primaries^ it forms a tuft of yellow scales, most obvious in the male and 

 not always present. Primaries with the median lines obscured and no 

 strong contrasts. Basal line geminate, sometimes marked on the costa 

 only, but often complete and relieved by yellow, included scales. Trans- 

 verse anterior line geminate, usually traceable by black or smoky scales 

 across the wing; in course a little outwardly oblique, aud slightly out- 

 curved in the interspaces. Transverse posterior line geminate, trace- 

 able with difficulty in some examples, obsolete in others. Sub terminal 

 line pale, irregular, always broken, usually only scattered yellow scales, 

 which are often altogether absent. Sometimes the yellow scales are 

 emphasized by preceding black atoms, and in one case the line is marked 

 by a somewhat deeper preceding shade. Terminal line narrow, black, 

 relieving a yellow line at the base of the fringes. Claviform small, 

 traceable in all the specimens, not complete in any. Orbicular large, 

 oval, irregular, oblique, concolorous, more or less completely outlined 

 by black scales, within which, in some specimens, yellow scales tend to 

 bring it into relief. Eeniform large, kidney shaped, extending below 

 the cell, more or less imperfectly outlined by black scales, and usually 

 better defined by an inner ring of yellow or whitish scales, which may 

 invade the spot centrally. Usually the center is concolorous, but it 

 may be slightly darker. Secondaries dirty yellowish white, outwardly 

 smoky, the female more yellowish, with a broader soiled margin, discal 

 lunule evident, fringes white, with a yellow line at base and a smoky 

 line beyond this. Beneath gray, powdery, with the usual tendency to 

 an outer line and a discal spot on all wings. 



Expanse, 32 to 35 mm. = 1.28 to 1.40 inches. 



Sahitat. — Grienwood Springs, Colorado, August, September, October 

 (Barnes); Colorado (Bruce) ; Pullman, Washington, July (Piper). 



Six males and four females are at hand. They vary from a mouse 

 gray to a red brown in ground color, and from almost immaculate to a 

 type in which all the markings can be traced by darker or paler scales. 

 The best-marked specimen resembles a normal tessellata without the 

 black, and in fact this species resembles the common form when all its 

 characteristic markings have been washed out. It is perhaps even 

 closer to satis, which is larger, better marked, has a black line across 

 the collar, and a broken, black, longitudinal line at base. 



Type.—Csit. No. 4798, U.S.N.M. 



43. CARNEADES OBJURGATA, new species. 



Ground color red brown, more or less overlaid by violet scales, less 

 marked in the male, which tends to rusty shadings. Head violet in the 

 female, often rusty in the male, palpi dusky at the sides. Collar with 

 a brown or blackish median line, which is margined above by violet 

 scales, inferiorly a little paler or even rusty yellow, in which case there 

 is a patch of rusty scales at the base of the primaries. Primaries with 

 all the markings present, the surface powdery and mottled with black,
