194 THE CANADIAN ENTOMOLOGIST. 



specimens it is mostly concealed by a thick sprinkling of blackish scales. 

 In worn specimens, much more of the groimd colour is in evidence and 

 there is a well-marked strigate appearance, especially outwardly. The 

 orbicular is present as a minute, inconspicuous dot, with black centre. 

 The reniform is to the naked eye the only contrasting feature in the 

 maculation, and even it is not very prominent. It is of the ground colour 

 with some white scales mixed, especially at lower end, and has a few 

 black scales around it, but the margin is not at all well defined. With the 

 lens a very faint dentate t. p. line can be made out. There is a faint 

 interrupted black line at base of fringes, which are slightly checkered. 

 The interruptions in the terminal line are due to faifft whitish points. 



Hind wings white, very slightly dusky outwardly and with fuscous line 

 at base of fringe, which is white. In the female, while the fore wings are 

 as in the c? > the hind wings are more fuscous outwardly and there can be 

 made out a very faint trace of mesial line. Head and thorax concolorous 

 with fore wings, abdomen whitish in male, somewhat darker in $ . 



Fore wings beneath fuscous, lighter along inner margin. Hind wings 

 with some fuscous scales along costa, faint discal dot. In the female the 

 shades are somewhat darker. 



Types, Southern Arizona, Pima Co. — This species can be readily dis- 

 tinguished by the pale contrasting reniform. 

 Platysenfa temecula, n. s. — $ . Expanse, 26 mm. 



Dark reddish-brown, with darker shades, veins darkened. A central 

 shade extends from base along median nerve to or beyond end of cell. 

 This is continued to margin, above inner angle, as a rather broad, though 

 not Ptrongly-contrasting, band. There is also a narrower shade running 

 from end of cell to apex ; the wing being a very little paler above and 

 below it. There are two well-marked black intravenular dashes beyond 

 cell. At end of cell is a short transverse white bar, preceded and followed 

 by minute yellow points. The mark, while distinct, is small, and the 

 df tail only to be made out with lens. There is a row of black terminal 

 lunules and the fringe is checkered, though not strongly so. Inconspicu- 

 ous pale points on costa mark inception of the transverse lines, which are 

 else barely to be made out, though indications of the t. p. can be faintly 

 traced under the lens by pale points. 



Hind wings fuscous, darker outwardly. Fringe paler, with dark line 

 at base. Head and thorax concolorous with fore, abdomen with hind 

 wings. Collar obscurely transversely banded.
