624 WILLIAM T. M. FORBES 



1. T. finitella Walker. Dark powdery gray, somewhat brownish; antemedial 

 line raised, blackish, obscure; tuft heavy, blackish; a series of small median 

 blackish tufts; discal dots black and tending to be confluent; postmedial line 

 normal, pale, denned with dark, not conspicuous. A broken black terminal line 

 as usual. Tuft on antenna very large, much more than filling the notch. 25 mm. 



May. 



Nova Scotia to Florida and Colorado. 



2. T. reductella Walker. Wings pale gray, in part often almost white; post- 

 medial line slightly paler, normal, dentate, defined by slightly darker gray on outer 

 side. Base of wing and thorax brown (in variety gleditschiella Fernald, mouse 

 gray); the tuft black, and not strong. Antemedial line heavy, black, outwardly 

 oblique, and a little wavy, preceded by a pale line; discal dots black; no raised 

 median tufts. 22 mm. 



The larva webs together leaves of Gleditschia in September, emerging in late 

 fall or the following May. Cocoon in rubbish on the ground. 

 New York to Ohio. New York : New Windsor. 



85. MEROPTERA Grote 



Like Salebria, our species with R 2 stalked, M 2 and M 3 clearly stalked; wings 

 smooth-scaled. 



1. M. pravella Grote. Ash gray, base contrastingly pale gray, with an even, 

 slightly oblique outer boundary, followed by a strong blackish shade. Basal angle 

 reddish. Discal dots blackish, tending to fuse, in a paler area; postmedial line 

 pale, defined with darker gray, distinct but not contrasting. Terminal line con- 

 tinuous, black, weak. 20 mm. 



March to May. The larva is said to be brown, with dorsal and lateral green 

 lines, plain brown cervical shield, and head green, brown, or reticulate with black; 

 in a web between two leaves of willow, or on Rhus Cotinus, in September. 



Maine to British Columbia and Texas. New York: Lancaster, and New Windsor. 



2. M. unicolorella Hulst. Mouse gray, slightly violaceous; markings obscure, but 

 normal so far as traceable; antemedial line darker; postmedial paler, both diffuse. 

 22 mm. 



Late May to August. 



Montreal, Canada, to Florida and Texas (not Washington, as stated by Ragonot). 

 New York: Ithaca. 



3. M. uvinella Ragonot, as described, is paler than M. pravella, with the post- 

 medial line white, clear, and straighter in the middle part. 16 mm. 



United States. 



Probably a mere variant of M. pravella. M. cviatella Dyar appears to be a 

 Salebria. 



86. SALEBRIA Zeller 



(Meroptera, in part; with Pempelia) 



Similar to Nephopteryx. Maxillary palpi yellow, plume-like, enclosed in a 

 groove in the second joint of the upturned labial palpi. Fore wing normal; hind 

 wing (fig. 381) with moderate cell, Cu, apparently from angle. Wings smooth 

 in our species. Antenna? in our species smooth beyond the tuft. 



Key to the species 



1. Antemedial line followed by a pale patch on inner margin (obscure in some 

 specimens of contatella) . 



2. Wholly blackish otherwise 3. engeli. 



2. Basal area contrastingly darker gray, at least toward the inner margin. 



2. annulosella:
