Second joint of palpi closely appressed, densely clothed with scales in which the small third joint is almost concealed. An- tennae about one-half as long as the primaries, club more or less sharply curved at the middle. Head not quite as wide as thorax. Primaries elong- ate, rather narrow; outer and inner margins about equal in length, outer slightly more oblique but otherwise similar to Goniurus. Costal fold pres- ent. Cell three-quarters as long as wing; vein 5 slightly nearer to 4 than to 6. Recurrent vein nearer to vein 3. Vein 1 strongly sinuate. Seeon- Fig. 5. a.
