BRITISH ICHNEUMONS.

segments only red (var. /. melanopyrrhus, Ste. = sub-niger, Berth.) ; the 

 seventh segment only red (var. haei/iorrhoidalis, Grav.) ; or, indeed, the 

 whole abdomen, excepting only the petiole, may be red or ferrugineous 

 (var. atiospilus, Thoms.). In the varieties bicuspis, Kriech., secretus, Berth, 

 and anospilus, Thoms., the areolet is more or less widely open above. 



Stephens says it is not very rare, and that it has been taken in Darenth 

 AVood, in the middle of June ; and also in Devonshire, where, more 

 recently, Parfitt bred it from pupae dug up at the base of trees, though 

 I am not aware any specified British host has ever been cited. It is 

 recorded from Essex ; Wellington College, in Berks., in August ; Guestling, 

 Sussex, &c. ; and I have taken it flying to the burrows of Crabrones, in a 

 gate-post, at Ipswich, in the middle of June, and beaten it from hazel, in 

 Assington Thicks, Suffolk, at the end of May. Common throughout 

 Europe and Algeria. Bred in Austria, from Ophiusa craccae.

The females of this sub-tribe, with which Protichneumon and Coelich- 

 neumon have until quite the other day been commingled, are at once 

 distinguished by the characters already indicated ; but in the case of the 

 males the matter is less simple, as is pointed out in my notes under the
