if era. This need not result in confusion of the two species, as 

 C. granifera emerges almost three months earlier. The case 

 of C. duplicis is almost identical with that of C. crlcoidcs on 

 another species of Aster, but besides differences in color and 

 markings C. crlcoidcs is much more slender and narrow- 

 winged. 



Coleophora biforis n. sp. 



Head pale grayish ocherous ; palpi whitish, apical half of second 

 segment blackish outwardly; lower edge of third black. Antennae with 

 basal segment thickened with scales, stalk white, with conspicuous 

 dark brown annulations. 



Fore wings pale grayish ocherous, marked with whitish lines as fol- 

 lows : A distinct white streak from base along costa for about one- 

 half the wing length a distinct rather broad white streak from base 

 along upper margin of cell, forking at one-third, the upper fork a 

 continuation of the broad white streak and running out to the middle 

 of costa, the lower fork continuing through the middle of the cell as 

 a very indistinct whitish line, which at the end of the cell bends up to 

 reach costa near apex. Sometimes at the bend it sends a branch to 

 termen. Between the ends of the forks, two short usually detached 

 whitish lines run to costa (sometimes these are branches of an indis- 

 tinct line along upper margin of cell) ; narrow whitish lines along fold 

 and along dorsum. Usually the white streak along costa and the white 

 streak along upper margin of cell to middle of costa are the only dis- 

 tinct white streaks. Extreme base of costa blackish. Hind wings 

 pale gray, cilia toward apex ocherous-tinged. Legs pale grayish 

 ocherous. Alar expanse: 11.5-12.5 mm. 



Type ( $ ) and five paratypes reared from larvae mining 

 into seed pods of Lnziila catnpestris, Cincinnati, Ohio. Type 

 and paratypes in the writer's collection. 



The cases may be found attached to the seed pods in April 

 and May ; the moths emerge the following spring at the time 

 of blooming of the food plant. The completed case measures 

 8-8.5 mm. in length, slender cylindrical, tapering to the three- 

 valved apex. The sides of the obtuse apical angles of the 

 valves are very short; from the point of union of adjacent 

 valves, a gradually lowering ridge runs about half-way down 

 the case.
