Microcryptus.] BRITISH ICHNEUMONS. 47 



synonymy of this species with his Cratocryptus ofiacus, but the generic 

 characters are quite distinct, and he evidently did not know the insect, 

 which has the hind femora hardly perceptibly nigrescent apically, and 

 the pale orbits do not extend up as far as the antennae. Brischke has 

 described what he thought to be this species (Schr. Ges. Nat. Danz. 1879, 

 p. 338), but he says the hind tarsi are not white, the intermediate femora 

 are basally black, and the coloration of the central segments, which appears 

 to me a very distinct and constant character, is quite different. 



This species has not before been noticed in Britain, and does not 

 appear to have been recognized on the Continent since first described 

 in 1829. 



I took a fine specimen flying in the sunshine, in the Dentley ^Voods, 

 near Ipswich, on 4th June, 1901 ; and there are four others in Dr. Cajjron's 

 collection, probably from tlie neighbourhood of Shere, in Surrey, draven- 

 horst only knew one male, taken in June, in Hercynia.

Head black ; clypeus discreted and apically truncate-emarginate ; epis- 

 toma hardly convex ; frons smooth, sub-pubescent, its orbits immaculate ; 

 S with the facial orbits more broadly below, cheeks, clypeus, and the 

 mouth, excepting a part of the mandibles, white. Antennae of 6 with 

 the scape red beneath ; of 9 stout, filiform, hardly longer than half tiie 

 body, the scape and basal joints red at least beneath, the third not twice 

 longer than broad and the eighth to the thirteenth white. Thorax im- 

 maculate ; metathorax rugulose and, in c?, with complete areae, petiolar 

 area not reaching beyond the centre and discreted ; apophyses wanting or 

 obsolete ; spiracles circular ; areola longer than broad, hexagonal-iiuadrate ; 

 mesosternal sulci elongate, nearly entire, inflexed. Scutellum black. 

 Abdomen red, with the second segment very finely alutaceous, the fifth 

 to seventh, except their white apical margins and the base of the first, 

 black ; of 9 oblong-ovate, as broad as the thorax, with the seventh segment 

 broadly white in the centre and the post-petiole deplanate, sub-quadrate, a 

 little curved laterally, and closely punctate ; post-petiole of S elongate, 

 not laterally curved, somewhat distinctly canaliculate and finely alutaceous ; 

 terebra as long as the al)domen, reflexed. Legs, including the coxae and 

 the 9 t'lrsi, red ; of ^ with the hind tarsi, and both sexes with apices of 

 their tibiae often somewhat infuscate. Wings a little clouded and narrow ; 

 radix and tegulae white, latter in ? rufescent. Length, 5-8 mm. 



I'Vom its allies this species may be distinguished by its smooth forehead, 



finely rugulose mesopleurae, which are smooth above, the terebra which is 



nearly longer than the abdcMiien and obviously recurved ; and in the S by 



the oblong-quadrate areola, the distinct costulae which are wanting in the 



9 , and in its white-marked anus. 



This species is the type of the genus, according to Ashmead. 



[It appears probable that the Phy^adenon lacteator, (Irav., standing in 

 our lists, is no more than the ^ of the above species, the 9 of whicli con-
