This is one of (he most common ( iconic! rid moths found in Colorado. 



It occurs in the valleys leading from the plains up among i lie foot-hills, and 



will undoubtedly be found in river-valleys on the plains away from the 



mountains. 



AsPILATES PERVAEIA Packard Plate 9, fig. 34. 



AnpUaies pervaria Pack., Fifth Rep. Peab. Acad. Sc, 62, 1873. 



6 t? and 5 9. — Smaller than A. dismnilaria Hiibn. ; antennae broadly 



pectinated, but the branches not inclined to be caught together, being stiffer; 

 palpi one-half smaller. Fore wings less pointed at apex; hind wings not 

 extending beyond tip of abdomen, while in A. dissimilaria they reach a little 

 way beyond. Cream-white (rarely snow-white), with a very slight ochreous 

 tinge. Front of head and palpi brown. Both wings either quite clear or 

 finely speckled, or with heavy, large-brown specks. A single outer, oblique, 

 brown line on primaries (sometimes wanting) fading out just before reaching 

 the costa, sometimes the wing beyond the line is shaded with brown. Discal 

 dots dark, distinct on both wings (varying in size on either pair). Beneath 

 much as above ; the single line usually reproduced. The discal dots very 

 distinct. 



Length of body, <?, 0.50-0.57, 9, 0.50; of fore wing, S, 0.60-0.70, 9, 

 0.56-0.60; expanse of wings, 1.35 inches. 



Papineau, Mo. (Riley); Texas, May 21-23; Oct. 3-Nov. 11 (Belfrage, 

 Mus. Peab. Acad. Sc.). This very variable species may be recognized by its 

 whitish-speckled wings, with a single outer brown line on primaries, the 

 wing beyond sometimes tinged with brown; also by the presence of the dark 

 discal dots. It is in sonic respects allied to the European Aspilates gilvaria. 

 It is evidently double-brooded. 



The single Missouri specimen differs from all the Texas examples in 

 being snow-white above and beneath. The oblique sub marginal line is repre- 

 sented by a few scattered dark scales, the middle of the wing being clear 

 of them, while beyond the line and on the costal edge they are quite thickly 

 scattered, as also over the hind wings, so that the whole moth is without any 

 markings except the speckles.
