Closely allied to Mamcstra moiitara Sm. from Yellowstone Park 

 of which 5 Paratypes are before lis. Differs in the brighter and more 

 contrasting coloration, the dotted s. t. line, and the broad basal black 

 margin of reniform; the terminal dark band of secondaries is also 

 not so distinct, the inner area being more heavily shaded with brown ; 

 our single $ specimen has lost the abdomen so we have been unable 

 to compare genitalia. 



Eriopvga catalina sp. nov. (Plate I, fig. 14.) 



9 . Palpi, thorax and collar pale ochreous ; thorax deep purple brown ; 

 primaries deep purple, shaded with ochreous and black ; maculation contrasting 

 and distinct ; basal line geminate, black, filled with ochreous and preceded by 

 slight ochreous shading; subbasal space shaded with black, forming a rather 

 prominent patch in the submedian fold ; t. a. line black, geminate, slightly 

 crenulate, outwardly oblique, filled with ground color and shaded outwardly 

 with ochreous; claviform a small black loop; orbicular small, defined in black 

 with pale yellow annulus and dark central portion; reniform large, upright, 

 slightly drawn out towards base of wing in lower portion, largely pale yellow, 

 shaded with darker scaling at base and containing a faint dark annulus ; beyond 

 and below reniform slight ochreous scaling and traces of an inwardly oblique 

 dark median shade line in lower portion of wing; between orbicular and reni- 

 form a velvety-black patch ; t. p. line geminate only at costa, bent outward 

 below costa. then inwardly oblique to inner margin, followed by several white 

 points and black dashes on the veins; s. t. line only distinct in costal half, de- 

 fined by deep black shading in subterminal space, angled sharply outwardly 

 below costa then straight to vein 4 where the black shading terminates in a 

 broad patch wliich extends nearly across the subterminal space ; above this 

 patch the subterminal space is darker purple than in the lower half; tcrniin \l 

 space dark, slightly shaded with ochreous and with a terminal row of pale 

 purple dots ; fringes ochreous shaded with dusky. Secondaries smoky with 

 ochreous fringes cut by a dark median line. Beneath primaries smoky, shaded 

 narrowly along costa and in terminal space with ochreous, veins outwardly 

 scaled with ochreous ; dark postmedian line and discal dot ; s. t. line of upper 

 side defined by contrast ; secondaries ochreous, shaded terminally with smoky 

 with broad postmedian line and small discal dot; fringes on both wings 

 ochreous. Expanse, 29 mm.
