JOHN B. SMITH, SC. D. 347 



The males of all the species further agree in genitalic structure. 

 The supra-anal plate is of the usual triangular form, and the uncus 

 is a long, simple curved hook of the usual type. The harpes are 

 elongate, of moderate width, and drawn to a rather long point. 

 Along the upper margin they are thickened, and at or behind the 

 middle the corneous clasper is attached. This clasper is rather 

 short, stout, and divided into two forks or branches of which the 

 interior is somewhat hood-like, with a serrate extremity, while the 

 exterior, lying next to the harpes, is more or less spatulate, drawn 

 out and flattened. Within the limits of this series the agreement is 

 close and the species form a thoroughly natui'al little group. 



Verberata Smith is the darkest, and, in a way, the best marked 

 species. The ground color is a sordid luteous, more or less tinged 

 with reddish, mottled and blotched with smoky, and with a very 

 conspicuous, angulated median shade. The dull smoky secondaries 

 with broad costal and narrow exterior yellow margins are alike in 

 both sexes. The black color at sides of front noted Ijy Sir George 

 Hampson is really only a small margin in front of the eyes ; but it 

 is present and is characteristic. 



Bicolorago Guenee, with its more usual form ferruginoides Gn., 

 has a much lighter, more rusty yellowish ground color, the wings 

 seeming altogether more thinly scaled. The maculation is all 

 broken up and the shadings are purplish. The tendency is to 

 darken the entire outer half of the wing; the extreme is this direc- 

 tion being the typical though rather more exceptional bicolorago, 

 while the more common type in which the shadings are reduced to 

 the broken up lines is ferruginoides. The median shade is rarely 

 conspicuous in itself, and is not strongly angulated over the inferior 

 half of the reniform. The secondaries are very like those of verbe- 

 rata, except that they seem more thinly scaled and the light color is 

 paler, more reddish throughout. This is, perhaps, the most common 

 and widely distributed species of the genus. 



Decipiens Grote looks like a large, washed out ferruginoides with 

 yellow secondaries. The primaries are without contrasts of any 

 kind, and the maculation is traceable merely. 



Acta Smith is a bright species, in which the secondaries are uni- 

 formly bright lustrous yellow, almost transparent. The primaries 

 are a little darker in ground color and are marked and mottled with 

 brick-red ; sometimes approaching the appearance of ferruginoides.
