ATHRINACIA. 105 
from a narrow base, costa straight, apex depressed, obtuse, termen oblique, tornus rounded: neuration 
11 veins; 7-8 coincident, to costa; 2-6 separate, 2 remote from 3; 1 not basally furcate (1° obsolete). 
Hindwings 13, apex obtuse, termen sinuate; cilia -3: neuwration 7 veins; 3-4 coincident in ¢ and 9; 
5 subobsolete, cubital; 6-7 separate, but approximate. Abdomen smooth. Legs: hind tibiae slightly 
hairy above. . 
This genus differs from Dichomeris Hb. in the separation of FW: 2-8, in which it 
agrees with Nothris Hb., but is separable by the coincidence of HW: 3-4; this 
character is apparently new among American Gelechiadae, |

1. Athrinacia trifasciata, sp. n. 
Antennae rather stout, shorter than the forewings; lilac-grey. Palpi slender, smooth, slightly recurved, the 
terminal joint about as long as the median, acute ; whitish ochreous. feud rather rough above; whitish 
ochreous. horas mottled, or streaked alternately, with lilac-grey and straw-yellow. orewings bright 
straw-yellow, with three lilac-grey transverse fasciae, each narrowly margined by a darker line ; the first, 
‘leaving the costa at one-third from the base, is obliquely attenuated downward reverting to the dorsum 
from the fold; the second, rather wider at about the middle, is outwardly sinuate on the cell ; the third, 
at the commencement of the costal cilia, moderately straight, but broken and diffused on its outer edge 
toward the termen, which is marked by a narrow toothed line of pale tawny brown running around 
the apex ; along the base of the dorsum is a narrow, elongate, lilac-grey streak ; between the first and 
second fasciae is a tawny brown dorsal spot, another lying beyond the end of the cell between the second 
and third fasciae; cilia bright pale ochreous. Exp. al.13 mm. Hindwings pale grey ; cilia shining, 
inclining to ochreous. Abdomen brownish grey. Legs shining, yellowish white ; the hind tarsal joints 
very faintly spotted, the anterior pairs of legs streaked and spotted with dark brown.

9. Athrinacia xanthographa, sp. n. (Tab. III. fig. 27.) 
Antennae simple; yellowish brown, yellowish at the base beneath. Palpi yellow, slender throughout, the 
median joint shaded with brownish externally. Head brownish grey above, yellow at the sides, Thorax 
brownish grey. Forewings lilac-grey, with pale yellow bands and spots enclosing patches of yellowish 
brown, these are distributed as follows: a yellow patch at the base is produced along the upper edge of 
the cell, emitting an ocelloid patch with brown centre which reaches to the dorsum at one-fourth; a
