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; afew 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 Gn.) 
The moth expands about 13 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 
tlie 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 spet. 
This insect, lam 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 larvee 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 is long, 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-l1th), and transforms into a short, stout, reddish-brown pupa 
less than half an inch in length and rather rough and punctured. The 
pup 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
