lACKABD.] ZOOLOGY ^MOTHS OF COLORADO. 549 



Family Phaljenid^. 



Baptria alhofasciata, Grote. — "Pike's Peak" (Grote). It may here be 

 said that four Baptria albovittata, Guen., from Victoria, Vancouver 

 Island, do not differ in size or coloration from eastern examples. 



LitJiostege triseriata, Pack, (Rep. Peab. Acad. Sc, 1874). — Denver City, 

 Col., June 3, 27 (T. L. Mead). — This is the first occurrence of this genus 

 in America. Another species inhabits California. 



Larentia ccesiata, S. V. {Cidariaaurata, Pack., Proc. Boston S. IS". H,, 

 XI, 51, 1867).— Vicinity of Georgetown, 8,000 or 9,000 feet elevation, 

 Colorado (T. L. Mead). The Colorado examples expand from 1.45 to 1.55 

 inches ; the markings just as in Labrador and White Mountains (New 

 Hampshire) specimens, though with perhaps more golden scales The 

 Labrador specimens are a little stunted, expanding from 1.40 to 1.45 

 inches; they agree with specimens from Iceland as to general appear- 

 ance and size, but are not quite so dark and have more golden-yellow 

 si)ecks. I have seen no specimens from this country or Labrador with 

 such clear markings as in those received from the Austrian Alps, tliougb 

 the American specimens are rubbed. In size, the Colorado individuals 

 resemble the European ones. Near Turkey Creek Junction. 



Lohophora ')nontanaia,'P-dck. (Rep. Peab. Sc, 1874). — Colorado, June 28 

 (T. L. Mead). Tliis very interesting species is closely related to L. hal- 

 terate, which occurs in Central and Poutheru Europe and Middle Lap- 

 land. It is also closely allied to L. car-pinata^ found in Central and 

 Southern Europe as well as in Eastern Siberia, the Ural Mountains and 

 Amurt 



Cidaria populaia (Linn.) — One specimen occurred in the vicinity of 

 Berthoud's Pass, Colorado, 12,000 to 13,000 feet elevation, August 16 

 (T. L. Mead). On comparing this single example with specimens from 

 Massachusetts, the White Mountains of New Hampshire, and several 

 from Victoria, Vancouver Island (G. R. Crotch, Mus. Comp. Zool.). it 

 differs in there being three well-marked teeth in the outer edge of the 

 median band ; the inner edge above the median vein is jagged instead 

 of straight as usual, while the coloration is the same. I have had no 

 European specimen forcoujparison, but it agrees with figures. It occurs, 

 however, in Labrador (Moeschler). In Europe, it occurs in the central 

 and southern portions and in the Ural and Altai Mountains and Amur. 



C. luguhrata, Moeschler (C. niiMlata^ Pack., Proc. Bost. S. N. H., 1867). 

 Mountains of Colorado, July 19, September 8 (Lieutenant Carpenter); 

 Denver City, Col., June 1, (T. L. Mead); California (H. Edwards); Vic- 

 toiia, Vancouver Island (Crotch., M^C, 2). Though my Labrador speci- 

 men differs somewhat from Moeschler's description and figure, yet I am 

 inclined to unite it with C lugubrata. I have before me a specimen from 

 Mount Marcy, New York (August), and Mount Washington, New Hamp- 

 shire (Sanborn), and numerous specimens from Calilorniaand Vanc;)uver 

 Island. Theextn-mesarepresentedby the Labrador and Vancouver I;sland 

 examples. The Pacific coast forms are larger, blacker, the fore- wings more 

 elongated toward the a])ex than the eastern specimens, much as observed 

 in Macaria dispnncta (Walk.), in which the Labrador indivi<luals are 

 stunted, while the west-coast (Vancouver Island) specimens are larger. 

 They are i)aler, however, than the Labrador and New England individu- 

 als. The (Colorado 0. lugubrata scarcely differs from the Californian and 

 Vancouver Island ones. My Labrador individual (well preserved) has 

 already been described. The Adirondack (Mount Marcy) one is very 

 similar, but differs in being of a i>eculiar reddish-brown tint,, especially 

 along the costa and veins. The outer line between the costa and median
