CHAMBERS ON TINEINA OF COLORADO. 129 



yellowish-white, four small black spots on each segment, and six lon- 

 gitudinal purplish lines. 



Another was taken at the highest altitude at which any Lepidop- 

 terous larva, was observed ; that is, at an altitude of nearly 12,000 feet. 

 The timber-line on Mount Elbert, where this larva was found, is given 

 by I lay den (Report, 1873) as 11,871, but the dwarfed and stunted wil- 

 lows usually extend along the courses of the little rivulets some feet 

 higher than timber-line as popularly understood (that is, the limit of 

 growth of trees — pines and aspens). Feeding on the leaves of these 

 dwarfed willows, and sewing them together in little bundles, I found this 

 larva, but, unfortunately, did not succeed in rearing it (one pupa still 

 living may produce an imago next spring). It is at first green, but as 

 the larva gets older it becomes dark olive-green, with the black tuber- 

 cular spots placed 4-2. Head and upper surface of uext segment black. 

 It attains about one-half inch in length. 



Another larva sews together leaves of aspens, and is found up to the 

 extreme limit of the growth of that tree. The head and thorax are dark 

 brown, the other segments purplish-brown, with black tubercular spots 

 placed as in the last species (supra), and with six longitudinal white 

 lines extending over the other segments ; length over two-thirds of an 

 inch. Another, or probably a younger stage of the same larva, has the 

 head and next segment pale stramineous and the other segments paler. 



Another, found also sewmg together aspen-leaves, but possibly the 

 larva of a Tortrix, is greenish- white, with a spot on each side of each seg- 

 ment piceous; length, three-fourths of an inch. 



fficophora borcasella Cham. (Can. Ent., vol. v, p. 189). — From near Cov- 

 ington, Ky., altitude about 1,200 feet; London, Ontario, Canada; and 

 Belleview Mountain, near Idaho Springs, Colorado, altitude about 10,000 

 feet. 



CE. i-maeulella Cham. (Cin. Quar. Jour. Sci., vol. ii, p. 292). — From 

 Spanish Bar. 



GlypMpteryx montisella Cham. (Cin. Quar. Jour. Sci., vol. ii, p. 292). — A 

 handsome and very variable species, taken in large numbers in July and 

 August at Spanish Bar, feeding on flowers of Helianthits and Heliopsis ; 

 altitude, 7,800 feet. The food-plant of the larva is unknown. A single 

 specimen which I believe to belong to this species was observed but not 

 captured on Mount Elbert, at an altitude of about 10,000 feet. 



Lithariapteryx abroniceella Cham. (Can. Ent., vol. viii). — Among all the 

 little gems (Litharia) of the entomological world, a large proportion of 

 which belong to the Tineina, I know of none that surpass this species 

 in the beauty and elegance of its adornment. As a mere object of 

 beauty for the low powers of the microscope (say 5 to 10 diameters), it is 

 almost unrivaled. It is also interesting structurally, for its relation to 

 four other genera of GlypMpterygidm, being about equally related 

 to GlypMpteryx, JEJchmia, Perittia, aud Tinagma. The imago is fond of
