Genus Terias 
extends inwardly beyond the angulated point of the wing, and 
by the different color and style of the markings of the lower side. 
Expanse, 1.35-1.65 inch. 
Early Stages.- —Unknown. 
Damaris occurs in Arizona, and thence ranges south into 
Venezuela. 
(6) Terias westwoodi, Boisduval, Plate XXXVII, Fig. 11, $ 
(Westwood’s Yellow). 
Butterfly .—Pale yellow or orange-yellow, with a narrow 
black border on the fore wings, beginning on the costa beyond 
the middle, and not quite reaching the inner angle. On the 
under side the wings are pale yellow, immaculate, or at the apex 
of the fore wing and the outer angle of the hind wing broadly 
marked with very pale reddish-brown. Expanse, 1.75-2.00 inches. 
Early Stages. —Unknown. 
Westwood’s Yellow occurs in Texas and Arizona, but is not 
common. It is abundant farther south. 
(7) Terias lisa, Boisduval and Leconte, Plate XXXVII, Fig. 
13, $ ; Plate II, Fig. 3, larva; Plate V, Fig. 56, chrysalis (The 
Little Sulphur). 
Butterfly. —Allied to the three following species, from which 
it may at once be distinguished by the absence of the black bar 
on the inner margin of the fore wings and by the profusely 
mottled surface of the under side of the hind wings. It is subject 
to considerable variation, albino females and melanic males being 
sometimes found, as well as dwarfed specimens of very small 
size. Expanse, 1.25-1.60 inch. 
Early Stages. —These have not been thoroughly studied and 
described, in spite of the fact that the insect is very common in 
many easily accessible localities. The caterpillar feeds on Cassia 
and on clover. 
T. lisa ranges from New England south and west as far as the 
foot-hills of the Rocky Mountains, and into Mexico and Honduras. 
It is found in the Antilles and Bermuda. An interesting account 
of the appearance of a vast swarm of these butterflies in the 
Bermudas is given by Jones in “ Psyche,” vol. i, p. 121: 
“Early in the morning of the first day of October last year 
(1874), several persons living on the north side of the main isl¬ 
and perceived, as they thought, a cloud coming over from the 
northwest, which drew nearer and nearer to the shore, on reach-
