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 Gceze: plantaginis Martyn; dodgei Butler; excelsa 

 Neumoegen; favorita 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. \2, $, 

 (The Figured Tiger-moth.) 



Syn. cer arnica 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, 6, 

 Fig. 22, ? . (Banded Tiger-moth.) 



Syn. decor ata Saunders. 



Form radians Walker, Plate XV, Fig. 25, $, Fig. 21 $. 



Syn. color ala 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.
