 Head and body white, frequently light brown, probably due to stain. Head 

 usually with an evident pale patch between antennae, brownish above and in 

 front. Antennae with brown dots above. Palpi short, oblique, brown speckled, 

 usually mostly brown on sides. Legs white ; front tibiae with a large brown 

 scale tuft, tarsi with slight brown annuli at ends of joints, marked only on one 

 side; mid tibiae with two heavy brown tufts, tarsi as in fore legs; hind le.gs 

 white, in dark specimens somewhat brownish before first spurs and with brown 

 at bases of spurs. Abdomen sometimes with dorsal dots, often immaculate. 



Primaries white with variably extensive lawny brown shades, usually 

 confined to inner half but sometimes encroaching on first lobe. Costa with 

 scattered dark brown scales forming a long spot over base of cleft and two 

 dots beyond. Cleft preceded by a white area, and this by a dark brown spot 

 or dash continued obliquely to costal spot by a light brown shade. There is 

 sometimes a dark dot near middle of cell and some scattered patches of dark 

 brown irroration. Inner margin of first lobe with a brown dot before apex, 

 followed by a white pencil in the fringe. Second lobe with such a dot in 

 apex preceded by two in outer margin which mark the limits of a while area

 returned them with the note that he could see no reliable distinction 

 hetween them and Zellcr's four types of viatheivianns, in poor condi-

 species is discussed in detail under the former. The type series of 

 hilihi and norgotiiciisis Grinnell, both from S. Cal., contain numerous
