basal area. Some golden brown .scales are at the extreme apex, extending on to the 

 fringes at that point. A black terminal line, broken on the veins. Fringes white 

 except at apex, opposite the cell and at anal angle, where they are slaty gray brown. 

 Secondaries whitish at base, becoming smoky outwardly. Fringes white, with a 

 smoky brown line at apex. Beneath, primaries smoky, with a yellowish tinge, costa 

 whitish with the dark blotches of the upper side more faintly reproduced. Secondaries 

 whitish with costal margin powdery, outer margin narrowly smoky, and a smoky 

 discal lunule. Expands .80 inch ^= 20 mm. 



Habitat. — Walters Station, California, in March (Geo. S. Hutson). 



A single male, in good condition taken in the Colorado desert. 

 These species resembles laiiceolata and belongs with it ; but it is much 

 smaller, the head is brown, and the collar is white at the extreme base 

 only. The maculation differs considerably in details, the new form 

 being really in this respect somewhat intermediate between lanceolata 

 d.\\A go)iella. The front is normally convex only, vein 5 of the secon- 

 daries is practically obsolete, and veins 3 and 4 fork half way between 

 the end of the cell and the outer margin. 



Acontia semiatra, sp. nov. 



Head and thorax creamy white or yellowish with a slight reddish tinge, imma- 

 culate. Abdomen a trifle smoky, the margins of the segments narrowly white-ringed. 

 Primaries, basal space, creamy yellow with a slight reddish tinge, and this is the 

 underlying ground color. Basal line marked by a blackish spot on costa, and some- 

 times by another on the median vein. Median space a slaty, somewhat glistening 

 black ; almost solid in same specimens, usually a little mottled over the cell. The 

 t. a. line is defined by the inner boundary of the median space, very even, with a 

 slight outcurve centrally. The t. p. line is defined in the same way as the outer 

 boundary of the median space, very evenly outcurved over the cell and somewhat 

 irregularly incurved below : — the edge in the submedian interspace being somewhat 

 jagged. Beyond this line is a shading of the yellowish ground, narrow and some- 

 times linear from the costa to the middle of the wing, but usually filling the sub- 

 terminal space below that point. Terminal space blackish-gray, s. t. line veiy irreg- 

 ular, broken, whitish, sometimes barely traceable. A series of small white venular 

 dots at base of fringes. The ordinary spots are much obscured or barely traceable. 

 The orbicular may be guessed at as a more intensely black spot just without the inner 

 margin of the median space on the cell. The reniform is usually obvious, though 

 not defined ; consisting, when best marked, of a larger inferior and smaller superior 

 black spot, vaguely outlined by a yellowish shading. Secondaries smoky, paler at 

 base, the fringes whitish. Beneath, a pale, smoky, iridescent yellowish, without 

 obvious maculation ; but on the primaries, with a faint reflection of the upper surface. 

 Expands .80-. 85 inch = 20-21 mm. 



Habitat. — Quartzsite, Yuma Co., Arizona, in March (Geo. S. 

 Hutson).
