ORDER COLEOPTERA. 499 



tongue very distinct ; the labrum elongated ; the two ante- 

 rior legs widened, and presenting in the males a pallette- 

 formed spur like a reversed triangle, and a sternal point.* 



Two other sub-genera, established by Mr. W. Macleay, 

 approach lamprima, in consequence of their mesosternutn 

 which is prolonged and advanced, but less, however, than in 

 the preceding ; of their head, much more narrow than the 

 corslet, and their mandibles furnished with down at the in- 

 ternal side; but their body is flatted or but little raised, 

 especially in the females. The labrum is concealed. The 

 anterior legs are strait and without palette. The palpi and 

 the lobes of the tong-ue are more elongated.

Ryssonotus, 



In which the mandibles of the males form, as in Lamprima, 

 pincers vertically compressed, angular, and denticulated.-|- 



Pholidotus, Macl. Chalcimon, Dalm. Lamprima, 

 Schoenh., 



In which the mandibles in the same sex are very long, nar- 

 row, arched, terminated in a hook curved inferiorly, and 

 denticulated like a saw at the internal side. 



The knob of the antennae, formed by the last three articu- 

 culations, is less pectinated than in the others, and almost 

 perfoliate. The chin covers the jaws.:|:
