Maniestra circumcincta, bp. iiov. 



Head and thorax dark gray with a brownish admixture. Collar in 

 feriorly more brownish, crossed by a bUick line, white tipped. Patagiae 

 black margined. Primaries dark gray, with a variable reddish admix- 

 ture, obvious always in the s. t. space; median si)ace more blackish. 

 Basal line distinct, geminate, black margined; inclndcd space paler, a 

 curved black mark emphasizing its lower external boundary. T. a, line 

 oblique, outcurved between veins, geminate, black, the included space 

 paler. T. p. line geminate, black, outer line less distinct, included space 

 paler, outcurved over cell and evenly obliiiue below. S. t. line irregu- 

 lar, faint, narrow, marked by a preceding dusky patch in s. t. space on 

 costa, and the darker terminal space, white marked opposite anal angle. 

 An interrupted black line at base of fringes, which are cut with pale. 

 The claviforni is small, but distinct and black r nged. Orbicular con 

 colorons or a little paler, irregidarly ovate, obliipie, incompletely black 

 ringed. Keniform upright, small, centrally constricted, white ringed 

 as in its allies. Secondaries whitish gray, sometimes with a brownish 

 admixture, with a vague dusky discal lunuleand a dusky terminal line. 

 A yellowish line at base of fringes. Beneath, whitish, powdered with 

 black, a vague outer line and discal spot ou secondaries. 



Expands 25-29""" (1 to 1.16 inches). 



HAT3ITAT. — Sierra Nevada, California, 



Both sexes are from Mr. Edwards's collection. There is a difference 

 in the amount of reddish admixture in the two specimens before me, 

 the female inclining to the cinnabarina type, while obviously different 

 by the squammose vestiture and complt^te black lines, and the male re- 

 sembling oUvacea so strongly that I compared it closely at first, expect- 

 ing a variety of this protean form. The sexual characters, however, 

 refer the species to the renigera group. 



Group OLIVACEA. 



The species of this group agree in small size, rather robust form, in 

 short stumpy primaries and distinctly tufted thorax and abdomen, the 

 latter in the $ also with lateral tufts. In appearance, i. c, wing form 

 and habitus, the Sj)ecies are related to the renigera group, from which 

 they differ in the form of the male genitalia. This is alike in all the 

 species referred here. The harpes are broad at base, rather abruptly 

 narrowing and then again gradually widening into a rounded, concave 

 lapi)et which is inwardly spinulose at til). The clasper is moderately 

 curved and corneous, half the length of the hari)es. 



Three species are referred here, separated as follows : 



T. p. liue siuuate, incurved below reuiforni ouvacra. 



T. p. lino rigidly oblique from subcostal kf.ctiuxea. 



Median lines unusually approximate, curved towanl center of wing, and almost 

 touching at inner margin vau-media.
