Arctiidae 



species. The tarsi are annulated with black bands, marked 

 with small gray points. The insect occurs in the Gulf States 

 and in South and Central America. 



(3) Halisidota maculata Harris, Plate XVI, Fig. 11, 3. 

 (The Spotted Halisidota.) 



Syn. fulvoflava Walker; guttijera Herrich-Schseffer. 



This species, which occurs in the northern portions of the 

 Atlantic coast region, ranges westward to California. Several 

 forms from the western territory have been discriminated by 

 writers, and varietal names have been given to them. They are 

 mere color forms. 



(4) Halisidota longa Grote, Plate XIV, Fig. 16, ?. (The 

 Long-streaked Halisidota). 



This species, which may easily be determined by the help 

 of the figure we have given, occurs in Florida. The specimen 

 delineated by the writer was taken by him at light in 

 Jacksonville in the month of February. 



(5) Halisidota caryae Harris, Plate XIV, Fig. 10, 5 . (The 

 Hickory Halisidota.) 



Syn. a)inulifascia Walker; porphyria Herrich-Schseffer. 



This well-marked and easily identified species is common 

 in the northern Atlantic coast region, and ranges westward 

 into the valley of the Mississippi. 



(6) Halisidota argentata Packard, Plate XIV, Fig. 8, i , 

 Fig. 9, $ . (The Silver-spotted Halisidota.) 



This pretty species is found in Colorado, and thence west- 

 ward and northward to the Pacific coast. A number of sub- 

 species have been named in this connection, but it is doubtful 

 whether the sexes of the insects on meeting each other would 

 recognize any specific differences themselves. 



Genus HEMIHYALEA Hampson 



Two species of this genus occur within the limits of the 

 United States. Edwardsi is distinguished from Idbecula most 

 easily by the fact that the inner margin of the secondaries in 

 the former is crimson, while in the latter it is not. 



(1) Hemihyalea edwardsi Packard, Plate XIV, Fig. 6, ?. 

 (Edwards' Glassy- wing.) 



Syn. translucida Walker; quercus Boisduval. 



This is a Californian species.
