the lines have a decided brownish tinge and are usually more 

 sharply defined, but sometimes there is a tendency for the three 

 lines in the middle of the wing above the fold to coalesce. 



COLEOPHORA ATKOMARGINATA, n. Sp. 



Basal joint of the antennae with a long, dense, projecting tuft of 

 yellowish white scales ; antennal stalk white conspicuously annu- 

 lated with dark brown. Palpi yellowish white, with tuft of scales 

 on the second joint. Head and thorax white, with a faint yellow 

 tinge, especially on the patagia. 



Fore wings white, longitudinally marked with very distinct 

 brownish ocherous lines. The extreme costal edge, from base to 

 cilia, is of this color. A narrow line starting from the b?se forks 

 about the basal third. The upper branch, gradually broadening, 

 runs parallel to the costa, reaching the margin just beyond the 

 beginning of the costal cilia; from thence it runs along the base 

 of the cilia to the apex. Its outer ti\gQ at the base of the cilia 

 is margined with brown scales. The lower branch, also broad- 

 ening slightly, extends almost parallel to the fold and reaches the 

 margin just above it; this line also runs along the margin at the 

 base of the cilia, meeting the upper branch at the apex of the 

 wing. The two branches thus enclose between them a streak of 

 the white ground color. There are also two little patches of white 

 scales in the broad part of the upper branch just before the tip 

 of the wing. Beneath the fold there is a narrow streak of the 

 same brownish ocherous color. There is a line of black-tipped 

 scales running through the middle of the costail and apical cilia, 

 which extends just around the apex of the wing and then ends 

 abruptly. Cilia pale ocherous, darker opposite the tip of the wing. 

 Hind wings pale fuscous, cilia tinged with ocherous. 



Abdomen brownish ocherous, shading to blackish near the tip, 

 anal tuft white. Legs white, except the tarsi of the hind pair, 

 which are annuilated with brown. 



Expanse ; 10.5 mm.
