strongly splnose. Color of the anterior wings variable in the female, — 

 different shades of clay or brick red. All of the eight males examined 

 were much worn, and almost colorless. There is a narrow black 

 shade along the costa in the median space. Beneath this shade, 

 above the reniform spot, and to the inception of the exterior line, 

 there is a more or less distinct whitish cinereous shade. A black spot 

 on the median nervure at its base. Orbicular spot reduced to a simple 

 black spot, occasionally white-centred. The median shade is pres- 

 ent as a diffused blackish band, forming a regular outward curve, its 

 two extremities being at a nearly equal distance from the base. 

 Reniform spot narrow and subquadrangular, yellow and very distinct, 

 with an indistinct black central shade, which culminates in a black 

 spot at the junction of the median nervure and fourth median ner- 

 vule. Beyond the reniform, the median space is black to the exterior 

 line, which consists of clear white dots on the nervules, most evident 

 on the lower subcostal and upper median branches. Subterminal 

 line a blackish undefined shade. A series of terminal dots. Poste- 

 rior wings in the female fuscous, in the male lighter; in both sexes 

 there is an interrupted black line at the base of the fringe. Beneath, 

 the wings are without bands or spots, the anterior grayish fuscous, 

 tinged with reddish along the costal margin; the posterior whitish. 



Hab. Tuckernuck Island, near Nantucket. (Mr. Edward Burgess.) 



Quickly identified by the pectinated antennas, the uniform red- 

 dish hue only interrupted by the conspicuous yellow reniform spot, 

 and the cinerous and blackish markings above and beyond it. 



This species had not, until now, been rediscovered since its de- 

 scription by Guenee from a single male specimen ; the reception after 

 the above description was written of males in perfect condition, has 

 enabled me to make the identification. 



Eurois astricta nov. sp. 



Expanse 60 mm. Length of body 25 mm. 



A very large, stout form. Eyes naked, unlashed. The head some- 

 what sunken. The antennas of the female showing fine, short bristles. 

 The collar and thorax are smoothly and closely haired, the former 

 rounded, and not separated from, or elevated above, the latter. The 

 abdomen very stout, cylindrical and heavy, slightly exceeding the 

 posterior wings; untufted. All the tibiae spinose. The anterior 

 wings are gray, strongly suffused with brown, the subterminal and 

 terminal spaces darker. The half-line present. The median lines 

 are geminate, with broad pale included bands. The interior nearly
