The present species is probably the most variable, as it is the 

 most widely distributed, form in the genus and the above synon- 

 ymy illustrates the difficulty previous authors have encountered 

 in endeavoring to determine material belonging to it. The 

 present authors have given more time and consideration to it 

 than to any other member of the genus, and after the most critical 

 examination of the specimens in hand and a careful testing of the 

 evidence on which the numerous synonyms were erected, we are 

 thoroughly convinced that concinnum is a very variable form, 

 showing decided geographic size variation, probable environ- 

 mental adaptations in ovipositor characters in the female and
