fasciata&nd P. subminiata, which I have described as a Macaria (Semiothisa), 

 is an artificial one. I believe thai Semiothisa and Phasiane originated from 

 the same stock, since the generic characters of these species agree remark- 

 ably. This converging of generic characters of the lower species of allied 

 genera is seen throughout the family, and probably indeed in almost every 

 family and group of the animal kingdom. In like manner, the distinctions 

 between the two above-mentioned genera and Eubolia and Diastictis are 

 highly artificial, and I adopt them as genera simply for convenience. 11 is 

 putting nature in a straight-jackel for a temporary purpose. 



SYNOPSIS OF THE SPECIES. 



Atlantic and Rocky Mountain States. 



A. Fore wings not falcate; outer edge very oblique : 



Three parallel black lines, inner and outer not curved P. airofaseiaia. 



Tbree heavy black lines, outer very sinuous, inner curved P. orillaia. 



Fore wings acute ; no well-defined Hues ; wings much mottled P. nuliculata. 



With :i vermilion tinge ; (inter line very siutious P. snoviata. 



B. Wings subfalcate : 



a. Outer and inner lines black : 



Like snoviata, but wings more produced, with two very heavy curved lines 



(in fore wings P. mcadiata. 



b. Outer and inner lines yellow : 



Outer line bent very near the apex I'- mellistrigata. 



Outer line gently sinuous, rather near the outer edge ; a diseal ringlet P. trifasciata. 



Outer line remote from the outer edge, sinuous ; a diseal ringlet P. tin mil a. 



Pacific States. 



A. Fore wings not falcate : 



Like snoviata, tinged with vermilion P. subminiata. 



B. Fore wings subfalcate: 



Clay-yellowish, a broad inner and outer line; much speckled with gray and 



black P- irrorata. 



Like sinuate, but the brown portion of the outer line in siiuintit is yellow, and the 



line is nearer the outer edge P. neptata.
