COLEOPTERA. 415 



STAPHTLINUS, fab. 



Or the true Staphylini, all the palpi are filiform, and the antennae 

 are inserted between the eyes, above the labrum and mandibles. 



Some, particularly the males, have the anterior tarsi greatly dilated, 

 and the antennae separated at base ; the length of the first joint of the 

 latter is equal, at most, to that of a fourth of the whole number. 

 The head is but slightly elongated. In some systems, those species 

 alone which present the above characters, constitute the genus Staphy- 

 linus. The 5. dilatatus^ Fab., Germ., Faun. Insect. Europ., VI, 14, 

 has even been separated from it, to compose another, on account of 

 its antennae, which form an elongated serrated club. According to 

 the observations of M. Chevrolat, a zealous entomologist, this Insect 

 feeds on caterpillars which it searches for on trees. 



S. hirtus, L. ; Panz., Faun. Insect. Germ., IV, 19. Ten lines 

 in length ; black ; very hairy ; superior surface of the head, 

 thorax, and last abdominal annuli covered with thick hairs of a 

 glossy golden-yellow ; elytra cinereous-grey, with a black base ; 

 under part of the body bluish-black. North of Europe, France, 

 and Germany. 



S. olens, Fab., Panz. ib., XXVII, 1. An inch long; dead 

 black ; head wider than the body ; wings reddish. Its ova are 

 remarkably large. Very common in the environs of Paris, 

 under stones. 



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

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

 abdomen and elytra cinereous grey, dotted and spotted with 

 black. Inearth, dung, &c. 



S. murinuSj 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 antennae reddish. Found 

 with the preceding, 



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

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

 fulvous *. 



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 Xanth olinus of some entomologists f .
