o2 TORTEICIDiE. 



the short apical joint depressed and exposed. Fore wings about twice as long as wide — with 

 the costa slightly arched ; apex rounded ; apical margin oblique, slightly convex — brownish, 

 with a purplish gloss on the basal half, more pinkish on the apical half of the wing, much 

 mottled throughout with irregular purplish-fuscous spots and bands ; an irregular dark 

 fuscous-brown central fascia, with a projecting excrescence about the middle of its outer edge, 

 with a slight sinuatiou on either side; an ill-defined brownish-fuscous basal patch, with 

 a purplish spot near the base of the dorsal margin ; a conspicuous semilunar brown spot, out- 

 wardly margined with fuscous, lies between the end of the cell and the apex ; above it is 

 a bright ferruginous narrow band along the costa, passing round the apex and along 

 the apical margin to the anal angle, separated from the rather fuscous cilia by a slender line. 

 Type c? • Expanse of wings 15 millims. 



North America. From Mr. Carter^s collection. Also in Shasta County, California, 

 July 1871. 



Riley gives seeds of Tigridia as the food of the larva. Mrs. Treat reared it from buds of 

 Ve7'bena.

Sericoris vetulana. (Plate LXVII. fig. 9.) 



Palpi projecting about the length of the head beyond it, roughly clothed, the long scales 

 below projecting as far as the end of the exposed apical joint ; these, together with the head, 

 antennae, and thorax (which is tufted behind), cinereous brown. Fore wings more than twice 

 as long as wide — the costa arched ; the apical margin scarcely oblique — greyish cinereous, with 

 a brown fascia from the middle of the costa, not reaching the dorsal margin, and having an 

 excrescence on its outer edge, the whole having the appearance of an inverted chess-knight ; a 

 brown triangular spot on the dorsal margin before the anal angle, sometimes joined to a second 

 brown shade or blotch below the apex, which tends obliquely towards the apical margin : some 

 few brown abbreviated streaks from the costa, a very ill-defined sometimes obsolete basal patch, 

 and a brown line along the apical margin at the base of the cilia, which are cinereous. Hind 

 wings rather brownish; cilia paler. 5 ^ . Expanse of wings 15-17 millims. 



Northern California, early in June 1873, also from Texas.
