to the first thoracic where there are one or two narrow sharply defined interruptions, 
also of the general color of the body and near the anterior margin of each of the tho- 
racic segments, thereby dividing the dark stripes unequally, the anterior portion being 
little wider than the interruption. Cervical shield honey yellow, uniform in color 
with the head, but rather lighter than the anal shield. A rather narrower and 
darker lateral stripe extends from the head to the anal segment, its lower margin 
being on a line with the spiracles. At the posterior extremity of this lateral stripe, 
just above and slightly forward of the anal proleg is a round, dark-brown dot from 
which originates a short, hooked bristle; just beyond this dot and extending around 
the posterior margin of the anal segment to a corresponding point on the opposite 
side and just under the slightly projecting anal extremity is a continuous row of 
four connected dots of the same dark-brown color and each producing a short, 
curved bristle, all slightly curving upward. The head is small, rather less than the 
anal segment with the mouth parts well developed and very dark brown in color, 
being smaller than the first segment in about the same proportion as the anal seg- 
ment decreases in size from the one that precedes it and the coloration and markings 
being so nearly alike, if is not an easy matter to distinguish the two at a glance. 
From the second to the ninth segment there is little variation in the size of the 
body, it being rather slender until near the time of pupation, when it increases 
somewhat in size anteriorly. 
Description of the Pupa. (Fig. 5, b.)—Length 14™™, greatest diameter 4.5™™, 
There are no teeth or spines except at tip, where, extending from near the dorsal tip 
of the last segment are two horizontal, short, robust, blunt appendages, parallel, 
but flanked on each side by a very slender, hooked appendage, exceeding in length 
the former but of a lighter color. Just beneath these, on the ventral surface, is a 
short, deep slit, the edges and vicinity of which are very dark brown. The general 
color does not differ from that of other allied species. ; 
The larvie, from which all of my adults were reared, were taken 
from corn plants either in the field, or from plants sent me by my 
correspondents, and I saw every one of them in transferring them 
to the breeding cages. All were working in corn in precisely the 
same manner and there was certainly no noticeable difference in the 
larve. The imagoes, however, were those of two species, as they are 
now understood, the larger number being the one under consideration, 
while the remainder were Hadena misera Grt. If, therefore, the two 
species are distinct, then this also must be added to the list of corn- 
destroying insects, and a further study will be necessary to separate 
the larve, whose depredations appear not to differ. Prof. Smith writes 
me that he has this last species from Colorado, taken by Bruce, and 
also from Minnesota, bred by Prof. Lugger. All this, of course, does 
not disprove the validity of the species, as, if Iremember rightly, there 
is a strong resemblance between the larvee of H. fractilinea and 
H. stipata, as I observed them in corn in Indiana some years ago. 
The various species of web worms, larve of several species of Cram- 
bus, are, of late, working nearly as much damage in our cornfields as are 
the cutworms, and are even less accessible. The larve of at least 
three species have this season devastated the cornfields of eastern 
Ohio, one of which appears to feed below ground exclusively. For 
my part, I am puzzled to know how to deal with these. Can it be done 
by breaking the sod in early summer, and allowing the wind and sun to
