ANOPLURORUM BRITANNL3S. 119 



Head sub-panduriform, vertex concave, lateral margin 

 with a deep fuscous band, interrupted at the insertion of the 

 antennae, occiput concave; antennae slender, subclavate, 

 the first joint short and thick, second long and slender, 

 third and fourth short and transverse, with a broad fuscous 

 band, fifth the largest, fuscous at the base ; trabeculae short 

 and conical ; prothorax not so wide as the head, transverse, 

 lateral margin fuscous ; metathorax transverse, sub-conical, 

 base slightly produced in the centre, posterior lateral angles 

 somewhat acute and deep fuscous ; abdomen oblong, sub- 

 claviform, with a broad deep fuscous dorsal band inter- 

 rupted at the sutures, lateral margin of the first seven 

 segments, with a fuscous deeply notched fasciae, sutural 

 margin pale; legs rather stout, with a dark spot at the 

 apex of the femora, anterior femora enlarged at the base. 

 Length f to 1. 



The first specimens of tnis species I examined, were com- 

 municated by the Rev. L. Jenyns, who took them upon a 

 Moor Harrier (Circus rufus), in which the dark dorsal 

 fascia and lateral margins are very conspicuous. In two 

 other specimens from the Common Buzzard (Buteo vul- 

 garis), in the same gentleman's collection, which I suppose 

 to be immature, the lateral margin is wanting, the dorsal 

 band less distinct. I have since received examples from 

 the Kite (Milvus ictinus), and also from the Rough-legged 

 Buzzard (Buteo lagopus), I suppose this to be the N.fuscus 

 of Nitzsch, MSS. and probably the N. discocephalus of 

 Lyonet, though it differs somewhat from his figure in the 

 prothorax.
