large, particularly in most of the males; the internal lobe of 

 the maxilloB null or very small ; the antennae inserted near the 

 base of the mandibles or the einargination of the eyes, but 

 not surrounded by the latter at base ; the thorax most fre- 

 quently trapezoidal or square, crenated or dentated laterally. 

 The first genus, or 



Parandra, Lat. — AUelabus^ De Geer, — Tenebrio, .Fab., 



Where, asin the following, the antennae are simple, almost granose, 

 compressed, of equal thickness throughout, and as long as the tho- 

 rax at most, and the terminal lobe. of the maxillse is very small, 

 scarcely reaching to the extremity of the first joint of the palpi, is 

 distinguished from that genus(l), as well as from all others of the 

 same family, by its corneous ligula, which is in the form of the seg- 

 ment of a very short, transversal circle without emargination or 

 lobes, and by its tarsi, the penultimate joint of which is slightly 

 bilobate, and the last, much longer than the preceding ones taken 

 together, presents between its hooks a little appendage with two 

 terminal setse. The body is a parallelopiped, and depressed, and the 

 thorax square, rounded at the posterior angles, and without spines 

 or teeth. 



These Insects are peculiar to America(2). 



Spondylis, Fab. — tdttelabus, Lin. — CeramhyXj De Geer. 



The Spondyles, which approximate to the Parandrae in their antennae 

 and the exiguity of their maxillary lobes, are removed from them by 

 their ligula; the latter, as in all the following Longicornes, is mem- 

 branous and cordiform. They also differ in the tarsi; the penulti- 

 mate joint is deeply bilobate, and the last is not longer than the pre- 

 ceding ones taken together, and is without an appendage bearing 

 two setse between the hooks. The Spondyles are also distinguished 

 from the following genera by their almost globular thorax, 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.

 head, triangidar or conical and arcuated at tlie end.
