 any parallel but distinct species which may occur in North America, 

 but I have always been of the belief that the North American form

 than a variety of the typical form, although I have never had the 

 opportunity to compare specimens from both continents to make cer-

My specimen of this bat-infesting bug is deposited in the collection 

 of the University of Nebraska at Lincoln, and I do not have the exact 

 data here at hand, but I submit this note for what it may be worth. —
