 on the middle of the wing. Discal dots on both wings brown. Abdomen 

 green, whitish on the edges and sides of the segments. Costa of fore wings 

 whitish, tinged immediately on the edge with brown; beneath, deep brick-

£ and 9. — Head square in front, the sides converging a little ante- 

 riorly. Antenna? moderately pectinated. Palpi in the male large and 

 bushy, extending well beyond the bead, the third joint less than half as 

 long as the second joint is wide; in the female, the third joint is somewhat 

 longer, and the palpi project farther beyond the head than in the male. Fore 

 wings very slightly subfalcate, the costa full near the subacute apex ; the 

 outer edge is rather more oblique than usual, and usually distinctly bent in 

 the middle. The hind wings are elongated toward the inner edge, the anal 

 angle projecting farther than usual beyond the tip of tin; abdomen ; tin; 

 outer angle is slightly bent. Venation much as in Aplodcs, the posterior 

 discal venule being curved as in that genus; the costal region becomes 

 very narrow toward the apex, while the space usually represented by the 



subcostal cell is considerably wider than usual; the origins id' the first and
