much, the same manner that the presence there of Chionobas semidea 
is accounted for. 
Of the genus Euptoieta we have but one species in the United 
States. It is a southern insect and rarely gets as far north as New 
England. The insects of this group are rather plain yellowish 
brown butterflies, with brown and black markings, having no silvery 
spots on the under side, and in this respect showing a strong contrast 
to most of the species of Argynnis , their near relatives. Their larvse 
are adorned with rows of short black branching spines, the ones near 
the head being the longest and are directed forward. They feed on 
the leaves of the passion vine. 
Euptoietaclcmdia is a medium sized butterfly, very plentiful in the 
south and southwest, where it flies in open fields and along the edges 
of forests. It is very abundant in Arkansas, where along the White 
River I have captured many specimens in the latter part of July. 
The larva of this species is brownish orange striped with brown and 
spotted with white on the back. The chrysalis is light gray spotted 
and streaked with black. The insect is an inhabitant of both North 
and South America, and is often seen in collections from Brazil. 
To the genus Agraulis belong some exceedingly beautiful butter¬ 
flies of medium size. They are insects loving warm climates, and 
are very abundant in the tropical and subtropical parts of America. 
Their coloring above is tawny orange or reddish orange marked with 
black, while below it is lighter, in some species having a decided 
pink tinge near the base of the upper wings, while many brilliant 
silvery spots adorn both sets of wings. The larvse are armed with 
branching spines, and they feed on the various species of the passion 
vine. 
But one species occurs within the borders of this country. This 
is Agraulis vanillce , and one may search a good while before finding 
a handsomer insect. It is not difficult to capture, flying leisurely 
from flower to flower in search of honey. It is very abundant at 
times in the southern states, coming as far north as Virginia and the 
southern part of Illinois. It is also found on the Pacific coast in 
southern California. The larva is light yellowish brown striped 
with dark brown and covered with black branching spines. It feeds 
on the passion vine. 
The genus Colcenis has very long and narrow upper wings, re¬ 
sembling in this respect the genus Heliconia. The insects are mostly 
brownish orange, but one very beautiful species, Colcenis dido , is
