By G. R. WateruovssE, Esq. 
[Read 6 December, 1841.] 
Metoron.* Nov. Gen. 
Rostrum elongatum, ad apicem sub-dilatatum. 
Antenn@ tenues, ad basin rostri inserte, 11-articulate, articulis 
3us basalibus subaequalibus, tribus ultimis clavam subsoli- 
dam formantibus. 
Caput latum, pone oculos paulo elongatum ; oculi laterales, ro- 
tundati, prominuli. 
Thorax transversus, basi apiceque truncatus. 
Elytra oblongo-ovata ; humeris subrectangulatis. 
Metopon suturalis, Waterh. (Pl. V. fig. 1 and 1 a, antenna.) 
Met. testaceus; capite, thorace, elytrisque punctatis; scutello 
nigro; elytris ad suturam nigrescentibus. 
Long. corp. (rostr. inclu.) lin, 14. 
Hab. Van Diemen’s Land. 
This insect, I think, should be placed near the following (Minu- 
rus), and the two, it appears to me, might most conveniently be 
arranged between Rhinomacer and Rhynchites. In having the ab- 
domen entirely hidden by the elytra, they agree with the former 
of these two genera, whilst in general form they are intermediate. 
The genus Metopon may be distinguished by the antenne being 
placed at the base of the rostrum. They are more slender than 
in Rhynchites, and in this respect resemble the same organs in 
Minurus, but they are shorter than in that genus, and the joints 
of the club are much less distinctly separated. 
Minvrvs.} Nov. Gen. 
Rostrum elongatum, ad apicem dilatatum. 
Antenne elongate, tenues, versus medium rostri insertz, 11-ar- 
* Mertomov, the forehead, the front, the face, in allusion to the great com- 
parative breadth of the head between the eyes. 
+ Muvugos, little, slender, tiny, &c., in allusion to its small size and more 
slender form, as compared with the allied genus Rhynchites.
