Enumeration of the Californian species of LycaBna. 



BY H. BEHR, M. D. 



The genus Lyccena is much more extensively represented in California than 

 in the Atlantic States, where, with the exception of a few Arctic species, 

 only the most cosmopolitan types are represented, such as that of Argiolus and 

 that of Amyntas. 



California has about the same number of species as a corresponding area in 

 the Mediterranean basin. The species are never identical with gerontogeic forms ; 

 but there is scarcely a single European type that does not find its analogue on 

 the Pacific coast : a circumstance of which the celebrated lepidopterologist, 

 Dr. Boisduval, has made good use in naming many Californian species with 

 reference to the best known European species of the same type, thus : 



Europe. California.
