432 Mr. W. Warren on new 
of fringes fuscous ; an indistinct trace of an abbreviated sub- 
marginal line. Underside dull ochreous, with darker suffu- 
sion; external line of both wings distinct; veins of fore 
wings dark. Head, thorax, and abdomen all sandy ochreous. 
Expanse of wings 24 millim. 
Four females from Theresopolis, Rio Janeiro, and §. Paolo. 
HYALOPLAGA, gen. noy. 
Distinguished from Phlycteenta, which in shape and appear- 
ance it much resembles, by several structural differences. 
Labial palpi not rostriform, but bluntly triangular, slightly 
porrected upwards. In the male the hind wings have a very 
prominent shoulder near the base. Fore wings with the sub- 
median nervure somewhat distorted, curved downwards 
towards the interno-median fold, and with a small tuft of 
hairs on the upper surface near the base. Antenne thick, 
laminated and downy beneath. Female with normal wings. 
Type H. pulchralis (Hydrocampa), Moore, P. Z. 8. 1867, 
p- 90. 
LOXOCREON, gen. nov. 
Fore wings elongate ; costa straight, hind margin obliquely 
curved. Hind wings rounded, slightly indented beneath 
apex. Labial palpi broad, triangular, porrect; maxillary 
palpi short, erect ; tongue and ocelli present; eyes large ; 
patagia of male prolonged, as in Omiodes, but not to nearly 
the same extent; abdomen stoutish, of the male prolonged. 
Wings smoothly and thickly scaled, with oblique markings. 
Type L. continuatalis, Wilngrn. (Salbia). 
An isolated group peculiar to the Sandwich Islands, but 
certainly not Omiodes, as Mr. Meyrick makes them. 
AUTOCOSMIA, gen. nov. 
Fore wing with straight costa, deflexed only just before 
the apex, which is produced, but not acutely ; hind margin 
straight, oblique. Labial palpi porrect, rather long ; maxil- 
lary upright, small; tongue developed; ocelli present ; 
antenne (female) simple; forehead conically projecting ; 
hind legs with outer spurs peculiarly short; scaling smooth ; 
the veins all finely delineated in white. 
Type A. concinna, Warr. as 
The only species, from N.W. America, is separated from 
Cosmocreon by its conical, not rounded forehead, the smooth- 
ness of the scaling, and the peculiar neatness of the markings.
