Lepidoptera op New York and Neighboring States 539 



Fore wing with obscure dark ante- and postmedial lines, running about as usual; 

 slight gray shades before antemedial line and beyond postmedial. Discal dot 

 black, strong; one or two black terminal dots near apex. Hind wing white, with 

 a small gray subterminal shade near the black tufts. 15 mm. (Sym/physa 

 Kearf ott. ) 



Late July and early August. Larva in a flat oblong case; constricted near each 

 end; on lichens. 



Anglesea, New Jersey. ■ 



4. L. sicalis Walker. Palpi oblique, maxillary palpi very small ; tufts strong. 

 Fore wing cream-white, shaded with clay color in outer part, leaving some white 

 along postmedial line and on margin; medial area largely clay-color, more or less 

 suffused with fuscous, but leaving the region beyond the cell pale. Lines fine and 

 dark; postmedial line, when complete, with a long tooth in the fold running up 

 toward the lower angle of the cell. Hind wing similar, with a distinct black post- 

 medial line; median area dusted with black, usually leaving a distinct white discal 

 dot. 18 mm. 



May to July. 



New York to Illinois, Iowa, and Texas. "New York" (American Museum of 

 Natural History.) 



5. L. fuliginosalis Fernali. Maxillary palpi distinct, labial palpi oblique; tufts 

 on hind wing strong, whitish, heavily shaded with fuscous, leaving only the base half- 

 way out to the antemedial line, apex, and sometimes outer part of costa and outer 

 margin, white; lines blackish as before, usually with broken terminal line. Hind 

 wing normally with blackisih below the end of the cell to the inner margin, and a 

 marginal shade toward inner margin; sometimes mostly fuscous. 12 mm. 



June and September. 



Southern New Hampshire to Michigan, south to New Jersey and Missouri. 

 New York: Otto. 



17. DICYMOLOMIA Zeller 



Venation as in Lipccosma; tufts on upper side of hind wing strong; labial palpi 

 upturned (fig. 318), with more or less rough hair, as in Lipocosma; maxillary 

 palpi decidedly longer than third joint of labials, rough-scaled, and truncate. Hind 

 wing more or less distinctly notched opposite cell, with brilliant metallic scaling 

 along outer margin below the notch. 



Larva (fig. 319) with setae vii on meso- and metathorax single; prolegs with 

 crotchets biordinal; in a circle, shortly open on the outer side. Seta v of abdomen 

 directly above iv; the tubercles much reduced; a single lateral seta on segment 9. 



This genus, and the related western Chalcoela, have generally been put in the 

 Crambinse, but they are very closely related to Glaphyria and Lipocosma in every 

 way. The larva also appears to be near that of the Pyraustinae, but wholly unlike 

 the Crambinae. 



Key to the- species 



A single row of black dots on outer margin of hind wing 1. julianalis. 



Two rows of alternate black dots 2. pegasalis. 



1. D. julianalis Walker. Light brown, shading into bright yellow at the base; 

 median area white, dusted and suffused with fuscous brown; lines white, rather 

 obscure, except as a definition of the median area; running as in Glaphyria; discal 

 lunule white, followed by black dusting; some white before terminal line; fringe 

 brown. Hind wing similar on inner half; median area dusted with black; with 

 two strong raised tufts; the basal and costal portion shading into white. A bril- 

 liant lead-colored marginal line below the notch opposite the cell, cut by four black 

 dots in interspaces. 15-18 mm. (decora Zeller.) 



Late June and August. Larva in cat-tail heads; stout and unicolorous whitish, 

 with dark head.
