has not the venation of that species, veins 3 and 4 of fore 

 wings being well separated as in cupidinella Hulst. 



Pectinigera (Cayuga) pamponerella, n. sp. 



Palpi long, porrect, perfectly straight, the second joint conivex 

 above. Pale ocherous, shaded with vinous. Fore wing with the costa 

 broadly and evenly white, vinous shaded, the rest of the wing of the 

 ocherous color; a fine black line along subcostal vein and vein 6 in 

 one specimen followed by a faint blackish shading over the cell, the 

 other specimen without the black line and the shading fainter. Hind 

 wing faintly fuscous tinted in the dark specimen, whitish ocherous in 

 the other. Expanse, 27 mm. 



Two males, Chimney Gulch, Golden, Colo., August 12, 1907 

 (E. J. Oslar), from Mr. F. Haimbach, who has kindly per- 

 mitted me to keep one type for the National Museum. 



Type. No. 11854, U. S. National Museum. 



Similar to P. (C.) gemmatella Hulst, but the costal stripe 

 reaches the apex of the wing instead of terminating before 

 it, and the color is not so red. 



Ollia holoponerella, n. sp. 



Palpi long, porrect, gently and regularly downcurved. Ocherous, the 

 palpi grayish tinted on the outside. Fore wing yellowish ocherous, 

 with a few gray scales toward the outer margin, the costa broadly and 

 straightly white with a fine black line along the subcostal vein. Hind 

 wings whitish stramineous. Expanse, 27 mm. 



One male, San Bernardino Ranch, Cochise Co., Arizona, 

 3750 ft., August (F. H. Snow). 



Type. No. 11855, U. S. National Museum. 



This pattern of coloration is extremely common in the sub- 

 family, but most of the species so marked are smaller. The 

 size is the same as in the foregoing, Pectinigera pamponerella, 

 and I at first thought it to be the same species. However, 

 there is no tuft of scales discernible on the antennae, the palpi 

 are distinctly downcurved, the serrations of the antennae are 

 pointed teeth instead of quadrate plates (as in pamponerella), 

 while the color is ocherous, without any red tint. 



Pectinigera (Cayuga) bistriatella Hulst. 



Ragonot makes this a synonym to gemmatella Hulst, and 

 Doctor Hulst records it as a variety of the same in Bulletin 

 52, U. S. National Museum, presumably out of deference to 

 Ragonot's opinion ; but it is clearly distinct. I have no present 

 notes of the type, but from the description it must be closely 

 similar to Peoria discostrigella Dyar. In fact I have but little
