Microcryptus?[ BRITISH ICHNEUMONS. 29 



longer and black seven basal antennal joints, of which the following five or 

 six are white, with the hind tarsi dull testaceous, becoming paler towards 

 their apices. 



I can find nothing in the description of C. leKCOfarsus to justify specific 

 rank, excepting, perhaps, (Iravenhorst's vague note that the whole body is 

 more incrassate, with the legs shorter and stouter ; Taschenljerg says the 

 hind legs are not elongate, with the femora sub-inflated ; but a specimen 

 in my collection, named by Bridgman, agrees ad amussini with M. per- 

 spicillator ; it has the clypeus and i)ronotum white, the front coxae piceous 

 and the metathorax coriaceous, with the areola hexagonal and entire, with 

 its lateral costae weak, the basal area parallel-sided, the petiolar not dis- 

 creted and the spiracles oblong. The conformation of the metathorax 

 will at once separate it from Ciyplus a/l>a/oriiis, Vill., which it very 

 strongly resembles in coloration. 



The female of this species is so remarkably like that of Cratichneumon 

 laniits {cf. Ichn. Brit. i. 68) that it is difficult to believe there is no close 

 affinity between these species. The present, however, has the mesopleural 

 sulci well defined, the antennae and legs longer, with the latter stouter and 

 the body less nitidulous. 



This is an abundant species and occurs throughout the Continent, where 

 Gravenhorst took both sexes in July and the male in May. Stephens found 

 it about London in June and in Shropshire ; Bridgman at Earlham, near 

 Norwich, in July, and he says it has been bred at Lynn from Ttacliea pini- 

 perda ; the female is recorded from the Hastings district, and I'itch 

 (Entom. 1880, p. 255) bred it from the marble galls of Cynips Kollari 7x\. 

 Maldon. Doubtless most of the British records of this species are mixed 

 among those of Crypiiis obscurus, with which Marshall incorrectly synony- 

 mized it in his Catalogue. The variety leucotarsus is mentioned from 

 London in June by Stephens, and from Essex by Harwood. I possess 

 both sexes taken by Capron at Shere, by Piffard at Felden, and by myself 

 in the Bentley Woods ; females found in the New Forest by Miss Ciiawner ; 

 males at Guestling by Bluomfield, Greenings in Surrey by Wilson Saunders 

 in May, 1872, and at Brockenhurst by myself in August. Chitty has taken 

 males at Huntingfield and Doddington, in Kent, in June ; and at Offchurch 

 in September.
