tinct species not closely allied to any of our known Tinese. In 

 general appearance it resembles, perhaps most, Isocoryp ha mediostri- 

 atella; in a minor degree Tinea bimaculel a, and to judge from the 

 description, seems to have a suspicious close resemblance to the 

 European Relicinella H. S., though much smaller. 



Oregonella Group. 



A small number of species are included in this group, which is 

 characterized by the wing markings, consisting predominantly of 

 longitudinal streaks or lines. The forewings are elongate. Hind- 

 wings not as wide as the former, with the costa distinctly emargi- 

 nate beyond the middle. 



The species are distinguished as follows : 



Forewings white, markings dark ; veins 4 and 5 of hindwing free. 



Costal spot not extending into disc roburella. 



Two longitudinal streaks through the disc oregonella. 



Numerous longitudinal lines mull ist riatella. 



Forewings dark brown ; veins 4 and 5 of hind wings stemmed Kileyi. 



T. roburella n. sp. — PI. II, fig. 3. — Palpi yellowish white, labials dark 

 brown externally, except at the apex, second joint roughened beneath, with dark 

 brown scales. Head sordid white, with a fuscous spot on the vertex. Antenna? 

 robust (%>), somewhat flattened, sordid white and dotted with fuscous above. 

 Thorax sordid white, speckled with, and patagia anteriorly, fuscous. Forewings 

 moderately elongate, whitish, suffused with pale brown from before the middle, 

 with dark, seal-brown marginal spots and several longitudinal streaks, a spot at 

 base of costa, a small oblique one at one-fuurth, a large quadrate spot about mid- 

 dle of costa, extending into the disc and sending a prolongation, both towards the 

 base and towards the apex, the latter extends as a streak, becoming wider out- 

 wardly and connects with the costal spot immediately before the apex ; beyond 

 the large median spot are four spots, alternately large and small, and immedi- 

 ately before the apex two connected spots, a spot at middle of dorsal margin, the 

 latter along base of cilia is dark brown, more or less interrupted ; an undulating 

 streak, which commences below middle of fold and extends towards the apex, 

 which, however, it does not attain, basal part of wing and the space below the 

 undulating streak is faintly irrorated with pale brown. Cilia whitish, with 

 rather wide dividing line about their middle, speckled and barred with brown 

 correspondingly to marginal markings. Hindwings under 1, costa distinctly 

 emarginate, grayish fuscous; cilia gray, with a sprinkling of fuscous scales. 

 Underside of wings browu. Abdomen above fuscous; body beneath and legs 

 ochreous white ; tibisB externally and tsrsal joints above, except at apex, fuscous. 



Exp. 13.0 mm. ; 0.42 inch. 



Hab. — New Jersey (Essex County). A male specimen in my 

 :ollection, kindly given me by Mr. W. D. Kearfott.
