lated thau the first ; this ia 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 fii'st costal streak ; tliis 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 j)roceeds out- 

 wards along the middle of the wing, forming a dark patch below and beyond the 

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

 shading to pale grayish-safi"ron beyond their faintly darker median line. 



Hind wintjs and cilia, pale grayish, with a very faint safi^rou tinge. 



Abdomen, pale gray, anal tuft saftrou-yellow. 



Hind tai'si, white with two grayish-fuscous bars above.

Typeg ^Miis. Wlsm. 

 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 Vaccinium ovaia, 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. 



LithocoUetis oregoiiensis sp. u. 



AiiicntKV, closely annulate with white and brown. 



Palpi, whitish, dusted with gray externally. 



Haustellnm, yellow. 



Head, face grayish, frontal tuft grayish-fuscous. 



Thorax, golden-saffron. 



Fore wings, golden-sali'ron, with four rather shining white fasciie and a semi-circular 

 white ai^ical 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 thau 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 augulated 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, encjrcied 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 lino along their base. 



Hind xvings and cilia, pale grayish. 



Abdomen, gray. 



Hind tarsi, whitish, thickly spotted with fuscous above.

Type 5 Mus. Wlsm. 

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



northern Oregon, in April, 1872. 



A beautiful and distinct species, somewhat allied to the Euroi>ean scabiosvUa. I 



have unfortunately no knowledge of its food-plant. 



LithocoUetis insignia sp. n. 



Antenna', yellowish, unspotted. 



Palpi, white. 



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