'Tis thine to wander wiiere the rose 



Perfumes the cooling gale. 

 To Ijask upon the sunny l)ed, 



The damask lluwcr to kiss, 

 To range along the bending shade, 



Is all thy little bliss. 

 Then flutter still thy silken wings, 



In ricli eniltroidery dressed, 

 And sport upon the gale that flings 



Sweet odors from his vest. 



Taylor.— To a Butterfly. 



Imago. Butterflies of medium size. Head of moderate size. Front slightly 

 tumid, scarcely protuberant beneath. Antennae inserted each in distinct, entirely dis- 

 connected pits, and consisting of from forty to forty-five joints, slender, straight, 

 scaled, a little longer than the abdomen, the club rather ill-defined by the gradual 

 incrassation,but elongated. Palpi exceedingly long and moderately stout at base, 

 heavily beset with long scales. 



Thorax moderately stout, not much compressed, upper surface considerably vaulted, 

 a little protuberant in the middle ; anterior sides of mesoscutellum gently hollowed, at 

 the apex projecting but little between the halves of the mesoscutum and yet, because 

 of the elevation of the fonuer, forming with each other not much more than a right 

 angle; posterior border well rounded, largely protuberant in the middle; metascu- 

 tellum very inconspicuous indeed, formed of a triangular piece facing posteriorly, 

 the apex not greatly elevated, and its tip only appearing above; metascuta pretty well 

 developed, protecting the rear of the mesoscutellum and bent strongly in the middle 

 to eflect it, the upper border strongly arched. 



Fore wings produced to a considerable degree above the median region and strongly 

 angulated, tlie middle of the outer border very strongly and abruptly excised. Costal 

 nervure terminating at the middle of the costal border; two superior branches of the 

 subcostal nervure emitted before the tip of the cell, the other two beyond,— the infe- 

 riors arising much as in the Nymphalinae ; discoidal cell nearly half the length of the 

 wing, closed by rather a slender vein ; first branch of the median nervure arising 

 somewhat beyond the middle of the cell, the last curving toward the subcostal to 

 which it is connected by a slender vein; internal nervure very slender, running into 

 the submedian at a short distance from the base. 



Hind wings subquadrate, the outer border for the greater part nearly straight, but 

 crenulate; the costal margin sometimes lobed apically. Costal nervure terminating 

 nearly as far from the base as the lower outer angle of the fore wings ; subcostal 

 nervure apparently taking its rise as a dependent of the costal, its lower branch curv- 

 ing at base toward the median ; discoidal cell closed by a very feeble vein uniting the 

 laJt branch just beyond its curve to the subcostal just beyond the origin of the second 

 branch, directed outward in passing from the subcostal toward the median; the 

 branches of this vein arise farther from tlie base of the wing than those of the sub- 

 costal, the first branch some distance beyond the middle, the last branch curving 

 pretty strongly near the base toward the subcostal; submedian nervure terminating at 

 or before the anal angle ; internal nervure terminating before the middle of the inner 

 border, the latter aflbrding a gutter on its basal half for the reception of the abdomen
