Explanatory Notes on North American 

 Malacosoma Types 



Neotype designation of Malacosoma calijornicum (Packard) 



In 1864 Alpheus S. Packard described a species of Malacosoma 

 under the name Clisiocampa calijornica from specimens sent to him 

 from California by "Mr. Edwards." This "Mr. Edwards" was un- 

 doubtedly Henry Edwards, since he had visited California as an actor 

 before 1864 and lived there from 1865 to 1878 (Essig, 1931). In addition, 

 he was especially interested in moths, while the other "Mr. Edwards" 

 actively working on Lepidoptera at that time was W. H. Edwards, who 

 spent most of his life in the East and was an authority on butterflies. 



The type of Af. calijornicum (Packard), if one was designated, appears 

 to be lost or destroyed. A personal search of the Malacosoma in the 

 United States National Museum, the American Museum of Natural 

 History, the Carnegie Museum, and the Chicago Museum of Natural 

 History did not reveal any specimen which had labels indicating it 

 could be the type. 



The Museum of Comparative Zoology at Harvard University, the 

 Academy of Natural Sciences of Philadelphia, the New York State 

 Museum, the Boston Museum of Science (formerly the Boston Society of 

 Natural History), the Northeastern Forest Experiment Station, the 

 University of Connecticut, the Connecticut Agricultural Experiment 

 Station, Cornell University, and Rutgers University all indicate they 

 do not have it. It is not among any of the specimens borrowed from 

 various other institutions, and these institutions have not indicated 

 that they have any types of Malacosoma. 



Dr. Packard was Professor of Zoology and Geology at Brown Uni- 

 versity from 1878 until his death, but Dr. J. Walter Wilson of the 

 Biological Laboratory at Brown University states that if the type 

 was ever in Packard's collection at Brown University, it has long 

 since disappeared, for after his death in 1905 the museum was
