GENUS METOPSILUS*. 



THE characters presented by several species hitherto 

 associated with the preceding group, are sufficiently 

 distinct to entitle them to he ranked at least as a 

 separate sub-genus. The antennas are but slightly 

 clavate, the anterior wings 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 likewise 

 deeply emarginate behind the middle. The larvae 

 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 be named Chenilles Cochonnes 

 by French naturalists, because the head and neck 

 bear 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
