ANALYTICAL KEY TO SPECIES OF EUGROTEA. 



1. Veins of outer third fore wing outlined in wliite yavapai Kearfott. 



Veins not outlined in white dentella Fernald. 



EUGROTEA (?) YAVAPAI, new species. 



Expanse, 19-22 mm. 



Head whitish ochreous, speckled with brown ; palpi whitish ochre- 

 ous, shaded with brown externally and on top at base of apical joint; 

 maxillary palpi shaded externally at outer end with light brown; 

 antenna whitish ochreous, broadly annulated with brown, the latter 

 speckled with whitish ; thorax creamy ochreous, with whitish patches 

 in middle and on patagia, somewhat speckled with brown, especially 

 marginally and posteriorly ; abdomen pale ochreous, darker on dorsal 

 part of each segment ; legs whitish ochreous, tarsi banded with brown. 



Fore wing mottled white, ochreous and brown. The white oc- 

 curs in the base, dorsally, in the fold ; a transverse twice angulated 

 line in middle of wing, a broad patch on costa before subterminal 

 line; a small spot on costa at beginning of subterminal, a large spot 

 in apex, and on termen between the veins; between 2 and 5, the spots 

 are confluent; the white subterminal line is angulated outwardly to 

 vein 6, then inwardly to dorsum before tornus. The ochreous shades 

 are on inner half of costa, on upper and lower veins of cell, and in 

 the dark patch before the subterminal line. The dark brown is 

 dusted over the whole wing, except where the ochreous and white 

 replace it ; the most conspicuous marks are a prominent round spot 

 over upper angle of cell; two or three horizontal short lines in the 

 white patch on termen between 2 and 5; a costal spot between sub- 

 terminal line and white apical spot, a similar one below it; a termi- 

 nal line of brown is succeeded by a thin whitish line at the base of 

 the shining leaden brown cilia. 



Hind wing pale ochreous gray, cilia whitish. Underside both 

 wings whitish, the fore wing mottled with pale ochreous. 



Described from thirteen specimens; twelve from Yavapai County, 

 Arizona, April, from J. B. Smith; one specimen, Colorado, New 

 Mexico, at light, July 10, Cockerell, from National Museum collec- 

 tions. 



Coti/pes. — Cat. No. 11952, U.S.N.M., and in Author's collection. 



There is some variety in the intensity of the colors. Some speci- 

 mens have but little of the dark brown scaling, but there does not 

 seem to be any variation in the arrangement of the markings. 



I am in doubt where to place this .species. As will be .seen by fig. 4, 

 the outline of fore wing and venation are very different from nehii- 

 life7Xi Stephens, the type of genus Prionapteryx ,• it is nearer to 

 Siirattha Walker, differing in the simple antenna and in 6 and 7 of 

 fore wing from a point, but owing to stalking of 4+5 of fore
