taining a couple of gray streaks in the angle; the costal striae all paired, tine 

 and short, on a yellow-brown ground, much darker than the whitish basal half 

 of the .costa. The specular region is yellow-brown or yellow, and is darker than 

 the region just beyond the dorsal patch, but not sharply set off either from it or 

 from the lower end of the costal fascia. The apex is a little darker, the fringe 

 a little paler and duller brown. The hind wing is pale fuscous. I suspect that 

 only one species, with a tendency to form numerous local strains, is represented 

 in this series, but give the points of distinction as noted by their describers. 



8. A. spiraeifoliana Clemens. This is the oldest name of the series. As described, 

 the fascia is slightly paler than the dorsal patch, both, however, being dark brown. 

 The patch hardly enters the cell, and its outer boundary is but slightly sinuous. 

 Larva on Spircea opulifoUa, folding a leaf longitudinally and living on the paren- 

 chyma within the fold. 



Described from Pennsylvania. 



9. A. burgessiana Zeller. Dorsal patch broad, variable in shape, brown, with 

 some golden gloss. Median fascia dark rusty brown, the whitish area before it 

 more or less dusted with gray. Outer part of wing rusty. Hind wing typically 

 blackish; nearly white in var. pruni Heinrich. 15 mm. 



Type locality, Massachusetts. June and July. Larvae on oak and plum (pruni). 

 New York : Rock City ( Cattaraugus County ) , Ithaca, McLean, and Karner. 

 Generally identified with murtfeldtiana. 



10. A. murtfeldtiana Riley. Small. Dorsal path black-brown; median fascia 

 yellower, reaching inner margin (though much paler below and diffuse on inner 

 side), followed the whole distance by a whitish line, which is waved toward the 

 inner margin. Speculum usually with a heavy black dash, preceded by a lead- 

 gray patch in the fascia. 12 mm. 



May. Larva on oak. 



Described from Missouri. 



A. metamelana Walker is considered a synonym of spirceifoliona, by Fernald. 

 The dorsal patch is blackish, the fascia red-brown, apparently not reaching the 

 inner margin. 17 mm. Type locality unknown. 



A. discoferana Walker. Dorsal patch and fascia both brown, costal striae black. 

 This is also considered a synonym of spiraeifoliana, but the dark coloring and 

 small size (10 mm.) suggest rather angulifasoiana. 



11. A. laciniana Zeller. Patch and median fascia both ochre yellow, the wing 

 toward apex heavily shaded with ochre yellow; with distinct black dashes in the 

 angle of the fascia and some black scales in the speculum. 15 mm. 



Described from Massachusetts. 



This form seems identical with the following: 



A. dubiana Clemens. Cream white, with all markings ochre yellow except the 

 two black dashes. 



This form was described from Virginia. I have seen similar specimens from 

 Pennsylvania, Ohio, and elsewhere. 



12. A. fuscociliana Clemens. Ground cream to light ochre; paler toward base 

 of costa; dorsal patch large and rounded. Fascia hardly darker on costa, quite 

 concolorous below, and shading into the ground color; defined on outer side with 

 an angulate gray line, formed by the fusion of the first two costal striae. Black 

 dashes in angulation of median fascia strong. Inner margin generally suffused 

 with dull brown beyond the patch; this suffusion slight in some females. Fringe 

 brown, duller than ground color. 16 mm. 



June. Larva on chestnut and elm. 



Generally distributed and not rare. New York: Rock City (Cattaraugus 

 County), Crosby (Yates County), Ithaca, McLean, Trenton Falls. 



This is hardly more than a guhvariety of burgeseicma, but appears to have a 

 different range of food-plants.
