In general characters, however, it seems closely related to castor and 

 mizar, and with them to stand most satisfactorily in this place. It is 

 very different from any other species known to us, though it resembles 

 castor superficially as we have already noted. 

 We know nothing of the early stages. 



13. OlDAEMATOPHORUS MIZAR n. Sp. PI. XLVII, fig. 12. PI. LII, 



fig. 2. 



Brownish gray, front of thorax and head largely white. Thorax tipped 

 behind with a V-shaped white mark. First two segments of abdomen with 

 some black on posterior margin, followed by white on following segment; 

 remainder with white posterior margins ; a lateral white line is present. Palpi 

 moderate, oblique, white, touched with gray-brown below at tip of second 

 segment. .Antennae white with dark dots above. Legs white; fore tibiae with 

 brownish black stripes inside and a moderate tuft of mixed dark and light scales; 

 mid tibiae with two such tufts; fore and mid tarsi with slight dark annuli at 

 tips of joints; hind legs with dark bands at bases of spurs, a broad terminal 

 annulus on first tarsal joint and slight annuli on remaining four. 



Primaries brownish gray with white streaks, the restricted areas of ground 

 color usually sprinkled with 1 lackish scales. The white vestiture clothes the 

 wing at base of cleft, where it is inwardly limited by the usual subtriangular 

 spot which is here broadly connected with the costa, and spreads out over the 

 first lobe. This spot also sends a variably broad streak toward outer margin 

 of second lobe. On each side of the base of the cleft is a fine black streak, 

 fading outwardly into the grayer lobes, and in the first lobe a second heavier 

 streak in basal half, two dots on costa, one cit apex, and one before it on inner 

 margin. In the second lobe there may be a black apical dot, a subapical dot or 

 streak on outer margin and a few other black scales. In the disk there is a 

 subcostal white line, rather vague, a dash in the cell, preceded by a spot rather 

 darker than the ground color, a large white spot between cell and inner margin 

 about one-third from base of wing, and an almost longitudinal white line, pre- 

 sumably on the base of Cu... In addition the dark areas, particularly toward 

 the base, are more or less irrorate with white. Fringes variable, but always 

 brownish gray cut with white, with darker bases. Secondaries and their fringes 

 brownish gray. Expanse 24-29 mm. 



Described from fifteen specimens from Arizona and N. M. Holotype

 Barnes. Thirteen paratypes, 3 $ and 10 9 , from Redington, Palmerlee, Here- 

 ford, White and Chiricahua Mts. and Mohave Co., and a single 9 from Jemez 

 Springs, N. M., distributed as follows : <? and 9 , U. S. N. M. No. 23467, 1 9

 Barnes. We have also a specimen from Mohave Co. taken in October. 



This and the following species are superficially rather similar, but 

 uticar is larafer and the thorax differs as noted in the key. Tlie four
