704 ; Tasch. Zeits. Ges. Nat. 1865, p. 26, 9 ; 

 Thoms. O. E. x. 945, i 9 . 



Head black and sub-pilose, of $ not narrowed behind the eyes ; frons 

 shining, sparsely punctate and pilose; vertex angularly emarginate; clypeus 

 discreted ; genal sulcus fine, but deeply impressed, epistoma prominent. 

 Antennae of ? exactly filiform, slightly longer than half the body, with the 

 three basal flagellar joints ferrugineous beneath ; scape of $ immaculate. 

 Thorax black; mesonotum shining, sparsely punctate and pilose; meta- 

 thorax rugose, with complete areae ; areola sub-triangular, acuminate 

 basally and, in $ , emitting the costulae from far behind its centre ; petiolar 

 area discreted, with its central area broad ; apophyses and spiracles small, 

 the latter circular. Scutellum black. Abdomen of ? ovate, sub-deplanate, 

 slightly broader than the thorax, extremely glabrous and nitidulous ; black, 

 of ? with second and third segments, excepting the sides and apex of the 

 latter, red ; basal segment very broad, post-petiole closely and regularly 

 aciculate, of $ oblong-quadrate, of 9 sub-transverse, deplanate and 

 parallel-sided ; spiracles of the second and third segments situated in the 

 not acutely inflexed epipleurae ; terebra nearly as long as the abdomen, 

 with the valvulae black. Legs normal, of ? entirely red, of $ with the 

 coxae black ; tarsal claws small and not stout. Wings small, narrow 

 and infuscate ; radix red, tegulae black or ferrugineous ; radial nervure 

 emitted from the centre of the rather broad stigma ; nervellus antefurcal. 

 Length, 5-6 mm. 



The angularly emarginate vertex, position of the radial nervure and 

 metathoracic costulae will distinguish this species from all its congeners, 

 of which it may be known further from /'. sodalis by the presence of the 

 genal sulcus, its shining and sparsely punctate frons and mesonotum, the 

 relative length of the teret)ra, and by its glabrous second abdominal 

 segment. 



This species has a wide Continental distribution, and has been found 

 by Marshall, at St. Albans (in Brit. Mus.). I possess several females, 

 taken by Stanley Kemj), in Ai)ril, 1902, at Acton and Notting Hill ; by 

 Piffard, at Felden in Herts., in the same month ; and by Charbonnier, at 

 Redland, near Bristol, in May. I have rarely seen it, at Ipswich, in May, 

 and took a single example on the window of Monks' .Soliam House, 

 Suffolk, on 31st May, 1905. It has not yet been bred.
