122 WILLIAM T. M. FORBES 



.4. hulstellus. Uncus (fig. 96) with points separate, down-curved; valves slender, 

 concave, uniform in width. 



There seems to be some confusion as to the identification of this species. In 

 the Barnes collection, the name is represented by a form with scattered white 

 scales on the fore wing, and with valves as in A. hulstellus. 



North Carolina, Texas. 



7. A. hulstellus Beutenmiiller. Similar to A. texanellus but larger and coarser, 

 with a strong, oblique, dark shade across the wing two-thirds of the way to the apex. 



Plummer's Island, Maryland, to Florida. 



8. A. mortipennellus Grote. Pale, dull brown, usually patchily marked with 

 dark brown; the discal spot most persistent. Female longer-winged and more 

 evenly yellowish brown. Uncus of male (fig. 98) much as in A. popeanellus, but 

 with the points somewhat enlarged and bluntly rounded; valves very slender, 

 constant in width, and evenly down-curved. R 3 and R, or R, and R 5 are often 

 stalked. 25-30 mm. (Hypoclopus Dyar). 



The distribution is uncertain. The material before me is from Missouri. 



IV. Palpus of male as in group III, but lolth somewhat heavier vestiture; 



palpus of female long, rather drooping, beaklike; thoracic vestiture as 

 in group III,' fore wing with all veins free; male antenna- with lamina- 

 tions hardly twice as high as the length of a segment. Male with long 

 supplementary process beside the valve. Eyes hairy. (Acrolophus) . 



9. A. plumifrontellus Clemens. Usually light reddish gray, with irregular, dark 

 striation, gathering into patches at end and near middle of cell, and also, basad 

 of middle and near middle of fold; these patches sometimes connected to form a 

 zigzag mark, but sometimes partly or wholly absent, especially in the female. 

 Rarely with but little or no reddish tint. (Fig. 97.) 35 mm. 



The moth flies in June and July. The southern race cervinus Walsingham 

 is somewhat smaller and more brilliant. 



Southern New York to western Pennsylvania and Florida. 



V. Fore wing with R 3 and R 4 invariably long-stalked; uncus simple. Eyes naked. 



( Hypoclopus ) . 



A. griseus Walsingham. Typically ashy white, often ranging from light blue- 

 gray to fuscous, with confused blackish markings. Hind wing brown. Valve broad, 

 oblique, narrow at base, squarely truncate. 22-25 mm. 



July. The eastern record for this species is based on a related but quite dis- 

 tinct, undescribed species, differing in structure as well as in its darker color. 



Texas; Arizona. 



Subfamily TINE1NJE. 

 (Tineidse, in strict sense) 



Head more prominent, though often with small eyes; eyes naked; palpus porrect, 

 or somewhat upturned in life, not large, clothed with scales and bristles, which are 

 regularly arranged in most cases; tongue usually present; maxillary palpus 

 usually folded, porrect in Amydria, absent when tongue is absent. Antenna typi- 

 cally with the basal whorl of scales on each segment reduced or replaced by a 

 whorl of bristles, often entirely concealed; the outer whcrl often raised at a sharp 

 angle, and when flat covering the whole surface of the segment, whereas the two 

 whorls (when there are only two) of the Adelidae and Acrolophinae are equally 

 developed and usually of contrasting colors. Outer whorl rarely somewhat inter- 

 rupted below, but antenna never laminate as in Acrolophinse. Head with rough, 

 bristly vestiture on both vertex and front, though comparatively smooth in the 

 Amydria group. Hind tibia often bristled, but not with a regular row of bristles. 

 Fore wing with Rj running to costa or apex. 



Larvae with front not reaching vertex; prespiracular setae of prothora-. (fig. 92)
