indistinct. T. a. line nearly straight, with a deep tooth anteriorly 

 pointing toward the base. T. p. line dentated, outwardly joining the 

 reniform in a darker eloud. Marginal line lost in a row of dark clouds. 

 Intronervule spaces, pointed with black lunules. The basal, median, 

 and snbniarginal spaces are pale by contrast with the dark lines. 

 Lower wings a dull stone drab, a little paler toward the base. Under- 

 side uniform stone drab, with very distinct darker discal spots and a 

 median baud common to both wings. Margins also dark. Thorax and 

 abdomen coucolorous. Exp. wings 32 mra . One female, two males.

This species is a distinct one, but 'having no specimens at hand, I 

 can not place it exactly. I give, therefore, Mr. Edwards's original 

 description, which will be sufficient to enable the species to be recog- 

 nized.

Eyes hairy, tibiae uot spinose.or in any way armed. The body is 

 plump, stout, rather densely clothed with hairy or mixed vestiture on 

 thorax, forming a more or less obvious divided anterior crest and dis- 

 tinct posterior tuft. Abdomen rather elongate, slender, uutufted. Head 

 somewhat, or considerably retracted, the palpi well developed, reach- 

 ing the middle of front. Primaries rather small, short, trigonate, with 

 marked apices and oblique outer margin. The genitalia are practically 

 alike, differing only in minor details. The harpes are narrow, slender, 

 elongate, subequal, terminating in an obliquely rounded tip, which is 

 inwardly furnished with long spiuules. The clasper is long, slender 

 and curved, subequal throughout, and obtuse at tip. The male anten- 

 nae are simple. 



Three species are referred to this genus. Niveiguttata, which differs 

 from others by the more retracted head, plump form and small wings, 

 is also easily distinguished by the distinct geminate white spot on disc 

 of primaries just beyond and touching the inferior portion of reniform. 

 There is no possibility of mistaking this species. 



Modesta and fasciata are closely allied, less robust, and with some- 

 what more ainple primaries. They agree also in the type of maculation : 

 in both, the outer portion of median space being darker, somewhat V- 

 shaped. In fasciata, however, the contrast is great, glaring, the large 

 yellow reniform adding to the definition and distinguishing the species, 

 while modesta is a quiet mouse-gray form, with no strong contrasts of 

 color, and coucolorous or slightly darker reniform. 



Like most of the surrounding genera, this has no prominent distin- 

 guishing feature, unless the genital structure is so regarded. The hab- 

 itus, wing form, and proportions of body combine to form the necessary 

 generic characters.
