B. lapponicus, Fair. — Structurally almost identical 

 ■with pratorum, but with the face wider; in the colour of the 

 pubescence, however, it differs very considerably, the hairs 

 of the vertex in both sexes, and of the face in the S , are 

 more or less yellow, there is a wide yellow band on the 

 thorax in front, and a narrow one posteriorly ; the base of 

 the abdomen is clothed with black hairs which in some 

 examples only cover the basal segment, in others also the 

 base of the second, all the other segments are clothed with 

 red ; femora and underside densely clothed with pale haii s 

 in the cf, tibiae with reddish hairs; in the ? the hairs of 

 the legs are black, except those of the tarsi, which are 

 reddish.

I have little doubt that Jonellus, pratorum, and lap- 

 ponicus are races of one species, but as they are easily 

 distinguished by the colour of their pubescence, I have not 

 thought it desirable to unite them ; the armature in the ^ 

 is so far as I can see identical in all three. 



B, pratorum, Linn, {subinterruptns, Kirh. ; BurreUanu:<, 

 Kirh.). — Head and thorax clothed with black hairs, the face 

 and vertex in the S , and a broad band across the front 

 of the thorax in both sexes yellow, the rest entirely 

 black ; face in the S and 5 decidedly narrower than in 

 Jonellus, very slightly narrower in the cf, but with the 

 cheeks distinctly longer, and the fourth joint of the antennae 

 slightly longer in proportion to the third ; abdomen in the 

 cJ clothed with yellow hairs ou the lirst and second
