much the same manner that the presence there of Chionobas seniidea 

 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 

 Enghand. The insects of this group are rather phiin yellowish 

 brown butterflies, with brown and black markings, liaving no silvery 

 spots on the nnder side, and in this respect showing a strong contrast 

 to most of the species of Arg7/7inis, their near relatives. Tlieir larvcC 

 are adorned with rows of short black Ijranching spines, the ones near 

 the head being the longest and are directed forward. They feed on 

 the leaves of the passion vine. 



Euptoieta ehmdia 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 manj^ specimens in the latter part of July. 

 The larva of this species is ])ro\vnish orange striped with brown and 

 S[)otted with white on tlie Ijack. The chrysalis is light gray spotted 

 and streaked with black. The insect is an iidiabitant 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 tro[)ical and subtropical parts of America. 

 Their coloring above is tawny orange or reddish orange marked with 

 black, wliile l)elow it is lighter, in some species liaving a decided 

 pink tinge near the Ijase of the upper wings, while mau}^ brilliant 

 silvery spots adorn botli sets of wings. Tlie larvse are armed with 

 branching spines, and tliey feed on the various species of tlie passion 

 vine. 



I)ut one species occurs within tlie bortlers of this country. This 

 is Af/raulis vaniUce, 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 Yiiginia 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 Cohcnis has very long and narrow upper wings, re- 

 sembling in this respect the genus HeUronia. The insects are mostly 

 brownish orange, but one very beautiful species, Colcenis dido, is
