Hagen.] 170 [December 27, 



This species has not been figured, but I had the privilege to see 

 the types, and have before me a male presented to the Museum 

 by Mr. H. Edwards. The species is described as most nearly 

 allied to the original types of C. occidentalis of Mr. W. H. 

 Edwards. What those types are becomes more doubtful by this 

 statement, as the figures of C. occidentalis and the description 

 show indeed no palpable similarity with C. Chrysomelas. The 

 species were collected in Napa Co., Cala. 



A careful comparison of the male type before me shows it to be 

 identical with the C. Philodice collected in Washington Territory 

 at different localities along the Yakima River. I have no female 

 type. 



In the males of C. Chrysomelas the discal spot of the primaries 

 varies from a small dot to a larger one. I cannot find any other 

 difference between the typical C. Chrysomelas and C. Philodice. 

 One male presented to the Museum by Mr. W. H. Edwards from 

 Coalburgh, W. Va., is above and below not different from C. 

 Chrysomelas ; the black marginal band is cut on both wings by 

 yellow veins ; the small discal spot is only surrounded by a very 

 few more black scales. In consequence of this the species must 

 be considered as C. Philodice till more sufficient information is at 

 hand. All females of C. Chrysomelas were pale yellow, and no 

 albino was seen. 



Colias Palaeno. 



The European literature is very large and can be found in the 

 works of Ochsenheimer and Staudinger. C. Palaeno is a northern 

 species and lives along the shore of the Baltic and in Scandinavia 

 in swamps. More to the south and west it appears only at higher 

 elevations in the mountains (cf. Speyer, Geogr. Verbr., Vol. 1, p. 

 266) ; Lacordaire's statement, Introd., Vol. n, p. 603, that Palaeno 

 is common in Iceland is apparently a mistake ; probably Mr. 

 Lefebvre is his authority for this statement. C. Palaeno was first 

 described by Uddman without name in Novae Ins. Spec. 1733, 

 p. 28, and later by Linnaeus. He says the caterpillar lives on 

 Pteris aquilina. Esper, Suppl. i, p. 42 in a communication from 

 Pommerania describes the egg on Vaccinium uliginosum. The 

 caterpillar hatches the third or fourth day and is yellow with black- 

 ish bristles, and feeds only on the plant mentioned. After the first
