Additions and Corrections to the List of 

 Southern California Butterflies. 



By Fordyce Grinnell, Ji\ 



In the Bulletin of the Southern California Academy of 

 Sciences, Vol. IV. No. 3, March 1905, Prof. J. J. Rivers gives 

 a list of butterflies found within the area of Southern Cali- 

 fornia, in which are enumerated 107 species. A number of 

 the species have since been found to have been wrongly deter- 

 mined, partly due to the author of the present paper; since 

 then a number of important books and papers have been 

 published and more collecting done, so that it is time that a 

 supplement to this list be published. 



W. Gr. Wright's Butterflies of the West Coast, issued in 

 October 1905, notwithstanding its many errors, idiosyncrasies, 

 etc., added a lot of information on the Californian butterflies, 

 prompted more work, and will become a classic. Grinnell 

 & Grinnell, in the Journal of the New York Entomological 

 Society, XV, 1, 37-19, 1907, published a paper on the butter- 

 flies of the San Bernardino Mountains, California. W. S. 

 Wright in the same Journal published an Annotated List of 

 the Diurnal Lepidoptera of San Diego County, California, 

 based on collections during 1906-1907, XVI, 3, pages 153-167, 

 1908, a useful paper. Dr. Henry Skinner in Entomological 

 News. XVIII, 9. 378, 1907, describes Thecla loki, n. sp. from 

 San Diego County. And a few other short notes and papers. 

 With the collections of Mr. V. L. Clemence, Mr. K. R. Coolidge, 

 Mr. W. S. Wright and others, the butterflies are becoming 

 better known, but there are still many vexing problems to 

 solve, and with every addition to knowledge, more problems 

 and complications arise. 



In the following list I will give the additions and correc- 

 tions to Prof. Rivers' list which occur to me. and hope it 

 will be a spur to future work and more lists. Dr. Dyar's 

 generic arrangement is adhered to as in the previous list, but 

 in his A Review' of the Hesperidae of the United States, of 

 1905, a number of generic names are changed. In the summer 

 of 1908, the author spent three months in the San Jacinto 

 and Santa Rosa Mountains, and a number of interesting points 

 in distribution noted. 



Papilio indra Reakirt. Should be stricken from the list. 

 It is a Northern California species. P. Pergamus is its South- 

 ern representative. 



Papilio coloro n. var. of Wright's Butterflies is a synonym 

 of Zolicaon.
