Prionopteryx olivella n. s. 



<? . Antennae simple ; ocelli small but present ; hence this species 

 differs from Professor Zeller's diagnosis of the genus. External margin 

 of the primaries retiring below median fold where there is a projection of 

 the fringe. Maxillary palpi bushy, triangulate ; labial palpi much as in 

 Grambus. Front mucronate. Olive fuscous with whitish or yellowish 

 markings on the fore wings. A pale shade along submedian fold from 

 the base outwardly. A pale mark at middle of costa and a larger blotch 

 beyond it at apical third. An outwardly curved line on the costa be- 

 yond the blotch and seemingly the commencement of the sub terminal 

 line which it approaches on the median fold, but there terminates. The 

 narrow pale s. t. line itself is bent outwardly above the median fold, 

 running inwardly below it. The pale markings are relieved by darker 

 fuscous shades. There is a fuscous blotch on internal margin at basal 

 fourth and another at the middle which margins outwardly a very faint 

 angulated pale line which seems to connect with the first costal mark. 

 A narrow pale terminal hne discontinued along the upper portion of the 

 external margin. Fringes pale at base, fuscous outwardly. Hind wings 

 pale fuscous, with whitish, finely interlined fringes. Beneath without 

 markings; fore wings fuscous; hind wings soiled whitish. Head and 

 thorax like primaries ; palpi darker at the sides, light beneath. Ex- 

 panse, 25 mil. Hab. — Carboudale, 111., collected in June by Professor 

 French. 



In color this species is dull olive fuscous, there are no brown or cin- 

 namon brown shades ; the markings are narrow, of a soiled yellowish 

 white relieved by blotches and margining shades of darker fuscous. 

 My type is in nearly perfect condition, and fresh. 



Pemaldia n. gen. (Tineidae). 



This generic term is proposed for a stouter form than Psecadia, differ- 

 ing by the long, narrow, curved third palpal joint and in the neuration. 

 Face thickly clothed with spreading hair. Maxillary palpi long, hanging. 

 Eyes naked. Wings long ; fore wings 12- veined ; 4 to 8 out of the end 

 of the cell, the upper outer corner of which is divided off by a longitu- 

 dinal vein, the extension of vein 8 back to the main subcostal nerve 

 midway between the origin of 10 and 11. Hind wings 8-veined ; a cross- 

 vein from veins 7 to 3; 5 and 6 nearly from one point at the angulation 

 of the cross- vein ; median vein 2-branched. Labial palpi not exceeding 

 the front; third article longer than the thickly clothed second joint. 



Femaldia anatomella n. s. 



Light brownish ocher, reticulated with dark brown. Primaries al- 

 most entirely covered with a large dorsal black brown patch, leaving 

 the internal margin narrowly pale and the external margin more broadly 

 pale brown over apical half. Lower edge of the patch uneven, running 

 obliquely downwards and outwards from the base to basal third when it 

 runs in again, letting the pale ground color obtain triangularly at before
