the mass of specialized scales is large, in yavapai the tufting is 

 reduced to a mere fringe of long hair, and there are no specialized 

 scales at all. I have only 3 males of yavapai, but all these had the 

 legs perfect, so that I could verify the point; of edusina I have a 

 large series of males, and even the darkest of them which most 

 resemble the new form have the femoral mass of scales conspicuous. 



In male genitalic characters yavapai differs only in details from 

 edusina; the differences are obvious enough on comparison, but not 

 so marked as might be anticipated from the difference in the sec- 

 ondary characters; the type is identical. 



In the female the differences from edusina are greater. There is 

 a series of chitinous plates surrounding the genital opening; but the 

 plates are much larger, very characteristic in form, and utterly unlike 

 those found in edusina. A comparison of the figures will make this 

 matter very clear at first glance, and that these differences are con- 

 stant I have verified by an examination of two preparations of 

 yavapai and of several edusina.

Ranges in ground color from dirty yellow- to light chocolate-brown, 

 more or less powdered and strigillate with darker brown. Head 

 concolorous; collar with an obscure darker line; thorax with vague 

 dusky transverse shadings. Abdominal tuftings small, and in well 

 preserved examples white-tipped. Primaries with basal space usually 

 a little darker; t. a. line indicated chiefly by the difference in shade 

 between the two spaces. T. p. line lost. S. t. line yellow or pale, 

 continuous or broken, sometimes preceded and sometimes followed 

 by a dark shading or an edging of black scales, in direction oblique 

 from costa to inner margin, almost rectangularly exserted on vein 

 4; the angle sometimes well marked, sometimes rounded. Orbicular 

 punctiform, black, distinct in all my specimens. Reniform moderate, 

 not well defined, upright, dusky or blackish, more or less edged or 

 marked with paler scales. The terminal area is usually paler than 

 the rest of the wing, but may be concolorous or even darker. A 

 crenulated terminal line in some examples, with a series of black 

 joints at the inward teeth. Secondaries may be lighter or darker 

 than or concolorous with primaries, with a variably distinct outer 

 line that continues the s. t. of primaries and is very much like it in 

 its make-up and variation. As a rule it does not reach the costal 

 margin and sometimes falls well short of it ; but it may be yellow 

 and preceded by a dark shade, well defined all the w T ay across. 

 Terminal area usually a little paler. Beneath yellowish to fuscous,
