inch. The larva is in general appearance, like that of the 

 Tortrix, and a very little smaller. The chrysalis also is 

 similar. The flight of the moth is quite rapid, and the 

 quick motion of its wings in flight give it the appearance 

 of a fly rather than that of a moth. There are but two 

 broods in the year. The first brood of larvae come from 

 the eggs laid in the preceding August, which remain on 

 the vines during the winter ; the larvae make their ap- 

 pearance soon after the removal of the water in the 

 spring. The eggs are about one-fiftieth of an inch in 

 diameter, and maybe found on the under side of the leaf. 

 From one to two weeks from the time the water is drawn 

 from the bog, the presence of the young larvae may be 

 detected by the two terminal leaves of the vine being 

 drawn together and fastened by a web. As these leaves, 

 when drawn together, expose their under or lighter sides, 

 it is readily noticed. As this occurs before the vines 

 have commenced growing, they devour the bud and then 

 the leaves, and, as they increase in size, draw together 

 several uprights of the vines, the same as the larvae of 

 the Tortrix. In a short time most of the leaves will be 

 eaten up, and little will be seen except the old, dark- 

 looking vines. After attaining their growth, they pass 

 into the chrysalis state, and the moths appear early 

 in June, two or three days before those of the Tortrix. 

 These will spread themselves over other portions of the 

 bog, seeking "pastures new" on which to deposit their 

 eggs for the second brood of larvae. This brood appears 

 in July, and continues the work of destruction up to or 

 past the middle of the month ; they then pass into the 

 chrysalis state, and are followed by the second brood of 

 moths early in August. When the eggs of these moths 

 are deposited upon the vines, their work for the year is 

 completed, and they gradually disappear, none of thein 

 surviving the winter." 

 The remedy for the " Gelechia " is to submerge the
