BRITISH ICHNEUMONS. 55 



mark, black ; palpi pale ; of S sub-circular from in front, black, with palpi, 

 mandibles, labrum, clypeus, face, frontal and genal orbits, stramineous. 

 Antennae filiform, not attenuate, rufescent throughout or beneath ; first 

 flagellar joint twice longer than broad, fifth quadrate ; white-banded in both 

 sexes ; 3 also has the scape flavous below. Thorax black, pronotum and 

 humeral lines red in $ , white in 3 ; mesothorax dorsally red in $ ; meta- 

 notum scabriculous with three upper areae, of which the areola is usually 

 semi-circular. Scutellum red, somewhat strongly punctate, or (in S) tri- 

 coloured. Abdomen black, with the anterior incisures often red ; ? with 

 sixth segment usually margined, and seventh dorsally marked, with white ; 

 post-petiole scabriculous ; gastrocaeli transverse and rather deep, the inter- 

 vening space narrow and scabriculo-alutaceous ; terebra shortly exserted. 

 Legs normal ; the anterior fulvous with coxae and trochanters piceous ; 

 hind ones black, with base of tibiae, which are externally finely canaliculate 

 in $, and apex of tarsi, fulvous; anterior coxae of 6 white-marked, hind. 

 ones of $ with no scopulae. Stigma stramineous ; tegulae rufous, or in cj 

 white ; areolet coalescent above ; radius externally straight, only slightly 

 inflexed at apex. Length, 10-12 mm. 



This species may be distinguished from C. tenebrosus^ Wesm., with which 

 it was for long confused, by the ? being smaller, having the head and 

 mesonotum entirely rosy, the smaller metathoracic spiracles, larger thyridii 

 and by the absence of scopulae on the hind coxae. In the $ , the more 

 strongly nitidulous abdomen, which is never rendered dull by silky 

 pubescence, the thyridii being larger than the intervening space, will 

 render it distinct. 



Females taken at Kingussie, in coll. Cameron, named by Bridgman {cf. 

 Trans. Ent. Soc. 1881, p. 144); one by Col. Yerbury, in August, at the 

 IMound, Sutherland, in my collection (posterior legs unicolorous red). 

 Holmgren says it occurs among undergrowth throughout Sweden, not 

 infrequently, and that the male is of much rarer occurrence than the 

 female. It is also found in France, Germany and Russia, but has never 

 been bred.

? . Head croceous, not narrowed behind, nearly as broad as the thorax ; 

 face occasionally in part, and palpi, fuscous. Antennae filiform, stout, not 

 attenuate ; with the first joint generally croceous, and a white central band. 

 Mesothorax with the disc rosy ; the pronotum, an elongated humeral line, 

 and another below the tegulae, red ; the metathoracic areae are finely 

 delineated, the areola being sub-quadrate, hardly longer than broad, 

 laterally slightly curved. Scutellum and post-scutellum red. Abdomen 

 croceous or red, sometimes infuscate apically, with white marks on the 

 sixth and seventh segments ; terebra black ; the post-petiole is finely 

 coriaceous, without distinct carinae ; the gastrocaeli sub-obsolete, trans- 

 verse-linear, with the intervening space narrow. The legs are entirely 

 croceous, with the co.xae somewhat fuscous and the hind tibiae sub- 

 obsoletely canaliculate externally ; hind coxae with distinct scopulae.
