though slight variations occur, there are no major differences and none 

 which would separate one group of specimens from another. 



In addition, some specimens are more gray than others, having little 

 of the red scaling that is characteristic of the species ; others possess a 

 white, rather than gray, head. 



The European ciniflonella is a gray species with very narrow wings. 

 The costa is not strikingly lighter as in most specimens of Mamathiana. 

 One or two North American specimens I have seen approach cmi-floneTla 

 very closely. The wing form appears to vary considerably due to the 

 differences in length of veins ^9 of the fore wing. In some specimens 

 these veins are considerably longer than in others, and the fore wings 

 are correspondingly longer. It is possible that what I consider Ma- 

 mathiana actually includes more than one species, or one in a state of 

 flux, but this entire group {Jdmnathiana^ sciadojm, cinifloneUa, and a 

 fourth unnamed) represents a very difficult complex of species. Only 

 careful rearing will determine the status of these.

This species is like the foregoing, kh?7iathiana, but lacks the red 

 or brown scaling of that species, is without carmine suffusion, and 

 averages smaller in size. 



Labial palpus whitish gray; second segment irrorated and suffused 

 with grayish fuscous exteriorly; third segment with broad supra- 

 medial grayish-fuscous annulus. Antenna grajdsh fuscous above, 

 whitish gray beneath. Head, thorax, and ground color of fore wing 

 whitish gray. Head lightly irrorated with grayish fuscous. Thorax 

 strongly overlaid with grayish fuscous and irrorated with black, the 

 darker colors almost obscuring the lighter ground color. Fore wing 

 suffused with grayish fuscous and irrorated with black; extreme 

 base of wing and basal half of costa whitish gray strigulated with 

 grayish fuscous and with a small black spot near base slightly inside 

 the costal edge; beyond the light costal and basal areas a strong 

 blackish to grayish fuscous shade rapidly fading to the light ground 

 color slightly beyond basal third; a similar, but smaller, dark shade 

 at middle of wing; at basal third a pair of small black discal spots, 

 one above the other, followed by white scales; sometimes these two 

 spots are confluent, forming a short, outwardly oblique black dash ; at 

 the end of cell a small white spot edged with black ; at apical fourth a
