cloud; these are followed by a more distinct one near the outer margin : 

 near the centre of the wing is an oval white or whitish sjjot, in which 

 are two small black dots placed close together : on the margin is a 

 series of black dots, and the cilia, which are ash-coloiu'ed, have a black 

 dash opposite the termination of each nervure. Posterior wings fus- 

 cous ash, cilia the same. 



This species is rather variable. In some individuals the white spot 

 is destitute of the black dots, in others the dots are united and the 

 white around them is less distinct. It is just possible that there may 

 be two species among the specimens I have placed together, but there 

 are so many intermediate specimens between the extreme variations, 

 that I am inclined to believe they constitute but one species. 



Abbot's drawing coincides exactly with the Georgian specimen in 

 having the white spot very distinct, and the two black dots clear and 

 separate, I have one northern specimen in which the white is im- 

 maculate, and another in which the united black dots cover the whole 

 of the space which in general is white. The larva (fig. 6) is of a dull 

 green, with a darker dorsal line. In the south its food is Pinckneya 

 pubens, I do not know on what it feeds in the north. 



Genus. — Sciiizura, Douhleclay. 



Maxilla) about as long as the thorax : labial palpi moderate, por- 

 rect, triarticulate, densely clothed; first joint nearly cylindrical, slight- 

 ly incrassated at the apex, curved; second joint one half longer than 

 the first, cylindrical, very slightly curved, obliquely truncated at the 

 apex ; third joint less than one third the length of the second, much 

 slenderer, oval, inserted below the ajsex of the preceding one : anten- 

 n£e of the male bipectinate for about half their length, the pectinations 

 fringed with very fine seta) ; antenna) of the female setaceous : thorax 

 densely clothed, not crested on the disk, anterior margin with two 

 small almost conical tufts of hair-like scales directed forwards and in- 

 wards, so as to meet above the head, to which at first sight they ap- 

 pear to belong : anterior wings trigonate, rather elongate, entire : an- 

 terior tibia3 furnished, in both sexes, with an elongate corneous jDlate; 

 posterior quadrispinose : abdomen not very stout, elongate, of the 

 male with a bifid anal tuft, of the female not tufted. 



This genus is certainly near to Notodonta, but may at once be 

 known from that genus by its antenna), and the presence of the poste- 

 rior stigma, which in the females is very distinct. I captured three 

 species in the United States, two in East Florida, one, by far the most 

 beautiful, at Trenton Fulls.
