HESPERIOIDEA OF A^IERICA 45 



appe^irs that there is no closer bond between aJpheu^ and libya 

 than between libya and catulliis, while ceos varies in the opposite 

 direction from catidlus but in the structure of the palpi shows 

 some afiinity with the first two species. For these reasons I 

 prefer to regard the group as one genus with a wide range of 

 structural variation. In this sense Pholisara may be character- 

 ized as follows: 



Palpi exceeding the front by the length of the head or more ; 

 second joint oblique, rather long, with moderate scaly vestiture ; 

 third porrect, slender, long. Antennae about one-half as long 

 as primaries: club more or less tapered and blunt. "VTings 

 rounded : secondaries with or without a slight indention lq the 

 outer margin at the end of the cell and sometimes with a slight 

 lobe at the anal angle. Xeuration variable ; vein 11 of primaries 

 never much beyond middle of cell and vein 2 about the same 

 distance from base of cell and vein 3 ; U. D. C. long, over half 

 the length of M. D. C. Male with or without costal fold, never 

 with tibial tuft. Fig. 13.

3. Under surface pale, yellowish; upper surface of primaries with trans-

Under surface usually less pale and with numerous white spots when 

 upper surface is heavily spotted; possibly not distinct from the pre- 

 ceding libya
