Mr. F. P. Pascoe on some new Genera of Curculionide. 425 
datis; corpore infra medio laste ochraceo-farinoso ; pedibus grisescenti- 
pubescentibus. Long. 43 lin. (sine rost.), ; 
Hab. Caftraria. 
PHYSARCHUS. 
Characteres fere ut in Metatyge, sed antenne ante medium rostri inserte ; 
scapo oculi medium attingente; funiculo 7-articulato, art. basali pyri- 
formi, secundo longiore, obconico, ceteris modice transversis; clava 
magna, funiculo non longiore. Elytra triangularia, antice elevato- 
truncata, humeris productis. Pedes longiores. 
This has precisely the habit of Metatyges, from which, however, it 
is strongly separated by the above characters. The eyes are, it may 
be remarked, rather more frontal, and consequently more approxi- 
mate infront. There is a sort of saccharine exudation on the speci- 
men I have selected as the type, from which the other is entirely 
free.
