broader shaded median line, inwardly oblique and a little arcuated, is 

 angulated on the cell outside of a black cellular eyelike spot which 

 shows some central metallic scales and is more or less completely 

 surrounded by a metallic iris prominently visible in certain lights. 

 The outer line is double, rivulous, angulated opposite the spot and 

 obsolete on costal region. Subterminal line double, rivulous, including 

 superiorly metallic scales above and below a subcostal indentation of 

 the line. Hind wings paler with double median and exterior lines 

 not continued to costa. Beneath the primaries show the black and here 

 larger discal spot with a yellow iris very distinctly, as also metallic 

 scales between the double subterminal line. Secondaries darker than 

 on upper surface, irrorate, with faint lines. Expanse .75 inch. 

 Hab. Pennsylvania. 



KOTE ON PAPII.IO GUNDIiACHIAXUS. 



BY A. R. GROTE. 



As compared with Machaon and Asterias the Cuban species differs 

 by the sinuate external margin of the fore wings while on the second- 

 aries the discoidal cell is much smaller and the nervules thrown off at 

 shorter intervals. The internal margin is folded in both sexes and in 

 the male is brought entirely over, while the surface of the pouch thus 

 formed is covered with whitish discolorous silky hair. The body is 

 ornamented with scarlet patches of velvety consistence as in certain 

 of the South American forms. I propose to make the species the type 

 of a distinct genus which I name Blakea after my friend Mr. Charles 

 A. Blake. Blakea differs by the metallic bands of the primaries which 

 in the tailed species known to me are opake.
