TJlolonche contains small species with trifoliate primaries and weak 

 characters, save as to the genitalia, which are alike in all the species. 

 The genus contains a Mamestra, a Tcenioeampa, and a species described 

 as new, but which I shall not be much surprised to recognize eventu- 

 ally as a described species of Orthosia. 



Kimella is a typical Tcenioeampid genus with reddish, luteous, or 

 dusky colors, close, smooth, glistening vestiture, and rather wide, large 

 wings, compared with the body. 



The composition of the genus is quite different from that proposed 

 by Mr. Grote, intractata being assumed as the type, since furfurata is a 

 Tcenioeampa. 



Crocigrapha is recognizable by the retracted anal angle of primaries, 

 the wings being also rather elongate. 



Orthodes contains species with rather small, broad or obtuse winged 

 primaries and generally more or less glistening vestiture. The under 

 side of primaries in the male has the cell rather densely clothed with 

 fine, long, silky hair. 



Tcenioeampa contains species varying quite considerably in wing 

 form, vestiture, and general habitus, several types of genital structure 

 being apparent. Six groups are recognizable, mainly held together by 

 their distinction from Orthodes, viz, the cell not clothed with silky hair. 



Perigrapha is distinctive. The fore wings have the apices marked, 

 acute, the thorax has an anterior divided crest, and a larger, truncate, 

 basal tuft, while in most of the species the ordinary spots are conflu- 

 ent, or at least contiguous. 



In order to bring out somewhat* more comprehensively the relation- 

 ships or differences in the genera, and the groups of Tcenioeampa, the 

 following table is added: 



Fore tibiae with a claw at tip : thorax tufted ; habitus of a Mamestra : front smooth. 



Barathra. 

 Fore tarsi with a series of long spines or claws outwardly; habitus of a T.-enio- 



campa ; front rough, bulging TriCHOCLEA. 



Fore legs entirely unarmed, save the ordinary spines of tarsi. 

 Antenme of male simple or slightly serrate ; not bristled. 



Primaries trigonate with well-marked apices and oblique outer margin. 



Moderate or rather large-sized species with ample wiugs, usually dark-gray 



colors aud powdery squammation Scotogkamma. 



Small species, shorter winged, the harpes of $ long, slender, subequal, with 



irregular long spinules at tip; clasper long, curved, slender.. Uloloncuk. 



Moderate-sized species with large primaries, rather frail bodies; close, smooth, 



glistening vestiture: harpes of $ narrow, not spinulose at tip, clasper 



long and stout Himella. 



Primaries elongate, subequal, hind angle retracted Crocighapha. 



Primaries obtuse, apices aud outer margin rounded. 



Cell of $ primaries beneath clothed with long, line, silky hair Orthodes. 



Cell of $ primaries beneath not so clothed T.eniocampa. 



Harpes of $ truncate at tip ; color white Group paWWs,
