even examples. The receipt of an example from Professor Piper 

 which was yet larger, darker and more even in color, induced me to 

 reexamine the series and to dissect out the genitalia. The new species 

 is uniformly larger, darker and even in color, without mottling and 

 with the terminal space not lighter than the ground, though in one 

 case somewhat lighter than the s. t. spaces. 



Carneades masculinus, sp. nov. 



Ground color a dull leather brown, lighter or darker, with smoky or blackish 

 shadings. Head ranges from brown to purplish-gray, with a darker line across the 

 front. Collar light brown or gray inferiorly, to a transverse black line which is more 

 or less obviously bordered on both sides by white scales : upper part of collar con- 

 colorous with thorax, sometimes tipped with brown. Thoracic disc ranges from 

 brown to purplish-black, the edges of the patagice sometimes relieved by white scales. 

 Primaries with costal region, to the t. p. line yellowish, grayish or whitish, always 

 contrasting with the rest of the wing ; median vein white to the end of the cell. 

 Basal line barely indicated by geminate dots on costa. T. a. line indicated in the 

 same way, and, in some examples, by a slightly paler line in the submedian inter- 

 space. T. p. line defined only by the difference in shade between the darker median 

 space, and the lighter s. t. space ; as a whole evenly outcurved over the cell 

 and almost evenly oblique below. S. t. line very irregular, defined only by the 

 contrasting darker terminal space and by a series of 3 or 4 preceding, more 

 or less sagittate marks : the terminal space completely cut by pale rays on veins 

 3 and 4. A blackish terminal line and a pale line at the base of the fringes, 

 which are of the darkest wing color. A black shade line from base through 

 submedian interspace carries the narrow, black-filled claviform. Orbicular round, 

 small or moderate in size, black-ringed, annulate within this ring by whitish 

 scales, the center brown ; occasionally the upper margin of the spot is cut by the 

 pale costal area. Reniform moderate, kidney-shaped, margined by black scales 

 within which is a whitish annulus : center brown. The cell before and between the 

 spots is black or blackish. The internal margin is of the brown or lighter ground 

 and, above this, the median space is dark to the median vein, cut only by the paler 

 shade accompanying vein 2 ; but the amount of contrast between the shades varies. 

 Secondaries of the male white or whitish ; the veins, a discal lunule, a terminal line 

 and the apical area a little smoky. Beneath, primaries gray, powdery, with a 

 poorly marked incomplete extra-median line and discal spot : secondaries whitish, 

 powdery along the costa, with a dark terminal line and discal spot. Expands 

 1. 20-1. 44 inches = 30-36 mm.

 1-15, Poling. 



Seven examples, all males, and four of them decidedly ragged. 

 The species is stout, comparatively short-winged, with proportion- 

 ately very heavy thorax, and belongs in a general way with furtivus
