iuto the dorso-apical white part; beyond this costal white streak are five others, 

 which likewise extend across the costo apical brown to the dorso-apical white 

 part of the wing, thus dividing it into a number of large spots; the first of these 

 five streaks is oblique, the others perpendicular to the costal margin, and the 

 space or brown spot between the second and third is larger than that between 

 the others. Dorsal cilia brown with numerous narrow white streaks running up 

 through them from the dorsal white margin. In the basal half of the wing 

 there is a narrow white line extending along the fold, and an oblique white costal 

 streak which almost reaches the fold. Face and palpi grayish fuscous. Under 

 surface of body and the legs yellowish. Alar expansion a little over one-fourth 

 of an inch. Bosque County, Texas. 



The above is Mr. Chambers' description which agrees with the 

 well-preserved type in Cambridge. The forewings are somewhat 

 falcate, or perhaps better the outer half of the dorsal margin appears 

 somewhat emarginate; the space between the second and third 

 oblique streak spoken off in the text appears to me rather smaller 

 than the preceeding interspace. Hindwings narrowly lanceolate; 

 cilia 3. Forewings without scale tufts. Second joint of labial palpi 

 with a few seta?, third joint short, obtusely pointed. 



H.? lieteropalpellan.sp. — PI. Ill, fig. 3. — Palpi sordid white; third joint 

 of labial palpi, except the apex, fuscous. Head sordid white, intermixed with 

 brown on the vertex. Antennae yellowish white, annulate above with brown. 

 Thorax whitish, patagia brown in front. Forewings sordid white, sprinkled 

 with golden brown scales, somewhat arranged in irregular transverse lines; a 

 velvety, dark brown spot on extreme base of costa, from which extends a line 

 obliquely to fold and thence perpendicularly to the dorsal margin ; an oblique 

 costal spot at one-third, an irregular transverse band at two-thirds, between the 

 two latter, is a smaller costal spot and a similar spot between the band and apex ; 

 a rather large spot in middle of dorsal margin and a small dorsal spot opposite 

 the last costal one ; a round spot at the extreme apex. Cilia whitish sprinkled 

 with dark brown scales; all the dark brown spots consist of semi-erect scales. 

 Hindwings silver gray; cilia pale gray, faintly yellowish at base. Abdomen 

 grayish fuscous. Legs ochreous white ; anterior and middle tibise and tarsi 

 tinted with fuscous. 



Exp. 8.0 mm. ; 0.32 inch. 



Hab. — Maryland (Plummer's Island). 



A single female specimen was received from Mr. A. Busck and 

 is now in the National Museum collection. 



A very peculiar species, which no doubt, on careful study of its 

 venation in connection with the following structural characters, will 

 prove generically distinct. Maxillary palpi unusually developed, six 

 jointed, folded ; first joint about as long as the following five joints 

 together, the latter scaly and overlapping the labial palpi ; latter 

 cylindrical moderately thick, second joint with apical seta?, third joint
