or witli a brownish tiugo not unlike the color of a cherry stone; labium and autciuno paler, the latter with two 
black rings; jaws black; eyes blackish. Body black, the stripes pale yellow, the lateral ones in some examples 
becoming white and in a few canary-yellow; narrower than the intervening spaces, continuous from cervical shield 
and the anterior edge of joint 2, except the siibventral ; somewhat interrupted and irregular on joints 12 and 13, 
and barely reaching the anal plate, except the third lateral. Cervdcal shield, anal plate, and abdominal feet, oxcejit 
an outward blackish band on the latter, concolorons with the head. Bases of all the legs (except the anal) and 
corresponding spots on the legless segments darkt'V red. Thoracic 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. I’npation occurs in a subterraneous cell, and the winter is passed in this state. 
Pupa. — Similar in shape and color to those of the other species of Vatuna and not to ho distinguished from them. 
The two cremasters are short, each with three spines, of which the middle one is usually shortest.

dibf/t. — Exterior margin of wings rather distinctly scalloped, almost as much so as in I>. major. 
Thoracic patch ocliraceons (E., Y, 7), scarcely darker posteriorly, paler than the thorax. Thorax 
and primaries “hazel” (E., IV, 12), bnt darker than the plate, with scarcely any costal shade. 
Lines obsolete, tlie first and fifth just discernible, a shade darker than the wing. Fringe 
concolorons. Disoal dot large, distinct, blackish. At base and terminally, below the obsolete 
apical streak, a yellowisli shade prevails, concolorons with thediscal dots. Secondaries, abdomen, 
and underside almost exactly as in 1). flori<lana.,h\\t the foi’e wings are in the present species 
brighter in tint, and the secondaries lack the peculiar gloss floridana ami palmiL 
Expanse of wings: 9 , 51 mm. (no 3 ). 
A distinct species, which, in the absence of all knowledge of the larva, finds, we think, its 
nearest allies in Jloridana and major. The type is in the collection of Mr. diaries Palm. 
GeograpMcal distribution, — Florida (Graef); Kissimmee, Fla., May (Palm); Florida (Palm, 
French).
