268 FIFTH KKPORT OF THE ENTOMOLOGICAL COMMISSION. 
Summits of prominences yellowish, with extreme edg< b brown, spiracles yellowish 
with a Ulneeons nnnnlation. Thoracic segments with a lilaeeons line, bordered above 
with yellow immediately above the legs; segments 4 and 5 with a distinct, and the 
real of the segments each with an indistinct patch of the same two colors in aline 
with it, frequently becoming continent and forming another lint! from 10 to anal legs. 
Since this report was sent to the printer Mr. C. L. Marlatt Las pub- 
lished in the Transactions of the twentieth and twenty-first annual 
meetings of the Kansas Academy of Science (1887-'88) an account of 
the habits and transformations, with the above figures,* of this singu- 
lar Notodoutian. It appears to be double brooded, as the moths ap- 
peared in Kansas from May to June, and the females deposited their 
eggs at that time ; a second brood of moths probably appearing about 
the first of August, as the caterpillars become fully grown September 
14-21. They spin cocoons of stout, brownish silk within folded leaves 
(Fig. 106 d) or under some slight protection at the surface of the soil, 
concealed by particles of earth. 
Egg. — .9x.55 mm . Shape hemispherical, with a broad flattened base, irregularly 
encircled by a whitish cement, fastening it to the leaf. Surface shining, apparently 
smooth, but when highly magnified is found to be covered with raised lines inclosing 
minute polygonal, usually six-sided areas. Color, honey-yellow ; after hatchings 
nearly white. (Marlatt.) 
38. Seirodonta bilineata (Packard). 
This insect was known by Dr. Harris to inhabit the elm as early as 
1837, and as his descriptions were from life I reproduce them below. 
The caterpillar is found from August until October. Professor French 
has also described the larva found on the elm. (Can. Ent., xviii, 49.) 
The larva which Harris (Ent. Corr., 302) found under a sycamore and 
reared on sycamore leaves is evidently the young of Heterocampa uni- 
color; September 16 it secured itself in a leaf, doubled and fastened 
with bands of silk. 
Larva. — Body green like the following, t with a lateral white line approximating on 
the fourth, third, second, and first segments and distant on the others ; dorsal line 
and tubercles as in the following. On the sides of the sixth and ninth segments a 
triangular, claret-red spot. This caterpillar varies in having also a semi-circular red 
spot on the top of the fourth segment, and sometimes the entire back between the 
white lateral lines is claret red and augulated downwards on the sixth and ninth seg- 
ments. 
A young specimen found September 10, 1841, had the whole back deep claret red, 
bounded on each side by an irregular, whitish line. The claret color was angularly 
dilated on the sixth and ninth segments, and the tubercles on the fourth and eleventh 
segments were also deep claret red. Length, three-fourths of an inch. 
Moth. — Cinereous. Upper side of the palpi and end of the patagia dark. Fore 
wings crossed by basal and outer waved and angulated lines, margined on each side 
with blackish. The basal line is angular inwards on the internal nervure, is rounded 
outwards across to the subcostal and acutely angulated on that nervure. Outer line 
angulated outward on the internal, and waved and angulated to the costa. Between
