with the whitish costal cilia. White streaks usually indistinct and in- 

 terrupted mark the course of the veins; of these the most distinguish- 

 able are along veins n and 10 and along the upper margin of the cell. 

 A faint narrow line runs for half the wing length above the fold and 

 parallel to it; another short line lies 'just below and alongside of the 

 fold. A short streak sometimes runs through the outer half of the 

 cell. The dorsal margin is narrowly white. Dorsal cilia concolorous 

 with the wing. Hind wings grayish ocherous. Legs whitish, with 

 the outer surfaces marked with brown. Expanse : 12 mm. 



Locality : Cincinnati, Ohio. Type and six paratypes in 

 writer's collection. 



The larva mines the seeds and receptacle of a wild white 

 aster (Aster ericoidcs L.). Numhers of the small seeds of 

 the flower heads may be found eaten out presumably by the 

 larva before making a case, or while the case is still very small. 

 Later the mature case is attached to the surface of the re- 

 ceptacle and the larva mines into it, eating out the pithy cen- 

 tral portion ; one or two circular holes mark the point of en- 

 trance. The mature case is short, cylindrical, with three-valved 

 apex, measuring 4.5 to 5 mm. in length, with a greatest diame- 

 ter of 1.3 mm. The case is spun entirely of silk, in color vary- 

 ing from pale straw to brownish cinereous ; it is more or less 

 densely covered with pappus from the flowers, attached ir- 

 regularly over the surface and extending backwards beyond 

 the apex. It is thus difficult to discern in the ripening seed- 

 head. The larvae are fully fed in the latter part of Novem- 

 ber and early in December may be found crawling or attached 

 to stems and sticks in the neighborhood. The moths emerged 

 September 17 to 28. 



Coleophora amaranthella n. sp. 



Head pale dull ocherous, palpi whitish, apex and projecting tuft of 

 second segment fuscous. Antennae whitish, annulate indistinctly with 

 brownish ocherous. Thorax whitish dull ocherous. 



Fore wings pale brownish ocherous, the spaces between the veins 

 reaching the costal edge white, more or less densely dusted with fus- 

 cous ; beneath the apex the ground color is irregularly sprinkled with 

 white and fuscous scales. A white dusted streak extends through the 

 cell, starting faintly near the base and broadening outwardly and ends 

 at the lower angle of the cell in a rather conspicuous fuscous spot. A 

 dusted white streak along the fold and another along the dorsal mar- 

 gin. Hind wings pale grayish ocherous. Legs whitish with a fuscous
