Imago. Head tufted above with bright saflron hairs, interrupted behind the an- 

 tennae by a transverse belt of blaclv-brown scales ; basal half of the palpi silvery white, 

 apical half saffron, mingled above with many black scale-hairs, the apical joint black; 

 antennae black above, annulate with clay-brown beneath, the basal half of the club 

 beneath clay-brown, the naked tip brighter. Thorax clothed above with brown scales 

 and hairs of various depths of color, mingled with many greenish hairs, beneath sor- 

 did white ; the legs dark clay brown. 



"Wings above uniform dark blackish brown, with a very slight tawny gloss. Fore 

 wings with a pair of small, pallid spots, a small, roundish spot at the extreme base of 

 the upper median interspace, and another larger than it in the intei'space below 

 removed a little toward the base ; these spv'ts are larger in the female than in the male, 

 and are accompanied in the latter by a row of two or three minute dashes of the same 

 color, depending from the middle of the outer half of the costal border. 



Beneath, uniform dark brown, with a purplish tinge, the lower half of the fore 

 wings with a slight tawny tint; the markings of the upper surface are repeated, 

 generally a little more distinctly. Expanse of wings, 28-31 mm. 



This butterfly belongs to the Gulf States, where it has been reported 

 from South Carolina and Georgia on the east, to Louisiana and Texas on 

 the west ; but as it has also been taken in northern Indiana, it must be 

 found over a larger extent of territory than had been supposed. 



Nothing whatever is known of its history or habits.

Imago. Head broad, the front four times as broad as high, greatly excised later- 

 ally below, uniformly and considerably tumid, surpassing somewhat the front of the 

 eyes. Vertex almost uniformly tumid with the front, and almost as considerably ris- 

 ing above the upper level of the eyes, with a transverse, coronal carina, slight and 

 short, in the middle of the summit. Eyes large, full, circular, naked. Antennae in- 

 serted in shallow depressions, greatly separated, the .space between equal to the whole 

 height of the head, slender, of about the length of the long abdomen, composed of 

 about thirty-eight joints, of which about half form the club, which is not more than 

 half as long as the stalk, very gracefully elongate fusiform or Indian-club sl)aped, 

 with a greatly attenuated, delicate, slender, tapering, pointed crook, composed of eight 

 or nine joints, nearly or quite twice as long as the breadth of the club, and about half 

 as long as it. Palpi short, the basal joints very thickly clothed, so as to appear very 



*irpt)»rs, headlong.
