the median vein, -which is white, as well as its second and third 

 branches; the apical costal branches are also whitish. Posterior 

 wings and under surface white, immaculate.

The description of this species is necessarily short, on account of 

 the uniform tint, and entire lack of ornamentation. The remarkable 

 color of the anterior wings, as well as the absence of all black mark- 

 ings, will at once separate it from Helioplula pliragmaiidicola Guen., 

 to which it is allied. 



Caradrina tarda Guen. 



We have identified in the collection of Prof. Julius E. Meyer, of 

 Brooklyn, N. Y., this species, which has hitherto remained unknown J 

 it is a very well marked insect, and can not possibly be mistaken; 

 however, we give the following short description, as none has yet been 

 published in English. 



Eyes naked. Thorax smooth, and closely haired. Abdomen short 

 and untufted. Second joint of palpi black, the third white and con- 

 trasting. Ground color of the anterior wings dull gray-brown, as in 

 Pseudocodes vecors Guenee ; the ordinary spots apparently obsolete; 

 the median lines distinct, simple and black, the interior line well- 

 lobed, the exterior even and continued; the median shade subpar- 

 allel with the exterior line, thick, black, and strongly curved in the 

 middle (in this respect the species differs from M. Guenee's descrip- 

 tion, but it is a character liable to vary) ; the subterminal line yellow 

 and conspicuous, preceded by dark shades; fringe concolorous. 

 Posterior wings uniform fuscous gray. Beneath the wings are dark 

 gray, and have the usual common median line, the posterior wings 

 are slightly lighter, and have the discal dots. 



Hab. West Virginia. 



Caradrina derosa nov. sp. 



Expanse, 33 mm. Length of body, 14 mm. 



Eyes naked. Form stout. Thorax not tufted, its clothing short, 

 but coarse and mingled with scales. Palpi short. Abdomen smooth, 

 stout, not tufted. Tibise unarmed. Collar with an interrupted black 

 line, otherwise concolorous with the thorax and anterior wings. 

 The latter are gray, the color of Agrotis messoria Harris, the mark- 

 ings are black and indistinct ; the half-line present; the interior line 

 geminate, lobate and interrupted ; the median shade present, running 

 between the nearly obsolete ordinary spots, where it is thickened, 

 forming a black spot ; a series of light and dark dots on the costa ;
