ably taken at Port Townsend, at which locality Agassiz collected most 

 of his material labelled "Gulf of Georgia." These two types bear 

 out completely our remarks on the race in our Contributions Vol. Ill 

 (2) p. 58 and make it a mystery how Scudder could ever have later 

 referred the form to rapae. Our remarks on pallida Scud, in the same 

 article are also substantiated by the types which still exist in the Cam- 

 bridge Museum. 



For some reason or other ibcridis Bdv. (1869, Lep. Cal. p. 39) has 

 been omitted from all our recent catalogues and lists; the 9 type is 

 figured by Verity (Rhop. Pal. PI. XXXII, Fig. 43) and proves the 

 species to be an exact synonym of castoria Reak. Rcscdac Bdv. at 

 present listed as a further synonym was based on a yellowish-colored 

 specimen stated by Boisduval to be a 9 but figured by Verity as a 5 

 (1. c. PI. XXXIII, fig. 3) ; we believe the name should supplant flava 

 Edw., based on a yellowish 9 of pallida from Washington State ; the 

 difference between the forms pallida from northern Washington and 

 B. C. and castoria from Middle California, consisting as it does in the 

 presence of a dark subterminal spot on primaries in the $ of the 

 latter race, is so slight and apparently so inconstant that we believe 

 one name for the yellow form of both these so-called races will suffice ; 

 this yellow form also, we might note, occurs in the spring races, niar- 

 ginalis and I'ciiosa. 



EURYMUS OCCIDENTALIS Scud. 



This species has caused entomologists a good deal of perplexity ; 

 it was originally described (1861, Proc. Bost. Soc. N. H. p. 109) from 

 2 S , 3 9 , Gulf of Georgia (Agassiz) ; Fort Simpson, British Amer- 

 ica (W. H. Edwards). Hagen later (1882, Proc. Bost. Soc. N. H. p. 

 164) gives further details concerning these types and we find that of 

 the five original specimens 1 $ and 2 9 collected by Agassiz near 

 Port Townsend, Wash., on the Gulf of Georgia (thus giving a definite 

 locality for Agassiz's material labelled "Gulf of Georgia") were in 

 the Cambridge Museum and that the other S and 9 from Fort 

 Simpson were presumably in the W. H. Edwards' Collection. We 

 have recently examined the types in Cambridge and concur absolutely 

 with Dr. Hagen (1. c. p. 164) in referring the 9 's to the white form 

 of curytheme Bdv. ; the single $ specimen comes extremely close to 

 a specimen of chrysomclas Hy. Edw. from California labelled by Ed- 

 wards himself and presumably the specimen referred to by Hagen on
