485. Hemileuca Nevadensis. Elsewhere illustrated only by 



Stretch, the Author of the species. 

 Plate XXXII ; Figure 485, Male, Dayton, Nevada, 

 August, 1872. 



Figure 485 is a photograph of the uncolored lithographic figure 

 by Mr. Stretch, the Author of Nevadensis, issued in 1872. I copy 

 as follows from the text: "Both wings in Nevadensis are black 

 and pale yellowish ; the discal lunule of fore wing is transverse, 

 long and narrow, surrounded by a blackish halo, with a whitish 

 transverse center; hind wings, discal spot dusky, small, with 

 whitish transverse center. Described from two males taken at 

 Dayton, Nevada, in August. Though apparently not rare in 

 Nevada, this insect has not been detected in California." (Zygae- 

 nidse and Bomdycidse of North America, by R. H. Stretch, Parts 

 I to 9, 1872 to 1873. Plate 4, page 108.) The discovery of 

 Nevadensis is not dated exactly, but it must have been in 1872, I 

 think. Californica was first seen by me in 1873, though not col- 

 lected for distribution till a few years later. 



In comparing these different forms, it should be borne in mind 

 that my figure of Nevadensis is copied from an uncolored litho- 

 graph, and so the wings are represented as being white ; while the 

 text describes the color as "yellowish." Nevadensis is yellowish, 

 and Californica is white.

This is a local form, flying in October and November. When 



I first discovered Californica, in 1873, I was not then ac-
