RAKE — BUTTERFLIES.

first named by Mr. Kirby from specimens sent home by Mr. 
Broadway. It is locally known as the Sweet Oil. Both species 
are striped with yellow and black and are often seen flying 
round clumps of bamboos. They appear to mimic the dead yellow 
leaves of the bamboo, and with these leaves as a back ground 
they are often difficult to make out. 
Mechanitis polymnia is another exceedinglycommonand vari- 
able butterfly belonging to this group, and is found in the same 
localities as the two preceding genera. It is about the size of 
Ithomia and has yellow and black markings somewhat like those 
of Tithcrea. 
All this group of Danaince has a pungent odour which 
renders them distasteful to birds. For this reason they are 
mimicked by many other species of butterflies which are without 
this protective smell, and which would otherwise fall easy victims 
to their enemies. 
The next sub-family is that of the Satyrince , well known in 
Europe by its common representatives, the Meadow Brown, Gray- 
ling and Ringlets. In Trinidad it is represented by three genera — 
Euptychia, T ay yetis and Pierella. Eupiychia must be familiar 
to us all from its common example, the little dingy brown butter- 
fly with eyes of various sizes on the under surface of the wings 
which comes down in such numbers to feed on decaying mangoes 
or other fruit. There are many species of Euptychia in Trinidad, 
some of them with a beautiful steel blue sheen on the wings, 
others marked with white, but all of them with eyes on the 
under surface. 
Pay yetis includes the larger dark brown butterflies which 
come out in the dusk and are found flying through shady brush 
wood. One of the commonest species — Taygelis Andromeda — is 
locally known as Night. There are several other species here. 
Of the genus Pierella we have one species — dracontis. It 
is an insect of rare beauty. The fore wings are dingy brown, 
but the hind ones are wonderfully dappled with blue, black and
