obsolete, except through tlie costal region. Basal line geminate, marked through 

 the darker portion of the hasal space. T. a. marked l)y smoky Innules over the 

 costa and in the cell, else obsolete. T, p. line smoky, marked over tiie costal 

 region only. An angiilated median shade is variably distinct, starting obliquely 

 outward from the costa to below the reniform, which it stains inferiorly, there 

 bent and inwardly oblique to the margin. S. t. line black, outwardly diffuse, 

 very irregularly dentate; inwardly oblique from below the apex, inwardly den- 

 tate in the interspaces and outwardly on the veins, two long outward teeth on 

 veins 3 and 4. reaching the outer margin, the inward tooth in the subnicdian 

 interspace sending in a long black spur, reaching the apex of the claviform. A 

 series of black, terminal lunules, and a pale line at base of fringes. All the 

 veins are more or less evidently black marked. The clavifcrni is long and nar- 

 row, extending from the base to the middle of the wing, concolorous or some- 

 what paler, margined more or less completely by black scales. Orbicular small, 

 oval, oblique, concolorous, more or less obviously black-ringed. Keniform large, 

 uprigiit, somewhat excavate outwardly, black-ringed, within which is a white 

 annulus, centrally with a luteous stain which invades the cell. Secondaries 

 white, a little fuscous powdered toward the outer margin and with an obvious, 

 though broken, smoky terminal line. Beneath white, sparsely black powdered, 

 with a smoky terminal line on all wings. Expands 38-41 mm.; 1.52-1.65 inches.

Two specimens, S and 9 , •» very good condition. Tiie female 

 is the larger, more wiiite, with the raaculation the more contrasting. 

 From the descr ption I thought that this might be P. cedon Grt., and 

 indeed tiie type of maculation is very similar. In the new species 

 it is much more contrasting, however, almost as clean cut as in epi- 

 chy-'<is or theodori, than which the new species is smaller. Unlike 

 these others, the antennae of the male are pectinated, as in illepida, 

 which, with the same general type of maculation, has an even dark 

 gray ground color and very distinct median lines. 



I*<»lia COUta<liiia n. sp. (PI. iii, fig. 1)— Ground color of head, thorax and 

 primaries white, with a bluish tinge and with black markings and i)owderings. 

 Palpi smoky; head in front with a black transverse line, and a black line be- 

 tween the antenna;. Collar with a broad, median, black line, black tipped at 

 the base of the well-marked anterior tuft. The disc narrowly black centered, 

 the patagiffi with a narrow discal submargin and a broad black line at the base 

 of the wings. Primaries to the t. a. line mottled with black scales, a short basal 

 streak in the submedian interspace, and another along the inner margin. Basal 

 half line distinct, geminate, the outer line with a broad outward angulation. 

 T. a. line geminate, distinct, quite evenly oblique outwardly, the inner line in- 

 terrupted and fragmentary, the outer emphasized by the dark filling of the me- 

 dian space. T. p. line geminate, the outer line consisting rather of a jwwderv 

 shade, tiie inner better defined, crenulate beyond the cell and with a long in- 

 ward tooth or sinus in the submedian interspace, cutting nearly through the 

 median space. This latter is blackish smoky, except on the costa, where it is 

 broken by white spots, and in the cell, where the ordinary spots are white and
