Ellema pineuni nov. sp. Plate 8, figs. 12, 6 , 1-^, ? • 



Male. — Head and collar, umber ; palpi brown ; thorax nmber at the 

 sides, and brownish-cinereous on the middle. Abdomen immaculate, 

 brownish-cinereous. Legs brown, with white scales on the femora and 

 at the joints. Anterior wings as long as the body, umber colored, 

 dusted with gi-ajish at the base, along the terminal margin and on the 

 principal nerrures and their branches ; within the cell is a subquad- 

 rangular blackish-brown spot; an umber-brown shade is placed over 

 the base of the nervules, filling the lower half of the post-apical inter- 

 space * half way to the hinder margin, entirely filling the disco-central 

 interspace within one-tliird of the margin, the middle portion of the 

 medio-superior, the base of the central and posterior interspaces ; the 

 outer margin of this shade is doubly curved, convex toward the 

 hinder margin, becoming concave from the medio-superior nervule ; the 

 iimer margin of the wing beneath the submedian nervure, is brownish 

 from the base to its middle ; the tips of the nervules are touched with 

 umber-brown. Cilia umber-brown, spotted with white on the inter- 

 spaces. Posterior wings above and beneath, ochreous-gray, lighter at 

 the base. Expanse of wings 1.75 of an inch; length of body .80 of 

 an inch. 



Female. — Head and thorax umber-brown, the latter grayish at the 

 sides and in the middle, with a short white line on the upper edge 

 of the wing-covers. Anterior wings broader than in the male, and 

 longer than the body ; color umber-brown, with a darker brown costo- 

 basal spot, another on the internal margin near the base, which is 

 continued in a dark shade along the internal margin ; a similar colored 

 spot occupies most of the apical interspace, and there are two within 

 the post-apical ; within the cell, a subquadrangular blackish-brown 

 spot ; of the umber-brown shade which in the male rests on the base 

 of the nervules, scarcely more than its hinder margin is visible, and 

 that indistinctly ; middle of the wing at the base dusted with grayish 

 scales, and the nervules are also more or less dusted with grayish, 

 especially the branches of the subcostal vein. Posterior wings above,

 are designated in this description are those used by Dr. Clemens in his Synopsis of
