The poor cottagers in vain attempted by lighting fires, by shouts, and by waving branches, to avert the attack.

This species of locust closely resembles, and perhaps is identical with, the famous Gryllus migratorius of the East.
We crossed the Luxan, which is a river of considerable size, though its course towards the sea-coast is very imperfectly known: it is even doubtful whether, in passing over the plains, it is not evaporated and lost.

We slept in the village of Luxan, which is a small place surrounded by gardens, and forms the most southern cultivated district in the Province of Mendoza; it is five leagues south of the capital.

At night I experienced an attack (for it deserves no less a name) of the Benchuca, a species of Reduvius, the great black bug of the Pampas.

It is most disgusting to feel soft wingless insects, about an inch long, crawling over one's body.
