CORRESPONDENCE. 



NOTES ON HEPIALUS. 



In Can. Ent., Vol. XXV., p. 124, Mr. Neumoegen and myself referred 

 Hepialus quadrignttatus as a synonym of H. argenteomaculatus. and 

 described the salmon-colored form as a new variety. To this Mr. Grote 

 objected (Can. Ent.. XXV., 186) and also Dr. Strecker, Proc. Acad. 

 Sci. Phila., p. 282). In view of these opinions, it seems probable that we 

 were wrong, and I correct the synonymy below. In the same paper, Dr. 

 Strecker describes as new Hepialus los. I cannot see in his description 

 anything but a form of argenteomaculatus, wanting one of the basal silver 

 spots and possessing some additional spots subapically, such as we often 

 see in quadrignttatus. I have had in my collection for some years a 

 specimen more extreme than this seems to be, for it has none of the silver 

 spots, being otherwise normally marked. I would propose for it the 

 name perdita. 



Our species of Hepialus of large size, with the apices of primaries 

 rectangular, may be arranged as follows, and the generic term Stenopis, 

 Pack, may be retained for them : —
