that Urbicola Barbut (Linn.) takes precedence over Pamphila Fabr. 

 but we hesitate to use this generic name as there seems some doubt 

 among European authorities as to its validity; we note Tutt's proce- 

 dure, however, and would leave the matter for the present open. With 

 regard to the position of the genus we incline to placing it imme- 

 diately following Clvaerephon G. & S. ; the short point of the antennal 

 knob would point to this association.

According to the type 5 's from Texas in the Edwards' Collec- 

 tion this would appear to be distinct, at least as a race, from seminole 

 Scud. ; in the Texan form the underside of the hind wings is yellow- 

 ish green whilst in the Florida form (seminole) it is dark blackish- 

 brown. The type of maculation is the same but the $ 's of attains 

 seem to have a greater extent of the yellow area on the upper side 

 than is found in seminole; a $ presumably of this species from Black 

 Jack Spgs., Texas before us agrees with Scudder's figure of attains 

 (Butt. N. Eng. Ill, PI. 17, Fig. 12).

This seems better placed in Pamphila, as the shortness of the 

 point of the antennal knob and the shape of the $ stigma distinctly 

 point in this direction ; it is in some things intermediate between the 

 two groups.

In view of the fact that Scudder's type specimens of the various 

 varieties described by him in 1874 (Mem. Bost. Soc. N. H. Vol. II, 

 No. 4) are from widely divergent localities it would seem well to 

 restrict each form to a single one of these localities. Nevada the first 

 variety described is listed as from South Park, Colo. (Mead) and 

 also California, Nevada and Oregon ; the $ 's figured are all from Colo- 

 rado (Mead) and the figure of the genitalia is also taken from a 

 Colorado specimen ; we would therefore restrict the type locality to 

 S. Park, Colo, and Fig. 1 of PL X (Colo., June 12th, Mead) may be 

 taken as that of the type, which on a recent visit to Cambridge we 

 were able to pick out of Scudder's material. 



Colorado was described from specimens from Georgetown and S. 

 Park, Colo. (Mead) and Arizona (Wheeler) ; the figured specimens 

 and the specimen serving for the slide of the sexual organs are all from 

 Colorado so we may regard Fig. 18 (Colo. July 13, Mead) as that of
