intervenular rounded lobes, that, in the middle of I he wing, are larger ; beyond, 

 on a luteous or pale-ochreous ground, is a row of acutely-triangular, black 

 spots, the one below the second median venule being acutely elongated, 

 lunate; a zigzag while line goes to the costa, marking a marginal, subapieal, 

 black, triangular space; Cringe long and blackish, interrupted with white. 

 Hind wings pale cinereous, a little dusky on basal two-thirds; discal dot 

 distinct; beneath, margin of wings paler, marked off by a quite distinct dark 

 line; near the apex on costa three narrow, black, parallel, longitudinal spots. 

 Legs dusky cinereous, ringed with whitish. 



Length of body, 0.35; of fore wing, 0.45; expanse of wing, 1.00 inch.

Very distinct, and easily, known by the black middle of the wing lined 

 with white; and by the black triangular patch just below the apex on the 

 outer margin, while the margin of the wing is luteous, interrupted with 

 acutely triangular black spots, and the head, tip, and upper side of palpi are 

 also luteous.

2 $ . — This fine species belongs near P. albollneata, but is much larger, 

 though in the form of the head, palpi, antennas, and wings it is nearly the 

 same. The ground-color of the body and wings is blackish-brown. Head 

 yellowish-white on the vertex and at the tips of the palpi. Thorax with 

 three linear, whitish stripes. Abdomen ringed with white, and the anal 

 tuft tawny-white. Fore wings blackish-brown, with an inner line directed 

 obliquely outward and bent at right angles on the internal vein, where it 

 touches the second double line, which is parallel to the basal as far as the 

 bend in the latter, thus inclosing a large, square, black patch, one side of 

 which rests on the costa, while there is a triangular dark spot on the inner 

 edge of the wing; the middle of the wing is occupied by a large square 

 patch connecting with a round patch on the inner edge, this round spot 

 being nearly cut off from the black patch by the points projecting from the 

 two opposite lines; the outer (extradiscal) line forms a nearly rectangular
