preceding ones taken together, and is without an appendage bearing 

 two setfe between the hooks. The Spondyles are also distinguished 

 from the following genera liy their almost globular tliorax, the mar- 

 gin of which is neither recurved nor furnished with teeth or spines. 

 Their larvae live in the interior of the European Pines and Firs. 



S. huprestoide-i ; Attelabm buprestoides, L. ; Oliv. Col. IV, 7I, 

 i, 1. From six to seven lines in length; black; densely punc- 

 tured, with two elevated and longitudinal lines on each elytron. 

 These lines are sometimes obliterated, and the individuals in 

 which this occurs are considered by some entomologists as form- 

 ing a separate species — the elongatam. No others are known*. 



In the third and last genus of this tribe, or 



PmoNcs, Geoff. Fab. Oliv., 

 The antennae are longer than tlie head and thorax, serrated or pec- 

 tinated in some; simple, attenuated near the extremity, and with 

 elongated joints in otliers. The terminal lobe of the maxillae is at 

 least as long as the two first joints of the palpi. The body is gene- 

 rally depressed, and the thorax square or trapezoidal, and cither den- 

 tated or spinous, or angular laterally. 



These Insects only fly towards evening or at night, and always re- 

 main on trees. Certain species, foreign to Europe, are remarkable 

 for their great size, and that of their mandibles. The larva of the 

 P. cervicornif;, which lives in the wood of the Gossampinus, is eaten. 



This genus comprises a considerable number of species, which, 

 from the difference in the form and size of their mandibles, antennae, 

 thorax and abdomen, might constitute several small groups or sub- 

 genera. 



We might, in the first place, separate those species in which the 

 body is straight, elongated, or forms a parallelepiped; the thorax 

 is much shorter than the abdomen, square or trapezoidal, and strongly 

 arcviated laterally; the scutellum is small or moderate ; the antennae 

 are simple or but slightly serrated, and the mandibles frequently 

 large in the males. 



Among the species of this division, with mandibles shorter than 

 the head, the antennae almost setaceous, tolerably long, and composed 

 of eleven joints, the third of which is much longer than the following 

 ones, we find the 



P. scabricornis. Fab. Oliv., Col. IV, 66, XI, 42. Length an 

 inch and a half; antennae bristled with small spines ; a single 

 tooth on each side of the thorax formed by its posterior an- 

 gles f. 

 Other species, generally less oblong and slightly inclined before, 

 in which the mandibles aie always moderate, or project l)ut little in 

 both sexes, with the thorax strongly dentated laterally ; where the
