cliiced ; the outer portion of the Clasper is less prominently angled, 

 the right Harpe is shorter, the left one better developed than in trifolii 

 and the whole organ slighter and less strongly chitinized ; both gray 

 and reddish forms are identical in this respect. The species might at 

 first sight be confused with (jatci Sm. from the same locality, which 

 has, however, much paler secondaries and darker primaries and a 

 prominent angle opposite cell in s. t. line filled in with dark shading; 

 the genitalia of these two species are very different, gatci (Plate IV, 

 fig- 3) representing an entirely ditlerent group in which the extremity 

 of the clasp is rather squarely cut, not rounded, and the ])ad of hair 

 replaced by a few spines. 



SCOTOGRAMMA CASTRAIi sp. UOV. (Plate I, fig. II.) 



Head and thorax clothed with a mixture of ochreous, pink, and black 

 scales, the latter tending to form a transverse line on the collar and lines on 

 the patagia ; primaries brown suffused with pink, giving a general reddish 

 appearance to the wing ; maculation prominent and contrasting ; basal line 

 black, geminate, filled with pinkish, the outer line obsolescent, inner line prom- 

 inent, joined to base of wing by a short black curved line ; t. a. line black, 

 geminate, shghtly crenulate, outcurved to submedian fold, then straight, filled 

 with pinkish; claviform variable in size, at times small and filled with black, 

 mostly large, broad and blunt, outlined with black, filled with the ground color 

 or else shaded heavily with black, forming a prominent dark patch below the 

 pale orbicular ; orbicular moderate, round, outlined in black, shghtly open at 

 top and bottom, filled with pinkish with faint dark central shade ; reniform 

 large, upright, broadening slightly in lower half, with pink anmdus and dark 

 central filling, outlined in black, the basal margin much more heavily than 

 the remainder, this portion tending to enlarge to a lunate pat.-h ; a narrow 

 median shade line, oblique from costa to base of reniform, dentate in the 

 lower half ; t. p. line not very prominent, geminate, black, filled with pinkish, 

 the outer line rather obsolete, crenulate, sharply pointed on the veins ; s. t. line 

 one of the most characteristic features of the maculation, pink, connected be- 

 low costa and angled outwardly, then breaking up into a series of triangular 

 pink spots, shaded inwardly with black, forming a scries of arrow-like marks 

 whose apices point toward base of wing ; outwardly the s. t. line is very slightly 

 shaded with black ; a terminal series of black lunules ; fringes mixed dusky and 

 pink, crenulate, the hollow portion partially filled with a black dot; a pale 

 basal fringe line. Secondaries ochreous overlaid with smoky, most heavily 

 outwardly so that a broad dark poorly defined marginal band is formed ; a dark 

 discal dot ; fringes pinkish crossed by a broad dark smoky line. Beneath 

 ochreous, sprinkled with pinkish-brown; both wings crossed by a diffuse 

 smoky subterminal band broadest on costa of primaries and preceded by traces 

 of a postmedian line ; a large discal spot on primaries and a smaller one on 

 secondaries ; fringes as above. Expanse, .33 nmi.
