We have rather a large number of families, many with a few species only, and as a whole they are feeders in or on decaying or dry vegetable tissue, whether herbaceous, woody, or fungoid in character. There are exceptions, of course, but that is the rule. The Tencbrionidce, or "; contain species ranging from quite small to very large, found under all sorts of conditions, but most frequently beneath bark of trees, on fungi, or under stones, among dry vegetable matter. There is no uniformity in appearance, but in most instances the antennae are more or less moniliform, or bead-like. The majority of our species are Western, occurring in their greatest variety in the Rocky Mountain region, but none, so far as I know, trouble green vegetation. The typical genus Tenebrio contains black or brownish, somewhat flattened species, with a square thorax and deeply ridged wing-covers. The larvae are known as " meal-worms," and feed upon grain or meal remnants in barn, stable, or other sheltered
