.">. S. fiskeella Busck. This species is distinguished from fuscofasciella and prava- 

 trlla by the luck of transverse bands, from anatomella by the narrow wings and 

 the tendency for the pale outer margin to widen more opposite the cell. 25 mm. 



North Carolina. 



i. S. anatomella (Jrote. Dull black, reticulate and mottled with intense black; 

 discal bars light. Slight pale spots on costa; outer and inner margins very irregu- 

 larly edged with a contrastingly pale, clay-colored area, dusted with dark fuscous, 

 and sometimes broken into spots. 2f> to over 30 mm. 



The moth occurs in June and July in western Pennsylvania and is also known 

 from western Ontario. Diet/, records it from Xew York. 



3. ELATOBIA. Herrich-Schaeffer 

 (Abacobia Dietz, not Lacordaire; Dietzia Busck) 



Similar to Tinea; M, and M.. of hind wing stalked; tongue and maxillary palpus 

 smaller than usual but not absent. Antenna half as long as fore wing, with 

 pec-ten. Hind wing as wide as fore wing. Palpus with second joint clavate, third 

 with some bristles. Female ovipositor membranous. 



Larva dirty white, with reddish head and anal plate and blackish cervical shield 

 and tubercles; boring in the bark of pine in early spring. 



1. E. fuliginosella Zeller. Dark fuscous brown; hairs of head and palpi white- 

 tipped; discal spots darker. Hind wing paler. 14-19 mm. (martinella Walker, 

 carbonella Dietz). 



The moth occurs in July. 



Haxleton, Pennsylvania; Hudson Bay district; Colorado; Europe. 



4. TINEA Linnaeus 



Small moths, the largest hardly an inch in expanse. Palpus smallish, smooth- 

 scaled, and more or less distinctly bristled on outer side, occasionally with some 

 spatulate scales. Head, including front, with rotigh, bristling hair, often con- 

 trastingly colored. Maxillary palpus and tongue developed; 'antenna with whorls 

 of raised scales and pecten. Hind tibia with spurs above middle. All veins free. 

 Base of M more or less distinct; M.. and M 3 of hind wing stalked in T. rileyi. Hind 

 wing lanceolate, about as wide as fore wing. 



Argyresthia may be distinguished by the smoother face, and by R 5 running to 

 outer margin ; Acrolepia, by the much smoother head. 



In the following key I have only l>een able to include the species known to me 

 personally, and a few others of striking character. Inere are a good many other 

 described forms, some ot which may not be valid. 



Key to the species 



1. Hind wing (fig. 73) as broad as fore wing; subcosta extending three-fourths 

 its length or more, and cubital branches long, except in a few species 

 with yellowish head and simply marked fore wings; costa not sinuous. 



2. Head dull ochre to fuscous. Fore wing usually nearly concolorous. or if 



blackish, strongly mottled, and with dark discal dots (obscure in the 

 dark form of T. ca-mariella ) . 

 3. Eyes narrower than the distance between them below. 



4. Eyes very small, half as wide as the distance between them ; fore wing 



obscurely mottled in two shades of fuscous 2. obscurostrigella. 



4. Eyes two- thirds as wide as the space between them; mottling contrasting, 



blackish on luteous 1 . m isella. 



3. Eyes wider than the space between them below. 



4. Ground even, shining; each scale dark-tipped; discal dots distinct. 



10. pellionella. 



4. Fore wing mottled, with blackish scales in groups, or with scattered, con- 

 trasting, dark scales, at least toward apex. 

 5. A blackish longitudinal streak from base to apex 4. apicimaculella.
