recognized by its rich, golden-yellow wings, the checkered costa of 

 the anterior pair, and the broad, dusky margin of both wings, while the 

 hind-wings beneath are beautifully marbled. 



Macaria Califormata,Fack. (Fig. 7). — This common Californian species 

 has also been collected by Mr. Eidings in Colorado, and by Prof. F. N. 

 Snow in Kansas ; it is also frequently taken in Texas. 



M. dispuncta. Pack. {Tephrosiadispuncta, Walk.; Macaria sexmaeulata, 

 Pack., Proc. B. S. K H., 44, 1867). One individual was collected in Col- 

 orado by Mr. Mead. It is rather larger than specimens from Victoria, 

 Vancouver Island, collected by Mr. G. E. Crotch, and is much darker, 

 being much as in eastern specimens. The lines on the fore-wings are 

 rather broad, and the dark, broken spot in the middle of the wing, near 

 the outer edge, is obscure and united to form a faint patch. The hind- 

 wings are without any submarginal shade, as in some eastern examples. 



I am disposed to regard my 3L sex-maculata from Caribou Island, 

 Labrador, Straits of Belle Isle, as a variety of this species. It is very 

 closely allied to it. It is rather smaller than usual ; the fore- wings 

 tinted with an obscure olive-gray, while the hind-wings are uniformly 

 ochreous-brown, not mottled with whitish as usual ; the costal Ri)ots on 

 the fore-wings are rather large. It chiefly differs, however, in having a 

 large brown spot in the course of the median line next to the usual 

 large brown spot, the two forming twin-spots. Beneath, it does not 

 differ from other examples from Maine. The specimens from Norway, 

 Me., closely resemble the Labrador form, in haviugthe inner spot much 

 enlarged, though otherwise of the typical mode of coloration. 



Two males and two females from Vancouver Island, collected for the 

 Museum of Comparative Zoology by Mr. G. E. Crotch, are rather larger 

 than the average of our eastern specimens, with longer wings ; but they 

 do not materially differ. One specimen scarcely differs from an indi- 

 vidual from New York. They are, however, rather whiter than usual, 

 with the submarginal band nearly jjbsolete. All have the inner division 

 of the median dark patch on the fore-wing broad, thus exactly resem- 

 bling the New York example, though not so well marked as in the 

 Labrador specimens. Beneath, the common, broad, submarginal baud 

 is ochreous and nearly obsolete. It is interesting to notice how the 

 species varies away from its apparent geographical center, the North- 

 eastern States. In Labrador it grows much smaller, is stunted and 

 darker ; while at Vancouver Island, about one hundred and fifty miles 

 farther south in latitude, it grows rather larger than in the Eastern 

 States, with the wings decidedly more elongated and paler. This spe- 

 cies is very common in the New England States, Norway, Me. (S. I. 

 Smith, Mus. Comp. Zool.), Cambridge, Mass. (Mus. Comp. Zool., A. 

 Agassiz), and occurs at London, Canada (W. k-aunders,Mus. Comp. Zool.) 



Macaria enotata, Gueu. — This species, though only recorded heretofore 

 from Brazil, Surinam, and Cayenne, occurs in the Northeastern States 

 and in Kansas, whence I have received it from the museum of the De- 

 partment of Agriculture at Washington, through Prof. T. Glover. It 

 will undoubtedly occur in Colorado. 



Eumacaria brunnearia, Pack. — Head of Plum Creek, June 29 (Lieuten- 

 ant Carpenter). The larger of ten eastern and Texan specimens measures 

 0.48 inch on the fore-wing, while the single Colorado one is 0.53 inch. 



Corycia vestaliata, Guen. — Colorado (Eidings) ; near the South Platte, 

 June 28 (Lieut. W. L. Cari)enter). 



Acidalia Californiata, Pack. — Mountainsof Colorado, July 22to August 

 12-20 (Lieutenant Carpenter) ; banks of Blue Eiver, Middle Park, ele- 

 vation about 9,000 to 10,000 feet (Mead) ; Colorado (Mr. Ridings). Ilav-
