374 Ao'e Everes argiades and cor etas distinct species ? 



this area, glabrous in argiades, carries a considerable number 

 of hairs in coretas. 



The hooks or parameres of the dorsal piece (tegumen) are 

 longer and more slender in coretas, the terminal portion 

 though longer is not so sharp as in argiades, and the latter 

 has a large rounded flap at the base of this terminal 

 portion, that does not exist in coretas. The a^dmagus is 

 more robust in coretas, more slender in argiades. 



Amyntula is coretas in most respects, it is argiades in the 

 curvature, shortness and stoutness of the spiculation, of 

 the spinous process, and also in the rather more slender 

 soft-process. 



There is considerable variation in the size of the 

 appendages in both argiades and coretas. I have not 

 examined enough examples to assert that this corresponds 

 with the size of the insect or with the geographical 

 distribution.
