inner margin, especially near the costal and inner borders. Secondaries 

 grayish-brown, becoming paler basally, with two faint transverse, median 

 dusky bands. Under surfaces gray-brown, yellowish toward base, the dark 

 bands of upper surfaces, except the basal one on primaries, faintly indi- 

 cated. Body yellowish, the head and prothorax bushy and deep brown- 

 black, the color not abruptly separated across the shoulders, but tapering 

 on to the mesothorax; the prcmotum, palpi above, front femora and tibia- 

 above, and the other tibia; toward their tips, dusky. The abdomen also 

 sometimes dusky above toward tip. Expanse o.S-1.05 inch.

and the second or median one may be a little within 



or without the middle of the wing, regular or irregu- 



Xaxthopteka riding- lar on its posterior margin, while the yellow space 



sii. between it and the broad posterior band may be 



obsolete (2 specimens) or subobsolete (1 specimen). 



Larval habits unknown. 



The specimens were collected in Alabama by Mr. J. S. Ridings, 

 to whom I take pleasure in dedicating the species. In colors it 

 closely approaches scmicrocea, of which it has been considered a 

 variety. It is however a brighter, more graceful species, the pri- 

 maries being somewhat narrower, with the posterior border more 

 oblique : and while scmicrocca varies greatly, in none of the 

 specimens that I have examined is there the slightest approach to 

 the basal dark band in the primaries, or to several of the other 

 characters indicated. 



Genus Cerura Shrank. 



Cerura multiscripta, n. sp. (Fig. 13 $.) — Color white with brown- 

 black and black markings. Primaries white, slightly silvery, crossed with 

 8 irregularly undulate and angulate, narrow, black lines, as follows: 1, 

 basal, obsolete on costal and inner borders, and preceded by a black spot 

 close to thorax ; 2 reaching to both borders, but broken ; 3, 4 and 5 proxi- 

 mate, and irregularly undulating almost straight across the basal fourth 

 of wing, 3 and 4 thickened and confluent toward costa and generally form- 

 ing a circular spot between subcc-tal and median veins: 6, 7 and S ob- 

 liquing more toward apex, lunulate and more widely separated between 

 veins 2-3-4, more approximate and retreating toward base between veins 

 1-2 and 4-6, and generally so close along vein 2 as to coalesce : broader, 

 more intense, irregular marks occupy the spaces toward apex and anal an- 

 gle, left by the retreating of line 8, thus leaving a regularly denned terminal 

 space. Veins more or less dusted with black, and conspicuously marked 

 in terminal space. A distinct row of terminal spots between the veins,
