Lepidoptera of New York and Neighboring States 353 



divided. In a web at tip of leaf in April, July, and August. Cocoon dense, white. 

 Ottawa, Ontario; Montreal, Quebec; Europe. A paler form occurs in Colorado. 



2. S. pariana Clerck. Similar to 8. fabriciana, but with the markings even more 

 obscure, and the white in the fringe confined to the tips of the outermost scales. 

 10 mm. 



August. Larva on apple : a leaf -toller. 

 Tarrytown, New York, introduced from Europe. 



II. Fore wing triangular with marked apex, but even and slightly convex outer 



margin; the fringe wholly and evenly fuscous. Palpi as before. R 4 and R 5 

 stalked halfway to apex (Allononyma) . 



3. S. diana Hlibner. Gray, powdery, and mottled with fuscous; with three 

 obscure, broken, and irregular transverse bands, partly defined with white. Some- 

 times distinctly greenish. 15 mm. (Hemerophila vicarialis Zeller; betuliperda 

 Dyar.) 



Larva translucent greenish yellow. Head pale reddish with a black line on 

 sides behind; tubercles black; body with a clear white dorsal, and blurred lateral 

 lines; under a web on upper side of leaf of birch; eating upper parenchyma only. 

 Cocoon fusiform, with truncate ends, under a carpet, denser than the larval web 



Nova Scotia to White Mountains, New Hampshire; west to British Columbia 

 and Utah. 



The status of this species is uncertain. The green (diana) and gray 

 (betuliperda) forms are rarely found together, but each covers the range of the 

 species. Vicarilis was described as largely light brown. I have seen no such 

 specimens and it may be stained betuliperda. Variants of both green and gray 

 forms occur in Europe. If these European types prove to be a distinct species, 

 diana will have to be used for them and vicarilis is available as the name for our 

 species. 



III. Fore wing with costa more wrched, apex rounded, outer margin evenly convex, 



more upright than before, with metallic scaling. Palpi with third joint 

 chisel-shaped, appearing pointed in side view, but as broad as second, to its 

 apex, in front view (Brenthia Clemens). 



4. S. pavonacella Clemens. Fuscous. Lower part of face pale; palpi white with 

 three fuscous rings; antennse barred above; fore wing mottled with whitish, 

 especially about the middle; a broad black terminal band, containing a streak of 

 bright iridescent scales, often broken into spots, and with a few such scales at 

 middle of costa. Hind wing fuscous, not powdery; shaded with whitish, with a 

 short metallic band near apex. 8 mm. 



May; July and August. Larva on Desmodium and Amphicarpa. The moth 

 struts about on alighting, with hind wings displayed like Glyphipteryx, the smaller 

 Anacampses, etc. 



New York and Pennsylvania to Brazil, west to Kansas. New York: Ramapo. 



3. CHOREUTIS Hiibner 



(Porpe Hiibner) 



Costa strongly arched (fig. 213), apex more or less marked; anal angle marked 

 only in C. inflatella. Hind wing rounded, the first two anal veins not closely 

 parallel. Palpi with long acute third joint; and long stiff hair-scales on the under 

 side of the second joint (fig. 216), sometimes in two slightly divergent sets. 

 Antenna? sometimes with a triangular mass of projecting scales on lower side of 

 scape.
