414 ENTOMOLOGICAL NEWS. [NoV., '14 



Several individuals were seen, but all flew at once back into 

 the dense alder thickets, where the collector must follow often 

 on hands and knees, and where brush prevented the use of the 

 net even if approach to the wary and restless dragonfly was 

 possible. Add to these difiiculties the fact that the poisonous 

 and sluggish cotton-mouth snakes were common at the same 

 places where the Lestes occurred, and some idea of the labor 

 and excitement involved in the capture of these dragonflies 

 may be grasped. The two specimens I succeeded in collecting 

 are identical with specimens from the interior of Guatem.ala 

 (Gualan) taken under easier circumstances in June, 1909.
