females from Texas in my collection are all teneral, and, in the 

 course of study, all the male superior appendages but one 

 have been lost. I am able to account for this only as a result 

 of their teneral condition which seems to make the appendages 

 extremely fragile.

Another individual, presumably of the same species, was 

 seen but not taken. The flight was very swift, and, though I 

 waited some time, the dragonfly did not return, nor were oth- 

 ers seen. In the brief glance I got of it, and, of the one cap- 

 tured, the effect was of a brownish or grayish insect, not at all 

 suggesting the Macromias I am better acquainted with in 

 Indiana.
