Habrocrypfus.] BRITISH ICHNEUMONS. 317 



filiform, of ? setaceous, with basal flagellar joints ferrugineous at least 

 beneath, and the first more than four times longer than broad. Thorax 

 with pronotum, a line before and a dot beneath radix, white; S also has 

 two dots beneath the hind radices, two between the front and intermediate 

 coxae, a mark on the metathorax and usually vitlae on the mesonolum, 

 white ; metathorax of 9 finely alutaceous, with basal area smoother, basal 

 costae curved, the apical indicated only by the weak apophyses, its spiracles 

 circular. Scutellum red, post scutelium white. Abdomen of S narrower 

 than, of ? as broad as, the thorax and widest at apex of the third seg- 

 ment, dull and pubescent ; of $ red, with anus not or hardly infuscate, 

 of S with segments two to five parallel-sided, red, with apical margins 

 white and the basal generally black, the remainder being black, with the 

 central red coloration becoming gradually evanescent ; basal segment 

 smooth and black, of S apically white, gradually dilated with the post- 

 petiole sub-quadrate or sub-elongate ; basal segment of ? slightly curved 

 laterally, dorsally convex and glabrous with the apical angles obtuse, and 

 the spiracles not prominent ; second segment coarsely punctate and the 

 remainder glabrous ; terebra about half the length of the abdomen. Legs 

 slender, elongate ; anterior testaceous, with the coxae and trochanters 

 black, or of ^ mainly white ; the hind ones red, with coxae and tro- 

 chanters (excepting an apical white mark in S), and usually a[)iccs of 

 femora and of tibiae, black ; hind tarsi infuscate, with the central joints 

 white in both sexes. Wings hyaline ; radix and tegulae flavescent, latter 

 in 9 sometimes infuscate. Length, 6-9 mm. 



The colour of this species is variable ; the ? orbits, a mark behind the 

 ocelli, the scutellum, post-scutellum and the second tarsal joint, are whitish- 

 flavous ; the abdomen is rufescent, with the anus not or scarcely black, 

 the first segment gradually dilated, with post-petiole sub-arcuate and its 

 dorsal carinae wanting, the second alutaceous, very finely punctate and 

 pubescent, terebra slightly longer than half abdomen ; the metathorax is 

 abruptly arcuate centrally, with obsolete apophyses ; the legs slender, with 

 tibiae sub-spinulose and the front ones not inflated ; the $ has the body 

 linear, the head, thorax and coxae profusely white-marked ; the first four 

 abdominal segments a[)ically white and sometimes discally black ; and the 

 three central joints of the hind tarsi white. From the next species it 

 differs in the white capital and thoracic markings and at most narrowly 

 infuscate ? anus, the distinctly white-margined anterior segments, and at 

 most three-jointed flagellar band of the S- 



I have no hesitation in placing C. sannio as a mere variety of the male, 

 since even Thomson was (juite unable to distinguish it by any more salient 

 characters than the less extensive colour of the thorax, of the hind femora, 

 which are nigrescent, and of the tarsal joints, of which only the third and 

 fourth are white. 



The variety sedulus appears to be an intermediate form between this 

 and the next species, with the abdomen entirely red, hind femora black, 

 and the hind tarsi not white-banded ; it is considered a distinct species by 

 Thomson, who did not know it, and who doubtfully refers it to C. uni- 

 ci/ic/i/s, which has white-banded antennae and immaculate tlujrax. 



This is an abundant species in IJrilain, and lias been recorded from 

 Eaton in July by liridgman ; Ihckleigh early in .September : and bred at 

 the end of July, from a i)U[)a in a currant leaf, by Bigncll ; Acomb Wood 

 near York, by Wilson ; bred from Depressaria nervosella by Marsiiall ;
