Arctiidae 
As the name indicates, this species is an inhabitant of the 
Rocky Mountains. 
(14) Apantesis williamsi Dodge. (Williams’Tiger-moth.) 
Form determinata Neumoegen, Plate XV., Fig. 3, $ . 
Syn. diecki Neumoegen. 
This easily recognized species is found in Colorado and 
adjacent States among the mountains. 
(15) Apantesis phyllira Drury, Plate XV, Fig. 14, $. 
(The Phyllira Moth.) 
Syn. B-atra Goeze: plantaginis Martyn; dodgei Butler; excelsa 
Neumoegen; javorita Neumoegen; lugubris Hulst. 
This species is found in the Southern States, where it is 
not uncommon, it is rather variable in the disposition and 
extent of the dark and light markings. 
(16) Apantesis figurata Drury, Plate XV, Fig. 12, $, 
(The Figured Tiger-moth.) 
Syn. cerarnica Hubner; f-pallida Strecker 
This is probably only a form of the preceding species, 
which occurs with considerable frequency. It is confined to 
the Southern States. 
(17) Apantesis vittata Fabricius, Plate XV, Fig. 25, &, 
Fig. 22, $ . (Banded Tiger-moth.) 
Syn. decorata Saunders. 
Form radians Walker, Plate XV, Fig. 23, 6 , Fig. 21 $. 
Syn. colorala Walker; incompleta Butler. 
Form phalerata Harris, Plate XV, Fig. 6, ? . 
Syn. rhoda Butler. 
A very common and variable species, which is probably 
the same as A. nais Drury, which has the abdomen preva¬ 
lently ochraceous, and not as strongly marked with black. 
The species seems to be, so to speak, in a liquid state. In 
a series of some hundreds of specimens before the writer, 
many of them bred from larvae, and undoubtedly all referable 
to the same species, any and all of the forms, which have 
been named by writers, can be found, yet the bulk of them 
came from one narrow little ravine in western Pennsylvania. 
We leave the synonymy as it stands in Dyar’s list, so far as 
the things figured on our plate are concerned, but cannot believe 
that these insects represent different species, as maintained by 
some authors.
