out fossa. Anteuuse rather stout, pale fuscous, indistinctly annulate. Labial 

 palpi extremely short, pale ochreous. Fore wings with the costa convex from 

 the base, slightly depressed along middle third ; ground color silver grey, over- 

 laid with pale fuscous; costal half of base overlaid with golden. The basal space 

 extends to about one-third the wing length, paler than rest, very thinly dusted with 

 fuscous, darker along the costa and close to the base, with an elongate fuscous dot 

 in its centre and sending a prolongation into the disk of the wing in the middle; 

 rest of wing darker immediately adjoining the basal space, thence paling toward 

 the apex, a somewhat paler dorso-discal area opposite to beginning of costal (dlia, 

 containing two dark dots, the upper on the anterior angle of the cell, the other 

 immediately below ; costa and extreme apex more deeply fuscous, apical part 

 and adjoining cilia thinly sprinkled with white scales; hind-wings and cilia of 

 both greyish fuscous. Under side of thorax and femora silvery white, legs fus- 

 cous; tarsal joints annulate with pale at apex ; the fuscous scales are tipped with 

 pale. Abdomen wanting. 



Female. — Thorax, head and eye-caps grayish to subaeneous fuscous, metallic 

 reflection much less pronounced, golden tint at base of fore wings absent. Labial 

 palpi quite distinct, basal joint with stiff, bristle-like scales beneath, dusted with 

 fuscous, joints 2-3 pale yellowish, terminal distinctly .shorter than second joint. 

 Abdomen pale fuscous above, silvery white, slightly dusted with fuscous beneath. 



Expanse 12. mm., .48 inch. 



Hab. — Hazleton, Pa. ; Iowa and Lawrence, Kan.sas. One speci- 

 men from each locality in my collection. A very distinct species. 



P. latiicapitella Clem. (PI. VI, fig. 3). Male. — Greyish fuscous; thorax, 

 head and eye-caps tawny, with brassy lustre, antennae fu.scous. Labial palpi 

 very short, stout, compressed, fuscous, first joint with blackish hairs beneath ; 

 third very short. Fore wings: costa convex from the base, ground color silver 

 grey, nearly concealed by fuscous scales, with a purple reflection in certain 

 lights; a whitish fascia at one-third the wing length, slightly curved and some- 

 what inflexed at the dorsal margin; costa more deeply fuscous, apical part of 

 wing and adjoining cilia sprinkled with white and dark fuscous scales, the former 

 aggregated into an indistinct subapical fascia; dorsal cilia like the hind wings 

 and their cilia, greyish fuscous. Abdomen fuscous, first two dorsal segments 

 tawny fuscous, with a cupreous lustre. Underside: thorax and femora silvery 

 white, dusted with fuscous; abdomen fuscous; legs fuscous, sprinkled with pale 

 scales, tarsal joints with a pale annulus at the apex. 



Female. — Thorax, head and antennal eye-caps a little darker and of a more 

 ieneous lustre; labial palpi slender, dark fuscous, joints 2-3 equal in length, less 

 prominent and distinct than in the preceding species of the genus. The purple 

 reflection of the fore wings more distinct and becoming brassy towards the base. 



Expanse 10.5-12. mm., .42-.48 inch. 



Hab. — All the material before me was taken here (Hazleton, 

 Pa.). Probably occurs over the entire middle Atlantic district. 



The type of the genus and the bete >ioir of the species of this and 

 the preceding genus. However, 1 entertain no doubt of this being 

 the true laticapitella of Clemens, of which he says*: "Labial palpi
