280 PROCEEDINGS OP THE CALIFORNIA 



This species is the only California!! yet known that approaches the type of 

 the European species L. Arion, L. Euphemus, L. Mas, L. Alcon, L. Erebus. 

 It approaches most nearly to L. Alcon of Europe, and is intermediate between 

 that and the European L. Acis. 



The only habitat of this species yet known to me, is in the Contra Costa 

 Coast Range, in the vicinity of San Antonio, where it frequents steep, grassy 

 hill-sides. It is found at the end of May and beginning of June, and is rather 

 rare. 



2. L. Antiacis, Boisd. May. Different localities. 



3. L. Xerxes, Boisd. May. Lone Mountain, near San Francisco ; rather 

 rare. 



There exists no European analogue to this very peculiar type. 



4. L. Piasus, Boisd. Very common throughout middle California. It re- 

 places the Atlantic L. Pseudargiolus, and L. neglecta, Edw., as well as the 

 European L. Argiolus ; and belongs to one of the most cosmopolitan types 

 of the genus. The caterpillar feeds on the flowers of the Pavia, unlike its 

 European representative, which feeds on the leaves of Rhamnus frangula. 



5. L. Pheres, Boisd. May and June. Lone Mountain, near San Francisco. 

 I do not know of any other locality. 



6. L. Heteronea, Boisd. Several localities. May and "June. Likes to 

 repose on Eriogonum, and is only to be found where some species of this genus 

 is abundant. Probably the caterpillar feeds on the flower of this plant. This 

 species is a very fine analogue of the L. Daphnis of Europe.

I possess a pair of this Lyccena, through the kindness of our celebrated 

 entomologist, Mr. Lorquin, who caught the species in the higher Sierra Nevada. 



8. L. Icarioides, Boisd. May and June, Marin County. 



9. L. Dcedalus, Behr. 



Icarioidi similis sed subtus, quae puncta in Icarioide sunt rotundissima, in 

 Daedalo sunt transverse producta, lineaque discoiclalis alarum posticarum, 

 qua3 in Icarioide deest et pro qua macula alba subtriquetra militat, hac in specie 

 linea transversa distinctissime nigra viudicatur. 



The three specimens in my collection, I received through the kindness of Mr. 

 Chas. Hoffman, of the Geological Survey, who collected them in the Alpine 

 regions around the head waters of the Tuolumne River.
