Butterfly. —Small butterflies, closely resembling the species of 
the genus Phyciodes in the neuration of the wings, and only differ¬ 
ing from them in the outline of the outer margin of the primaries, 
which are more or less excavated about the mid¬ 
dle. In the style of the markings they differ 
somewhat widely from the butterflies of the genus 
Phyciodes, notably in the absence of the crescents 
on the margins of the wings. The wings on the 
upper side are generally some shade of deep brown 
or black, marked with spots and bands of white 
or fulvous, the median band on the hind wings 
being generally more or less conspicuous. In the Fig. 93.—Neu- 
pattern of their markings they illustrate a transition ration of the genus 
from the genus Phyciodes to the genus Synchloe. fnterged. shshtly 
Egg. —Hitherto undescribed. 
Caterpillar.— Cylindrical, with seven rows of spines, one 
dorsal, and three lateral on each side; the spines are short, blunt, 
and armed with short bristles. The head is subcordate, with the 
vertices rounded. It moults four times. 
Chrysalis. —Cylindrical, abdomen stout, head-case short, bev¬ 
eled, nearly square at top, the vertices pyramidal. There are 
three rows of small tubercles on the dorsal side of the abdo¬ 
men. 
The caterpillars so far as known feed upon various Compositce, 
as Diclippa and Actinomeris. 
The genus, which is somewhat doubtfully separable from Phy¬ 
ciodes, and probably possesses only subgeneric value, is well 
represented in Central and South America. But three species 
are found in the faunal region of which this book treats.

Butterfly. —Upper side reddish-fulvous, clouded with fuscous 
at the base. On the basal area are waved black lines, separate 
on the hind wings, more or less blended on the fore wings. 
The outer border is broadly black. Between this border and 
the basal third the wing is, crossed by irregular black bands, the 
spaces between which are paler fulvous than the base and the 
hind wings, those near the outer margin being whitish. These
