Type 2 (598U Wlsm. Det. 1908) US. Nat. Mus. 
Hab. Mexico: veRA cruz: Cordova, LV. 1908 (F. Hnab). Unique. 
A very distinct dark species, somewhat resembling Strodisia in wing-form. 
11. Dichomeris arotrosema, sp. n. 
Antennae slightly serrate; black above, pale cinereous beneath, annulate with pale cinereous on and near 
the basal joint. Palpi with the median joint clothed with a large fan-like expanding tuft which recedes 
equally above and below from its apex, greyish fuscous, profusely sprinkled with whitish cinereous ; 
terminal joint slender, subochreous, tipped and shaded beneath with fuscous. Head greyish fuscous, 
profusely sprinkled with greyish cinereous. Yhorax dark chocolate-brown, the tegulae tawny. Forewings 
dark chocolate-brown along the dorsum to two-fifths, this colour being diffused upward and outward 
obliquely, nearly reaching the costa beyond the middle, blending on its outer side into dark tawny fuscous, 
which embraces the whole outer haif of the wing and cilia, but is slightly sprinkled with pale cinereous 
scales leaving a large pale tawny patch at the base of the costa, attenuate outward to a little beyond 
the middle, a small pale tawny dorsal spot lying before the tornus. wp. al. 17-22 mm. Hindwings'1, 
trapezoidal; dark brown; cilia brownish grey, somewhat darkened around the apex. Abdomen dark

12. Dichomeris nessica, sp. n. | 
Antennae pale cinereous, dotted with blackish above. Pulpit: median joint with a wide, somewhat quadrangular

Head fuscous, paler at the sides. 1’horaw tuscous in the middle; tegulae brown, mixed with cinereous. 
Forewings somewhat narrow, costa flattened in the middle, apex depressed, falcate, termen sinuate ; 
commencing at the base is a large greyish cinereous patch, which, after following the fold nearly to its 
middle, is attenuate upward and outward to the commencement of the costal cilia; the remainder of tie 
wing is of varying shades of dark chestnut-brown, containing a small black spot on the fold, and a larger 
cireular spot of the same colour at the end of the cell; a faint shade, rising from before the tornus, runs 
nearly parallel with the termen and vanishes half-way between the discal spot and the apex; cilia 
brownish ochreous, with a brown line along their base, the costal cilia inclining to ochreous ; underside
