NOTES ON BRITISH LEPIDOFTERA. 141 



In entering upon the discussion of the results accruing 

 from the labours of the past season, I purpose following the 

 programme of the preceding Annual, and shall commence 

 with a few notes on points of interest which have arisen, 

 passing on to the New species, Tables of local species cap- 

 tured, Larv82 discovered, &c. 



Erebia Epiphron, Knock, and E. Cassiope, Fabr. 



There has been from the time of Fabricius a decided 

 tendency to consider these as distinct species ; most authors 

 recognising as a particular feature in Cassiope the absence of 

 the white spots in the ocelli (^ocelli's nigris ccecis)^ and accept- 

 ing it as a sufficient and constant character by which the 

 two could, and can, be separated. Be this as it may, 

 modern authors appear to have arrived at the conclusion, 

 that they are identical — merely varieties — and our old 

 familiar name of Cassiope has been sunk, in Dr. Staudinger's 

 Catalogue, and also in the Supplement to Mr. Doubleday's 

 Synonymic List, before the Epiphron of Knock's "Beitrage 

 zur Insektenkunde," the latter having about ten years' pri- 

 ority over the Fabrician name. 



Ccenonympha Davus, Fabr., and C. Typhon, Haworth. 



Attempts have been made at various times to secure for 

 Haworth's TypJion the rank of a species, and certainly his 

 insect appears, to my fancy, distinct enough from the Davus 

 of Fabricius — the Rothliehii of continental writers — the 

 Daims of our northern counties; but the variations are 

 such as to cause our high authorities to pause before ad- 

 mitting their distinctness. This interesting problem will, 

 doubtless, be satisfactorily cleared up at no distant period by 

 careful comparison of the respective larvae; much attention 

 having already been bestowed upon the subject during the
