Plot". J. B. Siuitli. But Professor Smith iiuiintuins the distinctness 

 of these species," though he admits cerviaiHi to l)e the northwestern 

 representative of the enstGrn ^fi/iitu/ia, and I according"ly so refer it. 



HADENA LONGULA Grote. 



One specimen August 11, nuicli worn and faded; also one lioni Mr. 

 Cockle's collection September 18, 11>(»1. 



HADENA REMISSA Hubner.

HADENA DUBITANS Walker, var. COGITATA Smith. 



Four hundred and thirtj-two specimens. June 21, July 14, 2-t, 27, 

 29 (Bear Lake), 30, August 5, (5, 7, 12, 16, 17. iVIany of the specimens 

 are light, nearly like Smith's type of cogitata, but they run darker 

 also, the darkest fully matching the ordinary dahltaihs of the East. 

 This is not a racial distinction, as eastern specimens are vsometimes 

 light. The name cogltida can b(» used to designate the variation.

Nine specimens, July 25, 27, August 1, 6. 12, 17.

 6, 7, 11, 12, 13, 15, 16. Although this species and ^/(//^/^frt/j.s' were very 

 conmion, it was impossible to obtain the life history of either, though 

 efforts were made to do so. The captive females refused to deposit 

 eggs.
