(Tround color whitisli, densely powdered witli bbick, thus giving the 

 insect a very bright, blue-gray appearance. Collar iind patagiae black 

 tipped, and the disc of the thorax is also blackish. Primaries with the 

 ornamentation black, the lines narrow and shari»]y defined. Basal line 

 traceable. Transverse anterior line single, broader than the others, 

 outwardly convex, but as a whole its course obliciuely inward, the line 

 being closer to the base at the inner than at the costal margin. Trans- 

 verse posterior line slender, somewhat irregular in the upper i)<)rtion 

 of its course, as a wliole inwardly oblicpie and rather feebly bisinuate. 

 Median shade broa<l, did use, darkening the space between the ordi- 

 nary spots, and lost in the dark shading in the inferior portion of 

 m<'diaii space. Th median lines are connected by a bhick bar in the 

 submedian interspace, and below this the space is blackish. Subter- 

 ininal line slender, black, only a little irregular, and as a wliole parallel 

 witli the outer margin. A dusky terminal line is preceded by a series 

 of i)ale lunules. Orbicular moderate in size, upright, oval, black 

 ringed and black centered; the intervening space gray. Iveniform 

 upright, somewhat lunate, black ringed, centered with gray. The 

 transverse anterior line is preceded, the transverse posterior and sub- 

 terminal are followed, by paler shades. A darker shading runs througii 

 the center of the subterminal space, best marked near the internal 

 margin. Secondaries white in the male, dusky in the female. IJeueath 

 gray, secondaries white. On the primaries the markings of the upper 

 side are vaguely reproduced; on the -secondaries there is an exterior 

 dark band and a discal spot. 



Expanse, 1.35 to 1.55 inches (34 to 38 mm.). 



Habitat. — Colorado ; Arizona. 



This is the brightest and prettiest of the species; easily distin- 

 guished by the clear black and white powder! ngs, which give the insect 

 a clean and neat appearance. It resembles Raphia in appearance as 

 noted in the original description, but is best placed in Benms, though 

 not far remote from Panthea.
