in the submarginal line which, instead of being deeply dentate as in 

 the California species, has a tendency in the Northern form to lose 

 this dentation, the line being a series of loops bent outwardly with, 

 in some cases, a slight dentation between the veins. 



As the assembling of a large series of this genus is very cumber- 

 some, may I ask some of our readers to send me particulars as to 

 how far south this variety occurs? I have frequently been met with 

 remarks from collectors to whom I have sent this form of rubra that it 

 was nearer to gloveri than to the generally recognized form of rubra, 

 but the two species are sufficiently distinct in the median lines to pre- 

 vent any possibility of a mistake, but at the same time the northern 

 form of rubra is so different in appearance to warrant a separation 

 and possibly, when the investigation is carried to completion, even 

 a new name. 



Living away from all sources of information, I am not in a posi- 

 tion to examine the types of ceanothi, californica and euryalus, which 

 Dyar gives as synonymous. Possibly some of these may have had 

 more warrant for being considered good species than is at present 

 accorded them. J. WM. COCKLE, Kaslo, B. C. 



NOTES ON EREBIA AND EREBUS. In my list of the species of this genus, 

 the references to the immature stages were omitted. The life-history of 

 but two of our species have been described and one of these incompletely. 

 Tn his Butt. N. Am., Vol. Ill, W. H. Edwards minutely described 

 the preparatory stages of E. cpipsodca and later H. H. Lyman (Can. 

 Ent., Vol. XXVIII, p. 274) published the life-history of the same 

 species, his descriptions differing somewhat from those of Edwards. 

 The former writer has also partially described and figured the early 

 stages of E. magdalcna. Thus it can easily be seen how much more 

 remains to be learned of the immature stages of Erebia and careful 

 breeding, I think, will eliminate several of our forms. 



The egg of Erebia is subconical in shape and irregularly marked 

 with numerous raised vertical ridges. The larva, which feeds ex- 

 clusively on grass, is cylindrical, tapering somewhat posteriorly, and 

 the caudal segment, as in others of the Satyridac. is bifurcate. 



The pupa is usually of some shade of brown or gray, with the 

 markings darker than the ground color. 



It is convex, dorsally and ventrally, and somewhat produced at 

 the head. Pupation takes place freely about the roots of grass or on 

 the ground. 



Several of our species as they now stand in our catalogues are 

 hardly worthy of specific rank. The number of the ocelli and the 

 degree of mottling on the inferior surface of the secondaries I would 

 not consider of sufficient value for distinguishing species as in both 

 cases variation tends to be extreme.
