LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 409 



Easily distinguished by the peculiar form of the basal patch, and lack of yellow 

 coloring. 



3. A. semiovana Zeller. Markings gray-brown with a slight golden iridescence, 

 on a white ground. Dorsal patch large, extending two -thirds way out on inner 

 margin, evenly rounded, and followed by a white fascia. Outer half brown, from 

 middle of costa and from about three -fourths way out on inner margin; a large 

 trape/oidal white costal fascia at two-thirds way to apex, containing a very slight 

 brown costal stria; the costal striae following it not distinctly in pairs. Speculum 

 not distinct. Fringe contrasting, pale. 13 mm. 



May and June. 



Canada to North Carolina. New York : Ithaca. 



4. A. maritima Dyar. Clay-color, with a slight olivaceous tint, the markings 

 edged with white. Dorsal patch long and narrow, the outer side strongly oblique, 

 and ending at the tip of the anal vein, where the spot shades into the ground. 

 Costal end of median fascia clearly denned, and lower end denned by a curved white 

 line; the fascia longitudinal in general course near middle of wing; the two black 

 dashes in the outer angle of the fascia distinct. Costal striae normal; apex 

 dark; fringe concolorous. Hind wing mouse gray. 10-12 mm. 



Larva in summer on beach pea; moth the following spring and again in August. 

 The species will probably occur generally along the coast. 

 Kennebunkport, Maine, to Speonk, New York. 



5. A. pulchellana Clemens. Ground whitish, shaded with light fawn; median 

 fascia hardly darker, clearly denned on outer side by a silver-white line which 

 forms a sharp angle opposite the notch; where it contains a couple of obscure 

 brown dashes. Costal striae fine, silvery, defining slightly darker yellow-brown 

 bars. Speculum typically represented by a dark dot. Apex yellow -brown; dorsal 

 patch yellow-brown, large and rounded. 13 mm. 



May to July. 



Massachusetts to Virginia and Illinois. New York : Ithaca. 



6. A. angulifasciana Zeller. Ground dull luteous; dorsal patch and fascia blackish, 

 the former rather short and wide, ending rather squarely on inner margin ; the 

 fascia broad, defined on outer side with an angulate dull silver line, with a couple 

 of black dashes in the angle. Costa outwardly with irregular pale and dark short 

 striae, the ground of the whole outer part brown, but paler than the fascia. 8 mm. 



May to July; late August. Larva on clover. 



I have seen this species confused with A. floridana, from which it can be readily 

 distinguished by the contrasting pale costa. It is easily recognized by its small 

 size and heavy, sharply contrasting markings. 



Generally distributed and not rare, westward to Illinois and Manitoba. New 

 York: Crosby (Yates County), Ithaca. 



7. A. platanana Clemens. Ground cream-white, including thorax and whole 

 base of wing. Dorsal patch defined only on its outer half, which is rusty ochre. 

 Median fascia ochre, often interrupted by the cream-white ground, below costa; 

 with two or three heavy black dashes in the angle, and often another in the 

 speculum, which is more or less suffused with ochre. Costal striae light ochre, in 

 a cream-white area; all the markings tending to become diffuse. 10 mm. 



Other specimens are larger and more diffuse in markings, with the dorsal patch 

 almost completely lost, and with the black striae lighter. They may belong to 

 A. platanana, but I suspect they are suffused forms of the burgessiana group. 



June. 



Apparently general in distribution. New York : Rock City ( Cattaraugus County ) , 

 Big Indian Valley, New Windsor. 



The remaining names have been used more or less interchangeably for specimens 

 in which the basal patch is well defined, of moderate size, and varying from yellow- 

 brown to black in color; the fascia yellow-brown, usually markedly paler than the 

 basal patch, defined on the outer side by an angulate silver or gray line, and con-
