322 BRITISH ICHNEUMONS. \Caenocryptus. 



spiracles small and circular, situated in a longitudinal furrow. Scutellum, 

 post-scutellum, and generally two dots below latter, white. Abdomen 

 fusiform, of ? as broad as thorax ; castaneous or red, with the petiole 

 basally black ; basal segment of ? laterally straight ; post-petiole dilated 

 and sub-deflexed ; ventral segments three to seven prominent ; terebra 

 longer than half abdomen, spicula spinulose. Legs dark red ; femora 

 partly, hind tarsi and tibiae, infuscate ; front tibiae of ? dilated and 

 nearly niutic, the anterior, and in $ their femora also, internally stra- 

 mineous ; c? with anterior coxae and trochanters entirely white, ? with 

 front coxae black, white-marked, and the hind ones usually badious. 

 Wings with a central cloud ; radial nervure elongate, sub-inflexed ; radix 

 white, tegulae infuscate ; nervellus opposite and intercepted far below the 

 centre, lower wing with median nervure not strongly curved. Length, 

 6 mm. 



The colour of this species is somewhat variable in extent. 



The variety eborhms is very distinct, with the thorax diffusely and apex 

 of basal segment white. 



Probably common but overlooked in Britain. Stephens records it 

 from near London, in June, and Bignell from Cann Wood at the end 

 of September. It has been several times bred from Cef?iiostoma lotella, 

 Staint. (Marshall) ; Talaeporia pseudobotnbycella {^wlom. 1881, p. 139) ; 

 and on the Continent Ratzeburg reared his variety from a species of 

 Psyche. 



2. antennatus, Bridg. 

 Cryphis aiitemiatiis, Bridg. Trans. Ent. Soc. 1881, p. 153, pi. viii. fig. 10, ?. 



A finely and closely punctate species. Head black, slightly narrowed 

 behind the eyes. Antennae filiform, slightly incrassate towards their 

 apices. Thorax black, with notauli distinct ; metathorax with two distinct 

 transverse costae, and basal area entire and quadrate ; spiracles small and 

 circular. Scutellum black. Abdomen elongate-ovate, black, with the 

 four basal segments red, the base of the first and apex of the fourth some- 

 what infuscate ; basal segment somewhat slender, gradually dilated to 

 apex, where it is one-third broader than at base, spiracles not prominent ; 

 second quadrate, remainder transverse ; terebra two-thirds of the length of 

 the abdomen. Legs dull red, with coxae, trochanters and part of the 

 tarsi, black ; hind tibiae and apices of their femora, infuscate ; hind tarsi 

 with the three central joints white. Wings with areolet pentagonal and 

 normally broad above, emitting recurrent nervure from beyond its centre ; 

 nervelet minute ; nervellus sub-opposite and intercepted just below its 

 centre. Length, 3, 3-5, 2-5 mm. 



Bridgman says (/oc. cif.), " This insect apparently belongs to Thomson's 

 sub-genus Caejwcryptus " ; and I am by no means convinced that it is not 

 synonymous with that author's C. inflatiis (cf. Opusc. Ent. v. 497 ef xxi. 

 2361). 



Two females were taken by Bridgman at Eaton near Norwich, on 

 4th April, 1874, but he did not again meet with the species i^^/ Trans. 

 Norf. Soc. 1893, p. 614), and it appears to have been quite ignored by all 

 subsequent Continental authors.
