Goniocryp/us.] BRITISH ICHNEUMONS. 3OI 



He adds that the strongly and straightly narrowed head, length of 

 cheeks, prominent eyes and elongate cly[)eus differ from all other Cryptini ; 

 the eyes hardly reach the base of the clypeus, while in 6*. tHillaior 

 their apices are level with its base and the cheeks are distinctly more 

 buccate. 



This species is, indeed, very similar to G. titillator, but its size is 

 generally smaller and the pilosity much less dense, the metathoracic 

 spiracles are oblong, the clypeus sub convex, the fourth segment entirely 

 and the first from before its centre red ; the flagellar liand may or may 

 not be present ; the intermediate femora are apically red and the $ hind 

 tarsi are usually immaculate. 



I possess examples of this species, which occurs throughout Europe, 

 captured by Sladen, at St. Margaret's Bay in August, and by Colonel 

 Yerbury, at Llanbedr in Wales, and Waterville in Ireland in July. IJradley 

 has sent it me from the Birmingham district, Davis from St. Issey in 

 Cornwall, and Beaumont has captured it at Plumstead. 



CRYPTUS, Fabricius. 



Fab. Piez. 70 (1S04) ; Thorns. O. E. v. 475. 



Head with vertex declived behind ocelli ; cheeks somewhat elongate, 

 not or hardly buccate, genal costa joining the oral a little behind base of 

 mandibles ; frons more or less excavate, clypeus apically mutic and 

 broadly rounded ; mandibles somewhat narrow, with teeth of ecjual length. 

 Antennae very thin, especially in $ ; scape compressed-ovate, excised 

 below centre, shorter than post-annellus ; flagellum of $ setaceous or 

 filiform, spiral and usually white-banded, of c? setaceous and black 

 throughout. Pronotum short ; epomiae more or less distinct ; notauli 

 extending to nearly beyond centre of mesonotum ; mesosternum with 

 lateral sulci distinct and deep, extending at least to centre ; metathorax 

 with transverse carinae approximating, petiolar area reaching beyond the 

 centre ; apophyses distinct ; spiracles linear, oval or very rarely rotund- 

 oval. Abdomen fusiform, of $ nearly linear, very finely alutaceous ; 

 basal segment dilated and deflexed apically, its spiracles far behind centre 

 and dorsal carinae distinct ; second segment with epipleurae obsolete 

 s[)iracles behind centre and some distance from lateral margin, thyridii 

 small and remote from base ; anus never white-marked ; terebra straight 

 and long, though shorter than abdomen. Legs not stout ; tibiae often 

 spinulose ; c^ with hind tarsi usually white-banded. Upper wings with 

 radial cell long, its nervure apically inflexed ; nervelet nearly always 

 distinct ; areola of normal size, with its sides always convergent above ; 

 internal cubital basally parallel with the upi)er ba.sal nervure, its fenestra 

 not elongate but remote from areolet ; discoidal cell rectangular apically 

 below, its external fenestrae large and extending beyond centre of recur- 

 rent nervure. Lower wing with nervellus intercepted below, or almost 

 in, centre. 



Of the fifty-four j^alaearctic s|)ccies of this genus enunn^raled by 

 Schmicdcknccht in 1904, only fifteen have at present been noticed in 

 Britain and, even of these, three a|)pear to rest ii|)()n somewhat doul)t(ul 

 authenticity.
