are larger, with the yellow on the hind-wings deep orange, being much 

 higher colored than in the European. The body of the European is 

 nearly as large, but the wings are shorter and snial'er. The European 

 example also differs in the smaller silver spot, in the line across the 

 wing just beyond the silver spot being more curved just below the costa, 

 and in the smaller veniform spot ; but in both of the former characters 

 there is a slight amount of variation in the Colorado specimens. 



One European examjjle, $ , length of body, 0.63 inch; length of fore- 

 wing, 0.53 inch. 



Ten Colorado examples, S , length of body, 0.65 inch; length of fore- 

 wing, 0.60 to 0.63 inch. 



In Europe, this species has been found in the Alps, Scandinavia, and 

 Lapland. 



Tarache candefacta, Hiibner. — Head of Plum Creek, June 29 (Lieu- 

 tenant Carpenter). 



Heliothis armigera^ Hiibner. — Foot-hills of Long's Peak, May (Lieu- 

 tenant Carpenter). 



Hydrcecia lorea, Guen. — Head of Plum Creek, June 29 (Lieutenant 

 Carpenter). 



Hamestra picta, Harris. — A larva occurred in the alcoholic coUectiou 

 (Lieutenant Carpenter). 



Scoliopteryx Ubairix (Linn.) — This was collected by Lieutenant Car- 

 penter in the Rocky Mountains of Wyoming in 1872. It has also been 

 found by Kennicott on the Yukon Eiv^er (Grote). 



Agrotis Islandica, Staudinger (Stettin Ent. Zeitung, 232, 1857), (Fig. 

 10). — 8 S ; 2 9 . Tbis tine species is allied in its form and structure, in 

 the strongly-ciliated antenuse, the tufts on the prothorax, andin the form 

 of the wings to A. suhgothica, Haworth, and less stronglj^ to A. jaculi/era, 

 Guen. Male antennae stoutly ciliated to near the end. Palpi much as 

 in A. stibgothica; third joint rather stout, lilac-gray, like the bead, black- 

 ish along the upper side and on the end. Prothoracic scales light tawny- 

 yellowish at base, concolorous with the light tawny costa of fore- 

 wings; beyond, a blackish curved line; outer edge of the scales lilac- 

 gray, like the rest of the thorax. Fore- wings pale-tawny, sometiuies 

 with a reddish or whitish-gray tinge. Two or three faint, small, costal, 

 dark, transverse, oblique streaks within the middle of the costa. Sub- 

 costal and median veins from renitorm spot to base of wing white, 

 dilating into a very narrow triangular streak at biise of discal space. 

 Discal dot and reniform spot large, white. Dot oblique oval, widening 

 on median vein, scarcely separated at other end from the pale costa. A 

 black space between the two spots about as long astbedot itvself (the s[)ac6 

 varying, however). Reniform si)ot large, white, with two median, curved, 

 dark lines, a dark shade beyond, equal to the reniform spot in width. 

 Beyond is a clear reddish-brown space crossing the wing, interrupted 

 by tbe black venules, and bordered internally by dark intervenular scal- 

 lops (sometimes obsolete). Tbe clear space has in the outer half a series 

 ot black intervenular slashes, terminating in a fine, irregular, scalloped, 

 whitish line, the line dislocated and situated much nearer the outer e(\ge, 

 below tl)e middle of the wing. Just below the median vein, on inner 

 half of wing, a black stripe, interrupted by a transverse, acutely-curved, 

 reddish-brown line extending from tbe median to tbe subniedian vein, 

 and sometimes extending beyond the edge of wing; beyond this tbe 

 outer half of tbe black streak is broader, lanceolate-oval, and terminates 

 on the submedian fold at a poi»nt opposite the outer end of diskal dot. 

 Fringe concolorous with the clear portion of the wing. llind-wings 

 wihtish near the base, becoming gradually smoky on tbe outer third.
