The Oblique-.Banded Leaf Roller {Cacoscia rosaceana) is reported from Victoria, injuring 



the buds and young leaves of apple and other fruit trees. This moth is a member of the 



Tortricidce or leaf-rollers, so named on account of their habit of rolling up 



Leaf-Roller, the leaves or portions of them into hollow cylinders, within which they live 



and feed. The larvae commence operations as soon as the buds begin to 



expand ; when full-grown they are about three-quarters of an inch in length, of a green or 



yellowish green colour, with the head and top of the first segment brown ; there is usually a 



darker stripe along the back, and a few smooth dots on each segment, from each of which 



arises a fine short hair. 



The ravages of the larvse are often quite serious, as they check the new growth and 

 destroy the blossoms. Spraying, to be effective, requires to be done early in the season, using 

 the Paris green spray. After the cases are formed, hand-picking and crushing of these is 

 advised.

 Province, and although no specimens have been as yet positively identified as occurring on

 Apple Worm. '**'^ ^^'7 similar in appearance. Codlin moth appears in infested pears and 

 apples as a reddish white grup or worm. The larva is whitish when young, 

 but becomes pinkish or flesh coloured as it approaches full growth. When young the head is 

 blackish, but in the full grown larva it is brown, with darker markings along the sutures. 

 The shield on the back of the first segment is of the same colour as the head. The body is 

 furnished with a few very small hairs, which arise from minute elevated points, of which there 

 are eight on each segment, two on the back, each side of the middle line, and a somewhat 

 larger one above and below each spiracle. The full-grown larva is f of an inch in length. 

 The cocoon is white inside and grayish outside, usually covered somewhat with bits of 

 bark or minute fragments of whatever substance the worm happens to spin on. The enclosed 

 pupa is yellowish brown, with rows of minute teeth on the back of the abdomen. The moth 

 is grayish brown in general appearance, but examined closely, we see that the fore wings are 

 marked with alternate irregular transverse streaks of gray and brown, and that there is a 

 large rounded tawny spot on the outer hind angle. This spot is marked with streaks of 

 bronze or gold and there are similar streaks just above it. The hind wings are brown, grading 

 from light to dark from base to tip. The two sexes can be distinguished by a black pencil of
