ZOOLOGICAL GEOGRAPHY. 
[part in. 
The butterflies of this sub-region, according to the best esti- 
mate that can be formed, amount to about 650 described species, 
a number that will yet, no doubt, be very considerably increased. 
The genera which appear to be peculiar to it are Elites (Saty- 
ridre) ; Zcuxidia (Morphidse) ; Amnosia, Xanthotcmia, and 
Tancccia (Nymphalidae). The groups which are most charac- 
teristic of the region, either from their abundance in individuals 
or species, or from their size and beauty, are — the rich dark- 
coloured Euplcea ; the large semi-transparent Hestia; the plain- 
coloured Mycalms, which replace our meadow-brown butterflies 
(Hipparchia ) ; the curious Elymnias, which often closely resemble 
Euplmas ; the large and handsome Thamantis and Zcuxidia, 
which take the place of the giant Morphos of South America ; 
the Cethosia, of the brightest red, and marked with a curious 
zigzag pattern ; the velvety and blue-glossed Terinos ; the pale 
and delicately-streaked Cyrcstis; the thick-bodied and boldly 
coloured Adolias ; the small wine-coloured Taxila ; the fine blue 
Amblypodia ; the beautiful Thyca , elegantly marked under- 
neath with red and yellow, which represent our common white 
butterflies and are almost equally abundant ; the pale blue 
Eronia , and the large red-tipped IpMas. The genus Papilio 
is represented by a variety of fine groups ; the large Ornithop- 
tcra, with satiny yellow under wings ; the superb green-marked 
broohcana the e< paradoxa ” group, often closely resembling 
the Euplasas that abound in the same district; the " parts ” 
group richly dusted with golden-green specks ; the “ helcnus ” 
group with wide-spreading black and white wings ; the black 
and crimson “ polydorus” group; the “ memnon ” group, of the 
largest size and richly- varied colours ; and the " curypilus ” 
group, elegantly banded or spotted with blue or green : all these 
are so abundant that some of them are met with in every walk, 
and are a constant delight to the naturalist who has the privilege 
of observing them in their native haunts. 
The Coleoptera are far less prominent and require to be care- 
fully sought after; but they then well repay the collector. As 
affording some measure of the productiveness of the tropics in 
insect life it will not be out of place to give a few notes of the
