tributed, but confined to circumscribed localities, scattered here and 
there over a wide region ; but wherever one is found, there surely is 
to be seen its companion species. In another instance of inseparable 
species, namely, Heliconius Doris and H. Erato, I found by rearing the 
two from the same brood of caterpillars that they were two forms of 
one species only. I cannot think, however, that this will prove to 
be the case with Eresia Nauplia and E. Clara, or with Dircenna Rheo 
and D. Epidero ; for the points of difference in both these instances are 
multiple, instead of consisting of a mere substitution of colour, as in 
Heliconius Doris and H. Erato. 
In a large collection of butterflies lately made in Guatemala by 
Mr. Osbert Salvin, I find many examples of Hresia Clara, but none 
of H. Nauplia ; so that here one only of the companion forms appears 
-to occur. 
Genus AnarTia (Hiibn.), Doubleday. 
A group peculiar to Tropical America, and not very closely related 
to any other known genus. Its nearest affinity seems to be with 
Oynthia, a genus peculiar to South-eastern Asia. The species have 
the habits and mode of flight of the Vanesse and Junonia, and are 
found only in open, weedy, and bushy places, chiefly in the neigh- 
bourhood of towns. 
15, Anartia Jatrophe, UL. 
A very common insect in all waste places thro®ghout the country. 
It seems to be equally common throughout the whole of Tropical 
America, undergoing scarcely any local modification. 
16. Anartia Amalthea, L.; Clerck, Icon. pl. 40. f. 3. 
Also a common insect, preferring, however, the moister districts. 
It extends southward as far as 50° S. lat., undergoing some little 
local modification. 
Genus JunoniA (Hiibn.), Doubleday. 
The Junonie are chiefly an old-world group, their metropolis being 
South-eastern Africa, with Madagascar ; although one or more species 
occur in the hot zones of the whole world. They are amongst the 
most richly ornamented of the whole section of Diurnal Lepidoptera, 
and are closely related to Pyrameis, the genus which embraces our 
Red Admiral and Painted Lady butterflies. The species are very 
similar in habits and mode of flight to these familiar insects, and to 
the Vanesse ; having very little of the floating motion of the typical 
Nymphaline, and flying near the ground in open, flowery, and bushy
