CHAMBERS ON TINEINA OF COLORADO. 149 



same everywhere, or, if it varies, varies in the same way everywhere 

 Gelechia, usually so numerous, both iu species and individuals — more so 

 than any other genus of the family— is but poorly represented in the 

 mountains, more numerous in the foot-hills and plains than in the 

 mountains, and seems to be more numerous in southern latitudes, as well 

 as iu lower altitudes. The species are usually of plain grayish or brown- 

 ish colors, and present no contrast with their congeners from the East, 

 either in ornament or structure. Glyphipterygidce are represented by (t. 

 montisella Cham, and Lithariapteryx abroniwella Cham., the latter per- 

 haps more brilliantly ornamented than any other species of the family, 

 but neither showing any greater extent of peripheral parts. Holcocera 

 (Blastobasls) gigantella Cham., however, on the other hand, has cer- 

 tainly a greater expanse of wings — 15$ lines — than any other species of 

 the genus, or perhaps I might say greater than any other species of the 

 Tineina; but the wings are rather narrow for their length, and unlike 

 all other species of the genus known to me (instead of having a deeper 

 or more brilliant or intense color) it is white. Indeed, it seems to me that 

 if the Tineina of Colorado have any characteristic colorational peculiar- 

 ity, it is that there is perhaps a larger proportion of uncolored species. 

 . 1 rgyresth ia and Gracilaria are more numerously represented in Colorado, 

 both by species and individuals, than any other genus, except Gelechia, 

 and their species are decidedly less brilliant, and are plainer than the 

 species of the Mississippi Valley, and where the species are the same 

 they present no peculiarity of either form or color. Coleophora is well 

 represented by characteristic species ; Laverna by a few plain species ; 

 Batrachedra by a species which I believe to be the European prwangusta, 

 and by another new species (?) which certainly has a decidedly greater 

 wing-expanse than any of the known species, besides being more deeply 

 colored, not more brilliantly. Eriphia concolorella Cham., found as yet 

 only in Colorado and Texas, is the same in both, so far as we can judge 

 from the scanty material. Tischeria is represented by two species found 

 in the Eastern States. Lithocollctis is less numerous, both iu species 

 and individuals, than in the States, where, next to Gelechia, it is perhaps 

 the most abundant both iu species and individuals. Three out of seven 

 species are identical with those found in the East, and perhaps the 

 fourth and fifth will also be found there, and the sixth is found in Texas, 

 while the seventh, a variety of robiniella Clem., is smaller and of 

 duller colors. The others show no departure from the common forms. 

 The two species of Phyllocnistis have already been found in the East ; 

 they present no variation. P. populiella Cham., from an altitude of 

 over 11,000 feet in the Snowy Eange, is indistinguishable from the 

 same species in the foot-hills at 0,000 feet, or from Kentucky at 500 

 feet. The single species of Lyonetia, more abundant in individuals than 

 any other species, is unknown in the East as yet; and while not sup- 

 porting the theory as to color, is, on the other hand, certainly larger 

 than the other species of the genus. Bucculatrix has two species, both
