BRITISH ICHNEUMONS. 261 



Legs red ; hind femora apically black ; hind tibiae black, with a central 

 white band, their tarsi also white-banded ; anterior coxae of 6 white ; 

 radix, tegiilae, the adjacent callosities and centre of pronotuni, white. 

 Length, 5-8 mm. 



This species so closely resembles the last two described, with which 

 Gravenhorst confused it, as to need no detailed description. Therefrom 

 it is, however, abundantly distinct in its sparsely punctate frons, white 

 markings, more slender body and in the sculpture of the second segment, 

 which is not shorter than its apical breadth, alutaceo-punctate and more 

 nitidulous ; the petiolar area, too, is less concave, and the coxal tooth of 

 the 9 is distinctly smaller. 



Wesmael, in 1855, ^^^ forth seven varieties of the c^, which go to show 

 that its hind tibiae may be either centrally white with the flagellum 

 entirely black, or centrally red with the flagellum concolorous beneath ; the 

 mouth and clypeus are always white, but the face is often partly or wholly 

 black ; and in one example, he says, the scutellum bore two apical 

 pale dots. 



Common in Norfolk (Bridgman) ; IVLaldon in Essex (Fitch) ; bred from 

 E7-iogaiter lanestris in the middle of July, and captured at Bickleigh early 

 in August (Bignell) ; common at Shere (Capron) ; Felden in Herts. 

 (Piffard) ; Bungay in Suffolk in June, and several at Tostock in September 

 (Tuck) ; near Guildford in August (Butler). I have taken it in Bentley 

 Woods in September, at Chipperfield in Herts., on juniper, in August, 

 and at Gosfield in Essex in July. It is common on the Continent, but 

 has not there been bred.

Head sub-obliquely narrowed posteriorly, black ; palpi, mandibles and 

 usually the clypeus, pale ; $ with face also entirely or partially white ; 

 frons shining and obsoletely punctate. Antennae of ? basally red and 

 centrally white-banded. Thorax black, with pronotum and callosity before 

 radix white ; metanotum finely rugose with complete upper areae ; areola 

 somewhat elongate ; petiolar area centrally impressed. Abdomen black, 

 with apex of first segment more or less, the three or four following entirely, 

 and occasionally the incisures of the remainder, red ; post-petiole very 

 finely aciculate. Legs red ; apices of hind femora and tibiae, and base of 

 latter, black ; all the coxae, trochanters and tarsi pale fulvous, the S how- 

 ever has the anterior coxae and trochanters white and the base of the hind 

 coxae sometimes infuscate ; hind coxae of ? with a somewhat long, black 

 tooth. Tegulae and radix pale ; stigma ferrugineous. Length, 5-7 mm. 



Brischke's ^ , adopted by Berthoumieu, cannot belong to this species, on 

 account of its closely punctate and dull frons ; in other respects it differs 

 from P. callopus, var. b., in its immaculate face, red mandibles, the an- 

 terior trochanters being alone "gelb," and in the infuscescence of the hind 

 tarsal joints. 



This is certainly quite a common species in IJritain, as it also is in 

 central Europe, though nothing is yet ascertained regarding its economy.
