 This is the most remarkable JBelid I have seen ; it might with 

 some reason be treated as the type of a new genus, owing to the 

 following characters : — Antenme inserted unusually near to the 

 base of the rostrum, the whitish hair-lilce scales on the upper- 

 surface evenly and thinly distributed, except in the prothoracic 

 cliannel, and the remarkable structure (probably sexual) of the 

 front legs. It may be noted that the same structure (except the 

 large tooth below the base of the tibia) is feebly reproduced in 

 the four hinder legs. All the ^'estiture is really white, but the 

 variation in its density makes it appear to be of three different 

 colours, sc, snowy white on the middle of the prothorax the 

 scutellum and the sides of the sterna, less snozvy on the 

 abdomen, and still less on the elytra.

 The following table shows the relation inter se of tlie species 

 described above : — 

 A. Front femora unarmed. 



B. Elytra not callose behind the scut- 

 ellum. 

 C. Elytra not carinate. 



D. Elytra not longitudinally con- 

 cave close to the suture. 

 E. Elytra not (or scarcely) pro- 

 duced at the apex (at 

 most much less than in 

 B. scalaris, Germ.). 

 F. Elytra coarsely sculptured 

 (not less coarsely than 

 in Jj. scnlaris, Germ.),

 white stripe runs
