382 INSECTS INJURIOUS TO THE ORANGE. 



while the fore wings of the female have minute dark-brown 

 tufts, arranged in lines more or less distinct, running obliquely 

 across them. The wings of the male measure, when spread, 

 nearly three-quarters of an inch across ; those of the female 

 are a little larger. This leaf-roller has been found trouble- 

 some in several localities in Florida. Where it exists in such 

 abundance as to require a remedy, hand-picking should be 

 resorted to, or the trees should be syringed with powdered 

 hellebore and water, or Paris-green and water, as recom- 

 mended under No. 181. 



No. 242. The Orange-leaf Nothris. 



Nothris citrifoliella Chambers. 



In the larval form this is a cylindrical yellow caterpillar, 

 with a black head, and a black patch on the next segment. 

 It feeds upon the half-grown leaves of the new shoots of the 

 orange, fastening them together with silken threads. It also 

 frequently devours the terminal buds, and thus materially in- 

 jures the growth of the tree. When full grown, it is about 

 half an inch long, very quick in its movements, and if dis- 

 turbed lets itself down from the twig by a silken thread, by 

 means of which it is enabled to regain its former position 

 among the leaves when danger is past. 



When ready for its next change, the larva rolls up a portion 

 of a leaf, and spins within the enclosure a delicate silken 

 cocoon, in which it changes to a dark-brown chrysalis. The 

 moth is found late in August and early in September; it 

 is of a grayish ochreous color, the fore wings streaked with 

 reddish and dotted with brown, the hind wings pale gray 

 with a reddish tint. The body is ochreous, dotted with dull 

 red. 



Should this insect at any time become so abundant as to 

 require the use of remedies, those suggested for No. 241 will 

 be applicable.
