edged with a fine black line, and this in turn edged by a more or less obvious 

 layer of white scales. The ordinary spots are fused, the long narrow orbicular 

 joining the reniform at its middle. A narrow black line inwardly edged with 

 white scales defines the combined stigma. There is a distinct, rather broad, con- 

 tinuous black terminal line, beyond which the fringes are gray and white lined. 

 There is a whitish shade preceding the oblique dark shade on costajust before 

 the apex and sagittate black spots precede the s. t. line in part of its course. Sec- 

 ondaries whitish in the male, smoky in the female, a little darker outwardly in 

 both cases and with a darker terminal line basing the white fringes. Beneath : 

 powdery ; primaries with the disc smoky and a white line at the base of the 

 fringes which are also cut with white; secondaries with an obscure discal lunule, 

 a punctiform extra-median line and a smoky terminal line. 

 Expands .72-.84 inches ^= 18-21 mm.

 fornia, in April (Hutson) ; Gila County, Arizona, in June (Poling);

Five male and thirteen female specimens, mostly in good condi- 

 tion and mostly of the desert material sent in by Mr. Hutson. 

 There is a little variation in the distinctness of maculation, and the 

 males are uniformly smaller and paler than the females. In tlie 

 strigate type of maculation this species resembles fusimacula, but is 

 smaller and with more obtuse and broader primaries. From the 

 more typical species it is separated by the character of the posterior 

 thoracic tuft, which is not metallic and does not consist of broadly 

 flattened scales. It is really more like a very small Oncocnemis of 

 the chandleri group, and not unlike gracillima Grt. 



Oxyciieiuis adustiis n. sp. 



Ground color dull ashen-gray over luteous. Head chocolate-brown in front, 

 vertex and thorax powdered with black scales, posterior tuft a little darker. Pri- 

 maries obscurely marked. Basal and t. a. lines lost. There is a long concolorous 

 claviform, very faintly indicated by scattered white scales, which extends nearly 

 to the t. p. line. The t. p. line is smoky brown, single, followed by a narrow 

 paler shade, acutely angled over the cell, thence evenly oblique to the inner mar- 

 gin a little beyond the middle, both brown and pale shadings better marked to- 

 ward the margin. S. t. line very irregular, broken, whitish, preceded by darker 

 shadings and interspaceal black lines; forming more conspicuous blotches oppo- 

 site the cell and in the submedian interspaces. There is a whitish streaking from 

 the inner costal inception of the s. t. line and the reniform. The ordinary spots 

 are concolorous, narrowly and obscurely white ringed, confluent, the elongate 

 orbicular entering the centre of the reniform. Terminal line black, distinct, con- 

 tinuous, the fringes gray at base and with a yellowish interline. Secondaries 

 smoky whitish, darker at the outer margin, fringes white. Beneath smoky, pri- 

 maries more luteous, with broad fringes alternately lined with white and gray ; 

 secondaries whitish.
