Family Gomphidae. 



Herpetogomphus designatus Hag. July. 



Gomphus militaris Hag. July. The remarks by Dr. L. O. Howard concerning the 

 identification of the single male specimen are as follows: "This specimen was 

 sent to Dr. Philip P. Calvert of Philadelphia, for verification of the determina- 

 tion, since we had no specimens of that supposed species in Washington and 

 could not be certain of its identity from the description. Doctor Calvert reports 

 that he has compared it with the specimens of Gomphus militaris in the Academy 

 of Natural Science, which were some years ago compared with Doctor Hagen's 

 type of that species in the Museum of Comparative Zoology. He states that 

 as a result he believes your specimen is also militaris, for, although there are 

 some slight differences, they are not greater than those existing between the 

 three males now at the i\cademy." 



Brechmorhoga mendax Hag. September.
