344 THE CANADIAN ENTOMOLOGIST. 



basal dash absent. T. a. h'ne forms a brown spot on the whitish costa 

 and two dentations below it ; the rest indistinct. Median space with a 

 dark spot in the middle of costa, running into the reniform. T. p. line 

 visible in its upper part alone, beginning with a dark spot on the white 

 costa and forming two subequal dentations, filled inwardly with black ; 

 the rest indistinct. Subreniform absent. Reniform dark gray, edged 

 with pure white. Subterminal waved line distinct, whitish, separated from 

 the t. p. line by a light brownish irregular shade. Marginal lunules very 

 small, almost wanting. Cilia uniformly gray. 



" Hind wings on the upper side black, base covered by brownish- 

 gray hairs. Cilia at apex dirty whitish, the rest dark gray. 



" Ground colour of wings on the under side black ; fasciae very 

 indistinct. 



" Fore wings : base dark grayish-black, basal fascia absent ; post- 

 medial and subapical ones visible, more or less regularly excurved ; 

 between them, at costa, a large pure white spot ; apex triangular, white, 

 suffused with isolated gray scales. Cilia white, with dark streaks from 

 extremities of veins. 



" Hind wings dark grayish-black, a little lighter at base and costa ; 

 median fascia hardly visible, highly excurved at vein 3, thus forming a 

 right-angle. Cilia light gray, with darker median stripe, at apex whitish. 



" Catocaia orba belonged to the black-winged group of the genus, 

 and resembles C. /udith, Strecker, and its variety, miranda, H. Edw., 

 but is not intimately allied to them, I believe." 



Here Prof Kusnezov gives in detail points of difference between 

 C. orba and the two named allied forms, which it does not seem necessary 

 to repeat. I would add that from a casual glance at the figures the 

 upper surface reminds one of C. Robinsonii, though smaller and with a 

 different fringe to hind wings ; and the under side is entirely different.

We desire to thank Baron Osten Sacken very heartily for sending; us
