A series of this species shows it to be extremwly 
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 tarandandf 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.

of the anterior wings."" Westwood specified the type in
