liarpes are uir..sually long, the tip siuuate and inwardly prolonged. 

 It is fringed with the usual row of spinules, and has also a small pad 

 of short, stitf bristles at the inside of the extreme tip. 



Marinitincta is, comparatively, a very constant species, with always 

 a reddish tint to primaries. This repl.ices the green tint of laiulahUis 

 and is the only superficial feature 1 have been able to discover which 

 will separate the two. The genitalia, however, are different. The 

 harpes are not so long, are only slightly dilated at tip, not sinuate nor 

 so much produced inwardly, and without the pad of spinules. All the 

 specimens with the reddish suffusion have this structure, and all the 

 greenish, no matter how like they may be in details of maculation, have 

 the one before described. There is also a peculiar fascies, impossible of 

 descri|)tion, which separates the two. 



Alhoguttata is distinct. The even, fusco-luteous tint, appearing as 

 though there was a layer of dark over the ground layer of yellow scales, 

 and the prominent white median lines, are characteristic. The male gen- 

 italia are verj' like those of m<irinitincta ; but the clasper is somewhat 

 thickened before the tip, and the position, though not the shape, of the 

 harpes is different. There is no confusing this with any allied form. 



Cuneata is rather larger and broader winged than any of the pre- 

 ceding, with much more constancy in color and maculation. It is rather 

 dark ash-gray, the maculation all distinct, though not contrasting. The 

 s. t. line is marked by a distinct yellow dot near hind angle, and an 

 irroration of yellow scales beyond the reuiform is evident in all well 

 preserved specimens. The vestiture is somewhat rough, and the wings 

 are somewhat broader than those of any species save lorea, which are 

 referred to this group. It is not easy to mistake, though brachiolum of 

 another group may be confounded with it. The genitalia differ from 

 those of the preceiliug in the more gradual enlargement and larger 

 lappet-like tip, which is truncate and slightly sinuate. The clasper is 

 rather longer and more hook-like; but altogether the species belongs 

 where 1 have placed it. 



The following table will assist in identifying the species: 



Secondaries white ia both sexes. 

 Dark gray, evenly colored; t. p. line strongly incurved below reniform, even in 



course ixcikva. 



Variable, more or less contrasting; t p. line liiuulate, evenly oblique or sinuate, 



not incurved below rcnilorm 4-Ll^■EATA. 



Secondaries dusky in both sexes, 

 rriniuries green, gray or blackish. 

 Median space darker. 



Pale gray, with a faint reddish suffusion marinitincta 



Green; median space varying from red to black l<vudabius. 



Median space not darker. 



Median lines and ordinary spots contrasting, white marked alboguttata. 



Median lines and ordinary spots not white nor contrasting ; s. t. line with a 



yellow spot near hind angle CCNEata. 



Primaries reddish yellow or dark luteous; median lines single, brown, distinct ; 



median space usually darker lokka.
