NEPHELINA. 131 



is a large crest on the first segment of the abdomen, and small 

 ones on those following. The fore- and hind-wings are similarly 

 marked, and the hind margins are slightly denticulated. 



The larvae are long and smooth, with a bifid hump on the 

 penultimate segment, and with sixteen legs, but the first pair 

 of pro-legs is rudimentary. The pupae are obtuse in front, and 

 conical and pointed behind, with a bluish-white or violet 

 efflorescence. 



This genus includes a considerable number of brown or fawn- 

 coloured species, with darker lines and markings. Most of the 

 species are American ; but one or two East Indian species are 

 referred to the genus.

This Moth, which is not uncommon in the United States, 

 expands rather more than two inches. It is of a light chestnut 

 brown, irrorated with darker ; and with some whitish markings 

 towards the base of the fore-wings. There is a large white or 

 bluish-white blotch towards the hind margin near the tip, and 

 another near the hinder angle of the fore-wings, and another 

 occupying the greater part of the hind margin of the hind-wings. 

 At the base of the abdomen is an ash-coloured spot. 



The larva is flesh-coloured, with interrupted festooned 

 blackish lines, with two orange spots on the back. It lives 

 on " Golden Rod," and probably on oak. The pupa is entirely 

 covered with a bluish efflorescence.
