This species may be recognized among all the variations diifercnt 

 specimens present by the white color, rarely subochreous, the base and outer 

 edge of the wing being as pale as the middle portion, and liy the pale under 

 side of the wings and its large size. 



It varies greatly in the distinctness of the lines and the degree of irrora- 

 tion. In some, the lines are diffused, and the species is rather more heavily 

 dusted than deplanaria. Guentie's description of P. mihecularia, described 

 from one male, agrees with some of my heavily-dusted specimens; and his 

 P. mamurraria, described from one male, agrees with some of my specimens. 



Larva.— The moth has been raised by Mr. W. Saunders, of London, 

 Canada, from a " brown geometric larva on the pine, the imago appearing 

 June 24th."

10 i and 4 9. — In this species, the antennae are well pectinated, but 

 the wings are rather shorter, less produced toward the apex than in P. sub- 

 atomana. Wings ochreous-ash, the head and body uniformly tawny-brown. 

 Fore wings with three l)rown lines, the innermost bent nearly at right angles 

 in the discal space. The less distinct middle line is straight, and situated 

 just within the distinct discal dot. Between this and the outer line, the wing 

 is whitish and freer than usual from the transverse brown speckles on the 

 other parts. The outer line is regularly sinuate, slightly dentate. Beyond 

 is a broad, ochreous, diffuse shade, succeeded by a brown submarginal shade, 

 disappearing in the extradiscal space, above which, /. e., in the last subco.stal 

 s|)a('e, is a large, round, consj)icuous, white spot (sometimes there are two or 

 three white spots below this). Fringe checkered with white and dark 

 liiown. Hind wings pale ashwilhin the outer line, with a slight ociircous
