or with a brownish tiiigo not luililic the color of a clierry stone; labium and antenna' paler, tbo latter with two 

 blaok rinys; jaws black; eyes blackisb. Body black, tbe stripes pali^ yellow, the lateral ones in souio examples 

 becominij wbite and in a few canary-yellow; narrower than tbe intervening spaces, continuons from cervical sbield 

 and tbe anterior edge of joint 2, except tbe snbventral; somewhat interrni)ted and irregular on joints 12 and 13, 

 and barely reaching the anal plate, except tbe third lateral. Cervical shield, anal plate, and abdominal feet, except 

 .an outward bl.ackish baud ou the latter, concolorous with the head. Bases of all the legs (except the anal) and 

 corresponding spots on the legless segments darker red. Thor.acic and anal feet black. Hair thin, about 5 mm. long, 

 with some short, more numerous, fine black hairs, seen with a lens. At maturity the head is more of a brownish red. 

 Length, about 50 mm. Pupation occurs in a subterraneous cell, and the winter is passed iu this state. 



Pupa. — Similar in sha])e and color to those of the other species of Datana and not to be distinguished from them. 

 The two cremasters are short, each with three spines, of which the middle one is nsually shortest.

Moth. — Exterior margin of wings rather distinctly scallojied. almost as ninch .so as in J>. major. 

 Thoracic patch ochraceous (It., V. 7), scarcely darker posteriorly, ]ialer than the thorax. Thorax 

 and primaries "hazel" (I!., IV, 12), but darker than the plate, with scarcely any costal shade. 

 Lines obsolete, the lirst and tifth Just discernible, a shade darker than the wing-. Fringe 

 concolorous. Discal dot large, distinct, blackish. At base and terminally, below the ob.solete 

 apical streak, a yellowish shade prevails, concolorous with the discal dots. Secondaries, abdomen, 

 and underside almost exactly as in I>. foridmiu, liut tlie fore wings are iu the present species 

 brighter in tint, and the secondaries lack the peculiar gloss oi ^ttoridrnxi and pnlniii. 



P^xpanse of wings: 5 , .51 mm. (no S ). 



A distinct species, which, in the absence of all knowledge of the larva, finds, we tliink. its 

 nearest allies in foiidana and majur. The type is in the collection of Mr. Charles Palm. 



Geographicul distribution. — Florida (Graef); Kissinjinee, Fla., May (Palm); Florida (Palm, 

 French).
