AMERICAN MICROLEPIDOPTEKA. 109 



* 



wing length, not including the extreme costa and equidistant from the base at 

 both ends. Stigmata obsolete; a few white scales scattered over the apical part 

 of wing and the base of adjoining cilia, the latter grey. Hind wings greyish fus- 

 cous, cilia grey, paler towards theirbase. Abdomen brown above, segments 1-2 

 feebly teneous. Under side : thorax and femoivd silvery white, abdomen greyish 

 fuscous, spotted with darker scales and clothed with ochreous scales towards the 

 anal extremity. Legs brownish fuscous, middle and hind legs pale ochreous 

 within ; tarsal joints with a pale annulus at apex ; wings fuscous. 

 Expanse 11.-11.5 mm., .44-. 46 inch. 



Hab. -Hazleton, Pa. 



Two female specimens in ray collection. In appearance closely 

 resembling Pseudopigritia equitella. 



Differs from angustipermella by the somewhat narrower fore wing, 

 the straight fascia and absence of discal dots, from the following by 

 the fascia of fore wing. 



P. nrizonellsi sp. n. — Thorax, head and eye-caps greyish fuscous, antennae 

 dark fuscous. Labial palpi -male — very short, dark fuscous, terminal joint mi- 

 nute; female, distinct, drooping, pale, third joint much shorter than second. 

 Fore wings less strongly elongate, costal margin approximately straight; ground 

 color greyish white, costa fuscous towards the base: strongly tinted with pale 

 sulphur yellow in basal and middle part of wing; an illdefined pale fascia at 

 fully two-fifths the wing length and projecting irregularly into the disk exter- 

 nally, within the fascia there is some dark dusting; base adjoining costa dark 

 fuscous; immediately adjoining the fascia is a dark dorsal, and on opposite cos- 

 tal patch the latter elongate, triangular and more pronounced ; apical part of 

 wing more densely dusted with fuscous, condensed along costal margin and 

 somewhat interrupted by paler lines: 2 dark fuscous dots at end of cell and a 

 dorsal spot immediately below, the latter more elongate, apical part with a 

 sprinkling of white scales, cilia cinerous, sprinkled with fuscous and some white 

 scales, hind wings silver grey, cilia concolorous. Abdomen above ochreous, fus- 

 cous. Under side: thorax and femora silvery, abdomen pale ochJ^ous, legs dark 

 fuscous ; tarsal joints distinctly pale annulate at the apex ; fore wings dark fus- 

 cous, hind wings paler. 



Expanse lO.-ll. mm.. .40-.44 inch. 



Hab. — Huachuca and Nochales, Arizona. 



Two specimens, male and female, in my collection. Quite dis- 

 tinct and unlike any other species of the group known to me. A 

 somewhat aberrant form. The labial palpi of the female have the 

 first two joints relatively stouter than in the other species of this 

 genus, the terminal, minute, depressed somewhat similar to the 

 labial palpi of the female in Dnjope, to which at first I referred 

 this species. However, vein 4 and 5 of fore wings are distinctly 

 stalked. The palpi in the $ are drooping, v/hile porrect or subas 

 cending in the other species of the genus.
