greenish-ash or yellowish-green, and is marked with a dark colored 

 dorsal and sub-dorsal line, but the latter is sometimes wanting. On 

 the dorsal line is usually a row of lozenge-shaped, dark colored or 

 brownish spots, but these are sometimes entirely obsolete ; there is 

 sometimes a yellowish or brownish line below the spiracles ; on the 

 posterior end of the last segment are two short greenish spines ; 

 the under side of the body is white, or pale greenish, with a yellow 

 line in the middle. The head is still more variable in its markings 

 than the body ; it is usually greenish or yellowish, but is sometimes 

 light-brown, and more rarely it is of a pale ash color, striped verti- 

 cally with about four brown dashes.- 



This Fruit Worm is provided with only ten legs, and I am not 

 acquainted with any other Span-worm that would be at all likely 

 to be mistaken for it. When about to pupate it crawls beneath 

 leaves or any other objects that offer it a place of concealment, and 

 forms a sort of rude cocoon by drawing several leaves around its 

 body, and fastens them with silken threads. 



The moth into which the Currant Fruit Worm is finally trans- 

 formed may frequently be seen resting upon the side of a house or 

 fence, its wings outstretched and closely appressed to the surface 

 upon which it rests. Its fore-wings expand from one-half to five- 

 eighths of an inch, are of a bluish-gray color, and the most con- 

 spicuous markings are two blue dots, one near the center of each 

 wing; a short distance outside of these dots the wings are crossed 

 by a dark colored line ; on the front or costal margin of each wing 

 are a few black dots. The hind wings are paler than the fore ones, 

 and are usually crossed near the middle by a black line. 



When these Fruit-worms appear upon the currants in destructive 

 numbers, they may be destroyed by dusting the infeste'd fruit with 

 insect powder, or with powdered white hellebore ; and it is very 

 probable that dusting lime upon them when the dew is on will also 

 destroy them. 



As these worms appear at the same time as the Imported Cur- 

 rant Worms (Nematus ventricosus, Klug), it is very probable that 

 any remedy used to destroy the latter will also destroy the Fruit 

 Worms.
