SAMIA EURYALUS BDV., THE CORRECT NAME FOR THE 

 CALIFORNIAN SILK WORM MOTH. 



BY J. McDUNNOUGH, PH.D.,* 

 Entomological Branch, Ottawa. 



A curious error has crept into the synonymy of the well-known Sauiia 

 species of California and the Pacific Coast which, for the past fifteen years, has 

 been generally known as Samia rubra Behr. 



The species was first mentioned by Dr. Behr at the meeting of the 

 California Academy of Sciences held April 30th, 1855, and is reported in the 

 Proceedings of that Society, Vol. I., p. 47 (Edition of 1873, p. 46) as follows:— 

 "Dr. Behr presented a drawing of a native silk-worm of California w^ith a 

 specimen of the cocoon and the following description: Saturnia rubra, collare 



album, etc It is found on the Ceanothus thrysiflorus . . . ." Owing 



to an oversight of the author or of the i)rinter, no actual name for the species 

 was proposed, the adjective "rubra" being merely part of the Latin diagnosis 

 (as can be readily seen by the diflference in type) and by no means to be em- 

 ployed as the name of the species. Dr. Behr several times expressed himself 

 to this efifect in letters to contemporary entomologists.
