I think this insect may be referred to Medicasta, though it 
presents some slight structural differences from the species on 
which the genus was founded ; its general appearance, however, is 
very similar. 
The rostrum is a little longer than the head, its basal portion 
longitudinally sulcate, the sides of the sulcation convex, clothed 
with jjale setiform scales, and ending somewhat abruptly on the 
head nearly as far back as the level of the hind margin of the eyes. 
The antennje are inserted at a distance from the front of the 
rostrum about equal to a third of its length ; their scape is less 
than half as long as the funiculus, and reaches back to about the 
middle of the eye ; the joints are proportioned much as in the 
description of Medicasta ; the scrobes are as stated in the descrip- 
tion of that genus, but hardly extend forward so far as I should 
expect. The eyes are narrowed at their lower end, but can scarcely 
be called “acuminatL” The underside is clothed rather evenly 
but not closely with pale setiform scales. The prothorax is 
densely clothed with rather pale scales, under which its surface 
appears to Ije confusedly rugulose. The fascife into which the 
scales on the elytra are collected are not very conspicuous.
