 edge by a marginal dusky band, not present in C. nigro-fasciata. 

 Beyond, is a row of fine, nervular, black dots ; a submarginal white 

 zigzag line, going obliquely to the apex. On the costa is a sub- 

 apical pair of black stripes, the inner of the two being oblique. The 

 hind wings are pale, with very faintly marked lines. Luteous be- 

 neath towards the apex. Two dark lines beneath, the outer one 

 consisting of dots. Discal dots distinct, abdomen dusky, with the seo;- 

 ments edged with white.

Differs in its broadly pectinated antennae, the broad, mesial, black

I have specimens from O'cak, and Caribou Island. It also occurs 

 not uncommonly at the White IMountains, where it was captured bv 

 Mr. C. A. Shurtleff", August 1-11. in Tuckerman's ravine, specimens of 

 which are in the collection of this Society. Mr. F. G. Sanborn has 

 also obtained it from Mt. Washington, New Hampshire. 



There are rubbed specimens of three other species of Cidaria 

 fro;n Labrador, too much injured for description.
