 Eresia Tharos, Drury sp, 



Hab. — (Western) — Rocky Mountains, Colorado Territory, (Coll. 

 Tryon Reakirt.) 



A single male specimen, does not differ from well marked eastern 

 examples. 



Eresia Campestris, Bohr sp. 



Mclitaia Campestris, Brhr Proc. Calif. Acad. Nat. Sciences, p. 86. (1S63.) 

 Hab. — California ; Colorado Territory, (Coll. Tryon Reakirt.) 

 A single example is undistinguishable from those of California. 



Eresia pallida. Edwards sp. 



Melitaea pallida, Edwards, Proc. Ent. Soc. II, p. 505. (1S64.) 

 Hab. — "Texas; Kansas," Edwards. 



Rocky Mountains, Colorado Terr., (Coll. Tryon Reakirt.) 

 A series of mutilated specimens, I have referred with much doubt 

 to this species. They certainly do not correspond with any of Dr. 

 Behr's species, although very near to Campestris. The median yellow 

 band, differs, particularly upon the fore wings, from all the allied 

 forms, in being semi-translucent. 



Eresia Mylitta. Edwards sp. 



Mclitaa Mylitta, Edwards, Proc. Acad. Nat. Sciences, p. 11)0. (1861.)

Hab. — California, (Coll. Tryon Reakirt.) 



" Texas, Kansas, California," Edwards. 

 I am unacquainted with this species from Colorado. 



Eresia mata nov. sp. 



Hab. — Rocky Mountains, Colorado Terr., (Coll. Tryon Reakirt.) 



The marginal row of lunules, upon the fore wings is complete, ex- 

 tending from margin to margin ; the two inner bauds are continuous, 

 broad, and of ecpual width ; the three, occupying the outer half of the 

 surface, traversed by two narrow black strigae. 



Disposition of markings upon the hind wings, and underneath upon 

 both wings, are similar to Campestris but somewhat enlarged. 



The colors of the various pale bands, spots, &c, have unfortunately 

 been bleached to a pure white; nothing but their outlines remaining 

 to determine the species, but I am of the opiuion, that these are 

 sufficiently at variance with its allies, to establish its specific dis- 

 tinctiveness.
