the chrysalis during the winter, and emerge in the following June. They 

 spin a slight cocoon between the leaves or on the ground. They are very 

 easily raised, and require little feeding, eating much less than cg/e. The 

 moth appears here from the middle of June to about the middle of July, 

 and again the latter part of August. 



I am indebted to Dr. Lintner, of the State Museum at Albany, to 

 whom I mailed specimens of the larvre and pupse, for the following 

 scientific description. The Dr. states that these specimens were not in 

 the best condition for the purpo;;e, '• having lost many of their hairs from 

 rolling," but on comparing his description with larvae fresh from the plant, 

 it seems to me perfectly correct. 



LARV.E OF EUCHAETES COLLARIS. 



Sub-cylindrical, tapering moderately at the extremities. Head nearly 

 as large as the first segment, pale luteous with black ocelli ; body pale 

 bluish white, semi-transparent ; the pro-leg bearing segments with twelve 

 rows of tubercles, from which radiate pearl-gray branching hairs varying 

 from sparsely sub-spinose to thickly branched, which dorsally are about 

 the length of the diameter of the body, except on the last three segments, 

 where are some twice as long ; the lateral hairs are shorter, but perhaps 

 from attrition ; the longer hairs tend to unite at their tips in pencils of a 

 slaty hue. The tubercles, in their location on the segments referred to, 

 alternate between their anterior fourth and posterior third ; the sub-dorsal 

 ones are oval, the lateral ones elliptical, the latero-stigmatal sub-rotund, as 

 are also the much smaller stigmatal ones ; the form of those of the two 

 inferior rows is not evident. The stigmata are small, narrowly elliptical, 

 white, annulated with black. The legs are unicolorous with the body, the 

 terminal pair quite projected backward. 



Length of the larva at rest, .87 inch ; in motion, 1.12 inch. Diameter 

 at broadest part, . 1 6 inch. 



The cocoons are slight, consisting almost wholly of the hairs of the 

 larva, closely investing the pupa, their length from one-half to five-eighths 

 of an inch, with a diameter of about one-fourth of an inch. 



The pupne are black, closely punctated, ovoid, the terminal segments 

 blunt and unarmed, the thoracic portion projected over the wing-bases in 

 a sub-quadrate form.
