Hadena ( Psendanarta) crocea Hy. Edw. 



This form only differs from the typical fiava from British Columbia by 

 the primaries above being shaded with pale, especially on the disc, and 

 being more yellowish beneath at base, contrasting with the black border. 

 These colorational characters do not seem to be constant, for in one 

 specimen from Oregon the pale shading is confined to a space about the 

 reniform, and in a still paler crocea from Colorado the contrast between 

 the yellow base and the black terminal band is not as great as usual. I 

 think crocea is a variety of flava. In both the exterior line is outwardly 

 bent over the median nervules and followed by a whitish and then a brown 

 shade. 



Hadena ( Pseudanarta) singula, n. s. 



$ . The primaries have the exterior line not so roundedly exserted 

 over the median nervules and not followed by a white or brown shade. It 

 forms a short tooth opposite the cell. The double black dash on s. t. line 

 opposite the cell is distinct and long. Beneath as in flavidens, but differ- 

 ing from this in the wider median space and the prominent flexures of the 

 anterior line inferiorly. The terminal black band on the yellow second- 

 aries above wider than in the other forms. Collected by Belfrage in 

 Texas and considered a variety of flava by Mr. Morrison. 



Perigea falsa, n. s. 



g £ . Eyes naked ; tibiae unarmed. Color and appearance of 

 Mamestra arietis or pallilis, but a little more dusky and yellowish. The 

 color is gray with a mixture of yellowish and fuscous scales. All the 

 markings and lines broken. Stigmata concolorous, with broken black 

 annuli, large, inconspicuous. Posterior line a succession of white venular 

 dots more or less evident, preceded by black dots persistent. Subterminal 

 line uneven, indicated by the difference between the fuscous shaded s. t.
