26 BULLETIN NO. 4, DIVISION OF ENTOMOLOGY. 



been some time known to growers in New Jersey, and they have used the 

 water in this way with uniform success ; a few moths of the second 

 brood find their way on the bogs, but not in sufficient numbers to do 

 any great damage. As their habits are otherwise the same as those of 

 the Anchylopera, the remedies recommended for the latter may be as 

 well used for this insect. 



The moth is attracted by light and a fire; or, better, a torch of pitch 

 pine with a basin of tar underneath, at intervals around a bog, will at- 

 tract and destroy large numbers in the early evening, soon after dark- 

 ness fairly sets in. 



THE CRANBERRY SPAN WORM. 



(Cymatophora pampinaria (Hi.) 



The moth expands about 1£ inches, and is of a pale ash-gray color, 

 sprinkled with black scales ; the wings are produced at the apex, and 

 the margins are dentate, most distinctly so on the hind wings. The 

 fore wings are crossed by two distinct black lines; the inner, one-third 

 from base and curved inward toward the center of the wing; the outer 

 is one-third from the margin, and is curved first toward the margin and 

 then inwardly toward the base of the wing. There is a less distinct 

 and somewhat diffuse line between these lines, and there is a jagged 

 pale line between the outer black line and the margin. At the margin 

 is a distinct, scalloped black line. The hind wings are marked in much 

 the same way, except that the lines are straight. Beneath, the wings 

 are of a uniform pale gray, relieved on the anterior pair by a black dis- 

 cal spot. 



This insect, I am assured by growers, appears on the bogs twice in the 

 course of the season, once in late June or early July, and again the 

 latter part of August. The larvae appear in June and again about the 

 middle of July ; when full-grown they are rather more than an inch in 

 length, of a livid reddish gray, smooth and slender, with five pairs of 

 legs ; the anterior three pairs on the three thoracic segments, one pair 

 on the eleventh and the other on the last segment. The head is deeply 

 indented above, and the anal plate isloug, acute, and considerably pro- 

 jecting. The anterior part of the first segment is darker reddish brown, 

 and there are two dorsal rows of very fine brown spots, and a wider 

 row of a darker color at the sides ; the stigmata are deep brown. 



The second brood of these caterpillars becomes full-grown early in Au- 

 gust (8th-Ilth), and transforms into a short, stout, reddish-brown pupa 

 less than half an inch in length and rather rough and punctured. The 

 pupae are naked and are found in the sand about an inch beneath the 

 surface. They are said to transform into moths toward the end of Au- 

 gust, but how they pass the winter I was not able to ascertain. 



These insects are, I am informed, found upon the bogs at Cape Cod in 

 small numbers every year, but from their color, which resembles that of a
