THE CANADIAN ENTOMOLOGIST. 133 



so I had it until Mr. Dod sent me a series for comparison. Compared 

 with the Colorado species this is smaller, darker, less powdery in the 

 female, with rays on the veins even less marked. The oblique white line 

 on the patagia is seen in some examples of Rid'mgsiatia, and does not 

 seem to be distinctive. With the males only at hand I should hardly 

 venture to separate this species, though even in this sex there are minor 

 differences that seem constant. In the females the distinction is well 

 marked, that ol niaimes differing little from the male, while in Ridingsiana 

 all the examples of that sex are paler, more ashen, dusty gray, with less 

 contrasting maculation. 



Hadetia (Xylophasia) sora, n. sp. — Ground colour a deep, some- 

 what rusty red brown. Head may be a little darker. Thorax may be 

 blackish on disk of patagite, the central divided crest lighter. Primaries 

 with the maculation all present, but not contrasting. The basal space is a 

 little the lightest part of the wing ; next comes the s. t. space from the 

 middle to the inner margin, and then the apex ; but the difference is not 

 striking, and is more a mottling with yellowish or gray. The basal line is 

 geminate, of the brown ground colour. T. a. line geminate ; the inner 

 line obscure, the outer narrow, blackish, the included space a little paler ; 

 as a whole the line is outwardly oblique, a little outcurved in the inter- 

 spaces, a longer outcurve from the internal vein to the margin. T. p. line 

 lunate or even crenulate, geminate, the outer line more even ; as a whole 

 with a moderate outcurve over cell and an even course below. S. t. line 

 pale, irregular, forming a small W on veins 3 and 4 ; emphasized by a 

 narrow brown preceding shade and by the dark smoky terminal space. 

 There is a series of blackish terminal lunules, beyond which the fringes 

 are cut with luteous. In the basal space there is a slender longitudinal 

 black line, which runs beneath the sub-median vein, and does not quite 

 reach the t. a. line. Claviform small, concolorous, outlined by black 

 scales, pointed, giving rise from the tip to a somewhat diffuse black line, 

 which extends across the cell to the t. p. line. Orbicular narrow, oval, 

 oblique, not well defined, rmged with yellowish, with or without a j^ale 

 centre. Reniform large, a little constricted, incompletely outlined, the 

 centre a little smoky. Secondaries smoky brown, a little glossy, the 

 fringe more yellowish. Beneath, smoky over a reddish base; both wings 

 with a more or less obvious discal spot and a smoky outer shade line or 

 band.
