slate. Subterminal white line is indicated by scattered white scales, 

 more definite near costa. Terminal line black. Fringe pale slate, check- 

 ered with black opposite veins and having at base a whitish line. 

 Secondaries with powdery surface as in primaries. The geminate cross 

 lines clearer at inner margin, almost disappear costally. Intradiscal 

 runs straight across wing, including the small black distinct discal dot. 

 The extra discal parallel to outer margin, in other respects similar to 

 primaries. Beneath sprinkled with dark brown and clear white scales, 

 the pattern as above, on all wings strongly reproduced. The extra 

 discal on all wings bordered internally and externally, with a darker 

 narrow line of brown, and the sharply distinct, somewhat linear discal 

 dots are black. Body, legs, and abdomen beneath with white and brown 

 scales mixed, the latter predominating at tip of abdomen. 



Types Male and female were taken at Chimney Gulch, 

 Golden, Colo. (Oslar), V, 22, 08; also a cotype female; all in 

 author's collection. 



This is the species associated by Doctor Hulst in his collec- 

 tion at New Brunswick with the true type of Eup. subcolorata. 

 The specimen is in very poor condition, but its strongly marked 

 underside probably led him to believe it the same. 



Eupithecia conceptata, new species. 



Expanse, 18 to 20 mm. 



Palpi moderate bushy brown, tipped with white. Antennae in male 

 liiciliate, finely serrate, with a small fascicle of fine hair springing from 

 each tooth, in female simple strongly ciliate, as much so as is the male 

 in many species. Wings narrow, produced at apices. Front yellowish- 

 brown. Beneath antennae a small jet black spot and below these at 

 orbits a white spot which apparently may join in an indefinite band 

 across front, or may be entirely absent. Collar and vertex paler. 

 Thorax with a broad band of dark brown across front, yellowish- 

 brown of russet centrally, paler posteriorly. Abdomen with first and 

 second segments nearly white, remainder with row of broken black 

 spots on either side of dorsum, producing a pale line centrally, its 

 general color a brownish gray. No tufts apparent. Primaries, ground- 

 color yellowish-brown, darkened basally and subterminally by a mix- 

 ture of dark brown and black scales, these in the female frosted witli 

 white, producing a grayish look. Within extra discal, along vein 1, the 

 median vein, and subcostally, occasionally to outer margin along vein 6, 

 strongly tinged with russet. A decided dusky spot from angle of extra 

 discal along costa to apex. The pale geminate cross-lines are outlined 

 with black hair-lines, the basal narrow and lost in darker basal area. 

 Intradiscal, nearly one-third out, makes a sharp outward angle below 

 costa, another between veins 1 and 2, and touches inner margin one-half 

 out. Another black hair-line, heavier at costa, passes outward just be\oml
