Vol. XXX] ENTOMOI.OOIC.U, NEWS 185 



The original account of this species states that the type local- 

 ity is Hamburg, New York, and that the type is in the U. S. 

 National Museum, No. 3440. There is no specimen in the 

 Museum from Hamburg, N. Y., and that bearing No. 3440 is 

 from Washington, D. C, June 23, 1890. If this is really part 

 of the original material, it is only a paratype ; the whereabouts 

 of the holotype is unknown to the writer.
