LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 123 



closely grouped; setae i of abdomen farther apart than ii; iv and v widely sepa- 

 rated, on separate tubercles. Prolegs with uniordinal hooks, in a complete ellipse 

 or shortly interrupted on inner posterior side; the anal prolegs with a short band. 



The larvae are generally case-bearers, the case usually ending in a three-cornered 

 valve, as in the lower Coleophoridte and Psychidse; occasionally it is lenticular. 

 The larvae are often scavengers. 



Pupa only lightly soldered together; wing lanceolate; antenna extending to wing 

 tip; in Tinea, at least, with two prominent spines at the end of the abdomen. 

 Cocoon of silk, usually in the larval case. 



2. SCAEDIA Treitschke 



Antenna moderate, with pecten and with raised scale-whorls. Maxillary palpus 

 small but folded; tongue strong and naked. Palpus long, porrect, with a large 

 tuft on under side of second joint and bristles on outer side; third joint long, 

 upturned. Head rough. Wings heavy, hardly lanceolate. Fore wing sometimes 

 with R 3 and R 4 stalked, hind wing with Mj and M 2 connate; with fringe one-half 

 as wide as membrane. Hind tibia with long hair. 

 The larvae bore in fungi. 



Key to the species 

 I. Blackish, with contrasting, pale inner and outer margins. 



2. Fore wing broader 6. anatomella. 



2. Fore wing narrower; with distinct, paired, pale costal striae 5. fiskeella. 



1. Ground paler, often heavily overlaid with blackish; inner and outer margins 



not pale. 



2. A black discal bar (inconspicuous when the region about it is blackish). 

 3. Fore wing with a dark postmedial fascia, angled on outer, and erect on inner, 



side. Expanse 25 mm 1. fuscofasciella. 



3. Fore wing with the postmedial fascia rather evenly excurved. Expanse 



18 mm 2. errandella. 



2. No black discal bar. 



3. A contrasting, pale antemedial fascia between the dark basal and medial 



areas 4. pravatella. 



3. No such pale, complete band 3. approximatella. 



1. S. fiiscofasciella Chambers. Clay color, dusted and mottled with brown, with 

 more or less paired, dark costal striae; the dark postmedial fascia quite obscure 

 and concave below the angulation. 28 mm. (Euplocamus Chambers). 



This species was described from Kentucky. 



2. S. errandella Bnsck. Similar to 8. fuscofasciella, the ground more evenly 

 lutecus, the markings dull fuscous, with the usual purplish iridescence more 

 sharply contrasting. The paired costal striae distinctly pale; the darker post- 

 medial band as in 8. fuscofasciella, containing the slightly darker discal bar. 

 18 mm. (tessulatella auct., not Zeller). 



July ana August in western Pennsylvania. 



3. S. approximatella Dietz. Luteous, dusted and mottled with fuscous; the 

 dark fascia somewhat anterior to the middle; irregular on basal side, and often 

 running in below the cell to join an oblique fascia from base of costa, thus forming 

 a sort of W which is nearly erect on outer side. A subterminal dark streak 

 running to the costa before the apex. Antennal cilia long (2). 15 mm. 



' The moth occurs in July. The larva has been found in a rotting sycamore log. 

 Massachusetts to western Pennsylvania and Georgia. New York: Ithaca. 



4. S, pravatella Busck. Similar to 8. fuscofasciella, with basal third heavily 

 dusted and contrastingly dark except on inner margin. Wing narrow. 23 mm. 



Western Pennsylvania.
