form resembles niontara, and there is just a bare possibility that it 

 may be the female of that species. But the ground color is totally 

 different, the relative contrasts are not the same, and the Arizona 

 form gives the impression of a T^eniocampid, while the Calif ornian 

 form would be more readily referred to Perigea. Besides I do not 

 know of any similar sexual contrasts in this series. 



It should be said for both these species that the hairy clothing of 

 the eyes is very short, stiff and, apparently easily broken. A casual 

 examination might, therefore, easily cause an erroneous generic 

 reference. 

 Mamestra montara, new species. 



General ground color creamy gray, powdered with black and smoky brown. 

 Head and thorax without definite markings, the margins of patagia and tips 

 of tuftings somewhat more obviously darkened by the black scales. No dis- 

 tinct dorsal tuftings on abdomen. Primaries with all the normal maculation 

 marked, but incomplete and broken, the most obvious feature being a dusky 

 median shade which is rather evenly outcurved, is nearly parallel to the t. p. 

 line and crosses the reniform. Basal line distinct, rather well defined by 

 blackish shadings, a narrow black streak connecting it with base in the 

 submedian interspace, and an irregular blotch marking the outer edge at the 

 same point. T. a. line geminate, well removed from base, outwardly oblique, 

 a little outcurved in the interspaces, the edges incomplete and not well defined. 

 T. p. line geminate, very even, only a little outcurved over the cell and almost 

 evenly oblique below it : the defining lines not well-marked. Three rather 

 well-marked whitish dots on costa in the s. t. space. S. t. line marked 

 chiefly by the contrasting dark terminal space and by small irregular dusky 

 preceding shades. A series of black terminal lunules, which are preceded by 

 larger lunules of the pale ground, and thus stand out in some relief against the 

 dark terminal area. Claviform small, marked by black scales, not complete 

 in any example. Orbicular round or nearly so, moderate to large size, con- 

 colorous, completely defined or only by a small difference in tint. Reniform 

 rather large, ovate, oblique, not constricted, darkened by the median shade, 

 inwardly defined by black scales and a very narrow white line, outwardly with 

 a somewhat well-defined series of white dots, which are narrowly limited by 

 black scales. Secondaries whitish, semi-transparent, becoming dusky toward 

 the outer margin, which is bordered by a blackish line at the base of the 

 white fringes. A small discal lunule, visible from underside. A slight ex- 

 cision on outer margin below apex, not equally marked in all specimens. Be- 

 neath whitish, with variable, coarse dark powderings ; primaries a little smoky, 

 with a discal lunule and a variably defined exterior line ; secondaries with a 

 distinct discal lunule, the powdering most obvious along the costal area. 

 Expands, 1-1.08 inches = 25-27 mm.
