that point. In repose, especially when the wings are below the abdomen, so that the 

 dorsum is in profile these two tufts and the long thoracic scales form a dentate outline 

 of three prominent groups of scales. (The thoracic tuft white, the two dorsal tufts 

 dark brown.) Cilia : white shaded with light brown lines, darkest opposite the dorsal 

 patch. Underside : the pattern of the upperside is more or less faintly repeated, 

 some specimens have three small dark brown dots, one about middle of cell, one on 

 same line half way between end of cell and outer margin and the third close to the 

 anal angle. Abdomen : first abdominal segment pure white, second shaded with 

 brown, others to apex dark brown, with white scales at incisions. Underside white, 

 slightly shaded with brown. Legs white, outer joints lightly shaded with brown. Alar 

 expanse 12 to 16 mm.

Larva. — Full grown, 8 mm., extended 10.5 mm., flattened, annulated. Width 

 segments 4 to 11, 1.9 mm. ; width head i.l mm. broad, flattened, triangular, retractile 

 into 2 and 3 ; head very dark brown, almost black, shining, mouth parts paler, almost 

 square deeply cleft on top forming two well rounded lobes, shagrened ; clypeus tri- 

 angular, curving out slightly just above base, suture light brown. Antennje long, 

 pale at base, two outer segments black, joints paler, ocelli brown on darker brown 

 field. Segments 2, contracted, smoky brown. Prothoracic shield divided from head 

 by pale cream color collar, narrow, but extending down almost to spiracles, color brown 

 clouded with paler shades and edged posteriorly and laterally with black. Anal shield 

 small, concolorous, roughened but not chitinous. Thoracic feet unusually long, claws 

 dark brown, upper segments pale brown. Four pairs abdominal feet but slightly de- 

 veloped, the crochets brown, small, circle slightly flattened or oval and not open, color 

 brown. Anal feet the same. Spiracles concolorous. Dorsal setae very short and 

 minute, lateral setce moderate, head setK long, nearly equal to width of head. Tuber- 

 cular plates large and polished, giving larva a shining appearance, the dorsal tubercles 

 on 3 and 4 are like prothoracic shield, chitinous, smoky brown. 



Pupa. — Very small for size of moth ; 6 mm. long, 1.6 mm. diameter at thorax, 

 rounded and tapering gradually to anal end which terminates in two very short knobs 

 on the cremaster, each armed with a single short recurved hair. Eye caps promi- 

 nent, oblong, reaching to vertex of head, clypeal space between eyes rather narrow 

 and nearly closed just above labrum ; labial palpi narrow, tapering to a point at their 

 posterior end which is two thirds distance from vertex of head to end of wing cases ; 

 latter and thoracic feet cover sixth abdominal segment ; antennal cases terminate 

 half way between tips of wing cases and end of labial palpi. No spines or hooks on 

 dorsal region. Setiv minute. Dehiscence : upper half of labial palpi separates on 

 both sides thoracic feet cases, and remains attached to labrum, clypeus and eye caps. 

 Another long separation occurs on each side between antennal cases and wing covers, 

 also a split along dorsal line which extends to posterior edge of thorax. 



About the latter part of June, 1901, when examining the tree trunks 

 at Anglesea, N. J., for small moths, I found a very interesting larval case 

 a little more than an eighth of an inch long roughly shaped like a flat-
