Vibex is intermediate between it and brettus but at present I am not pre- pared to agree with Dyar's suggestion that they are all the same species (Jn. N. Y. Ent. Soc. xm, 128, 1905). Godman and Salvin make stigma synonymous with vibex (Biol. , Rhop. II, 480, 1900). 13. POLITES CHUSKA Eesperia clmsTca Edw., Trans. Am. Ent. Soc. iv, 346, 1873. I know nothing of this species. It is placed between sabuleti and draco in Barnes and McDunnough's Check List, but this was done merely with a knowledge of the description. The type locality is Arizona. Genus CATIA Godman & Salvin Catia G. & S., Biol. , Rhop. n, 481, 1900. Type Hes- peria drwryi Latreille. Catia is structurally similar to Polites but differs in the long slender apiculus of! the antennae, which always exceeds the diameter of the club, and in the form of the male stigma. The stigma is com- posed of a velvety black patch below the end of the cell and a similar patch above the inner third of the anal vein, with Fig. 26. cam otho a. & s. a. large, silky, gray scales between. In the Club of antennae' b' Neuration bleached wing it appears as two similar oval spots, one on each side of vein 1. Fig. 26. In describing Catia Godman and Salvin say of the peculiar structure of the stigma that it "is so remarkable that we think it of sufficient importance to put the species possessing this char- acter into a separate ; Otho is closely related to the species now included in Polites and was formerly associated with some of them in Thymelietis,
