Genus VESCOA, new. 



Legs rather slender, the tibiae without spurs; palpi very short, not 

 reaching the front; tongue obsolete; antennae short, with long bipec- 

 tinations in the male, reaching to the tip; eyes large, globose; body 

 parts moderate, the abdomen very short. Wings rounded, trigonate; 

 fore wing with vein Ic present, straight, continuous ; 2 to 5 well 

 separated; 3 to 5 evenly spaced, the cross-vein of the cell angularly 

 reentrant, the discal vein touching the point and not forked; 6 from 

 much below the angle of the cell; 7 and 8 long-stalked; 9 near the 

 base of the stalk; 10 absent; 11 from the outer fourth of the cell, 

 anastomosing with 12, the cell long; hind wing with veins 3 to 5 evenly 

 spaced; cell with a reentrant cross-vein as on fore wing; 6 from much 

 below angle of cell; 8 anastomosing with the cell to very near the 

 apex; frenulum of the male distinct, with a narrow costal loop on fore 

 wing. 



Vescoa ma, new species. 



Head and thorax white, abdomen gray. Fore wing dark gray, all 

 the veins, the fringe, and inner margin narrowly white. Hind wing 

 white with gray streaks between the veins outwardly. Expanse 

 15 mm. 



One male, Iquitos, Peru, July 17, 1906 (B. A. Griggs). 



Type: No. 13127, U. S. National Museum. 



This peculiar dwarf species is remarkably small for a 

 megalopygid, looking rather like acochlidiid. The venation, 

 however, refers it clearly to the former family. The only 

 other small and degenerate genus in the family is Cyclara 

 Schaus, which is not so small as this and apparently derived 

 from Megalopyge, whereas Vescoa is allied to Norape and the 

 other white forms.
