Arctiidae 
Genus EMILIA Kirby 
A small neotropical genus, represented in our fauna by two 
species. The insect named occidentals by French is a form of 
A. roseata , in which the red of the wings has been replaced by 
ochreous. 
(1) Emilia ambigua Strecker, Plate XIV, Fig. 15, $. 
(The Red-banded /Emilia.) 
Syn. bolteri Henry Edwards; syracosia Druce. 
This beautiful insect is found in the Rocky Mountains of 
Colorado, and thence southward to northern Mexico. 
(2) /Emilia roseata Walker, Plate XIV, Fig. 14. ?. (The 
Rosy /Emilia.) 
Syn. cmnamomea Boisduval; sanguivenosa Neumoegen; significans 
Henry Edwards; occidentalis French. 
This rather rare insect occurs on the Pacific coast, 
and, according to report, ranges from British Columbia to 
Mexico. The specimen figured on the pkte came from the 
latter country. 
Genus HALISIDOTA Hiibner 
An extensive genu$, 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. 
(1) Halisidota tessellaris Abbot & Smith, Plate XIV, Fig. 
12, $ . (The Tessellated Halisidota ) 
Syn. antiphola 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 larvae, 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 XI V, Fig. 13, $. 
(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
