312 BRITISH ICHNEUMONS. [Crypliis. 



emarginate, vertex narrow, temples excavate, eyes prominent ; of $ with 

 face, clieeks, mandilDles and nearly the whole orbits, white ; of ^ with 

 mouth ferriigineous, frontal and external orbits white. Antennae of ? 

 filiform and immaculate, of $ setaceous, with scape white beneath. 

 Thorax black and pubescent ; of $ with pronotum, lines before and 

 beneath radix and propleurae white, sometimes also mesosternum, dots 

 on metapleurae and in the petiolar area ; of $ with a dot beneath radix 

 white; metanotum finely scal)rous, with all the ? costae fine but distinct; 

 lateral areae alutaceous, with the apical margin distinct and arcuate ; 

 petiolar area entire, elongate, longitudinally strigose, basally narrow and 

 arcuate ; spiracles elongate. Scutellum black, of $ apically or entirely 

 white. Abdomen very finely alutaceous, fusiform and in $ sub-linear, 

 red, with only the basal segment black ; this latter in $ is sub-linear, 

 convex and glabrous, with prominent spiracles ; tcrebra longer than half 

 abdomen. Legs elongate, of $, distinctly pubescent, red ; coxae, tro- 

 chanters and hind tibiae, with apices of their femora, black ; $ with 

 anterior coxae and trochanters marked with, and the hind tarsi nearly 

 entirely, white. Wings hardly clouded ; areolet pentagonal, narrow and 

 nearly coalesced above ; nervelet very short, J tegulae white and radix 

 piceous. Length, 10-14 "ini. 



Thomson says the typical male of his obscurus, which is Tschek's 

 a/baforiiis, has the head with the inner and outer orbits, interrupted above, 

 confluent with the cheeks, the face, mouth, scape beneath, scutellum, 

 callosity beneath radix, tegulae, a lateral line extending to the humeri on 

 the pronotum, with its front margin and its sides in the centre, together 

 with the anterior coxae and trochanters beneath, pale flavous ; the hind 

 legs with femora only narrowly black basally, their tarsi white, with the 

 fifth joint ferrugineous and the base of the first broadly black. 



The female of this species was confused with that of C. obscurus by the 

 older authors, but is well differentiated by Tschek, who says its metanotum 

 is much more finely rugose, and that the lateral areae are broadest much 

 nearer the spiracles, with their apical margin distinct and not obscured by 

 strigosities as in the last species. Thomson has greatly confused the two 

 kinds, but the colour of their $ $ \% abundantly distinct ; that of the 

 present species has the face entirely white and the hind femora mainly 

 red, and it is, too, distinctly smaller than C. ohsmrns. 



This species has hitherto been much mixed in Britain with the pre- 

 ceding and with Alicrocryptus perspicillator^ with which it was erroneously 

 synonymized by Marshall, and many of the records there enumerated may 

 appertain to it. It has been found at Shipley Bridge, Brent ; Shaugh 

 Bridge and Bickleigh, in May, by Bignell ; Copdock in Suffolk by 

 Hocking ; Essex by Harwood ; in the New Forest by Miss Chawner ; at 

 Shere in Surrey by Capron ; Felden in Herts, by Piffard ; and I have 

 found it in June, in Wicken Fen. On 5th May, I have bred this species 

 from the pupa of Taeniocampa sp., dug by Clutten during the preceding 

 autumn at Burnley ; the cocoon of the parasite in this case was much 

 paler and less stout than that of C. obscurus. Tuck has also sent it to 

 me from the flowers of ChaeivphyUuin sylvestre^ at Tostock, near Bury 

 St. Edmund's, early in June.
