A series of this species shows it to be extremely 

 variable in the intensity, and sometimes in the precise 

 form of the markings, some specimens having three 

 instead of two triangular costal spots before the apex. 

 It is nearly allied to Semasia tar and ami, Mschl., but 

 that species, which is from Labrador (Mschl.) and 

 Oregon (Fern.), differs in its much less clearly defined 

 markings, and in the absence of a clearly indicated patch, 

 this can be traced only in a dark spot on the fold 

 corresponding to the patch of umber-brown scales before 

 the central fascia, described in the present species, but 

 which in tarandana appears completely isolated instead 

 of being connected by the dark ground-colour with the 

 dorsal margin ; nevertheless, it is possible (although 

 Dr. Fernald informs me that he regards this species as 

 new) transversa may prove to be the southern form of 

 the insect described by Moschler.

 this genus, at least in the typical species, are well 

 characterized by the peculiar process of hairs, which, 

 during repose, lies concealed beneath the reflected base 

 of the anterior wings/' Westwood specified the type in
