l6 BRITISH ICHNEUMONS. [Crafocryplus. 



Birmingham, in August ; Thornley in Treswell Wood, towards the end of 

 April (|)rohably after hibernation); and Capron both sexes at Shere, in 

 Surrey. I have captured tlie female in Lyndhurst in August, and Chitty 

 at Loch Awe in May. 



4. subpetiolatus, Grav. 



Cryptiis siihpetiolalus, Gr. I. E. i. Suppl. 699 ; Ste. 111. M. vii. 2S0 ; Tasch Zeits. Ges. 

 Nat. 1865, p. 73, 9 . Ciatocryptns sitbpetiolalns. Thorns. O. E. v. 525, 9 . 



Head anteriorly sub-triangular, narrowed behind the eyes ; cheeks not 

 buccate ; palpi fulvescent and the facial orbits white. Antennae slender, 

 filiform ; dark, with two of the central joints white above ; post-annellus 

 nearly thrice longer than the scape. Thorax immaculate, with the 

 mesonotum shining and not closely punctate ; mesosternal median sulcus 

 terminated posteriorly by a sub-angulated transverse line ; coxal area 

 indeterminate, spiracles contiguous with pleural costae. Scutellum black. 

 Abdomen elongate, black and dull ; post-petiole with approximate dorsal 

 carinae ; second segment elongate, the third and fourth sub quadrate, with 

 the following transverse ; terebra longer than the whole insect, with the 

 spicula red and the sheaths pilose. Legs slender and red ; hind ones 

 with the coxae and trochanters sometimes centrally infuscate, their tibiae 

 externally and tarsi nigrescent ; femora especially slender. Wings slightly 

 clouded ; radix and tegulae white ; areolet broad, with the sides parallel, 

 emitting recurrent nervure from its centre. Length, 6 mm. 



This species will easily be distinguished by the structure of its head, less 

 basally constricted petiole, the position of the metapleural spiracles, and 

 the length of the post-annellus and of the terebra, from the remainder of 

 this genus. The elongate form and ovipositor and its dull surface some- 

 what lend it the facies of a small Ephialtes. 



The specimen from which it was originally described was taken by 

 Hope, at Netley, in Shropshire, though it has subsequently been found to 

 occur throughout the northern half of Europe. Stephens records it rarely 

 from near London, in June. There is one specimen in Dr. Capron's 

 collection, probably from Shere, and another in Marshall's (in Brit. Mus.) 

 from Cornworthy, Devon, in 1889. On June 24th, 1896, I was so fortu- 

 nate as to capture an exam[)le flying to the burrows of some Cral>ro, most 

 likely C. (juad?-iniaaila/its, in a rotten post, at Bentley, in Suffolk. It has 

 never yet been bred, and this is the first hint we have regarding the nature 

 of its hosts, for probing whose burrows its elongate terebra appears admi- 

 rably adapted.
