lated than the first ; this is also slenderly dark-margined internally and more 

 widely so externally, the black dusting on its outer side being produced back- 

 wards at the angle in the direction of the first costal streak ; this is at the com- 

 mencement of the costal cilia, -rather further from the base than the first dorsal 

 streak, which is oblique, its point terminating below the point of the first costal 

 streak ; from the points of these two streaks a cloud of black scales proceeds out- 

 wards along the middle of the wing, forming a dark j>atch below and beyond the 

 second costal streak which is situated just before the apex; the cilia are saffron, 

 shading to pale grayish -saffron beyond their faintly darker median line. 



Hind wings and cilia, pale grayish, with a very faint saffron tinge. 



Abdomen, pale gray, anal tuft saffron-yellow. 



Hind tarsi,- white with two grayish-fuscous bars above.

 The puckered mines of this species were found in some abundance in June, 1871, 



in Mendocino County, California, on the upper sides of leaves of Vaednium ovata, the 



mine occupying the whole surface of each leaf and causing the margins to approach 



each other. I took the species also on the wing at the same time and place. This 



species belong to the same group as cincinnatiella Chamb. 



Lithocolletis oregonensis sp. n. 



Antenvw, closely annulate with white and brown. 



Palpi, whitish, dusted with gray externally. 



Hanstellum, yellow. 



Head, face grayish, frontal tuft grayish-fuscous. 



Thorax, golden-saffron. 



Fore wings, golden-saffron, with four rather shining white fascia? and a semi-circular 

 white apical streak inclosing a black apical spot and reaching through the cilia 

 on the costal and dorsal margins; the first fascia is situated within one-fourth 

 the wing-length, the dorsal portion of it commencing nearer to the base than the 

 costal portion and proceeding obliquely outward to a little above the fold, the 

 shorter costal portion only being conspicuously dark margined internally; the 

 second fascia, just before the middle, is distinctly curved, almost angulated out" 

 wards, and has a conspicuous margin of black scales on its inner side; the third 

 fascia, commencing before the costal cilia, is less curved than the second, but 

 its black inner margin interrupts it in the middle by a short line of black scales; 

 the fourth fascia, at the apical fifth of the wing, is also internally black-margined, 

 but the black scaling is almost interrupted, becoming very slender at the middle of 

 the wings ; the apical spot is black, encircled by white as already described ; the 

 cilia are grayish, tinged with fuscous about the anal angle, and with a short 

 golden-saffron dash from the black apical spot; there is no line along their base. 



Hind icings and cilia, pale grayish. 



Abdomen, gray. 



flind tarsi, whitish, thickly spotted with fuscous above. 



Exp. al. 7 mm . 



Type 2 Mns. Wlsm. 

 Two specimens taken on the wing near Fort The Dalles, on the Columbia Eiver, in 



northern Oregon, in April, 1872. 



A beautiful and distinct species, somewhat allied to the European scabiosella. I 



have unfortunately no knowledge of its food-plant. 



Lithocolletis insignia sp. n. 



Antenna", yellowish, unspotted. 



Palpi, white. 



Head, face white, frontal tuft white with a few saffron scales. 



Thorax, white.
