9. H. moclestella Clem. — " Forewings fuscous, the basal por- 

 tion of the wing paler and shining, and has a faint grayish hue ; in 

 the middle of the wing is a dark fuscous spot. Antennae, head and 

 labial palpi fuscous." The above very short description by Dr. 

 Clemens needs amplification. Labial palpi long and slender; head 

 and thorax grayish, speckled with fuscous. Forewings relatively wide, 

 the basal third limited externally by an angulated line, the dorsal 

 extremity of which is nearer the base than the costal end, the summit 

 of the angle nearer to the costa ; this space is grayish white, shining, 

 dusted with, and especially along the margins, dark fuscous-brown, 

 an ill-defined black spot before the summit of the angulated line, 

 remainder of wing dark gray, densely overlaid with dark fuscous, 

 especially in costal half of wing ; a dark spot before the middle of 

 wing just beyond summit of angulated line, two ill-defined spots at 

 end of cell ; the apical part of the wing is slightly sprinkled with 

 whitish scales ; cilia gray, sprinkled with fuscous. Hindwings not 

 quite 1, pale fuscous, cilia paler. Abdomen fuscous. Legs grayish 

 fuscous; hind tibia with an oblique, whitish, median band, tarsal 

 joints paler at apex. Expansion 15.0-16.0 mm., 0.6-0.64 inch. 



Hab. — Atlantic States. 



The type in fairly good condition in the collection of the 

 Amer. Entom. Society, Philadelphia, is a female, which I 

 have carefully compared with a specimen in my collection, 

 also a female. I have seen no male, and the presumption 

 that the male antennae are excised above the basal joint rests 

 entirely on the fact that Clemens placed it in his genus Holco- 

 cera — antennae excised above the basal joint. Mr. Busck's 

 statement* that this species is identical with Blastobasis 

 nubilella Zell., and Holocera glandulella Riley, is erroneous. 

 The last two named refer to one species and belong to the 

 genus Valentinia Wish. 



10. H. clialcofrontella Clem. (Plate II, figs. 17, Yla-d.) — 

 Head, basal joint of antennas and palpi, sordid yellowish, latter long, 

 recurved, third joint scarcely shorter than the second, the latter 

 externally except at tip, the terminal one entirely, thickly dusted with 

 dark fuscous. Stalk of antennas fuscous, except at its base ; excised 

 above basal joint with conical scale tuft and shortly ciliate in the 

 male. Thorax sordid yellow, dusted with fuscous, anteriorly purplish- 

 fuscous. Forewings relatively wide, ground color sordid yellowish or 

 yellowish-white, dusted with dark fuscous-brown, the dusting con-
