brown bands, five of which are several times larger than the 

 others, and from four of them irregular indistinct lines cross 

 the wing. The first line is situated just beyond the inner third 

 of the wing, and is often obsolete. The second line is the 

 largest and is slightly bent once in the middle of ti*8 

 wing. There is a large brown spot parallel to the costa, 

 being situated on the angle. The third line is oblique and 

 stops before reaching the inner angle and is forked on the 

 costa, while the fourth line is a short apical diffuse irregular 

 line. The apex of the wing is dark brown, and is a little more 

 acute than usual in the genus. The length of a fore wing is .20 

 of an inch. It lays its eggs on the leaves during the month 

 of August and a new brood of larvae appear in September, 

 though they hatch mostly in the following spring, or early in 

 June, and become fully grown in July. 



The larva seen from above is much like that of Lozotaenia 

 rosaceana, but the head is a little larger in proportion to the 

 rest of the body, being as wide as the body in its thickest part. 

 The body is more hairy, while the prothorax is not dark. The 

 chrysalis is rather slender, the body being contracted at the 

 base of the abdomen, on the rings of which there are dorsal 

 rows of fine spines. 



Mr. Fish writes me that " these larvae, called the Cranberry- 

 vine worms, hatch about the first of June from eggs that have 

 remained upon the leaves of the plant all winter. They com- 

 mence to feed upon the tender growing shoots of the plant, 

 drawing the leaves -together with their web for shelter, conceal- 

 ing themselves and feeding within. Before reaching their 

 full size they, if very numerous, almost wholly destroy the 

 leaves and tender shoots, giving the whole bog a dark dry ap- 

 pearance as though a fire had been over it. This is why they 

 are in some places known as 'fire-worms/ Having reached 

 their full size they spin up among the leaves or among the 

 dead leaves upon the ground. After remaining in the pupa 

 state about ten or thirteen days the moths come out and de- 

 posit their eggs upon the leaves. 



"This year the moths were out the last of June and first of 

 July. In five or six days the eggs hatched and this second 

 brood, which is usually the most destructive, mostly changed
