APPENDIX SS. 1863 



Fidonia Stalachtaria, n. sp. 



Expands finch. Shape of F. Fvmetaria G.-R., to which it is closely allied. Head 

 and body powdered with whitish and black scales. 



Upper surface wings rich orange color: primaries whitish gray along the inner half 

 of costa. A short dark-brown band extends from middle of costa to the median 

 nervure, where it is narrower than at the costa : halt-way between this and exterior 

 margin is another band, which extends from costa, where it is broadest,to inner margin. 

 This last band is in part almost continent with a broad brown border of exterior 

 margin; between the latter and this band, at and near the costa, is a pale yellowish- 

 white mark narrower than in Fim&taria; median nervure brown. Secondaries with a 

 broad brown border to exterior margin: this border incloses a row of almost confluent 

 orange spots, which commences at the anal angle and extends two-thirds in toward 

 the apex; interior to the marginal border, and parallel with it, is a brown mesial line; 

 all fringes pale yellow, alternated with brown terminations of veins. 



Under surface, primaries bright orange, except at costa and apex, where the color 

 is pale yellow, the dark lines same as above but paler, and the outer one does not reach 

 to the exterior margin, there being a narrow pale space between. Secondaries pale- 

 brownish with three irregular bands composed of more or lessclosely connected pale-yel- 

 low irregularly shaped spots: also between the innermost of these bands and the base 

 are several more irregular pale yellow marks; there are traces of silver in the spots of 

 under .side of secondaries, as in Fimetaria, though there is considerable resemblance in 

 the arrangement of all the markings. 



Two examples, August 10. at Rio Navajo, near mouth of canon of its headwaters.

 Metrocampa Tirida perlata. Packard, Proc. Post. Soc. Xat. Hist. xvi. p. 38 (1874). 



Three examples, July 27. head of Tule Valley, at Weeminnche Creek. August 11, 

 Rio Navajo, at its headwaters and at. other points. These are in no way different from 

 Eastern examples; it is found in British Columbia and in all parts of the United States 

 and Territories except in the far South. 



Some years since I obtained a large number from S. Labrador; these were all of small 

 size. The largest I ever saw were from California and Pennsylvania : when fresh caught 

 and unsullied this is a most lovely thing to behold, but in a very short time the beau- 

 tiful pale sea-green shade disappears. 



Genus EUGONIA Hub.

Eunomo.s Coloradaria. G-BOTE, Annuls Lyceum of Xatural History of Xew York. viii. t. 16. f.

 Tetraeis Coloradaria. Packard. TJ. S. Geo. Sur. Terr. Havtlen, x. p. 530, t. 12, f. 47 (1876). 



One of this fine species. July 21, at Pagosa Springs. It is easily distinguished from all 

 others of its genus by the two heavy black bands (rather than lines) of primaries. 



Genus EUASPILATES Pack. 



Euaspilates Spinatarla. 



Euaspilates Spinataria, Packabb, Sixth Report Peabody Acad. Sci. p. 45 (1874) : U. S. Geo. 

 Sur. Terr. Hayden, x. p. 204, tiyure (1*7(3). 



Two examples were taken ; both have the dark lines of primaries much heavier than 

 represented in Packard's figure.

 Genus HETEROLOCHA Led. 

 HeteroJocli a Edwardsa la . 



Heterolocha Edwardsata, Packaed, Proceedings of x\w Boston Society of Natural History, 



xi'i. p. :J83 (1871); U. S. Geo. Sur. Terr. Hayden, x, p. 478, t. 11. f. 48 (1876). 



This species was quite abundant: it was taken at the West Fork of the Rio Navajo, 



near its headwaters, at the Rio Blanco, and at the Rio de los Pinos near the crossing 

 of the upper road; it was in no particular different from California examples. 



Genus EURYMEXE Dup. 

 Eurymene ExceUa,!*.. sp. 



Expands 1£ inches. Head and thorax bright orange ocher; abdomen yellowish- 

 white. 



Upper surface wings: primaries same color as thorax, and crossed from interior 

 margin to costa by two distinct brownish-gray lines ; the first or sub-basal is edged
