118 MALE GENITALIA OF NORTH AMERICAN HESPERIIDAE 



17. Eudamus alcaeus Hewitson (Fig. 16.) 



Biologia, plate 75, fig. 12. 



We have specimens from Huigra, Ecuador (Rhoads), and 

 Williams has caught it in Vera Cruz, Mexico. It is another 

 species entering our fauna through the Runj''eon capture, which 

 is authentic. 



The male genitalia show a highly developed shagreened 

 scaphium, the cleft uncus terminals show a tendency only to 

 the short and spatulate condition obtaining in the following 

 species {melon), and the aedoeagus carries a branched spine 

 similar to that of proteus. We prefer to leave this species in 

 Eudainus.

 arizone.fisis. Baboquivari Mountains, Arizona. 



18. Codatractus melon arizonensis Skinner (Fig. 17.) 



The type and paratypes of the Arizona form (Poling) are in 

 the Academy Collection. 



The male genitalia show, as indicated above, comparatively 

 short, widely separated spatulate terminal projections to the 

 uncus. The aedoeagus carries a branched spine, which has the 

 forks leaving the stalk rather lateral than distal.
