and feed on snails, and are found in places frequented by these 

 mollusks, as at the roots of alders and willows, under the bog 

 moss. 



Eurypalpus LeContei is an anomaly, since it lives under stones in 

 rivers and brooks, being oval hemispherical as a larva, the sides of 

 the body greatly extended, resembling some species of Crustacea. 

 The beetles are narrow and rather short. The species of Telephorus 

 live on leaves of plants, especially the birch. They are carnivo- 

 rous, often feeding upon each other. 



We pass by the Malachida^ to the 



Cleridce, which are beetles whose larvae are carnivorous. They 

 are cylindrical, the prothorax narrower than the head. They are 

 fast runners, and run like antS, which they much resemble, over 

 flowers and trees, to feed on the sweets and sap. Trichodes nut- 

 tallii is blue and red, and found on the flowers of Golden rods and 

 Spiraea. The narrow long pink-colored larvae of Thanasimus can 

 be found under the bark of dead pine trees, where it devours the 

 larvae of Hylurgus and Hylobius ; Clerus and allies are found in 

 bumble bees' nests. In Europe they have been found infesting the 

 nests of mason bees ( Osmia and MegacMle.) 



Plinidce. They also infest herbariums and museums. They are 

 small beetles, of an obscure brown color, somewhat oval, behind 

 truncated, the prothorax slender and receiving the head. The an- 

 tennae are long and filiform, and in constant motion when the 

 insect walks. Upon being disturbed it feigns death. They are 

 found about out-houses. Ptinus fur has done great mischief in 

 eating wheat. Anobius is the Death-tick ; the females strike their 

 jaws on the surface of walls, to attract the other sex in the pairing 

 season. The larva are also supposed to make the same noise. 

 Wheh about to change to pupae, they construct silken cocoons. 

 Bostrichus, lives in fungi and under bark ; Cis in toadstools ; the 

 larvae are fleshy white grubs. 



The Tenebrionidce, are apt to be confounded, by beginners, with 

 Carabids, but the prothorax is much narrower than the abdomen, 

 and the head is narrower still. Antennae clavate, feet short, of 

 black or brown colors. The surface is smooth, in Tenebrio, or 

 roughly corrugated in Upis. They are generally found under 

 stones, logs, and in toad-stools. T. moliior, the meal worm, in- 

 habits, granaries. Ship bread is eaten by the larvae, which are 

 " about an inch long, of cylindrical and lineal form, very smooth
