the costa is not concave. The terminal space is indented on veins 

 3 and 4 by pale streaks on those veins, and it therefore belongs to 

 the 4:-dentata group of the genus. In the specimens before me there 

 is some difference in the amount of the indentation, but it is distinct 

 in all cases, and the s. t. line itself is in some cases scarcely visible. 

 The antennae are really shortly pectinated rather than serrated, the 

 short branches furnished with bunches of bristles. As it appears 

 now, this species might head the series following immediately after 

 the wihonii group. 



Caruoades lietificans n. sp. (PL iv, fig. 3) — Ground color a smoky red- 

 browu. Collar at base gray in the female, yellow in the male, in both cases 

 limited above by a black line, above which the ground color obtains. Thorax 

 concolorous, the edges of the patagire a little lighter. Primaries with the costal 

 region to the t. p. line yellowish in the male, gray in the female, the regi.on 

 along the internal margin also lighter than the remainder of the wing, but not 

 so pale as the costal region. The cell is black filled before and around the ordi- 

 nary spots. Basal line traceable as a pale dot in the black basal dash below the 

 median vein. T. a. line marked as a pale line through the dusky region below 

 the median vein, the pale color a little defined by a few black scales. T. p. line 

 marked only by the contrast between the dark central portion of the median 

 space, and the paler s. t. space. S. t. line marked only by the conti'ast between 

 the pale s. t. and dark terminal space. This dark terminal shade does not ex- 

 tend to the apex, and is quite strongly indented on veins 3 and 4 A series of 

 black terminal luuules, followed by a pale line at the base of the fringes. Median 

 vein white to the end of the cell. A black basal dash extends to the t. a. line, 

 beyond which the claviform is attached in the form of a small black loop. Or- 

 bicular oval, oblique, open to the costa, white or yellow ringed, with dusky centre. 

 Eeniform of good size, kidney-shaped, white ringed, with a gray centre. Sec- 

 ondaries white in the male, smoky in the female, in each case the veins and an 

 outer liiie darker, fringes again paler. Beneath whitish. Primaries smoky out- 

 wardly, secondaries powdery along the costa. lu the female there is an incom- 

 plete outer line on the primaries, and a distinct discal spot on the secondaries. 

 Expands 32.5-34.5 ram. ; 1.30-1.38 inches.

This species is an ally of segregata, than which it is much darker ; 

 yet with exactly the same pattern of maculation. I considered the 

 pcssibility of their being local forms of the same species until I found 

 that in this type the male antennre are distinctly serrate only and 

 not shortly pectinated as in the other. There is quite a difference 

 between the sexes, as the species is represented in my hands; but it 

 is scarcely likely that this same difference will be equally marked in 

 the general run of the specimens.
