SCOTOGRAMMA ALTA Sp. nOV. 



Superficially differs from oregonica in the almost complete lack of rufous 

 on the primaries, being grey with a slight luteous tinge. The maculation is much 

 more intensified. On the under side of the secondaries the discal spot is nearly 

 n clean round dot instead of a triangular mark. The differences in color and 

 brighter maculation are conspicuous when a series of both species are examined. 



Type localities and number and sexes of types: Holotype $ , 12 June 1921 ; 

 Allotype 9, 10 June 1921; both Nordegg, Alta., (J. McDunnough) ; 34 S, I 9, 

 Paratypes, Nordegg and Pocahontas, Alta., (J. McDunnough and K. Bowman). 



ScOTOGRAMMA SUBALBIDA sp. IIOV. 



Not dissimilar to typical oregonica, smaller, the under side conspicuously 

 paler, almost whitish. 



The male genitalia lack the ordinary spine and bulb in the penis, but are 

 armed with a plate of serrate teeth instead. 



Type locality: Whitehorse, Y. T., (Alaska). 



Number and sexes of types: Holotype $ , "6.4./16", unique. 



ScOTOGRAMMA CASTRAE form ULTRA nOV. 



The types { $ $ ) of castrae correspond to the albifusa form of trifoHi 

 in the possession of contrasting maculation and a pale area from the costa thru 

 the orbicular to the t. p. line. 



The present form is much less contrasty, lacking the median pale area, 

 presenting a uniform appearance, its habitus at first suggesting a distinct species. 



Type locality: Jemez Springs, N. Mex. 



Number and sexes of types: Holotype $, 24-31 July; Allotype 9, 8-15 

 July; 1 $ Paratype, 24-31 July; 1 9 Paratype, 8-15 July.

Four specimens received from Fort Lauderdale, Fla., through 

 the kindness of Mr. D. M. Bates, agree with Hampson's characteriza- 

 tion of the species and match the series in the National Museum. 

 The name should be placed on North American lists.
