258 BRITISH ICHNEUMONS. 



From P. benicornis, it may at once be known by the colour of the 

 flagcHum and femora, the ahiiost glabrous frons, and the male's longer 

 antennae. The 9 is similar to F. infimus in size and shape, but may be 

 distinguished by its much smaller carinae and much more nitidulous frons. 



Bridgman took two females with dark mouth and front coxae, at 

 Norwich, perhaps Eaton, in July and August ; I possess a single female 

 found at Felden, in Herts., by Mr. Piffard.

Head black ; palpi, mandibles and facial orbits white ; $ has nearly the 

 whole face and the apices of the cheeks also white ; clypeus of $ entirely, 

 of 9 often centrally, white, with its apical margin sub-impressed ; frons 

 finely and closely punctate. Antennae filiform and somewhat slender ; 

 scape of $ white ; basal flagellar joints apically or entirely rufescent ; of ? 

 usually centrally white-banded. Thorax black, with pronotum and cal- 

 losities before and beneath radix white ; metanotum evenly punctate, with 

 complete upper areae, of which the areola is elongate, gradually narrowed 

 basally and sinuate apically. Scutellum white ; of $ basally, or rarely 

 entirely, black. Abdomen red or badious with first and base of second 

 segment black ; sometimes nearly entirely black ; incisures often paler ; 

 post-petiole smooth, of $ quadrate and nitidulous. Legs of $ red, with 

 anterior coxae and trochanters white, basally infuscate ; hind coxae black 

 with apex and the long, acute tooth red ; apices of hind femora and tibiae 

 and sometimes more or less of their tarsi, fuscous ; legs of $ stramineous 

 with coxae and trochanters white, the hind ones being basally black ; hind 

 femora red, their tarsi and apices of their tibiae fuscous. Radix and 

 usually tegulae white ; stigma piceous. Length, 8 mm. 



This very distinct species, which has hitherto been known by its 

 Wesmaelian name, is sufficiently well-described by Stephens ; any doubt 

 which might remain is removed by an examination of the type specimen in 

 the British Museum collection, as I have (loc. cit.) pointed out. 



Taken near London, in July, but rarely ; also, I believe, near Andover 

 (Stephens) ; captured at Horrabridge, on 3rd June (Bignell). This is 

 certainly a common species in Britain ; Essex ; Mr. Piffard has found it at 

 Felden, in Herts., and I have both beaten it from Coniferae, in the Bentley 

 Woods, in April, and found it hibernating beneath the rotten bark of a 

 fallen fir log, at Foxhall, in Suffolk, in March. On the Continent, it is 

 found in Germany, Belgium and France, but does not appear to have been 

 bred, though probably parasitic upon Tor/rices.
