Saturniidae 
in a long series of specimens collected in the same locality. 1 
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 Hubner 
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 Neumoegen, 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; vana, Walker; fabricii , Boisduval; argus 
Neumoegen & Dyar.
