of a uniform brown color except that it is lighter near the base 
than elsewhere. 
The immature larva, when about a fourth grown, is pea-green 
in general color; when about half grown, or 23 mm. long, it is 
olive-green. There are two types of the full-grown caterpillars 
(Fig. 3), one apple-green and the other velvety black, the former 
predominating. The head is pale green; the body smooth, apple- 
green, with median and dorso-lateral longitudinal lines of a deeper 
green, and two or more less conspicuous fine, wavy, whitish, 
longitudinal lines on each side of the dorso-median. The stig- 
matal line and a number of small tubercular spots and dashes on 
the dorsal surface are velvety black. The other type does not 
differ from the above excepting that the head is brown and the 
body velvety black with five wavy, whitish, longitudinal lines in 
the dorsal region. Length, 1^5 inches. 
The pupa (Fig. 4), which is formed under ground within an 
oval cocoon composed of earth and silken threads, is not unlike 
that of the commoner cutworms. It is 1/2 to 4/5 inch long, and 
shining reddish-brown. 
The egg is circular in section, about 1/50 of an inch in di¬ 
ameter, slightly flattened, ribbed longitudinally and transversely, 
and is pale greenish with a faint yellowish tint, much resembling 
the color of the new fern fronds. 
Remedies .—Arsenical poisons applied to ferns in sufficient 
strength to kill the cutworms eating them discolor the fronds, 
and are further likely to adhere to the surface in a way to make 
it somewhat dangerous to handle and use them; but poisoned baits 
distributed over the benches would probably be found as useful 
against these caterpillars as against other cutworms. Fresh pyre- 
thrum, two and a half ounces of the powder to five gallons of 
water, may be sprayed on the ferns, and light traps may be used 
at night to destroy the moths. Both have been used, indeed, with 
at least fairly satisfactory results. Nicotine preparations are said 
to be effective against the cutworms. We have made no trial of 
them in this connection. As these insecticides kill by contact, they 
should be applied in the evening, when the cutworms are exposed.
