Synojms of the Species. 



A. Wings, especially hinder pair, long, produced toward the apex, 



much as in Petrophora: 



Male antenna- heavily pectinated ; inner and outer edge of mesial band heavy and 



dark 0. muniiarla. 



Male antenna- heavily pectinated : wingB wood-colored 0. lignicoloraria. 



Male antenna- slightly pectinated ; ciliated; wings light ash; intradiscal hand 



heavy 0. abrasaria. 



Antenna- simple; wings pale ash, with flesh-colored hands; inner edge of middle 

 hand no heavier than the (inter; a subniarginal coffee-colored hand, edged 

 externally with white 0. guenieata. 



Like gueneata, but smaller, and edges of middle hand less marked ; a general llesh- 



colored tint 0. carneaia. 



Fore wings tinged with reddish ; hind wings bright red O. rubrvsuffusata. 



Smaller than the preceding; cream-white hands on fore wings, and cream-colored 



hind wings 0. lacteata.' 



B. Fore wings usually shorter, hind wings much shorter, than 



in section A: 



Antennae simple ; wings short, pale-whitish; inner edge of roseate hand heavy 



and black O. designata. 



Antenna,- pectinated; wings short; middle band blaek and heavy or rust-brown. 0. femigaria.

5 c? and 3 9. — This very variable species may be known by its heavily 

 pectinated antennae, in which respect it closely resembles O. lignicolorata. 

 The style of markings is much as in O. designala; but the fore wings are much 

 longer and more pointed than in that species. Fore wings pale whitish, with 

 the median band usually dark or reddish-brown, the inner edge of which is 

 heavy and blackish, while on the outer edge are three parallel lines, much as 

 in O. designata; the edge is angled in much the same way as in designate/,. 

 Beyond are two rows of black vcnular spots, a subapical black and oblique 

 line. There are sometimes traces of four or five lines on the hind wings. 



Length of body, <?, 0.40, 9, 0.40; fore wings, <?, 0.52, 9, 0.54-0.65; 

 expanse of wings, 1.00-1.20 inches.
