quick and certain in its action where it touches the larva, and, liberally 

 applied, it would undoubtedly destroy the vast majority of them. 

 Where the larvae are scattered singly over the bog they usually escape 

 uotice entirely and do no appreciable damage. 



An insect common to the Cape and ~New Jersey, though much more 

 destructive on the Cape, is 



THE CRANBERRY FRUIT WORM.* 



The moth producing this pest expands rather more than half an inch, 

 has narrow fore wings, and broad, somewhat triangular, hind wings; the 

 head is broad, the eyes large and black, and the palpi project well beyond 

 the head. The color of the body and secondaries is a rather pale gray, 

 with a slight metallic glisten, more pronounced on the thorax, where 

 white metallic scales are intermixed. The fore wings are rather 

 darker gray, with a more decided metallic luster; along the costa is a 

 snowy white margin, most distinct and widest at the middle of the 

 wing, narrowing and sprinkled with gray scales at the base and apex. 

 There is a darker, transverse shade very near the base; a more distinct, 

 darker, transverse band just inside the middle, and an oblique and less 

 distinct shade from the apex to the inner margin, more diffuse near the 

 middle of the wing. Above the center of the wing, at the outer third, is 

 a rather long, paler spot, constricted at the middle, at each end of which 

 is a blackish spot. Beneath, the wings are of a uniform glistening gray 

 color, darker on the fore wings. The fringes on both wings are concol- 

 orous. This insect appears on the bogs late in June and early in July, 

 with the first appearance of berries ; it is shy, flies rapidly, and is not 

 easily captured. When and where the egg is deposited is not yet 

 known, but probably on the young berry. The young berry-worm ap- 

 pears as soon as the berries are well set, eats out the center only, and 

 then migrates to another berry. The vacated berry turns red and event- 

 ually shrivels up and drops. The larva, on entering the new berry, care- 

 fully spins up the aperture made to effect an entry with a dense web of 

 fine, white silk, so that it is sometimes difficult to see where the hole was 

 made. In this berry it becomes half-grown, and, working out, leaves a 

 jagged opening, and again enters a new berry ; the berries are by this 

 time well grown, and sometimes the larva reaches its full size in this 

 third berry. The place of entry is as carefully closed as in the previous 

 case, and soon the berry begins to show a red color, denoting to the prac- 

 tised^ eye the presence of the enemy, but to the uninitiated appearing 

 only to be nicely ripening. Where the larva does not complete its growth 

 in this berry, it migrates to another, this time not closing the port of 

 entry. The berries are by this time nearly fully grown, and about the 

 - latter part of September or the beginning of October the worms are fully 



* This is a Phycid belonging apparently to Myelois, but as only one poor and damaged specimen was 

 obtained, we cannot now properly characterize it.— C. V. R.
