164 PROCEEDINGS OF THE CALIFORNIA 



Sattrus Boopis Behr. 



Sthenele similis at limbus noa tesselatus, sed linea transversa distinete par- 

 titus et fceminae ocelli alarum superiorum in fascia dilution positi. Alae sub- 

 tusdimidiate pars radicalis brunnea, marginalis grisea, marginem versus brur- 

 nescens. Utraque marinorata, balone ocellorum in alis antids solo excepto 

 dilution et concolori. 



This Satyrus is the biggest of our Californian species, the male being nearly 

 double the size of the female of S. Sylveslris. I find this Satyrus in July in Con- 

 tra Costa, on the hills as well as on the plains. In regard to the diagnosis of 

 these three closely allied species, I would mention, that the presence or ab- 

 sence of one or two more or less distinct eye-marks, on the upper or under 

 side near the anal angle of the hind wings, is of no diagnostic importance. 



S. Ariane Boisd. 



I confess I can not find any constant mark of difference between this species 

 and S. Alope, Nephele, and Peyala, however different at first glance their forms 

 may appear. I am very much inclined to consider them local aberrations of 

 one far spread species, that gradually slopes from S. Peyala Fabr., through 5. 

 Ariane Boisd. to S. Nephele and S. Alope Fabr., in a similar way as the Geronto- 

 geic P. Eyeria L. looks very different from its African form P. Xiphia Fabr., 

 with which, nevertheless, it is insensibly united by its intermediate form P. 

 Meone. 



All my Californian specimens agree perfectly with Dr. Boisduval's diagnosis 

 of S. Ariane; with the exception of one that approaches to S. Peyala, by its 

 having only one eye-mark on the upper side of the anterior wings, but differs 

 by the entire absence of the wide rusty band on the same. The specimen 

 was among several undoubted S. Ariane, caught near Mono Lake, by Prof. 

 Brewer, of the State Geological Survey. Besides the above mentioned locali- 

 ty, I received specimens from San Diego and Santa Cruz. Near San Francisco 

 the species is wanting. 



As to S. Sthenele and S. Sylvestris, I entertain no doubts regarding their 

 rights as distinct species, but S. Boopis being only distinguished by the ab- 

 sence of the series of eyes on the under side of the hind wings from S. Ne- 

 pkele, may, perhaps, prove a local variety or aberration of that most polymor- 

 phous and far spread species S. Alope. In the mean time, until the connecting 

 forms are found, I consider it to be specifically distinct. 



Coenonympha Hubner. 



C. Galactina. Boisd. 



I consider this species as identical with C. Californiea Dbld. At least I find 

 in a long series of specimens, no point where Californiea ends and Galactina 

 begins. C. Galactina, according to Boisduval, exists also in Kamtschatka. In 

 California it is one of the commonest species of Diurnals, and is found in the 

 most different localities, in several generations throughout the year. There 

 exists a second Coenonympha in some sequestered valleys of the Northern Sier- 

 ra, that approaches in its coloration, the European C. Pamphilas. I have only
