black/ head wider than the bodyj wings reddish. Its ova are 

 remarkably large. Very common in the environs of Paris, un- 

 der stones. 



S. maxillosus, L. ; Panz. ib. 2. About eight lines in lenglhj 

 black; glossy; head wider than the thorax; great part of the 

 abdomen and elytra cinereous grey, dotted and spotted with 

 black. In earth, dung, &c. 



S. murinus, Fab.; Panz., ib., LXVI, 16. From four to six 

 lines long; head, thorax and elytra deep bronze, glossy, with 

 dusky spots; scutel yellowish, marked with two atrous spots; 

 abdomen black; greater part of the antennze reddish. Found

S. trythropterus, L.; Panz., XXVIII, 4. From six to ten 

 lines in length; black; elytra, base of the antennae and legs ful-

 ■ The others, which are linear, with a head and thorax elongated in 

 the form of a long square, have their antennae approximated at base, 

 and strongly geniculate and granose; their anterior tarsi are usually 

 not at all or but very slightly dilated. The anterior tibiae are spin- 

 ous, with a stout spine at the extremity. The labrum is small. 

 They form the genus Xantholinus of some entomologists(2). 



PiNOPHiLus, Grav. 



Palpi filiform; but the antennae inserted before the eyes, outside of 

 the labrum, and near the exterior base of the mandibles(3). 



Lathkobium, Grav. — Paederus, Fab. 



Palpi suddenly terminated by a pointed and frequently indistinct 

 joint, much smaller than the penultimate; those of the maxillae 

 much longer than the labials; the antennae inserted as in Pinophilus; 

 anterior tarsi strongly dilated in both sexes; length of the last joint 

 of the four posterior tarsi almost equal to that of the four preceding
