8 THE CANADIAN ENTOMOLOGIST. 



and slept. This is like the behaviour of Nycteis, as related by me in 

 Gan. Ent., XL, I02, 1879, only that Nycteis hibernated after second 

 moult, instead of third. In Nycteis (p. J04, 1. c), of 92 larvte of. the June 

 brood, 32 or about one-third hibernated, while- the rest went on to pupa- 

 tion. Of II Carlota, from Montana, of July brood (probably the first 

 brood), about two-thirds hibernated; of the August brood (probably .the 

 second), all hibernated. The larvae from Colorado, of September (the 

 last brood of the year), all hibernated. As fresh examples were taken at 

 Coalburgh 3rd May and 17th July, there is evidence of two broods at 

 least. 



I gave these larvae leaves of Actinomeris squarosa, the food of 

 Nycteis, and of the Aster, the food of Tharos, but they refused both and 

 fed only on sunflower. 



NOTE ON COPIDRYAS PLATENSIS. 



BY A. R. GROTE, A. M. 



I have suggested in " Papilio" that this South American species 

 belongs to Copidryas, and is congeneric with our C. Gloveri. Berg's 

 original description says of the frontal structure : — " Fronte valde pro- 

 minenti, supra cornu complanato depressione declivi marginata fusca 

 ornata." This character agrees well with Copidryas, but not with Eudryas^ 

 in which latter the front is not horned. 



Of the colours of Platensis, Berg says, the hind-wings are ochraceous 

 with broad and even pale fuscous marginal band, and compares the orna- 

 mentation with that of unio. I'here can thus be no shadow of doubt that 

 my E. cypris, with its vermilion red unhanded secondaries and related to 

 E. grata rather than to unio, is specificially and generically distinct. Berg 

 Vi?,QsEuthisanotia 'ms\.ea.6.o{ Etidryas. Hubner's genus has mixed contents, 

 and so far as I can see, from what literary material I have at hand, Bois- 

 duval was justified, in 1836, in proposing a new generic title (ox grata 

 and unio. 



Eudryas ^^y/r/.y, from Paraguay, is allied very clearly to our North 

 American E. grata; it is perhaps a still handsomer species from the red 

 colour of hind-wings and under surface. The Eudriince are generally 

 quite pretty moths, while I think the palm for beauty must lie between 

 Eudryas cypris and our North Am. Ciris Wilsoni.
