Smoky or blackish, both wings with a broad white margin, which is 

 buff-shaded outwardly. Primaries with a basal, curved, white band and 

 an oblique white band from near apex to inner margin ; the subcostal 

 and median veins are white between the white bands, and sometimes 

 all the veins are more or less white marked. A light carmine dash ex- 

 tends from the outer white line on vein 7 to apex ; above this, shading the 

 line outwardly, is a black patch, marked with blue scales. At the end 

 of the discal cell is a large black ocellus with a narrow vitreous center 

 and rings of black, yellow, black, blue and black, the blue riug being 

 usually on the inner portion only. Secondaries with an indefinite broad 

 and white basal band and an outer more distinct white band, running 

 parallel to the outer margin. An ocellus at end of cell, similar in all re- 

 spects to that of primaries. Beneath with the outer margin, apex, and 

 ocelli reproduced as above. Basal band obsolete, outer band a narrow 

 waved white line. The specimens vary much as to amount of white in 

 the wings — sometimes the color is mostly blackish and the markings 

 are limited, while in other specimens the white invades the whole wing — 

 especially the secondaries are occasionally white from outer band to 

 base. The males as a rule are smaller and whiter than the females. 



Expands 2.2o-2.G0 inches. Hab. Texas, Arizona. 



Rather a rare species. The larva is unknown so far as I am aware, 

 though the cocoon has been superficially described by Mr. Geo. D. Hulst 

 in a communication to the Brooklyn Ent. Soc, published in proceedings 

 of the society in " Entomologica Americana." It is readily known by 

 its white and smoky black colors and the carmine dash at the apex. How 

 it compares with the European species of Saturnia I cannot say at 

 present. 



CALOSATURNIA, u.geu. 



Head very much retracted ; eyes small, narrow, ovate ; tongue and 

 palpi entirely aborted ; vestiture thin and divergent. Antennae of $ 

 with two branches to each side of each, joint, as usual, the pectinations 

 extending to the tip. In the female the antennae are stout, shortly" pec- 

 tinateel to the tip ; a single branch only to each side of each joint. 

 Body vestiture hairy, thin, divergent, the thorax comparatively short. 

 Legs short and weak, the i)osterior pair shortest and weakest ; no vis- 

 ible spurs to any pair of legs. Genitalia of S very like tUose of Sa- 

 turnia, save that the points of supra-anal plate are not so diverging and 

 not so acute. The side pieces are essentially the same. Primaries with 

 but nine veins, 5 and G together from the ui)per end of the cell ; 7 and 

 8 on a long stalk from the subcostal. The venation of the secondaries 

 is as in ISaturnia.
