Antennfe in female bipectinate; forehead with cone of scales; palpi 

 larg-e, porrect, roughly iinrrioosel.y haired, the third segment decum- 

 bent; tongue and frenulum present. 



Neuration. — Forewing-, cell more than half the length of the wing-; 

 discocellular oblique below; first median nervule at three-fourths; sec- 

 ond close to third; radials normal; 7, 8, 9 stalked from shortly before 

 end of cell; 10, 11 stalked, anastomosing strongly with 12, 10 anasto- 

 mosing again strongly with 8, 9; hindwing, costal anastomosing with 

 subcostal for more than half of cell; T from upper end of cell with 6; 

 3 from well before lower end; no radial. 



Type. — Atojwdes .si/xjidaris, new species. 



In appearance resembling the African genus JVopia, but in structure 

 of head and palpi allied to Rldnodia Guenee from Australia. The 

 abnormal anastomosis of the costal and subcostal of hindwings sepa- 

 rates it.

Forewing. — Pale fawn-color, with slightly darker transverse striae 

 and a few black atoms; costa yellowish ochreous, spotted with brown; 

 lines brown; first curved from beyond one-third of costa to one-third 

 of inner margin; outer from shortly before apex, oblique to vein 7, 

 there sharply angled and o])lique inward to two-thirds of inner mar- 

 gin, slightly waved from vein to vein; from the angle a black streak to 

 apex; cell spot dark; fringe brown with pale tips. 



Hindwing. — With base paler and hind margin darker; a dark cell 

 spot, and brown outer line, obsolete above cell. 



Under side paler, with thick olive-brown striations; inner margin 

 whitish, veins brown; outer lines brown; cell spots black. 



Head, thorax, and abdomen whitish ochreous; shoulders yellow;

Type.— Cut. No. 9108, U.S.N.M. 



Genus AVENTIOPSIS, new genus. 



Forewing. — Costa convex, strongly depressed at apex; hind margin 

 shortly but angularly excised below apex; strong!}^ in middle, straight 

 and oblique below. 



Hindwing. — Hind margin evenly curved, both angles distinct. 



Antennge of male quite simple, lamellate; palpi short, porrect; 

 tongue and frenulum present. 



Neuration. — Forewing, cell not half as long as wing; discocellular 

 v^ertical; first median nervule at one-half, second well before third; 

 radials normal; 7, 8, 9, 10 stalked; 11 anastomosing with 12; hindwing,
