INSECUTOR INSCITI^ MENSTRUUS 69 



The generally uniformly brown mesonotum separates it easily 

 in my experience. 



Group punctor 



Edwards lists two species in Europe of this group, to both 

 of which he cites American names. Aedes punctor, var. 

 meigenanus Dyar represents our punctor, and A. sticticus Meig. 

 represents the hirsuteron subgroup. To the latter A. aldrichi 

 is cited as a synonym with a query. Unfortunately I have not 

 seen any specimens of sticticus, and for this reason stated that 

 the group was unrepresented in Europe (Ins. Ins. Mens., ix, 

 09, 1921). This statement is to be corrected; but I do not 

 think that Mr. Edwards has established the identity of sticticus 

 with any American species. It is doubtless a close representa- 

 tive, and appears to have the same habits. Eckstein is quoted 

 as stating that the larvae occur in flooded meadows, together 

 with vexans and dorsalis, and to pass through several genera- 

 tions during a year. With us, dorsalis does not occur in flood- 

 water with the other species, but the habits of that are not here 

 under discussion. The appearance of having several genera- 

 tions may be due to successive hatchings in different floods, an 

 appearance often noted with us and commented on by me 

 (Ins. Ins. Mens., v, 113, 1917). If sticticus is to replace any 

 American name, it will be hirsuteron or aestivalis, and not 

 aldrichi, which is a smaller form having the mesonotal stripe 

 divided. 



In regard to punctor, we have a number of very close species 

 in America, from which the European form seems specifically 

 detached. I am therefore not inclined to depart from my 

 position previously discussed (Ins. Ins. Mens., ix, 72, 1921), 

 and consider that the European form should be called Aedes 

 meigenanus, and that punctor is its American representative. 



Group impiger (decticus) 



Under Aedes communis De Geer, Edwards gives lasarensis 



F. & Y. as an absolute synonym and tahoensis Dyar and pionips 



Dyar as synonyms with a query. In regard to the former, I 



have examined mounts of the hypopygium of European speci-
