Timetes Tutelina, Wewits. Exot. Butt. Tim. f. 5,3. 
This elegant species was abundant at St. Paulo, on the Upper 
Amazons, settling on the sandy margins of brooks in the heart of the 
forest. I saw it once also at Ega.

Genus Hrrrrocnroa (Boisd.). 
Westwood, in Doubld. & Hewits. Gen. p. 276. 
This genus is the representative of Zimenitis of the Old World 
and north temperate parts of the New World. The species have the 
same habits and a similar bold, sailing manner of flight. There is no 
structural difference between them; but the different style of colora- 
ration presented by the two groups warrants their generic separation. 
About forty-seven species of Heterochroa have been described, and 
about thirty-two of Limenitis. The only species which seem inter- 
mediate between the two genera are H. Bredowii and H. Lorquinii, 
both natives of California. 
125. Heterochroa Thoasa, Hewitson. 
Heterochroa Thoasa, Hewits. Annals & Mag. Nat. Hist, vol. vi. n. s. 
p- 436, pl. xi. f. 6. 
A rare and beautiful little species, approaching in its colours the 
Pyrrhogyre. I met with it only on the Lower Amazons—at Para, 
on the banks of the Tapajos, and at Villa Nova. Like all the other 
members of the genus, it is a forest insect, emerging only in sunny 
places to settle on moist places on the ground, whence, if disturbed, 
it ascends rapidly to the summit of trees.

This species was described, in the place quoted, from examples 
captured by Mr. Salvin in Guatemala. It is found sparingly through- 
out the Amazons region, and probably in most other parts of Tropical 
America. The nearest allied species described is H. Serpa of Bois- 
duval, from which it differs in the green tinge of the pale belt of the
