TRACHOMA Wlgrn. 



Trachoma senex sp. n. 



Palpi, tawny, profusely sprinkled with gray; the upper surface of the second joint 

 and the apical joint almost entirely hoary-gray. 



Antemue, tawny, faintly annulated with gray. 



Head, tawny; face sprinkled with gray. 



Thorax, tawny. 



Fore-wings, tawny, sprinkled and transversely streaked with hoary-gray, having sev- 

 eral patches of raised tawny scales on the basi-dorsal half of the wing, and one 

 before and above the anal angle ; the hoary-gray sprinkling on the basal half of 

 the wing is interrupted by slender lines of tawny scales, and some chestnut-brown 

 is scattered about the fold and the base below the costa; at the middle of the 

 costal margin is a dark tawny-fascous patch, containing some raised scales, and 

 followed by a chestnut-brown shade, sprinkled with hoary, at its upper edge, 

 and crossed by two longitudinal tawny lines on its lower half; adjacent to the 

 outer end of the lower line is a short oblique streak of pure white; the apical 

 portion of the wing on tbe costal margin is thickly sprinkled with hoary-white, 

 except the extreme apex, where the chestnnt-browu predominates; the apex is 

 falcate, and immediately below it is a pale fawn spot in the cilia ; below this the 

 cilia are bright chestnut-brown to the anal angle, where a few tawny-gray scales 

 are intermixed. 



Hind-wings, gray, with a faint purplish tinge ; cilia somewhat paler. 



Abdomen, gray; anal tuft inclining to ocherous.

Habitat, a single 9 , for which I am indebted to Professor Riley, is labeled " Placer 

 County, Cal., Aug." 



Type, 9 , Mus. Wlsm. 

 This species is allied to the European Trachoma horridella Tr. but differs in the 



abundance of hoary scales, in the oblique white spot at the end of the cell, and in the 



chestnut-brown on the costa and at the anal angle. 



PTEROLONCHE Z. 



Pterolonche lineata sp. n. 



Head, antennce, and pal2)i,houe-co\or ; the antenniii strongly setulose; palpi porrect, 

 somewhat arched, apex slightly depressed, extending to the length of, approxi- 

 mately, 5'""'. 



Fore-ivings, hone-color, marked throughout with slender longitudinal lines of a darker 

 bone-gray tint, following the veins and the fold and evenly distributed over the 

 wing, as well along the upper portion of the discal cell as beyond its margins ; 

 counting these lines across the wing, 8 are distinctly traceable, and a rather 

 short one, tending inwards from the end of the cell, lies between the 4 upper 

 and 4 lower ones ; cilia, smoky-gray. Under side somewhat darker than the up- 

 per side, having a besmeared, smoky tinge, except along the extreme costal and 

 dorsal margins.
