BRITISH ICHNEUMONS. I43 



red, coxae and basal joint of trochanters only black ; hind coxae shining, 

 centrally sparsely punctate beneath, pilose throughout, with no scopulae. 

 Wings somewhat flavescent ; stigma red ; tegulae and radix piceous ; 

 areolet pentagonal. 



(?. Dull, somewhat strongly punctate, black ; juxta-antennal orbits, line 

 beneath radix, scutellum and part of tegulae stramineous; legs, except coxae 

 and trochanters, fulvous. Head evenly and somewhat strongly punctate ; 

 clypeus apically slightly rounded and marginate, centrally depressed and 

 aciculate ; apex of mandibles and maxillary palpi, except basal joint, red ; 

 cheeks as long as base of mandibles, somewhat narrow ; inter-antennal 

 tubercle distinct. Antennae somewhat short, similar to those of ? , im- 

 maculate ; flagellar joints cylindrical, the six basal bearing oval tyloides 

 and the following thirteen distinct external longitudinal raised carinae. 

 Thorax strongly punctate, with piceous pilosity ; notauli and sternauli dis- 

 tinct ; areola, costulae and petiolar area as in ? . Scutellum white, sub- 

 glabrous with a few dark setae, not centrally depressed, only slightly 

 convex, with its basal margin black. iVbdomen dull nearly to its apex, 

 sub-cylindrical, closely punctate ; first segment and gastrocaeli as in ? , 

 with the intervening space sub-aciculate ; incisures of second and third 

 segments and the ventral fold on segments two to four obsoletely rufes- 

 cent. Legs normal ; coxae and basal joint of trochanters deeply and 

 evenly punctate, black, with piceous pilosity, apical joint of latter fulvous 

 and glabrous, ^^'ings hyaline ; stigma, radix and tegulae piceous, the last 

 anteriorly stramineous ; areolet pentagonal. Length, 17-igmm. 



The female of this fine species is similar to /. priniaforius, Forst., but 

 may be known by its smaller size and immaculate coxae, as well as by the 

 characters above described. The broad body of the ? is much like that 

 of an Amblyteles and the c? superficially somewhat resembles Ctenichnenmon 

 fossorius, Grav. 



I am indebted to Mr. J. C. Haggart, of Galashiels, for a knowledge of 

 the true male of this species, which materially differs from that ascribed to 

 it by ^Vesmael. Two males were bred, along with the female, 

 in July, 1900, from pupae of Dasychini fascelina found upon 

 Erica, at Rannoch, in June. The larva constructs but a very 

 slight cocoon of its own, though it possesses the power of closing 

 such rents as may be made in its host's pupa with a substance 

 somewhat rougher than the inner cocoon of Exeiastes and con- 

 taining fine strands. The pale parts of the imago are distinctly 

 visible in the pupa some days before its emergence ; the parasite 

 Pupa of effects its escape through a sub-regularly circular orifice at the 

 i.btiupcs.'i. capital extremity of its host's pupa, which it entirely removes. 

 Besides Britain, where I expect it is rare, it is found only in 

 Germany and Belgium.
