8 BRITISH ICHNEUMONS. [P/ectocryptus. 



and of ^ ample ; radix stramineous, tegulae black ; nervellus intercei)ted 

 far below its centre. I^ength, 8- lo mm. 



In size and conformation this species is similar to Microcryptus cto-vus, 

 but the female's black abdomen, coxae and trochanters, and stouter red 

 legs will distinguish it ; it also bears a curious superficial resemblance in 

 both sexes to Ctatidineumon anniiltitor. Fab. 



Dr. Capron (Entom. 1880, p. 88), who found it at Shere in Surrey, was 

 of opinion that C. bivinctus is not tiie true male of this s])ecies as indicated 

 by Desvignes and Marshall, and adds that he has taken an insect " which 

 is without doubt the true male." In his collection are one female and two 

 males, of which the latter are distinct inter se ; the larger certainly bears a 

 strong resemblance to P. dii^i/aius, but the metathoracic sculpture is very 

 different and the two basal segments are scabriculous. 



It is a common species in the northern and central districts of Europe, 

 though only recorded in IJritain certainly from about Hastings. I possess 

 specimens captured by Piffard at Felden in Herts., and by Miss Chawner 

 in the New Forest ; and myself took a female in the Ipswich district of 

 Suffolk in 1894. I>ignell has captured it at Ivybridge, near Plymouth, in 

 May, and Wilson Saunders, at Greenings in Surrey, in June.

^ . Head obsoletely punctate and somewhat shining, black ; mouth) 

 face and cheeks white ; clypeus discreted, with lateral foveae small. An- 

 tennae filiform, three-quarters of the length of the body, setiferous ; black, 

 with scape apically white-dotted beneath. Thorax black, sometimes with 

 white dot before the radix ; mesonotum discally punctate and deplanate, 

 with notauli basally coalesced ; metathorax coarsely scabrous, with basal 

 transverse costa only distinct laterally, the apical strongly emarginate cen- 

 trally ; sides of the transverse and apically truncate areola sub-obsolete ; 

 petiolar area flat, elongate and distinctly discreted ; metapleurae pubescent, 

 apophyses wanting, spiracles small and circular. Scutellum sub-convex, 

 black and obsoletely punctate. Abdomen narrower than thorax, black, 

 nitidulous and pubescent; segments two to six parallel-sided or gradually 

 dilated, the second or first and second with rufescent incisures, the seventh 

 usually obsoletely white-margined ; basal segment laterally slightly curved, 

 with strongly prominent spiracles, obsoletely canaliculate, uneven and 

 finely scabrous. Legs red ; the anterior with the coxae basally black and 

 apically white, trochanters white, and apices of their femora sometimes 

 flavescent ; hind coxae, trochanters, tarsi, apices of tibiae and sometimes 

 of the femora also, black ; apices of hind trochanters either red or white. 

 Wings not clouded; radix and tegulae white; nervellus antefurcal and 

 obsoletely intercepted; fenestra entire. Length, 7-9 mm. 



Gravenhorst says this little-known species is like Cryptus stomaticus, but 

 that the abdomen is shorter and broader, and the areolet more quadrate. 



1 Little doubt can remain, I think, in spite of his reference of it to Crypttis, that Wesmael's 

 description of the typical /. canaliculatiis, Grav., and more especially of its broad vertex and 

 bicarinate second segment, indicates aflBnity with the sub-petiolate Xoridini, rather than with the 

 present group.
