subquadrate spot, angulated outwardly, from apical part of costa 

 to veins 5-4, and another broader blotch similarly notched at 

 •outer edge, restuig on internal margin near angle, sharply pointed 

 at conjunction with vein 3. The interspace between veins 3 and 

 4 as well as the anterior margin is entirely immaculate white. 

 Apical blotches either wanting or minimal; a narrow terminal 

 line; small basal dots from costa to internal margin. Secondaries 

 light yellow; no discal dots, but large transverse dots of steel- 

 blue in basal part of cell, and from one to three submarginal dots 

 of same color. Below, the maculations of primaries are more 

 reduced, only two stalks from costa, which converge in cellular 

 interspace, the stalk riearest base wanting. The large subovate 

 blotch in basal half on internal margin, more or less obsolete. 

 Basal dots absent; secondaries as above. 



Hab. — Western Colorado. Caught by Mr. D. Bruce in several 

 •examples. Types in Mr. Neumoegen's collection. 



Var. opulenta Hy. Edw. 



As originally suggested by the describer, this must be only a 

 variety of caja. It is distinctly led up to by the form described 

 above. 



Genus ZATREPHES Hub. 



Head rather small, front higher than wide, narrowing a little 

 below, smooth, slightly convex; ocelli present, eyes large, glo- 

 bose, naked; antennae inserted over the eyes, very far apart, 

 simple, minutely ciliate; palpi exceeding the front by more than 

 half their length, ascending; tongue long, strong, coiled. Tho- 

 rax as long as broad, with smooth vestiture of hair and scales. 

 Abdomen moderately stout, exceeding the secondaries; the ter- 

 minal joints conical. Legs slender and closely scaled, long, 

 subequal; posterior tibiae with two pairs of short spurs, tarsi very 

 slightly spinuated with two claws at tip; fore wings produced at 

 apex, costa slightly and evenly convex, outer margin very ob- 

 lique; wing more than twice as long as broad; vein i free, sub- 

 sinuate, median four branched, veins 3-5 arising very close to- 

 gether and remote from 2; cell closed, the cross-vein deeply bent 

 inwards below the middle, the upper part oblique; 6 from apex 

 of cell; 7-10 on a stalk from origin of 6, vein 10 running very 

 close to the others; 11 arises from the subcostal and is also much 

 crowded in the narrow costal space; 12 free, with a loop near 

 base below to receive the frenulum of secondary; hind wings tri-
