form, outwardly deeply indented and black marked. In common with 

 the two following species this has a pale apical spot, and a well marked 

 claviform. 



Chalcedonia is narrower-winged with similar maculation, save that 

 the reniform is smaller, and narrow ; the costal region is also pale as a 

 rule. The secondaries are white, hyalme, in both sexes. 



Exesa is larger and more robust, more evenly colored ; but else 

 very like chalcedonia in maculation. The secondaries are fuscous 

 brown. 



The other species lack the apical pale spot and the claviform, the 

 type of maculation being otherwise the same. 



Fuscimacula is a very pretty, evenly colored species, grayish fuscous, 

 the lines broad, pale and well defined, and the ordinary spots dusky. 



Grata, or rasilis as it is generally named, is red-brown, the median 

 lines narrow and white, renifurm strongly constricted, with a dusky spot 

 above and below. 



Paginata is dull, smoky fuscous, the maculation obscure and only 

 the median lines well marked and dark — decidedly different from all 

 allied forms. 



Versicolor Grt. , is known to me in nature, and I have given the de- 

 scription a place next to chalcedonia which it seems most nearly allied 

 to, not having been able to obtain a specimen for study at the time of 

 writing. 



In synoptic form the species will appear as follows : 



Apical spot and claviform present. 



Reniform large, oval, indenttd outwardly and black marked ; primaries proportion- 

 ately shorter and broader festivoides 



Narrower winged, reniform smaller and narrow. 



Size smaller, costa usually discolorous paler, secondaries hyaline, whitish in both 



sexes chalcedonia 



Size larger, color more even, secondaries fuscous brown exesa 



Primaries without claviform or pale apical spot. 



Ground color yellowish-gray or fuscous, ordinary spots dusky, median lines broad, 



paler, well defined fuscimacula 



Ground color red-brown, median lines narrow, pale ; reniform strongly constricted, 



with a dusky spot above and below grata 



Dull smoky fuscous, maculation obscure ; median lines dark broad paginata 



The species all agree in the general type of male genitalia. In all 

 the harpes (which I have heretofore called the ''side pieces" — for my 

 term supra-anal plate I shall hereafter use the term uncus,) are elongate, 

 narrow, with a rounded tip, somewhat curved, and broadening suddenly 

 toward base, where the clasper is inserted. This latter is very various 

 in form and will be described with the species.
