type; the apical spot is larger, lilac gray and not white, and in neither 
wing is there any trace of white cell spot; these were probably lilac 
gray and worn off. 
Subfamily HNNOMIN AS. 
NEREIS, new genus. 
Fore wing—Triangular; costa straight till shortly before apex, 
which is blunt; hind margin straight; anal angle well expressed. 
Hind wing—With both angles rounded; hind margin slightly 
curved; inner margin long. 
Antenne of male ciliated; palpi upcurved in front of face; tongue 
and frenulum present, the latter very fine, white; hind tibiee thick- 
ened, with four short spurs and apparently without hair tuft. 
Neuration.—Fore wing, cell half of wing; discocellular vertically 
concave; postmedian nervule from just beyond middle, second close 
before third; radials normal; 7, 8, and 9 stalked from before end of 
cell; 10 and 11 coincident, anastomosing at a point with 12, 10, again 
anastomosing at a point with 8 and 9; hind wing, costal and subcostal 
quite shortly approximated near base, 7 and 3 from before angles 
of cell. 
Type.—Nereis opalina, new species. 
Syllewis Guenée, Gonogala Butler, and Gonorthus Butler are its 
nearest alles; from them all it is distinguished by the entire hind 
margins of both wings. 
NEREIS OPALINA, new species. 
Fore wing.—Subtransparent, very pale greenish white; the costa 
cream color; two broadish white lines; the first well curved, at one- 
third, the outer from two-thirds of inner margin, oblique, above vein 
4 bent outwards toward hind margin, shortly retracted to costa before 
apex, where it ends in a short streak of crimson scales; beyond this 
is another, rather larger, spot of red and black scales which is appa- 
rently the commencement of a submarginal line; cell spot white, like 
the lines; fringe pale yellow. 
Hind wing.—Without basal line; the outer straight from just be- 
fore apex to just above anal angle. Under side whiter; costa of fore 
wing yellowish; marginal third of both wings beyond outer line 
denser white. Thorax and abdomen white; palpi white, externally 
black-brown; face and vertex white varied with deep red; fore legs 
in front and antenne ferruginous. 
Haupanse of wings.—34 mm. 
Locality.—One male from Santiago, Cuba, January, 1905. The 
species might easily be mistaken for a Dechorda. 
Type.—Cat. No. 11409, U.S.N.M.
