142 AMERICAN LEPIDOPTERA. 



size from a mere dot to a blotch and may be geminate. The t. p. line is traceable 

 in some examples by dotted marks until it merges into the large brown patch 

 that occupies the third quarter of the inner margin and extends upwards to the 

 middle of the wing. This patch is not of solid color, but rather of wavy bands, 

 and the t. p. line is indicated by black scales. There is another brown blotch at 

 the apex, and in this the s. t. line is marked by intensely black scales. In all the 

 brown patches there are some metallic-blue scales. A complete series of black 

 terminal spots. Orbicular absent. Eeniform traceable in all speciniens, but varies 

 from a pair of narrow black short lines to a leaden-gray spot, with or without 

 defining black scales at sides. Secondaries dirty white at base, outwardly smoky, 

 fringes whitish. Beneath: primaries yellowish, outwardly smoky and mottled 

 to obscurely reproduce the markings of upper surface; secondaries whitish, with 

 a narrow dusky outer margin and a dusky discal lunule. 

 Expands .75-.82 inch = 19-21 mm.

Five male specimens, all in fair or good condition. The species 

 is allied to gonella and flavicollis, but is smaller and differs from 

 both in having the maculation chocolate-brown instead of blackish 

 or leaden gray. The thorax is not so completely brown and the 

 markings of the primaries are much more fragmentary. It differs 

 further in the complete absence of the orbicular. 



Yrias terminalii^ n. sp. 



Similar to volucris Grote in maculation and general appearance, but much more 

 contrastingly marked. The ground color is distinctly more yellowish and mot- 

 tled, without the even bluish shading described by Mr. Grote, and the lines stand 

 out in good contrast, although they are not black as in repentis. A rusty brown 

 shade line accompanies the t. a. line outwardly, another crosses the wing just be- 

 yond the median line, the s. t. line is partly of the same color, and a well-marked 

 rusty shade borders the s. t. line outwardly. The s. t. space tends to break up 

 into a dark costal, a central and an inner marginal dark blotch, the central blotch 

 extending into the terminal space. Secondaries also more yellowish and with 

 more contrasting lines than in volucris. 



Expands .95-1.05 inches = 24-26 mm. 



Hab. — Yavapai County, Arizona, May 20th to 30th. 



Three males and three females from Mr. Hutson, sent in with a 

 lot of volucris and clientis. From the lot of 40 vohicris before me, 

 these six specimens stand out distinctly by their mottled appearance, 

 and their is no intergradation. In fact, there is little variation in 

 this genus, the 60 or more clientis being almost alike. In volucris 

 and terminalis the last segment of the abdomen of the female is 

 rusty brown at the tip, and the lateral incisures of the ventral sclerite
