76 JOHN B. SMITH. 



Secondaries white, witli an outer smoky niarjrin, which runs out at anal angle. 

 Beneath, i)riniaries smoky, tending; to yellowish at hase ; secondaries whitish. 

 Expands 21-26 mm. =.84-1.05 inches. 



Hab. — Colorado; Bluff, Utah ; Texas in May. 



Three males and seven females are at hand and I have seen 

 many others. The primaries are moderate in length, proj)ortionally 

 rather broad, trigonate. The secondaries are as in neocula as to 

 venation. 



The general range of variation has been fairly stated in the de- 

 scription, and it consists chiefly in the amount of gray shading 

 along the costal region toward base. We have in this species a 

 decided indication of the reniform spot, and in the square termina- 

 tion of the white space on the costa, a decided tendency toward a 

 square suba{)ical patch, which is further intensified by the gray 

 shading from costa, which, in one example, all but cuts off such a 

 spot. 



Acontia behrii n. sp. 



Head and thorax white; ahdomen with a slightly yellowish tings. Primaries 

 white from base to the middle on the inner margin to a brown shade, which is 

 sharply defined and extends obliquely outward to the outer median vein, is there 

 squarely upright to the upper angle of cell, and then forms an abrupt step whi('h 

 extends nearly to the s. t. line. The white shade here forms an outward tooth, 

 and is then oblique to the costa at middle of s. t. space. Basal line indicated by 

 geminate gray costal clouds. T. a. line geminate, gray, complete in the specimen 

 before me. A gray cloud indicates the beginning of the t. p. line. The outer 

 dusky shade is mostly dull brown to the s. t. line. The median shade line is 

 blackish and extends from vein 3 to the iuner margin. S. t. line a slender, zig- 

 zaged blue line, partly preceded and partly followed by a darker, umber-brown 

 shade. A black dot follows it opposite the hind angle. Terminal space mostly 

 blue, white from a little over middle to near the inner angle. S. t. line irregular, 

 narrow, incomplete, whitish. Fringes steel-gray or bluish at apex and inner 

 angle, else whitish. A slender, broken, black terminal liiie. Neither orbioilar 

 nor reniform marked in the specimen. Secondaries white, with a bluish reflec- 

 tion and a smoky outer margin, widest at apex. Beneath, primaries smoky, 

 tawny toward base and along costa; secondaries white. 



Expands 25 mm. = 1. inch. 



Hab. — California. 



A single nuile example given me by Dr. Belir wlio had others. 

 I do not recollect, if I was told, from what especial region this 

 came. At ail events the species is a very good one, differing from 

 its immediate allies in the much sharper niaculation, which is not 

 smootii or glossy gray and is without olivaceous shading. 



The primaries are a little broader than in cretata and compara-
