4. Tip of antenna black 5. pulchrimella. 



4. Tip of antenna white 6. magophila. 



3. Inner margin not edged with white. 



4. Outer silver fascia of two obliquely placed vertical bars 



4. gemmiferella. 



4. Outer silver fascia oblique, continuous 3. clemensella. 



2. Lines extending out to middle of wing; ground light brown. 



3. Expanse usually under 8 mm.; apex of antenna white 2. delicatella. 



3. Expanse usually full 10 mm.; apex of antenna black 1. fernaldella. 



1. Fore wing with a double silver spot at one-fourth way out; but no lines. 



7. clandestinella. 



1. C. fernaldella Walsingham. Light brown. Head and thorax with three fine 

 white lines; antenna? outwardly dark, with the fourth and tenth segments from 

 apex white, and sometimes other isolated segments also. Fore wing with costal 

 edge, at basal third, and dorsal edge, toward base, finely white; three white streaks 

 on disc, the first running from costa, well out from base, and the lower reaching 

 middle of wing. A yellow fascia covering third fifth of wing, bounded on each side 

 with two silvery bars; the upper, inner one followed by a black spot; the outer two 

 separated by a longitudinal yellow streak, which becomes white outwardly, is edged 

 with dark brown, and runs through the fringe to the extreme apex. 8—10 mm. 

 (floridanella Beutenmuller, nigripunctella Busck.) 



Southern States; New Jersey; Ottawa, Ontario. 



2. C. delicatella Walsingham. Similar. Antennas with last four segments white, 

 and normally also the sixth and tenth from apex. Fore wing with yellow fascia 

 broader than in C. fernaldella; the upper anterior silver bar located farther toward 

 the base; and the following black dot small, the yellow extending basally below the 

 bar and touching the lower white streak. 8 mm. 



Southern States, north to District of Columbia. 



3. C. clemensella Stainton. Very similar to C. gemmiferella; ground of fore wing 

 darker, orange fascia paler, less reddish, its bordering fascia pale golden rather than 

 violet, the more apical one oblique and continuous. Antenna? with apex broadly 

 white, and a broad white area about three-fourths way out, sometimes interrupted 

 by a couple of black rings. 



Larva on Ipomoea. 



Massachusetts to Virginia and western Pennsylvania; "New York" (United 

 States National Museum). 



4. C. gemmiferella Clemens. Antenna? with apical three or four segments white, 

 then four black ones, and one or two narrow white bands. Fore wing and thorax 

 dark greenish brown; three longitudinal white lines on body; fore wing with three 

 short white streaks at a fourth way out, the upper resting on the costa; and no 

 white on inner margin; a broad orange fascia rather beyond the middle, with a 

 large, oval, violet-silvery fascia before it, extending almost across the wing, and two 

 separate spots beyond, the upper offset outward about its width and edged above 

 with white; all the silver spots partly edged with black; a long silvery streak in 

 apical fringe, starting from a silver-blue apical dot. 11 mm. 



June and July. Larva a miner in Ipomoea. 



New York to Texas. New York: Sea Cliff, Long Island (Busck). 

 C. hermodora Meyrick (Exotic Mierolepidoptera ii, 282) must be closely similar, 

 but with one broad subapical band on the antenna?. 



5. C. pulchrimella Chambers. Antenna? outwardly black, with fourth apical joint 

 white, and a second group of two or three white rings at three-fourths its length. 

 Fore wing much like C. gemmiferella; inner margin very narrowly white at base, 

 yellow band duller and shading into brown toward base, rarely chocolate brown ; 

 silver fascia? bluish, the outer one continuous, oblique, starting from a white costal 

 streak; apical white streak not reaching halfway in to the apical blue dot. 8 mm.
