to find a single example of the immaculate form flying with 

 the contigua. 



It is interesting to note that while contigua is never found in 

 the east woods (where I take the militaris) nor is jnilitaris 

 found in the west woods (where I take contigua), yet the only 

 H. lecontei I have ever taken locally was taken in the west 

 woods flying with the contigua. 



H. militaris flies from June loth to 20th, the yellow form (i/. 

 dyarii) flying with them, but the H. contigua does not appear 

 until about July io-2oth). H. clymene appears in the east 

 woods about July i-io, after militaris are gone, but does not 

 appear in the west woods. 



The colored boys (Nos. 95-96) were so named from their re- 

 markable resemblance to the human figure, when the wings are 

 folded at rest. 



A series of this variable genus, even from one locality, would 

 in a few years' collecting become quite interesting, while if 

 formed by exchange from different localities widely removed, 

 would become intensely so. 



A proposed new genus of Odonata (Dragonflies) of 



the Subfamily Aeschninae, Group Aeschna.
