Head black, with mouth, clypeus, and sometimes more or less of the 

 internal orbits of $ stramineous ; mouth and usually clypeus of $ red. 

 Antennae infuscate ; scape of S beneath flavous, of $ often entirely red ; 

 flogellum, at least basally beneath, ferrugineous. Thorax black ; meta- 

 notal areae well defined ; areola cordiform ; petiolar area discreted, cen- 

 trally trans-striate and concave. Abdomen black, with segments two to 

 four, except discally, and the apex of fifth, red ; post-petiole and following 

 segments punctulate, the former sub-aciculate in $ ; gastrocaeli wanting. 

 Legs of $ entirely red or with the femora and hind coxae in part black ; 

 of S black, with anterior tarsi, and most of the tibiae and femora flavidous, 

 the hind ones with base of femora and of tibiae rufescent. Stigma piceous ; 

 radix and tegulae stramineous, latter often fulvidous Length, 6 mm. 



From the two already described, the present species may be known by 

 its more closely and deeply punctate frons, more strongly sculptured meta- 

 thorax which bears small lateral apophyses, as well as by its colour and 

 larger size. 



Thomson thinks (loc. cit.) it to be quite possible that the true /. rufilim- 

 batus of Gravenhorst ( $ ) and the female varieties of D. erythrostoma, 

 described by Wesmael in 1S55, are referable to a species distinct from 

 D. erythrostoma, Wesm. (1844), namely, to his own D. inflexus. If this 

 prove to be the case, the insect occurring in Britain, if, indeed, it occur at 

 all, will be known as D. erythrostoma^ Wesm., since little reliance is to be 

 placed upon Stephens' old record. 



Scarce, found near London, in June (Stephens). I know of no more 

 recent records. On the Continent it is taken in France, Belgium, etc., so 

 its occurrence with us is far from improbable. Since writing the above, I 

 am told by Mr. Bignell that he has captured this species at Egloskerry, in 

 Cornwall, late in July. 



4. ruficoxatus, Gj-av. 



Ichneumon ruficoxahis, Gr. I. E. i. 597 ; Ste. 111. M. vii. 203, ? . Dicaelotus rufi-

 Wesm. Nouv. Mem. Ac. Brux. 1844, p. 176; Bui. Ac. Brux. 1848, p. 316, ?. 



Head black ; cheeks hardly buccate ; frons closely punctate ; palpi and 

 apices of mandibles rufescent; $ with facial orbits sulphureous. Antennae 

 infuscate ; flagellum often rufescent or sub-stramineous beneath basally, of 

 $ filiform ; scape of $ flavous beneath. Thorax black ; pronotum of ? 

 red, of c? with callosities before radix flavous ; metanotum dull, shortly 

 bispined ; petiolar area finely shagreened throughout, not trans-strigose 

 nor discreted. Abdomen closely and strongly punctate, black with seg- 

 ments one to three, base of fourth, and incisures of the following, 

 sanguineous-red ; apex black ; post-petiole not broad, closely punctafe-
