Arctiidae 



Genus iEMILIA Kirby 



A small neotropical genus, represented in our fauna by two 

 species. The insect named occidentalis by French is a form of 

 A. roseaia, in which the red of the wings has been replaced by 

 ochreous. 



(i) iEmilia ambigua Strecker, Plate XIV, Fig. 15, 3. 

 (The Red-banded Emilia.) 



Syn. bolteri Henry Edwards; syracosia Druce. 



This beautiful insect is found in the Rocky Mountains of 

 Colorado, and thence southward to northern Mexico. 



(2) iEmilia roseata Walker, Plate XIV, Fig. 14. ?. (The 

 Rosy /Emilia.) 



Syn. ctnnamomea Boisduval; sanguivenosa Neumoegen; significans 

 Henry Edwards; occidentalis French. 



This rather rare insect occurs on the Pacific coast, 

 and, according to report, ranges from British Columbia to 

 Mexico. The specimen figured on the plate came from the 

 latter country. 



Genus HALISIDOTA Hiibner 



An extensive genus, well represented in Central and South 

 America, and containing about a dozen species, which are 

 found within our faunal limits. Of these we figure a number 

 of species, enough to enable the student to recognize the genus, 

 and the commoner species, which he is likely to encounter. 



(i) Halisidota tessellaris Abbot & Smith, Plate XIV, Fig. 

 12, $ . (The Tessellated Halisidota.) 



Syn. mitiphola Walsh; harrisi Walsh. 



The form named Harrisi does not differ from tessellaris in 

 the imaginal stage. The sole difference is in the color of the 

 pencils of hairs in the larvce, which are orange in color, while 

 in tessellaris they are black. This is scarcely sufficient ground 

 upon which to establish a species. 



(2) Halisidota cinctipes Grote, Plate XIV, Fig. \}, a. 

 (The Gartered Halisidota.) 



Syn. davisi Henry Edwards. 



This species, which is southern in its habitat, and larger 

 than its close northern ally, tessellaris, has the markings on 

 the fore wings much more distinct than is the case in the latter
