Mr. Morrison's type is in the Tepper collection. Mr. (1 rote's types I 

 have not seen. They may be in the British Museum; but if so I over- 

 looked them. The species has not been critically studied, and the true 

 relation of the forms is yet in doubt. The American form may yet 

 prove distinct, though a very close ally to the European insect. I am 

 not nearly so ready to believe in the identity of European and Ameri- 

 can species as I once was.

Iii this genus and in the following, from which the present has been 

 separated, I have few original notes. Dr. Riley has been accumulating 

 material for several years past for a critical and revisional monograph 

 of the species, and what little I have done is in his hands. Dr. Biley 

 has made comparisons in the European museums, and I did not, there- 

 fore, look over the species except as they came accidentally under my 

 notice. So, too, I have given the location of the types only where they 

 are in American collections of whicli 1 had notes, or where I accident- 

 ally noted the fact. The bibliography, however, is as nearly complete 

 as iu most other genera.
