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 militaris 

 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 contigiia. 



H. militaris flies from June loth to 2oth, the yellow form (ff. 

 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 t Group Aeschna.
