sometimes a paler central shade ou the disk of the thorax. Primaries with all the 

 ordinary maculation obscured l)y the dark powderings, and yet all of it traceable, 

 liasal line geminate, wanting in dark specimens, fairly detined in the others. T. a. 

 line geminate, the inner line vague, the outer outcurved between the veins, as a 

 whole upright or A'ery slightly oblique. T. p. line geminate, the inner line most 

 evident, feebly crenulated, outcurved over the cell, and rather evenly oblique below. 

 S. t. line a pale irregular shading near the outer margin, variably distinct in the 

 specimens before me, and in one case well defined by a darker preceding shade. A 

 series of dark interspaceal terminal lunules, followed by a pale line at the base of 

 the fringes, the termination of the veins somewhat emphasized by the same color. 

 There is an indication of a vague median shade line, most marked between the ordi- 

 nary spots, where it darkens the cell. Claviform faintly indicated in some, wanting 

 in other specimens. Orbicular round, concolorous, very feebly marked in most 

 instances. Reniform moderate in size, npright, kidney shaped, sometimes defined 

 by a narrow black line, sometimes only by a vague dusky shading, usually a little 

 darker centered. Secondaries soiled whitish at base, smoky outwardly, with a fairly 

 marked dark line at the base of the pale fringes, and a variably evident, never well- 

 marked discal lunulo. Beneath whitish, variably powdered with dark scales, form- 

 ing a discal lunule on one or both wings, and sometimes an outer band as well.

Four Specimens, tliree of them males, are uuder consicleratiou, and 

 others not differing are in the National Museum. While all the speci- 

 mens look very much alike in general appearance, no two agree in 

 ground color nor in the distinctness of the maculation. It is one of 

 those obscurely marked forms characteristic of the genus to which I 

 have referred it, and which it is exceedingly difficult to characterize 

 satisfactorily. It differs from the congeneric forms by the powdery 

 luteous ground color and the fragmentary and obscure maculation. 



Oncocnemis flagrantis, n. sp. (Fig. 46, 9).— Ground color a peculiar rusty luteous, 

 varying in shade. Head and collar immaculate. Thoracic disk svith gray and black 

 scales intermixed, the patagia margined with the same mixture. Primaries with 

 the markings sordid black, the median space densely pow^dered with black scales, 

 through which the ground color ai>pears at irregular intervals. Basal line diffuse, 

 single. T. a. line vaguely detined, geminate, the inner line consisting of irregularly 

 disposed black scales, the outer indicated only by the dark median space as a whole. 

 T. p. line defined by a series of irregular spots of the ground color to the submedian 

 vein, up to which point the dark shading extends to the s. t. line; below this the 

 contrast between median and sub-terminal spaces indicates the line. S. t. line irreg- 

 ular, marked by the difference between the s. t. and terminal spaces to the sub-median 

 vein, below which it is obsolete to the inner margin where it is again indicated by 

 a few black scales. A series of dark, interspaceal terminal dots, beyond which the 

 fringes are cut by a dusky line. The fringes are long, of the ground color, with a 

 dusky interline, and cut as above described in the interspaces. The claviform is 

 traceable, centered with the ground color, margined by a somewhat more compact 

 massing of darker scales. Orbicular small, round, distinct, of the ground color, with 

 a dark central dot. Reniform large, of the ground color, indefined and sometimes 

 black powdered. Secondaries a sordid yellowish white, the veins and an indetermi- 

 nate outer band smoky or blackish. Beneath dull yellowi.sh, powdered, sometimes 

 with the disk of primaries darker, and ou secondaries with aji obscure punctiform 

 outer line.
