192 Mr. G. R. Waterhouse’s Description of 
Order COLEOPTERA. 
Section Rhyncophora. 
Genus Belus, Schonh. 
Belus testaceus. 
B ■ ater ; supra crebre punctatus ; tliorace, elytris, pedibusque 
testaceis ; tarsis nigris, rostro gracile, subelongato at leviter 
curvato ; capite fere thoracem longitudine, equante ; tliorace 
brevi, sulco dorsali obscure impresso, cylindraceo ■, elytris 
linearibus elongatis, latitudinem thoracis aequantibus, et ad 
apicem cuspidatis. 
Long. corp. 4 lin. 
Hab. in Australasia. 
Obs. — This species, which was found near King George’s 
Sound, appears to have all the principal characters of the genus 
to which I have referred it. The antennae, if bent backwards, 
would extend considerably beyond the base of the thorax ; they 
have the six basal joints long and slender, and the five following 
incrassated ; the terminal joint is rather longer than the preceding, 
and pointed at the apex. The eyes are large. The head and 
thorax are very thickly punctured, the punctures are confluent; 
there is a shallow fovea on the former between the eyes, and the 
latter has an indistinct dorsal channel. The elytra are also very 
thickly punctured, the punctures are confluent, and have an ob- 
scure indication of being arranged in longitudinal striae. The 
four posterior femora are pitchy-red, and the apex of the anterior 
tibiae is blackish. 
CuRCULIONIDiE. 
Leptosomus acuminatus, L. (Plate XVII. fig. 2.) 
This insect is described by Fabricius ( Syst . El. 2, p. 535,) 
under the name of Curculio acuminatus, and, according to Schon- 
lierr, it constitutes the genus Leptosomus. 
The latter author, however, appears not to have had an oppor- 
tunity of examining the insect, since he quotes its characters from 
another work. As it is a very interesting genus, and some of its 
characters appear not to be known, perhaps I may be excused for 
adding those characters. 
As regards the genus, the additional characters are as follows : 
Antennae inserted near the apex of the rostrum : funiculus about 
equal in length to the scapus, seven-jointed ; the first coarctate, 
longer than broad ; the five following equal, rather short ; the 
seventh subobconic ; club indistinctly three-jointed, ovate, acu- 
minate. (PI. XVII. fig. 2 a.)
