Heterocera from Costa Rica. G23 



slightly outbent at vein 4 ; a terminal darker sliade from 

 veins 7-3. Hind wings paler, tinged with buff; a faint 

 darker line on discocellular ; a subterminal narrow darker 

 shade, followed by a fine indistinct dark line. 



Expanse 44 mm. 



Hab. Sixola. 



Closely allied to H. alinda, Druce, but the lines do not 

 converge on inner margin and the outer line is more remote 

 from discocellular. Both species show considerable variation, 

 but seem quite distinct. 



Ilylesia rubrifrons, sp. n. 



cJ . Palpi, frons, and hairs at base of antenna dark red ; 

 collar and thorax dark lilacine brown ; abdomen dark brown, 

 dorsally banded with black and overlaid with ochreous hairs. 

 Fore wings lilacine brown ; the autemedial straight, dark 

 brown, preceded by a narrow lilacine shade, and followed by 

 a broader lilacine shade ; the discal spot darker brown, 

 followed closely by the broad darker brown postmedial, 

 which is slightly oblique as in H. alinda, Dr., but is not 

 followed by a pale lilacine shade ; a subterminal lilacine 

 shade from vein 5 to outer margin above tornus; a lilacine 

 shade at apex. Hind wings lilacine ; a brown spot on 

 discocellular ; a dark postmedial line, and a broad subterminal 

 brownish shade. 



Expanse 44 mm. 



IJah. Tuis. 



The fore wings are not falcate as in H. alinda, Dr., the 

 lines are straighter, and the subterminal shade on hind wings 

 is much broader. 



Hylesia rujipes^ sp. n. 



(J . Palpi brown ; head lilacine brown ; thorax fuscous 

 brown, mottled with lilacine-brown hairs ; abdomen black 

 above, laterally, below, and anal hairs red ; thorax below 

 and legs red. Fore wings roseate lilacine, the veins 

 finely olive-brown ; an anteraedial olive-brown line, oblique 

 on costa, upbent on subcostal to near discocellular, then 

 nearly straight to inner margin, inwardly shaded below sub- 

 costal with fuscous brown, becoming- wider to submedian 

 fold ; a large dark brown shade on discocellular ; a fine 

 postmedial dark sliade suffusing at vein 4 with another line 

 remote and outcurved on costa, heavily marked below vein 4 ; 

 a terminal dark brown shade on costa ; a subterminal shade 

 parallel to outer line to vein 4, then outcurved between
