CHAMBERS ON TINEINA OF COLORADA. 141 



visible.) Apex of the fore wings sparsely dusted with ocherous, and 

 there is a row of minute ocherous specks forming a hinder marginal line 

 about the middle of the cilia. Scales rather coarse. Expanse of wings, 

 4J lines. Near Edgerton ; altitude about 6,500 feet. 



When the three ocherous spots are not visible on the fore wings, the 

 insect is scarcely distinguishable from the species described below as 

 Bucculatrix albella except by the neuration and by the presence of the 

 labial palpi. 



Bucculatrix albella n. sp. i— Snowy white ; apex of fore wings and dor- 

 sal cilia very sparsely dusted witb brownish scales. Expanse of wings, 

 4A lines. Very near B. niveella Chainb. from Texas, and possibly only a 

 variety of that species. Also resembles B. immaculatella, Cham, from 

 Texas, but is smaller, and immaculatella has no dusting on the wings. 

 Altitude, 6,000 feet; Edgerton. 



A similar species (perhaps the same denuded) was taken among wild 

 sage (Artemisia), on which it probably feeds, at Twin Lakes, altitude 

 9,500 feet. 



Nepticula. — Both species and individuals of this genus appear to be 

 rare in Colorado. In two years, I have not met wit h a specimen of it. 

 Mines of three species have, however, been observed. One speci- 

 men of a mine of a (new ?) species in an aspen-leaf was met with at an 

 altitude of over 10,000 feet ; another of another species, in a leaf of Alnus, 

 altitude 8,000 feet ; and two mines of another species in leaves of cotton- 

 wood, altitude 6,000 feet. 



Of the seve nty-nine species hereinbefore referred to (including those 

 known only by mines, but not iucluding the Gelecliia larvae, which I 

 did not succeed in rearing), one (Batrachedra prwangusta) (if it is that 

 species), though well known in Europe, is not known in this country 

 except in Colorado; five (Pronuba yuccasella, Plutella cruciferarum, Gele- 

 chia roseosuffusella, G. cequipulsella, and Bedellia somnulentella) are 

 almost universally distributed in the United States ; seven (Anesychia 

 mirusella, Harpalyce tortricella, Gelecliia concinnisella, Colcophora argyres- 

 tialbella, C. bistrigella, Eriphia concolorella, and Lithocolletis quercitorum) 

 have been found only in Colorado and Texas; seven (Gelecliia gallcesoM- 

 daginiS) Lamna griseella, Ornix pennivorella, Lithocolletis cincinnatiella, 

 L. hamadryadella, Pkyllocnistis populiella,2LXi{\. P. ampelopsiella) have only 

 been found in Colorado and in latitude .35° to 40° in the Mississippi 

 Valley ; and four ((Ecophora boreasella, Argyresihia gcedartellaf, A. an- 

 duegiella f, and Lithocolletis salicifoliella) in Canada, as far south as 

 Kentucky, and in Colorado. 



The other fifty-five species have not as yet been found outside of Col- 

 orado. Of course, it is not meaut that any or all of these species may 

 not hereafter be fouud iu other localities. The seven species common 

 to Colorado and Texas alone have all been found only south of the 

 divide between the waters of the Platte and the Arkansas. One of
