Honey-Producing Caterpillars. 139 
individuals happening to emerge in July, August and Sep- 
tember being irregular visitants, for which the name of 
Neglecta has been given. The females of the last form lay 
their eggs upon Actinomeris squarrosa, and the chrysalids, 
thence resulting, give Violacea the next spring. 
Larve feeding on Dogwood vary much in color from those 
that feed on the Black Snakeroot, few being white in the last 
stages, but nearly all dull-crimson or green, or a mingling of 
the two. Nevertheless, a small percentage of the larve on 
Cimicifuga racemosa are also green or crimson, though the 
most of them white. Ants do not seem to visit the larve on 
the Dogwood, and on being introduced to them in confine- 
ment treat them with indifference. On rare occasions tubes 
have been discovered in the eleventh segment, fully expanded, 
and accompanied by a pulsating movement, but no teasing 
or irritating availed to make them appear. Even severe 
pressure applied to the sides of the segment failed to force 
out any fluid. As with the fall food-plant, Actinomeris 
squarrosa, the Dogwood is neither sweet nor juicy, and it is 
possible that the larve feeding on these plants do not secrete 
the fluid. 
Eggs of this polymorphic species are round, flat at base, 
the top flattened and depressed, and have a diameter of one- 
fiftieth of an inch. Their ground-color is a delicate green, 
the entire surface being covered with a white lace-work, the 
meshes of which being mostly lozenge-shaped, with a short 
rounded process at each angle. In from four to eight days 
the egg hatches into a larva, which is scarcely one-twenty-fifth 
of an inch long, and whose upper side is rounded, the under 
being flat. On each side of the dorsal line is a row of white 
clubbed hairs, with similar ones at the base and in front of 
the second joint, making a fringe around the body. The 
head is very small, obovoid, retractile and black; the legs 
retractile, and the color a greenish-white or brownish-yellow. 
The first moult occurs in from three to five days, the larva 
having increased to twice its former length, while very little
