The Morphology of the Penis in the Genus Libellula 



(Odonata). 1 



By CLARENCE HAMILTON KENNEDY, Ohio State University, 



Columbus. 



(With Plates II and III.) 



The writer has just recently undertaken to trace out the 

 phylogeny of the genus Libellula through a study of the penes. 

 In this study it was found that this organ was more complex 

 and varied than was generally supposed. It was found that 

 the internal anatomy of the penis was different from the previ- 

 ously published ideas on the subject. This article will confine 

 itself to the morphology of the penis and the honiologies of its 

 parts, while the phylogeny of the genus will be dealt with in 

 the second article. 



The leading articles on this subject are by Rathke, Goddard, 

 Thompson, Schmidt and Bartenef. 2 Except the last author,
