134. Pamphila Massasoit, var. Suffusa, Laurent. 

 (Page 302.) 



This form has the yellow markings of the under sur- 

 face of the hind wings almost obliterated by a suffusion 

 of dark brown, while the upper surface of the fore wings 

 is of a uniform dark brown, the light-colored margin 

 found in the normal form beiuff entirely wantino". The 

 variation is generally found among the males, but also 

 occurs sparingly in the females.

Expanse of wings from 1 to 1.25 inches. 



Male.— Uppsr Biu-fnce tawny, the fore \Yings with a 

 blackish-brown border about one-eighth inch in width. 

 The base of the wing is shaded a darker color by the 

 same dusky scales. The veins are not defined by the 

 dark color, as in Hobomoh. The tawny middle area 

 of the wing is darker and more fiery than in the 

 latter. The discal bar or dash is black and very distinct 

 and well defined, although quite small in most of the 

 specimens ; running from this obliquely towards the body 

 to the posterior margin is a broken, very faint line. The 

 hind wings are a practical reproduction of the fore wings, 

 the only difference being that the dark border encircles 

 the entire wing, but is narrower on the anterior margin, 

 and the venation is well defined.

 for about one-eighth inch, and covering only the lower
