160 THE CANADIAN ENTOMOLOGIST. 



Hind wing blackish-gray j cilia paler, with a broad darker line close 

 to base ; under side dark gray, mottled outwardly with black in middle of 

 wing; cilia preceded by a fine ochreous line. Under side fore wing 

 smoky-black, dotted with cream-white on outer half of costa. 



Three specimens: Oak Station, Allegheny Co, Penn., Sept. i, Fred. 

 Marloff; Pittsburg, Penna., Sept. 12 and 21, Carnegie Museum, Ace. 

 No. 2960, through Dr. W. G. Holland, in whose honour the species is 

 named, and to whom I am indebted for the privilege of studying and 

 identifying a large number of most interesting specimens of Micro- 

 Lepidoptera. 



Commophila contrastana, sp. nov. 



Expanse, c^ , 20 mm.; 9,21 mm. 



Head and pa^pi cream-white; antenna, basal joint white, shaded with 

 brown ; outer joints light whitish-fuscous ; thorax and patagia purplish- 

 black, with an iridescent blue and red reflection ; abdomen and legs 

 ochreous-cream, latter shaded in front with brown. 



Fore wing : Upper half and outer third cream-white ; a sharply- 

 defined band of bluish-black, with an iridescer.t reflection, as on the thorax, 

 occupies the dorsal edge of the wing. This band begins on costa, cover- 

 ing the inner sixth ; it covers the basal area, the outer edge, is outwardly 

 oblique to lower third of wing, where it curves and continues parallel to 

 dorsum; the band is slightly wider at outer end, and terminates before the 

 ocellic space. Paralleling the apex in the oiiter fourth is a shade of light 

 olivaceous-fuscous, with a cluster of leaden scales before apex, divided into 

 four lines by shining-cream strigul?e from the costa. Between middle and 

 outer third there is a quadrate spot of same shade on costa. Cilia cream- 

 white. 



Hind wing light brownish-fuscous, darker around margin; cilia whitish; 

 under side ochreouswhite. Underside fore wing light ochreous-brown ; 

 shining gray-white below fold. 



One (^ , Oak Station, Allegheny Co., Penn., May 23, Fred. Marloff; 

 one %, New Haven, Conn., June 7, A. E. Britton. 



This s])ecies is very closely allied to C. fuscodorsana, K., and may 



prove to be the eastern form of this western species. The dorsal band in 



fuscodorsana sends a spur up to end of cell at its outer end; the strigula- 



tions in apex are much darker and limited to two well-defined broader 



lines. The shade of the dorsal band is fuscous-brown.
