There is in Europe another species, A. caspius Pall., closely 

 allied to dorsalis, but unrepresented in America. Our own 

 species allied to dorsalis, campestris D. & K., differs markedly 

 in the genitalia. There seems to be no close representative of 

 our canadensis Theo. in Europe, either. It seems rather curious 

 that our curriei should be identical when all the others differ, but 

 all stages have been examined carefully without any differences 

 becoming apparent. It is to be noted, however, that the habits 

 of the European dorsalis are not the same as those of our 

 curriei, since the former is said by Eckstein to breed in flood- 

 water with sticticus and vexans, which curriei never does.

The relationship of these forms is obvious and interesting. 

 1 can make but one species common to both Europe and Amer- 

 ica, by which another of our familiar names disappears, as 

 follows :
