subcostally and bctweea veins 2-4; basal space marked with black;

 by white points on the veins, angled at subcostal and moderately 

 drawn in; subtermmal line vague, irregular; orbicular fragmentary,

r^pe.— Female, No. 19262, U.S.N.M.; Zacualpan, Mexico, May,

Genus NEPHELISTIS Hampson. 



NEPHELISTIS OOMAE, new species. 



Fore wing dark brown, nearly black; median space black-filled 

 between the lines and stigmata, but not contrasted on account of 

 the general dark color; lines double, slightly violaceous fiUed, oblique, 

 approximated on inner margin, the outer curved over reniform and 

 slightly dentate; orbicluar and reniform large, similar, slightly 

 violaceous, the reniform with a white speck outwardly; subterminal 

 line faint, irregular. Hind wing fuscous, paler at base; a discal 

 spot and curved mesial line. Expanse, 26 mm. 



Type. — Male, No. 18857, U.S.N.M.; Zacualpan, Mexico, August, 

 1910 (R. Muller). 



Subfamily Acronyctinae. 



Genus HOMOLAGOA Barnes and McDunnough. 



HOMOLAGOA TRITOGRAMMA. new species. 



White, palpi black; abdomen broadly banded with black dorsally. 

 Fore wing with a black dot near base of costa, inner row of three, 

 mesial row of three above median vein, followed by a line from vein 

 2 to mner margin. Hmd wing lightly dusted with black outwardly 

 and a faint mesial line. Below, fore wmg heavily dusted with 

 black except along inner margin. Hind wing white with large black 

 discal spot, mark on outer third of costa and slight dusting out- 

 wardly. Expanse, 24 mm. 



Type.— Male, No. 18858, U.S.N.M.; Sierra de Guerrero, Mexico, 

 July, 1913 (R. MiiUer). 



Nearly allied to H. groteUiformis Barnes and McDunnough.^ 

 Barnes and McDunnough place the genus in the Erastriinae, but 

 I have preferred the Acronyctinae on general habitus, especially 

 as some of the species of Antaplaga show vein 5 of hind wing about 

 as well developed as in Ilomolagoa and in much the same position.
