paling gradually towards base which is white and slightly irridcscent ; fringes 

 white. Beneath S white with costal area of both wings sprinkled with gray ; 

 discal dot and faint postmedian line present on both wings ; 9 with more

Closely related to yakiiiia Sm. and orida Sin. in maciilation and 

 color of primaries; the secondaries are, however, as in [>tilodonta Grt., 

 lacking the distinct marginal banding of the above two species. 



ScOTOGR.\M.M.\ FERviDA sp. nov. (Plate I, figs. 9. 10.) 



Primaries varying from gray-brown to red-brown, sprinkled and shaded 

 with blue-black; maculation often indistinct, the ordinary lints being only 

 well marked on costa ; when present they are geminate and filled with a slightly 

 lighter shade than the ground color; basal line black, bent inward below cubital 

 vein and joined to base of wing by a slight black .streak; t. a. line straight in 

 course, crenulate in the interspaces ; t. p. line rather squarely exserted around 

 cell, slightly incurved in subcostal fold, crenulate, sharply pointed on the veins ; 

 ordinary spots distinct and prominent ; clavif orm a broad black loop of varied 

 length, usually not much longer than broad ; orbicular round or oval, variable, 

 outlined faintly in black and with an indistinct annulus slightly paler than the 

 ground color; reniform large upright, the lower portion broadening out and 

 prominently filled with blue-black, outlined with black ; s. t. line pale, angled 

 below costa, bent outward gently between veins 2 and 5 but with no distinct 

 W mark, at times shaded inwardly with short red-brown arrow marks ; terminal 

 space dark, heavily shaded with Idue-black ; terminal row of black dots ; fringes 

 smoky, cut slightly with ochreous opposite the veins and with ochreous basal 

 line. Secondaries pale with a broad poorly defined dark marginal band, rather 

 darker in 9 than in $ ; fringes pale, slightly tinged with rosy or ochreous 

 and cut by a dark subbasal line. Beneath pale, sprinkled along costa and broad- 

 ly along outer margin with smoky-brown which in the 9 tends to cover the 

 whole wing, tinged with rosy or ochreous towards apex of wings ; discal spot 

 and indistinct postmedian line on both wings, the latter better defined in 9 

 than in $ ; fringes as above. E.xpanse, 31 mm.

Is closely related to trifolii l\ott. and albifiisa Wlk. but can be 

 most readily sei)arated by the general rt)iigh and diffuse appearance, 

 the broad bulbous lower half of the reniform which is often prom- 

 inently filled with blue-black, and the even s. t. line with scarcely a 

 trace of the W mark. The genitalia (PI. I\'. fig. 4) are of the trifolii 

 type but quite distinct ; the prominent Gnath of trifolii is greatly re-
