We here see in two distant countries a similar relation between plants and insects of the same families, though the species of both are different.

When man is the agent in introducing into a country a new species this relation is often broken: as one instance of this I may mention that the leaves of the cabbages and lettuces, which in England afford food to such a multitude of slugs and caterpillars, in the gardens near Rio are untouched.
During our stay at Brazil I made a large collection of insects.

A few general observations on the comparative importance of the different orders may be interesting to the English entomologist.
The large and brilliantly-coloured Lepidoptera bespeak the zone they inhabit, far more plainly than any other race of animals.

I allude only to the butterflies; for the moths, contrary to what might have been expected from the rankness of the vegetation, certainly appeared in much fewer numbers than in our own temperate regions.

I was much surprised at the habits of Papilio feronia.
This butterfly is not uncommon, and generally frequents the orange-groves.
