Our knowledge of the characters of the various forms referable to 

 this genus is so defective that we have detailed at length the whole of 

 the synonymy that may probably be referred to the genus, i.e., 

 including the eastern Asiatic and American forms, so that students 

 who wish to go into the matter more deeply may find here means of 

 ready reference to the literature. We had at first made up our mind 

 to include most of the Asiatic and all the American forms under the 

 specific name "argiades," but, Chapman's work with the genitalia has 

 led us to modify this procedure. We propose, however, to deal with 

 most of them, but not at so great length. In the present state of our 

 knowledge the species that certainly belong to Everes appear to be E. 

 argiades, Pall., E. alcetas, Hoffmansegg, and E. dipora, Moore, and 

 probably some American species allied to E. comyntas and not yet 

 described. 



Having thus stated that very little is known of the small, deli- 

 cately-tailed insects that are comprised in the genus, and that the 

 species are by no means capable of very clear differentiation, it will be 

 readily understood that, so far as the genus is concerned, its limits are 

 strikingly curtailed and the generic elements peculiarly homogeneous.
