290 INSECTS. COLEOPTEEA. 



B. Chin of medium size or small, and not covering the base of the jaws. 

 T. Tarsi similar or almost similar in both sexes. 



Gen. SCOTINUS, BLAPS, MTSOLAMPUS, OXURA, SCOTOBIUM, NYCTELIA. 

 2. The two or four anterior tarsi dilated in the males. 



Gen. EURYNOTUS, PEDINUS, PLATYSCELIS. 



Gen. BLAPS, Lat. Tenebrio, Lin. 



Antennae filiform, shorter than the half of the body, with the 

 first joint long, and the last globular ; mouth with two lips ; 

 mandibles scarcely dentated ; jaws bifid, and four palpi ter- 

 minated by a triangular joint ; tarsi of the four anterior 

 feet composed of five joints and the posterior of four ; elytra 

 united. 



These insects in general have no wings. The greater part conceal themselves 

 during the day under stones or in holes, and come out at night to seek their food. 

 They emit a disagreeable odour. The larvae are not known. 



B. mortisaga, Oliv. Lat. Entirely black, smooth,, and somewhat shin- 

 ing; without wings. 12 lines long. Inhabits Europe Lat. 



Hist. x. pi. 88, fig. 3. 



TRIBE III. TENEBRIONITES. 

 With wings, and the elytra free. 



Gen. TENEBRIO, Lin. Fab. Lat. 



Antennae of eleven joints, slightly thickened towards the end, 

 the terminal joint globular, the third elongated ; upper lip 

 apparent ; last joint of the palpi a little thicker than the pre- 

 ceding, conico-cylindrical, compressed ; maxillaries project- 

 ing ; chin almost square. 



The body of the insects of this genus is more or less elongated, glabrous, general^ 

 ly of an obscure colour. They walk quickly and fly well, but rather in the even- 

 ing than in the middle of the day. They are met with in houses, in granaries, kit- 

 chens, and warm or little frequented places, and conceal themselves in the seams of 

 wood and under hangings. The larvae, resembling scaly worms, are about an inch 

 long, with a body of twelve segments, covered by a yellow scaly skin. They eat flour, 

 bread, sugar, &c. and are often used in feeding nightingales. 



T. molitor, Lin. Brown or chestnut-coloured, slightly glabrous, the 

 under parts paler ; thorax square and margined ; elytra striated ; 

 anterior thighs thicker than the others. Inhabits Europe.

The other genera into which this tribe has been divided, and possessing nearly the 

 same general habits, are, 



Gen. CRYPTICCS, EPITRAGUS, OPATRUM, TOXICUM, SARROTRIUM, COR- 

 TICUS, CHIROSCELIS, CALCAR, BOROS, and tins. 



FAMILY II. TAXICORNES. 



Mandibles bifid at the extremity ; joints of the tarsi, except the 

 four anterior, entire ; antennae the length of the head and tho- 

 rax, gradually thickening or terminating in a club, and ge- 

 nerally in part perfoliated. 



The greater part of this family are provided with wings. Their head is ovate,
