NO. 1376. LEPIDOPTERA OF THE KOOTENAI DISTRICT— DYAlL 825 

 NOCTUA BAJA Linnaeus. 



Six hundred and fourteen specimens, .July 27, 8(1, Au<;ust 2, ."). ♦>, 

 7, 13, i<), 17, 18. This is unquestionabh' the European species. It 

 was long so recognized till in 180G Mr. P. T. C. Snellen named the 

 American form siii!th!l^ on the supposition that it had spinose fore 

 tibia' while the European one had not. But an examination of Euro- 

 pean specimens shows them to have several distinct spines towaid the 

 tip of the member, well hidden in the vestiture. I therefore restore 

 the old name. The specimens ])efore me vary from red brown to gray. 



NOCTUA PLEBEIA Smith. 



Twenty-eight specimens, July 19, 27, August 1, 0, 7, 11, 10. The 

 form is not ver}'^ variable, and seems to be a distinct species. 



NOCTUA ROSARIA Grote. 



Ninety-two specimens, May 29, June 7. 11, 23, 30, July 19, 21. 26, 

 27, 29, 31 (bred), August 1 (bred), 4 (bred), 7, 11, 13. I have attempted 

 to arrange these specimens in two series corresponding to romrld and 

 e^drndis, but they insensibly intergrade. I can not see that Professor 

 Smith demonstrates any difference between the male genitalia" beyond 

 what i.' accounted for in difference of drawing and natural variation. 

 On examining several specimens 1 see enough variation to account for 

 the *• nuich narrower harpes" of esurlalts which Professor Smith notes.
