MEMOIKS OF THE XATIOXAL ACADEMY OF SCIENCES. 
the appearance of the Euroj^ean X flromedarim, as each abdominal segment from the first to the 
ninth bears a large, tieshy,. two-toothed hump, the tliree largest on segments 3 to 5. Thus the 
outline of tlie back is serrate, and perliaps mimics the serrate edge of the leaf of the elm on which 
it feeds. The body is greenish, with the upper half of the sides washed with white, with crimson 
spots and bands, the tip of the dorsal protuberances being also crimson. 
Mr. Marlatt does not state whether the dorsal tubercles are movable, or whether the caterpillar 
is i^rotected by mimicking the outlines or the colors of the leaves of its food’ plants. Further 
observations are needed on this point. 
Cocoon . — ^‘The cocoon is formed on the surface of the earth, and consists of loose, yielding 
silk and eartli.’’ (Riley.) Marlatt states that the caterpillars spin “cocoons of stout, brownish 
silk in folded leaves or under some slight protection at the. surface of the soil, concealed by 
particles of earth. 
Fiipa . — The body is rather thick, the cremaster very blunt, with a long, slender, acute point 
bearing very short curled seta^, and divided at the end into two minute forks. Surface of the 
body with shallow sparse pits; ou the sutures of the abdomen very finely shagreeiied. Length, 
16-18 mm. “The pupa was very active, rolling a foot or more at a time.” (Soule.) 
T am indebted to .Aliss Caroline G. Soule for the excellent colored figure of the larva on PI, XIX. 
Habits. — Mr. Marlatt has published 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 
tniusformations, with the accompanying figures, of this singular Xotodoiitian, It appears to be 
double-brooded, as the moths appeared in Kansas from May to June, and the females deposited 
their eggs at that time, a second brood of moths probably appearing about the 1st of August, 
as the caterpillars became fully grown September 11 to 21. They spin cocoons of stout, brownish 
silk within folded leaves (fig. G6d) or under some slight ])rotectiou at the surface of the soil, 
concealed by particles of earth. 
1 ouce found the larva on the elm at Providence fully growu September 3, but failed to 
describe it; it pupated September 6, and the moth appeared in May of the following year. 
We are indebtetl for the following notes ou (he larva to Professor Riley: 
Found September IS, 1869, at Bellville, ou tlie cominou eliu, a most singular caterpillar. September 26, 1869,. 
they all descended to the ground and formed their cocoons in the same corner of the breeding cage. It issued the- 
following May -I, 1870. From a larva found feeding on the elm Aiigust 26 the moth issued September 21. (Fifth 
Rep. U. S. Ent. Comm. p. 267.) 
Mr. Dyar writes that he has found the larva iu its second stage earlj^ in the summer (June) 
in its “perch.” at Keene Yalley, Essex County, X. YL 
Food 2 )Iauf. — It has not yet been found ou any other plant than the elm. 
Geograpliieal dish^ibniion . — The genus ranges through the Ajipalachian into the eastern 
portions of the Campestrian subprovince, not having yet been observed west of the great plains,

which meet over the vertex, reaching to the level of the thorax in 9, a little shorter in 5.
