But the faculty of becoming torpid at such periods is not confined in Ceylon to the crocodile sand fishes; it is also possessed by some of the fresh-water mollusca and aquatic coleoptera. One of the former, the Ampullaria glauca, is found in still water in all parts of the island, not alone in the tanks, but in rice-fields and the watercourses by which they are irrigated.

Nicolet, the naturalist who, previous to Lubbock, has given us the most correct and complete account of the Thysanura, regarded them as an order, equivalent to the Coleoptera or Diptera, for example. In this he followed Latreille, who established the order in 1796. The Abbé Bourlet adopted the same view.
It is one of the most remarkable cases of mimicry, since the beetle has the thorax and body densely hairy like the bee, and the legs are tufted in a manner most unusual in the order Coleoptera. Another Longicorn, Odontocera odyneroides, has the abdomen banded with yellow, and constricted at the base, and is altogether so exactly like a small common wasp of the genus Odynerus, that Mr.
The art of domesticating the Claviger is a stage of civilisation reached by some tribes and not by others. Lespès has placed this out of doubt in the following manner. He had specimens of Lasius niger who exploited a flock of Coleoptera. Having met ants of the same species who possessed no flocks, he brought them some.
The Lanius collurio, an allied bird, uses this method still more frequently. He even prepares a small larder before feasting. One may thus see on a thorny branch spitted side by side Coleoptera, crickets, grasshoppers, frogs, and even young birds, which he has seized when they were in flight. Naumann, Naturgeschichte der Vögel Deutschlands, etc., Stuttgart, 1846-53.
These are large Coleoptera who feed on abandoned carrion; everything is good to them bodies of small mammals, birds, or frogs; they are very easy to please, and as long as the beast is dead that is all they require. When they have found such remains, and consider only how to satisfy their hunger, they do not take much trouble, and gnaw the prey on the spot where they have found it.
Even this perfectly gradual transition from the youngest larva to the sexually mature Insect, preserves in a far higher degree the picture of an original mode of development, than does the so-called complete metamorphosis of the Coleoptera, Lepidoptera, or Diptera, with its abruptly separated larva-, pupa- and imago-states.
In all the orders, the scarcity of the individuals is even more remarkable than that of the species. Most of the Coleoptera have been carefully described by Mr. Waterhouse in the Annals of Nat. Hist. Hooker tells me, it extends to the R. San Francisco in California, and perhaps even to Kamtschatka.
From the analogy of the Orthoptera and Homoptera, I expected to find the stridulating organs in the Coleoptera differing according to sex; but Landois, who has carefully examined several species, observed no such difference; nor did Westring; nor did Mr. G.R. Crotch in preparing the many specimens which he had the kindness to send me.
