Pkygadeuon.] BRITISH ICHNEUMONS. 79 



somewhat confluently punctate, intumescent at the spiracles ; third closely 

 but not confluently punctate. Legs slender and red ; coxae and tro- 

 chanters, hind tarsi, apices of their tibiae and of more or less of their 

 femora, black. Wings somewhat clouded ; radix pale flavous, tegulae 

 infuscate or black. Length, 7 mm. 



We have no clue to the correct position of this species, but that here 

 assigned to it appears most natural, since Taschenberg tells us the clypeus 

 is apically truncate, if, indeed, it belong to the present genus as now 

 restricted at all. The distinctly punctate second and third segments 

 certainly bear analogy with those of the last-described species. The 

 synonymy of Gravenhorst's S has become somewhat involved. Most 

 features of the original description coincide with Colpognathus celerator 

 {cf. Ich. Brit. i. 278), from which the present insect differs in its distinctly 

 discreted petiolar area, etc., and the second variety is considered distinct, 

 under the name P. M<trshalli, Bridg. ; indeed there is some doubt if the 

 original of Gravenhorst's description has not been entirely evolved. 



Gravenhorst took this male on Umbelliferae^ in July and August. 

 Stephens records it from near London, in June, but all the specimens, so 

 called by British entomologists, that I have been able to examine have 

 certainly belonged to the Phaeogenini. 



? 9 . Head black and very finely alutaceous, feebly and diffusely punc- 

 tate and nitidulous ; clypeus entirely glabrous, epistoma prominent and 

 dark red ; mandibles red, apically piceous ; palpi testaceous. Antennae 

 basally red ; first flagellar joint not longer than second, nor fifth than 

 broad. Thorax red, sternum often piceous ; metathorax broad and 

 convex, petiolar area sub-vertical, its basal costa wanting, apophyses sub- 

 acuminate. Abdomen very diffusely pubescent, red, with the apex of the 

 third and the following, except the apical margins, black ; basal segment 

 short, petiole slightly, post-petiole hardly, explanate ; two basal sharply 

 aciculate, rest glabrous ; terebra as long as first segment, with dark 

 valvulae. Legs red, hind femora and tibiae apically infuscate. Wings 

 squamuliform. Length, 5 mm. 



This female is here placed for convenience ; it certainly belongs to 

 Phygadeiion rather than Hemifeks, but its association is not yet demon- 

 strated. Thomson's S differed only in sexual characters. Bignell has 

 taken this female at Whitsand Bay, early in May.

Head with the vertex not broad, cheeks short and the scrobes wanting; 

 epistoma dull and rugose ; clypeus arcuately discreted and laterally foveo- 

 late ; peristomium broad ; mandibles stout, elongate and mainly red ; 

 palpi piceous ; frons smooth and shining, with deep scattered punctures ; 

 ocelli approximate. Antennae fuscescent, inserted far below the centre of 

 the eyes ; bicoloured, basally fulvous, with the three basal flagellar joints 

 gradually decreasing in length and the first shorter than the scape. 

 Thorax smooth and shining, with the notauli sub-entire; metathorax
