A REVIPAV OF THE GENT'S CHRYSOPHAXUS. 
BY KARL R. rOOLIDGE, PALO ALTO, CALIFORNIA. 
I’oR some time the writer has been accumulating material in this genus with 
a view of monographing. Identifications of the various species of some genera 
of our Rhopalocera are often quite impossible, owing to the lack of necessarv litera- 
ture, so widely scattered. This is especially true in the west, where good entomological 
libraries are so rare. The writer believes that, if those who were working on 
any special genus or genera, would publish their results with the more important 
references, etc., our faunal knowledge would soon become much better known. In 
order to straighten out the present genus, the writer desires to obtain liy purchase, 
exchange or loan, specimens of all our Chryaophanids from various localities. 
Immature stages, abeiTations, minor variations, and specimens of zeroe and the 
hypophlcas group, are especially desirable. The genus Chrysophanus is now divided 
into six genera, several more or less superficial, viz.: Tharsalea, Gaeides, Chrysopha- 
mis, Epidemki, Ileodcs and Chalceria, but for convenience in the following brief 
synopsis, the species are listed under the one genus. 
1. arola, Boisd. This species is known, so far, only from California. It flies 
quite commonly in the vicinity of San Francisco Bay. It is closely allied to virgin- 
iensis, Edwards and may prove conspecific with it. Dyar has partially described 
the preparatory stages. The larva feeds on Ribes. 
2. Tirginicnsifi, Edwards. Found at high altitudes in Colorado, Nevada and 
California. Common at Lake Tahoe. Nothing is known of the early stages. 
3. hermes, Edw. Hermes is a rare s])ecies and is not very well known. It 
appears to be rather abundant at San Diego, California and is also reported from 
Nevada. Wright (Butterflies West Coast) redescribes it as del-sud, the specimens 
coming from the type locality. 
4. a'anthoidcs, Boisd. Another Californian species and the largest in North 
America. It was recently, however, discovered at Calgary, Canada. I have it 
from many localities in California and it is evidently widespread in its distribution 
there, occurring more commonly at fairly high altitudes. Boisduval, (Lep. de la 
Californie) writes “IMontagnes de la Californie. Rare.” Henry Edwards has 
described the egg. 
5. dione, Scudder. Ranges from Iowa to Kansas, and is also found in 
Nebraska, Montana, IManitoba, and Colorado. It comes very close to xanthoides
