fuscous. Tc'iniiiiiil sjnice very iire^jfuliir, fuscous, projecting n loiij;' 

 tooth inwardly oi)posite cell, and a second on submedian intersi)ace. 

 The space is con)i)letely cut on veins 3 and 4 by iiulentations of the 

 s. t. line, which is marked l>y black cuneilorni spots. Ordinary spots 

 small, indelinite, obscured or entirely absorbed in the strigate macu- 

 hition; orbicular small, V-shai)ed, connected by the ochery shading 

 with the small, upright whitish rin;;ed renilbiin. Secondaries white, 

 with a narrow dusky outer margin. Beneath whitish; powdery. 



Expands 32-3.3 """ ; 1.30-1.40 inches.

I have seen the type of this species from Dr. Bailey's collection and 

 the type ot cloanthoUles from Mr. GraeCs collection. The former looks 

 like a washed out specimen of the latter, but the markings are iih'Uti- 

 cal. 1 have seen other specimens, princii)ally of the doanlhoidcH 

 form, and believe the type of albalis to be a faded specimen, which can 

 not well be matched among fresh material. 



Genus FELTIA Wlk. 



The distinctive characters of the species grouped under the present 

 term are spinose and quite heavily armed fore tibi;e; protuberant, 

 rough front, pectinated or serrate antenna^, usually wide wings with 

 dark colors and a tentlency to a radiate type of maculation. With 

 this genus begins the series of forms in which the S genitalia are after 

 a single tyi)e, so that the type can be used in the subdivisions of the 

 series of species. In the species grouped here, the harpes are as a 

 whole oblong, the sides not straight, but tolerably i)arallol, thetij) ob- 

 rujuely rounded, the margin inwardly set with spinules. The clas[)er 

 consists of a single, simple, curved hook, variable in length, but very 

 much alike in the species, so that it does not afford very good char- 

 acters. There is one other — the following — genus which agrees in all 

 these structural features, but differs essentially in habitus and wing 

 form and in which the clyi)eal projection becomes cylindric, and more 

 developed in type. 



I have recognized two groups or series of species, the one, of which 

 subgothica is typical, characterized by the open, V shajjcd orbicular 

 and paler costa, the other, of which vcncrabilis may be considered the 

 tyi)e in which the orbicular is complete or at least not open to the costa, 

 and in which the radiate type of n)aculation is sometimes strongly 

 developed. 



There are two aberrant species, annc.va and malcfitla, with narrow 

 wings and more normal type of maculation, that should perhai)s have 

 also ranked as a group and must at least rank as a subdivision of the uen- 

 crahilis series. The s{)ecies of both groups are confused, and perhaps 

 in the allies of vancoHVcrcnfiis the solution here, is not the true one. The 

 difiiculty of applying the proper insects to existing names ia a cousid-
