Vein 5 of secondaries absent; areole present, vein 5 arising close to 

 upper angle of cell, vein 6 from the middle of the areole, 7 from end 

 of areole, 8 and 9 stalked, 10 from before end of areole, which is long 

 and narrow; vein 8 of hind wings diverging from 7 at middle of cell, 

 veins 3 and 4 separate, 6 and 7 shortly stalked. Antennae pectinated on 

 the basal portion. Wings broad, trigonate, normal, the inner margin 

 without scale-tuft. 



Center of thorax reddish brown, patagia grayish clay-color; abdomen 

 brown above, the segmental rings lighter, beneath whitish clay-color. 

 Fore wing whitish clay-color; a large chocolate-brown patch from base 

 on costa to the outer line, reaching vein i to middle of wing, then 

 obliquely waved to vein 3, on which and on vein 5 is a rounded pro- 

 jection; the inner line cuts this patch as a zigzag dash on the ground-

 vein 2; a large rounded, cloudy-black discal spot; in the broad pale

 inner edge, following the outer margin and diminishing in width 

 toward both apex and tornus. Hind wing brown, paler at the base,

Nagidusa cinescens Schaus. 



Nagidusa cinescens Schaus, Trans. Ent. Soc. Lond., p. 322, 1901. 



Macrurocampa marthesia, var. miranda Dyar, Sci. Bui., Brookl. Inst., 

 i: 7, 185, 1905. 



The above synonymy will obtain. Nagidusa Walker differs 

 from Macrurocampa Dyar in having" veins 3 and 4 of second- 

 aries apart ; otherwise the genera are closely allied. N. cines- 

 cens Schaus must be added to the North American list.

 tennae, collar dark brown, patagia gray, variegated with brown ; abdomen 

 gray dorsally, the anal tuft somewhat ocherous. Fore wing gray-brown, 

 tinged with reddish ; base lighter, the subbasal line black, geminate ; 

 inner line faintly indicated by a fine zigzag black line; a small black 

 discal point; outer line indicated, waved, brown-black, closely followed 

 by a row of rounded black spots ; a subterminal row of black spots
