LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 451 



5. Ground purple-black, not darker at middle of costa .... 43. daeckeana. 

 5. Ground brownish, with a blackish shade at middle of costa. 



42. hebesana. 

 5. Lighter dull fuscous with a vague transverse luteous band. 



40. murina. 

 2. Fore wing with some brilliant blue iridescence. 



3. With a well-defined, vertical, blue-gray bar before anal angle. 

 4. Sparsely dusted with ochre. 



5. Head light ochre 46. auricapitana. 



5. Head fuscous; only palpi paler. 



6. Fringe almost entirely dark 45. agilana. 



6. Fringe on costal half of outer margin mostly cream-white. 



47. albiciliana. 



4. Heavily dusted with cream and whitish 7. turfosana. 



3. With a large blue patch before anal angle, ground blackish . . 44. cyanana. 



0. conditana is probably confined to California : eastern records are based on 

 dwarfs of hebesa'na, and specimens of Polychrosis. 



1. 0. bipartitana Clemens. Fore tibia with faint pale bands; mid-tibia usually 

 all black, and hind tibia whitish. Palpus with more fuscous than in 0. fuscalbana. 

 Fore wing rather less than twice as long as wide; mixed dark shining blue-gray 

 and black; a white antemedial fascia, with some black scales, a sixth as wide as 

 length of wing, erect and of even width, its boundaries slightly irregular. Beyond 

 this a blackish fascia, slightly broadening toward inner margin, reaching out to 

 end of cell. The rest of wing white, shaded with gray on the apical half, more 

 or less, or with a separate gray margin and subterminal patch. Costal edge gray, 

 with paired white striae. Hind wing typically whitish, gray in variety ccesialbana 

 Zeller; fringe whitish. 10 mm. (Antithesia Clemens). 



May and June; August. 



Common everywhere. Xew York: Xorth Elba, Fentons (Lewis County), Oswego, 

 Jamestown, Rock City ( Cattaraugus County ) , Millerville, Otto, McLean, Ithaca, 

 Big Indian Valley, Albany. Ramapo. 



2. 0. fuscalbana Zeller. Fore tibia with three heavy white bands; mid-tibia with 

 two or three weaker ones; palpus heavily mottled with white. Wings slightly 

 narrower than O. bipartitana: antemedial fascia somewhat narrower, hardly more 

 than half as wide as the blackish area following it, which is more or less dusted 

 with broad yellow scales. Apical region more distinctly blackish, especially the 

 apical dot; subterminal bar conspicuously dark. 15 mm. 



June to August: common. 



Generally distributed, south to Xorth Carolina. Xew York : Peru, Xorth Twin 

 Brook (Mt. Marcy), Xewcomb, Peru, Rock City (Cattaraugus County), Ithaca, 

 Trenton Falls, Fort Edward. 



Gypsonoma fasciolana is near this species in appearance, but differs in the 

 stalking of M 3 and Cu,. the wing-form, and the narrower, decidedly oblique median 

 dark fascia, preceded by a broader and purer white antemedial fascia. Cymolomia 

 fasciatana has similar tibiae, but the palpi are almost wholly whitish; and the 

 antemedial fascia is considerably stronger than the postmedian. 



3. 0. carolana McDunnough. Tegulse white, with a dark patch at the base; 

 thorax banded with white. Blackish and olivaceous brown; antemedial white band 

 slightly irregular; subterminal white band narrow, the terminal area being broadly 

 suffused with olivaceous brown; anal spot fused in with the dark median area, 

 with a point of the white color running between them above; two olive-brown 

 costal spots, sometimes connected by hair-lines with the brown terminal area. 

 14 mm. (Xot seen.) 



June. 



Ottawa and Trenton, Ontario.
