LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 133 



III. Fore wing with end of cell and fovea well before middle of icing; R< and R 5 

 and Cu 2 long-stalked, Mj and M, of hind wing long-stalked; valves of male rounded 

 oval (Monopis). 



8. M. rusticella Hiibner. Almost evenly mottled with purplish fuscous; fovea 

 pale. Head whitish yellow. 14-20 mm. 



The moth has apparently been introduced in the New World, and occurs only 

 sporadically in our territory. It flies from May to midsummer, and again in 

 autumn, having two broods. 



Eurasia, Truro, Nova Scotia; Toronto; Hampton, New Hampshire. New York: 

 Ithaca (probably introduced). 



7. TINEOLA Herrich-Schffiffer 

 (Tinea, in part) 



Moth similar to Tinea but with rudimentary tongue and maxillary palpi. Pecten 

 present. Eyes of male very large. 



There is a rudiment of the stigma of Trichophaga, the genus to which this seems 

 most nearly related. It comes from the old-world tropics. 



1. T. bisselliella Hummel (the clothes moth). Pale straw yellow, head more 

 rusty. Fore wing occasionally with dark outer discal dot. 12-15 mm. (lanariella 

 Clemens). (H. p. 432 f. 252.) 



The larva of this species is the commonest of the clothes moths, and is white 

 with a brown head. It forms slight silken galleries, but lives nearly free. It 

 pupates in a translucent cocoon. It will eat wool, fur, insect specimens and occa- 

 sionally other dried animal substances, but avoids cotton. 



Common and general in distribution. New York: common everywhere. 



8. TENAGA Clemens 



Eyes very small with a naked space all around. Antennae nearly as long as 

 fore wing; palpi nearly concealed in the rough facial hair. No maxillary palpi 

 or tongue. Fore wing ovate-lanceolate; cell narrow, below middle of wing; one 

 radial lost; R, and Rr, stalked, Mj and M, stalked, but free from R 4 and R 5 ; acces- 

 sory and discal cells weakly closed outwardly. Hind wing lanceolate without well- 

 marked cell. Sc ending about two-thirds way out, but costa not sinuate; M, and 

 M 2 stalked; M 3 free; Cu : angulate where the discocellular vein usually is attached; 

 fringe wider than the membrane; anals reduced. 



This genus apparently is related to Tineola. 



1. T. pomiliella, Clemens. Yellowish ochreous, with three, irregular, broken, 

 brown fasciae and scattered spots. 10 mm. 



June, August, and September. 



Southern Ohio; Pennsylvania. 



9. ISOCORYPHA Dietz 

 (Incurvaria Clemens, in part) 



Similar to Diachorisia. Antenna smooth-scaled, with a single whorl to a seg- 

 ment. Fore wing (fig. 84) smooth-scaled and slightly shining; R 4 and R 6 short- 

 stalked, and A simple. Hind wing three-fifths as wide, with Cu 2 two-thirds as 

 long as its width; and costa not sinuate. All veins separate; anals traceable. 



I. mediostriatella Clemens. Antenna nearly as long as fore wing. Head yellow. 

 Shining brown; a large golden yellow patch two-thirds way out on costa; a broad 

 streak through middle of wing, almost or quite connecting with it, and half as 

 wide as the wing; and a patch at beginning of dorsal fringe, usually joining the 

 streak. Hind wing dark. Ccsta slightly sinuous beyond middle. 8 mm. 



July to September. 



Superficially, this form is extremely close to Hybroma chrysocomella, but it has 

 a brown thorax and paler antennae, besides the venational difference.
