of fringes fuscous ; an indistinct trace of an abbreviated sub- 

 marginal line. Underside dull oclireous, 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 millira. 



Four females from Theresopolis, Rio Janeiro, and S. Paolo. 



Hyaloplaga, gen. nov. 



Distinguished from PhlycUenia^ 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. Antenna? thick, 

 laminated and downy beneath. Female with normal wings.

LoxocREON, gen. nov. 



Fore wings elongate ; costa straight, hind margin obliquely 

 curved. Ilind 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, Wllngrn. {Salbio). 



An isolated group peculiar to the Sandwich Islands, but 

 certainly not Omiodes, as Mr. Mcyrick makes them. 



AUTOCOSMIA, gen. nov. 



Fore wing with straight costa, deflexcd 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 ; 

 antenna; (female) simple ; forehead conically projecting ; 

 hind legs with outer spurs peculiarly short; scaling smooth; 

 the veins all finely dolineatcd in white. 



Type A. concinna^ Warr. 



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.
