They are small, black, oval, heteromerous beetles, in which the anterior coxal cavities are open behind ; and in which the antennae are received in grooves on the under side of the prothorax. The family MELANDRYlDiE (Mel-an-dry'i-dae) includes about sixty North American species. These are found under bark and in fungi. They are usually of elongate form, al- though some, like the one figured here, are not so. The maxillary palpi are frequently very long and much dilated ; and the first segment of the hind tarsi is always much elongated. Among our more common species are two belonging to the genus Penthe (Pen'the). These are rather large, oval, de- pressed beetles, upwards of half an inch in length, and of a deep black color. Penthe obli- Fig. 714. qjiata (P. ob-li-qua'ta) is distinguished by having the scutel- lum clothed with rust-red hairs (Fig. 714). PentJiepimelia (P. pi meri-a) closely resembles this species, except that the scutellum is black. The family Pythid^ (Pyth'i-dae) includes less than a score of North American species. Some of these live under bark; others are found under stones. They are heteromer- ous beetles, in which the anterior coxal cavities are open behind, the head is not strongly and suddenly constricted at base, and the prothorax is not margined at the sides. The family CEDEMERlDiE (GEd-e-mer'i-dse) is composed of heteromerous beetles of moderate size, with elongate, narrow bodies. The head and prothorax are somewhat nar- rower than the wing-covers; the antennae are long, nearly filiform, sometimes serrate; the anterior coxal cavities are open behind, and the middle coxae are very prominent. Less than fifty North American species have been de- scribed. They are generally found on plants, but some live on the ground near water. The family Cephaloid^ (Ceph-a-lo'i-dse) includes only a single genus, which is represented in this country by but. Please note that these images ar
