Genus Oetlobius n. gen. 



Antenna; comparatively short. Legs rather stout. 



Forewing broad and elongate, subacute but not falcate at apex, with 

 all the veins very close together. Costal area very broad at base, with a 

 recurrent vein ; costal crossveins branched and crossed ; some four or five 

 crossveins between subcosta and radius ; a basal gradate series in addition 

 to three series of discal gradate crossveins ; a little more than ten radial 

 sectors, of which the ist and the last give off a certain number of branches. 



Hindwing with only one radial sector and two series of gradate veinlets. 



Type : Oedobius infalcatas n. sp. 



This genus is closely allied to Drepanepteryx, Neuronema, Nitiguta, 

 Megalomus, etc. It can at once be distinguished from Drcpancpteryx in 

 the forewing being not falcate at apex, from Neuronema and Ninguta in the 

 radial sectors on forewing being exceedingly numerous, and from Megalo- 

 mus in having four, istead of two, gradate series of crossveins on forewing. 



Oedobius infalcattts n. sp. 



Head fulvous, somewhat paler on clypeus ; palpi fuscous ; antennas 

 fuscous black, with basal two joints yellowish. 



Prothorax fulvous, somewhat suffused with fuscous and covered with 

 long fulvous brown hairs ; vertex with two triangular dark marks in its 

 anterior portion. Meso- and metathorax dark fulvous, with an irregular 

 and interrupted median stripe above. • ■
