Saturn iidae 



in a long series of specimens collected in the same locality. I 

 have one or two fine melanic specimens, in which the wings are 

 almost wholly black on the upper side. Albino specimens are 

 also occasionally found. 



Genus SATURNIA Schrank 



This genus is represented in our fauna by a single species. 



(i) Saturnia mendocino Behrens, Plate XII, Fig. 6, $. 

 (The Mendocino Silk-moth.) 



The insect inhabits northern California, where it is not 

 uncommon. The larva feeds upon Arctostaphylos tomentosa. 



Genus AUTOMERIS Hxibner 



Four species of this genus occur within our borders. Three 

 of them we figure on our plates. The other, Automeris ^elleri 

 Grote & Robinson, may be distinguished from those we give by 

 its much greater size, the female expanding fully five inches 

 across the wings, and having three broad brown bands parallel 

 to the margin of the hind wing, a large blind ocellus in the 

 middle of that wing, and the fore wings purplish brown, marked 

 with darker brown spots at the base, the end of the cell, and on 

 the limbal area. 



(1) Automeris pamina Neumoegen, Plate IX, Fig. 6, $. 

 (The Pamina Moth.) 



The figure we give is taken from an example of the form 

 called aurosea by Neumcegen, in which the hairs along the inner 

 margin of the hind wings are somewhat more broadly rosy red 

 than in the specimens which he indicated as typical. The 

 specimen was labeled by, and obtained from, the author of the 

 species. 



(2) Automeris zephyria Grote, Plate VIII, Fig. 5, ? . 

 (The Zephyr Silk-moth.) 



This beautiful insect which is found in New Mexico, is well 

 delineated in our plate, and may easily be discriminated from 

 other species by the white transverse lines of the fore wings. 



(3) Automeris io Fabricius, Plate IX, Fig. 4, $ , Fig. 5, $ . 

 (The Io Moth.) 



Syn. corollaria Perry; varta, Walker; fabricii, Boisduval; argus 

 Neumoegen & Dyar.
