second brood iu August. They spin their cocoons on the bushes on 

 which they feed, and the fly appears in two or three weeks, the speci- 

 mens reared by him flying on the 26th of August." This worm may at 

 once be distinguished from the imported currant-worm by the absence 

 of the minute black warts that cover the body of the latter. The same 

 remedies should be used for this- worm as are recommended for the pre- 

 ceding insect. 



The Currant Spax-Worm, Eufitclna ribearia Fitcb. (Fig. 61, moth ; Fig. 62, 1, 2, 

 caterpillar; 3, pupa, from the "American Entomologist.") — Devouring the leaves ; a 

 span-worm, about an inch long, bright yellow, spotted, "being nut-black. 



Many persons, in speaking of the " currant- 

 worm," confound the caterpillar-like saw-fly larva 

 with the well-known geometer caterpillar, which 

 is a native species, and was long since described 

 by Dr. Fitch, under the name of Abraxas ribea- 

 ria. As soon as the leaves of the currant are 

 fairly expanded, late in May or early in June, the 

 young caterpillars, scarcely thicker than a horse- 

 hair, may be found eating little holes in them. Fig. 61.— Moth of Currant. 

 In about three weeks after hatching it becomes fully grown, being 

 about an inch long, and bright-yellow in color, the body being covered 

 with large, black dots. The chrys- 

 alis is shining reddish-brown, about 

 half an inch long, and may be fouud 

 late in June, either upon the 

 ground or just under the surface. 

 In two weeks after entering the 

 chrysalis state the moth may be 

 observed flying about the garden 

 or resting upon the leaves duriug 

 cloudy weather. The moth is yel- 

 low ochreous, with dark, often 

 nearly transparent, blotches on the 

 wings. It is not easily mistaken 

 for any other moth. Mr. Riley, in 

 an article on this insect in the 

 "American Entomologist," states 

 that by sprinkling powdered helle- 

 bore upon the leaves, or applying 

 a solution of eight or twelve ounces 

 to a bucketful of water, the cater- 

 l)illars will be killed. Hand-pick- 

 ing assiduously followed up, and 

 a vigorous shaking of the bushes Fig. 62.— Currant Span- Worm. (After Eiley.) 

 over a sheet or a newspaper, repeated twice a day, will keep the insect 

 within moderate bounds.

 pale green, transforming iu the earth, and with wingless females and winged males. 



Next to the apple-tree borer, which has almost cut off the apple-crop 

 of the Eastern States in certain localities, the canker-worm, always 

 local iu its distribution, is the most injurious. Originally confined, as
