government of the palace of sleep, their principal duty being to inspire 

 dreams in mortals. To Morpheus was committed dreams relating to 

 men ; to Phantasos those concerning inanimate objects ; while Icelus 

 was charged ■vvitli such as relate to animate objects, through a persona- 

 tion of bird, insect, or other form. Brizo was a divinity of the island 

 of Delos, where she was worshipped as the goddess of sleep. 



The above described butterfly having heretofore been confounded 

 with jy. Brizo, the mythological name selected for it is deemed so 

 appropriate as to warrant a departure from the established custom of 

 naming the species of this genus after celebrated Koman poets. 



Nisoniades Lucilius nov. sp. Plate Y, fig. 1, ? ; 2, 6 . 



Thorax, abdomen and palpi dark brown with a red lustrous re- 

 flection, the latter tipped beneath with gi'ay. Antennae reddish 

 brown, with white annulations which are obsolete superiorly. 



Anterior wings of a lighter shade of brown than the body, and giv- 

 ing the same reflection. Discal band interrupted, fuscous, obscurely 

 defined except at its hind margin where it crosses the cell ; its course, 

 as in the other species of the genus; in the ? , and occasionally in the 

 6 , resting upon the outer one of the two cellular teeth formed by 

 this band, is a white hj'-aline spot, sometimes obsolete. The sub- 

 marginal band consists of interspaceal sagittate fuscous spots, which are 

 somewhat squarely truncated anteriorly, and have umber-colored scales 

 centrally ; its course is direct from the submedian nervure to the sub- 

 costal nervules, whence it is broadly reflected anteriorly to the costal 

 margin, embracing in this portion four interspaceal minute white hyaline 

 spots, of which the first, third and fourth are nearly in line, the second 

 and largest lying behind (in one specimen but three spots are seen) ; 

 between the median nervules there are two hyaline spots, of which the 

 inner one is sometimes obsolete in the $, , or wholly absent. Between 

 the bands the ground is nmber-brown, with a few bluish-gray scales 

 toward the submarginal baud, and a larger number between the sub- 

 costal nervules. The sagittate spots of the submarginal are bordered 

 beliind with gray (not in JY. Pe7'sius), followed by a series of 

 rounded umber spots, having a few gray scales resting on obscure 

 yellowish spots (these spots not in N. Persius) between them and the 

 brown marginal line. The cilia are umber-colored with a very few 

 basal gray scales. 



Posterior wings, of a more uniform brown than the anterior, and 

 more shaded with red. The two marginal rows of spots are usually 

 obscure, and of a yellow-brown ; the discal spots, which in Persius are 

 ordinarily visible as a transverse line across the extremity of the cell, 

 arc barely seen. The cilia are grayish-brown. 



Beneath, reddisli-brown ; the anterior wings conspicuously so at
