CHAMBERS ON TINEINA OF COLORADO. 123 



GeJecMaserratixyalpella u. sp. — From the peculiar structure of tbe palpi, 

 this species will probably be excluded from the true GeJechia ; they re- 

 semble those of G. gall (vsolid agin is ^i\ey, exce])t that the scales along, 

 the lower edge or surface are arranged like the teeth of a saw, more 

 especially those of the second joint, as in galkvsolidaginis, both the 

 second and third joints are laterally compressed, the third joint having 

 a blade-like form. Iq this species, the tip of the third joint projects as a 

 minute point beyond the scales. Hind wings sharply emargioate be- 

 neath the tip, and again a little so behind the anal angle (that is, there 

 is a slight projection, or tooth, between the tip and the anal angle, 

 and another very little one at the anal angle). Both pairs of wings 

 rather narrow. Palpi, head, thorax, and antennae gray (under a lens 

 of higher power they appear pale-gray, dusted with brown), with one 

 or two faintly-indicated pale gray annuli on the palpi, and the antennte 

 are alternately annulate with pale gray and brown. Fore wings pale 

 orange-yellow, the base and the dorsal margin to and around the apex 

 gray ; cilia of the costal margin and the extreme costal margin to the 

 base also gray; base of the cilia dusted with brown, and the orange- 

 yellow of the apical part of the wings is also sparsely dusted with brown. 

 At the base of the wing, the gray portion is externally margined with 

 brown, and the gray of the hind margin sends three small projections, 

 or teeth, into the yellow. One of these projections is beneath the fold 

 before the middle of the wing-length ; the others are above the fold, one 

 of them about the middle of the wing-length, and the other a little far- 

 ther back. Each of these projections is tipped with brown scales, and 

 immediately behind the last one the usual costal and dorsal spots, the 

 dorsal being the largest, are indicated by a paler gray than that of the 

 surrounding i)ortion of the wing. In the cilia, at the apex of the wing, 

 is a small brown spot, and there are one or two others before it in the 

 costal cilia. Hind wings pale leaden-gray, with pale stramineous cilia. 

 Legs and abdomen gray, the tarsi annulate with white. Lower surface 

 of abdomen pale-gray ; anal tuft white. Expanse of wings, 7i lines. 

 Edgerton, in July. 



G. iiedmontella n. sp. — Resembles the preceding species somewhat 

 structurally and slightly in the pattern of ornamentation. Palpi but 

 little compressed laterally' ; third joint not blade-like, but with the point 

 ])rojecting, as in the preceding species ; second joint serrated, but less 

 distinctly so than in serratijyaljiella. Both pair of wings rather narrow, 

 the hind pair sharply emarginate beneath the apex, but the margin not 

 toothed. Palpi dark reddish-brown, marked with white, especially 

 along the upper and inner surface of the second joint, and forming an 

 indistinct annulus on the third joint. Head, upper surface of thorax, and 

 the antenna? rich brown. Fore wings red-brown or maroon color, 

 sparsely dusted with dark-brown on the disk, but densely so along the 

 margins, especially in the apical part of the wing, where brown is the 

 ])revailing hue and is dusted with white : cilia of the hind margin of a
