BRITISH ICHNEUMONS. [Phygadeuon. 



said to occur on the Continent in May ; I have found both sexes in the 

 New Forest, the male near Jirockenhurst in May, 1895, and the female in 

 Lyndhurst in August, 1901 ; the female has also occurred to me on 

 bushes in the Bentley Woods, near Ipswich, in June.

Head somewhat stout ; clypeus narrow and sub-discreted, eyes glabrous ; 



$ with palpi and centre of the mandibles ferrugineous. Antennae of $ 

 black ; of ? hardly longer than half the body, filiform, twenty to twenty- 

 two jointed, with the seven basal joints, excepting sometimes the scape, 

 red or ferrugineous and the remainder infuscate. Thorax immaculate ; 

 areae complete ; areola basally contracted and apically curved ; petiolar 

 area nitidulous, concave and not discreted ; apophyses distinct and obtuse, 

 spiracles circular. Scutellum black. Abdomen obovate, slightly narrower 

 than the thorax and nitidulous ; black, with segments two and three 

 entirely red, the fourth sometimes basally, or in $ entirely red, and the 

 seventh of ? more or less whitish ; post-petiole rugosely striate, sub-linear, 

 carinate and only a little broader than the petiole ; second segment of 



$ obsoletely aciculate ; terebra shorter than the basal segment. Legs 

 with the coxae and trochanters black, sometimes in $ reddish ; the 

 anterior red, with the femora more or less broadly black basally ; hind 

 pair black, with base of the femora red in $ and centre of tibiae sometimes 

 ferrugineous in both sexes. Wings clouded ; radix and base of stigma 

 white ; tegulae infuscate or ferrugineous. Length, 3-5 mm. 



Thomson excludes Gravenhorst's $ , probably on account of its dis- 

 creted petiolar area, and makes no mention of it at all ; he might, how- 

 ever, have included var. 2, which has the legs red, with the coxae infuscate 

 and tibiae immaculate, since Taschenberg says that in both sexes the 

 petiolar area is without costae, and that it is the more typical form in 

 point of frequency. 



The female of this species is similar to P. fumaior, but the radial 

 nervure is basally clouded, the petiolar area centrally excavate, and the 

 apophyses distinct though obtuse. From P. dumeioniin the female may 

 be known by the more slender legs, the slightly longer terebra, the 

 obviously longer basal flagellar joints, and the whole body and legs are 

 less pilose. 



The brachypterous form, Pez. droniicus, is here for the first time asso- 

 ciated with Phyg. variabilis (having been, certainly erroneously, placed in 

 Hemiteles) on account of its stout antennae and the peculiar shape and 

 convexity of the abdomen. 



This species is very closely allied to P. dumeforum, but is smaller with 

 the frons much more finely though not more closely punctate, the post- 

 petiole less strongly strigose and somewhat broader, the ? antennae are
