ANARTIA. 221 
The variations of this species have caused it to be described many times; but with 
our long unbroken series of specimens before us we do not think it possible to separate 
more than two species. Our Costa-Rican specimens are of the usual type found in 
Central America; and we do not separate them under the names selected for them by 
Messrs. Butler and Druce * and Mr. Distant 5. 
ANARTTA. 
Anartia, Hiibner, Verz. bek. Schm. p. 33 (1816) ; Doubl. Gen. Diurn. Lep. p. 214. 
The peculiar arrangements of the subcostal branches of the primaries in the members 
of this genus render it of easy definition. Doubleday first drew attention to these 
characters, and described them with his usual care; but on one or two small points we 
find he is not quite correct, as we will shortly show. 
In Anartia iatrophe the first subcostal branch traverses the costal nervure; the 
second anastomoses with it, but does not pass out to the costa as a separate nervule. 
In A. fatima the first subcostal branch seems to be entirely absent ; the second cuts 
the costal nervure and passes beyond it. 
In A. lytrea and A. chrysopelia the second subcostal branch starts as a branch of 
the first, and does not originate from the subcostal nervure. Doubleday says that the 
first branch is wanting ; but this, so far as we can see, is not the case. 
Thus the members of the genus group themselves into three categories as regards 
their neuration, and not two as arranged in the ‘ Genera of Diurnal Lepidoptera.’ 
The front legs of the male of A. iatrophe are slightly hairy; the coxa > femur + 
trochanter; tibia=femur ; tarsus (single-jointed) < 4 tibia. The middle and posterior 
legs are spinous, and the claws moderately curved. The palpi are slender, moderately 
hairy, the terminal joint rather attenuated, and the middle joint but slightly swollen. 
The antenne have 33 joints, the terminal 9 forming a slender club. The secondary 
male organs have a tegumen with the central spine bifid for the greater part of 
its length ; the harpagones are simple, without spines or projections, and they do not 
protrude beyond the point of the tegumen. 
Anartia comprises five species, most uf which are very common insects, being inha- 
bitants of the more open country. Two species are found in our region—one, A. fatima, 
being peculiar to it, but represented in South America by A. amalthea; the other, 
A. iatrophe, is common everywhere throughout the Neotropical Region. Two other 
species are peculiar to the Antilles—A. chrysopelia belonging to Cuba, and A. lytrea 
to Haiti and Jamaica.
