Genus METOPSILUS*. 
Tue characters presented by several species hitherto 
associated mth the preceding group, are sufficiently 
distinct to entitle them to he ranked at least as a 
separate sub-genus. The antenn® are hut slightly 
clavate, the anterior ivings very acute at the apex, 
■with a slight sinuosity or emargination on the hinder 
margin just below the tip, which gives them a some- 
what falcate shape ; the inner margin like'wise 
deeply emarginate behind the middle. The larva 
offer several very distinctive marks, particularly that 
of having the anterior segments very much at- 
tenuated, and capable of being drawn within each 
other ; a peculiarity which has caused them, as was 
formerly noticed, to he named Chenillei Cochmnes 
by French naturalists, because the head and neck 
hear some resemblance to a pig’s snout. These 
caterpillars are not distinguished by great brilliancy 
or variety of colours, being chiefly brown and green, 
with a white lateral line extending from the anal 
horn to the third or fourth segment, and they have 
invariably two or three large eye-like spots on each 
side either of the second, third, fourth, or fifth
