268 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Summits of prominences yellowish, with extreme edgi s brown. Spiracles yellowish 

 with a lilaceous annulation. Thoracic segments with a lilaceous line, bordered above 

 with yellow immediately above the legs; segments 4 and 5 with a distinct, and the 

 rest of the segments each with an indistinct patch of the same two colors in a line 

 with it, frequently becoming confluent and forming another line from 10 to anal legs. 



Since this report was sent to the printer Mr. C. L. Marlatt has 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 Notodontian. 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. — .OX-SS"!"". 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 hatching, 

 nearly white. (Marlatt.) 



38. Seirodonta hilineata (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 aj>proximating on 

 the fourth, third, second, and first segments and distant on the others; dorsal line 

 aud 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 angulated 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 ou 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 



* I am indebted to Prof. E. A. Popenoe for the use of this cut. 



+ The "following" species is Notodonta (Gluphisia?) ulmi Harris MSS. PI. II, figs. 

 2 aud 3. These, however, appear to represent Lochmceiis manteo (Het. suialbicans).
