These species are again divided according to wing shape; most of 

 them having the costa straight or somewhat convex, the apices not 

 produced. 



Monochromatea is distinguished by the even, parallel transverse lines, 

 the ordinary spots wanting. The type is a 5 , but in such condition 

 that it is impossible to get at the genitalia Mithout great risk of break- 

 age. 



Manifesta is similar, but the transverse lines are not parallel, their 

 course normal J the ordinary spots present but as dark indeflned ma 

 cula. The $ genitalia almost precisely like the typical form in the 

 muramula group. 



FerriKjinoides is somewhat paler in color, the veins darker marked, 

 the ordinary maculation neatly defined; the ordinary spots concolor- 

 ous. The genitalia are distinctive. The harpes are semi-corneous; the 

 inferior margin thickened, tapering toward the tip, and terminating in 

 a somewhat blunt point ; the clasper arises from this lower rim, is long, 

 corneous, and curved. 



In the other species of the section the costa of primaries is depressed, 

 somewhat more so just before apex, causing the latter to appear some- 

 what drawn out. 



Salicarmn, of which claviformis and orilUana are synonyms is distin- 

 guished by the very distinct velvety dark brown claviform. The S 

 harpes are rather narrow, corneous, the tip abrupt and irregular. The 

 clasper is a simple short corneous hook similar to that in manifesta. 



OlcaTcensis differs from the preceding by the lack of claviform and by 

 the discolorous gray terminal space. The $ genitalia are unknown to 

 me. 



Carnea has serrate S antenna, thus differing at once from all the 

 preceding species. The cell is always dark*, relieving the usually con- 

 colorous ordinal^ spots ; the t. a. line is oblique, even. Cinerea repre- 

 sents a form of this species suffused with gray, the transverse lines very 

 distinct. 



Wockci, of which scrojrnla.na, is a synonym, differs from carnea in the 

 form of the t. a. line which is very strongly dentate on costa and out- 

 wardly bent beneath internal vein. The S antenna'- are also entirely 

 simple and ciliate merely. In the form of the genitalia they also differ. 

 Carnea has no distinct clasper, but modified corneous harpes, curved, 

 and at tip furcate, the tines unequal. Woclici has distinct broad 

 harpes, and a clasper not unlike the side piece of carnea, the fork longer. 



AlasM', said by Mr. Grote to resemble carnea, really belongs with his 

 genns Agrotophila, and is an ally of montana. It is a very distinct 

 species, easily recognized by the yellow claviform which crosses the 

 entire median space. I have seen but one specimen, but recognized it 

 immediately.
