July. The larva a blotch miner on Onosmodium, of the family Boraginacese. 



District of Columbia to California. 



C. A. quinquestrigella Chambers. Palpi white, second segment with a large, tri- 

 angular tuft, like that of Coriscium; two dark rings on the third. Fore wing 

 fuscous brown; inner margin narrowly and evenly white, with some dark scales, 

 running out at anal angle; with paired, whitish streaks running obliquely out 

 from costa and from upper edge of the dorsal streak, the outermost ones in the 

 base of the fringe, and meeting at a right angle over the apex; these streaks 

 are slightly edged with darker brown, and have dark streaks between them. 

 5 mm. (rhombiferellum Frey and Boll). 



Kentucky; Texas. 



7. A. albinotella Chambers. Head, palpi, antennae, and fore wing silvery white; 

 antennae annulate with brown ; palpus with second joint tufted, brown-gray, with 

 white tip. Fore wing shining, light olive brown; thorax with a silvery, central band 

 continued as a band on the inner margin of the wing, gradually narrowing to the 

 anal angle, and interrupted by projections of the brown area; three white, outwardly 

 oblique, costal fasciae, the first usually broken, and joining the white dorsal area; a 

 white apical spot covering the costal fringe, and edged below with a black crescent; 

 apical fringe brown, vaguely banded; dorsal fringe shaded with white. 9 mm. 



Moth in April and June, and again in August. Larva in a large, tentiform mine 

 on under side of leaves of oak; at first in a linear mine. (Coriscium albinatella, 

 albonotella Chambers.) 



New York to Maryland, Ohio, and Missouri. "New York" (Beutenmuller). 



III. Fore wing with one dorsal vein completely lost; R 4 and R stalked (Leuco- 

 spilapteryx Spuler). 



8. A. venustella Clemens. Head and eye -cap silvery white; palpus with two 

 blackish spots; antennae dark brownish. Fore wing dark, purplish ash gray, with 

 a white streak along inner margin from base half way to apex; a small, white, 

 antemedial, costal spot, and three somewhat convergent white streaks beyond, 

 equidistant at costa, and extending obliquely outward. Apical spot white, with 

 dark margin, and containing a black dot. Fringe mouse gray, mixed with white. 

 8 mm. (eupatoriella, Chambers). 



The moth occurs from late July to September. The larva makes several, suc- 

 cessive tentiform blotch-mines on Eupatorium. Apparently the same species occurs 

 on Ambrosia artemisice folia but I have seen only a rubbed specimen. Possibly it 

 is A. astericola. 



Cincinnati, Ohio, and District of Columbia to Pennsylvania, Kentucky, and 

 Missouri. 



4. APOPHTHISIS Braun 



Similar to Acrocercops; antennae rather shorter than fore wing, with a pecten; 

 maxillary palpi rudimentary; bristles on hind tibia rudimentary, rather like stiff 

 scales. Fore wing with R t weak, RB and M t stalked, forking over the apex; M 2 

 and M 3 absent; hind wing as in Acrocercops. 



The resting position is about as in Ornix. 



1. A. pullata Braun. Dirty white; scales fuscous- tipped; head and palpi gray, 

 antennae lightly annulate. Fore wing with darker, streaks near base and beyond 

 middle of fold; a faint, darker line in fringe. 5%-6 mm. 



The moth has been taken late in July and in May. The larva is a miner in 

 buckthorn, in July and October; the mine at first is obscure and linear, and later 

 becomes a large blotch, 5-8 mm. wide. Pupation takes place outside the mine, 

 in a flat, oval, yellow cocoon. 



Cincinnati, Ohio.
