THK CV>f APIAN KNTOMOLOCIST. 71 



maci'.lation. Beneath powdery, primaries darker with a vague tendency 

 to reproduce the maculation of upper side : secondaries paler, darkening 

 outwardly ; with two smoky bands across the disk and, in the outer dark 

 space, a narrow, pale, submarginal line. 



Expands: i inch = 25 mm. 



Habitat : Oak Creek Canyon, Arizona, 6,000 feet, August. 



One male and one female in fair condition, from Prof. F. H. Snow. 

 The species is one of the smallest of the genus and belongs with sobrialis 

 and larvalis as well by general colour as by the angulated exterior margin 

 of primaries. It differs at once, however, in the very distinct, rigidly 

 oblique median shade as well as in the details of the maculation generally. 



SiMPLICIA ALBISINUATA, U. Sp. 



Ground colour deep smoky-brown, no contrasts except for the 

 sinuate, white s. t, line of the primaries. Head and thorax concolorous, 

 the abdomen paler. Primaries with the median lines vaguely traceable, 

 darker, irregular. S. t. line obvious or prominent ; pale or even white, 

 with an obvious incurve opposite the cell, else rather even. Terminal 

 line pale, narrow, sometimes obsolete, preceded by blackish lunules, the 

 fringes slightly indented. Orbicular a diffuse spot, a mere dot, or altogether 

 wanting. At its best with a bluish white central dot. Reniform 

 large, kidney shaped, always in part obscure,, sometimes a diffuse blotch, 

 usually with the inner margin marked by a few bluish white scales with a 

 blackish surrounding. Secondaries with an extra median paler shading, 

 vaguely marked ; the fringes a little paler. Beneath a little paler and less 

 smoky than above, more powdery ; with a whitish, irregular s. t. line, 

 broken on the primaries and, on the secondaries, a somewhat obscure 

 median shade line and discal spot. 



Expands: i. 38-1. 50 inches = 34-37 mm. 



Habitat : Cochise County, Arizona, July and August. 



Three males and three females from Mr. Franck, all received in 

 papers and in more or less defective condition. In 4 of the examples 

 the apices of primaries are distinctly acute, in the others the wing is 

 broader, all the margins a little fuller and the apex not so obvious. 



This is the first occurrence of this interesting Central American genus 

 in our fauna and the species is evidently allied to ao?iia, Druce, recorded 

 from Panama and Guatemala. In the lists the species may be placed 

 next to Paithis, with which the genus agrees in the exaggerated tufts of 

 the legs and palpi in the male.
