Fhygadeuoti.] BRITISH ICHNEUMONS. 97 



Thorax immaculate, with the notauH short and distinct ; melathorax 

 shining and not rugose, with complete and WL-U-denned areae ; areola 

 basally rounded, petiolar area discreted and nearly parallel-sided ; 

 apophyses acute and spiracles circular. Siutellum black. Abdomen 

 hardly narrower than the thorax, ovate ; black, of ? with segments two 

 and three castaneous-red and the sixth and seventh narrowly white- 

 margined ; basal segment apically sub-rectangular, as long as the terebra ; 

 post-petiole centrally sub-canaliculate, laterally sub-aciculate, with distinct 

 and convergent dorsal carinae ; second segment glabrous, with isolated 

 jjunctures. Legs red ; hind pair with the tarsi infuscate and apices of 

 femora and of tibiae black. Wings hardly clouded ; radix flavidous, 

 tegulae infuscate, nervellus antefurcal ; radial nervure not thrice longer 

 apically than basally. Length, 5 mm. 



C.ravenhorst describes a ? variety with the legs, excepting only the 

 hind tarsi, red ; and his rjificoniis also has all the legs, excepting the upper 

 side of the hind coxae and their tarsi, red, together with the fourth segment 

 and five basal antennal joints ; the terebra, too, is slightly shorter than in 

 the type form. 



I leave C. ruficornis in the position assigned it by Taschenberg for two 

 reasons : firstly because he examined the actual (iravenhorstian types and 

 had first-hand opportunity of comparing the species ; secondly because it 

 would probably be incorrect to record it from Britain in the position of a 

 good species, since ALarshall sim[)ly followed Taschenberg's synonymy, 

 and I can find no indigenous records of this particular variety. 



From the last three small species this may be known by its strongly 

 coarctate body, broader and apically dilated petiole, the three ? basal 

 flagellar joints with the femora and tibiae red, and in the c^ by its black 

 abdomen, short antennae and post-annellus. 



Not an uncommon species on the Continent, but apparently rare with 

 us. Stephens says it used to be not common near London in June ; and 

 Bridgman records it from Earlham, near Norwich, in August. I have 

 seen but two females, both taken by Piffard at Felden in Herts. It has 

 not yet been bred.
