distinctly longer than fourth, the others feebly decreasing in length. Prothorax 
moderately transverse, sides almost evenly increasing in width to base, hind angles 
acute ; regularly seven -areo late. Elytra thin, parallel-sided ; with regular double 
rows of punctures, the alternate interstices distinctly elevated. Length, 10 mm. 
Queensland : Cairns district (F. P. Dodd). Type (unique), in South 
Australian Museum. 
The rostrum is decidedly longer and thinner than on M. nigripes, textilis, 
uni for mis, ramicornis , and sculp ticollis, being much as on many specimens of 
M. rhipidius, and slightly longer than the prothorax. 
Metriorrhynchus decipiens n. sp. 
Black, sides of prothorax and most of elytra reddish testaceous. 
Rostrum moderately long, but, excluding the lips, not quite as long as wide ; 
antennae moderately long, strongly serrated or subpectinated, third joint distinctly 
longer than fourth and slightly longer than eleventh. Prothorax moderately 
transverse, sides dilated and elevated to base, regularly seven- areolate. Elytra 
narrow, parallel-sided to near apex ; with regular double rows of transverse or 
subquadrate punctures, alternate interstices moderately elevated. Abdomen deeply 
notched. Length, 11-12 mm. 
$. Differs in having antennae somewhat shorter and less strongly serrated 
and abdomen not notched. 
Queensland : National Park in December. New South Wales : Tooloom 
in January (H. Hacker). Type, in Queensland Museum ; cotype, in South Australian 
Museum . 
The rostrum is not quite as long as on M. variipennis , and the sides of the 
prothorax are more evenly dilated to the base. Less of the elytra are black than 
on M. ordinarius, and the rostrum is distinctly shorter. At first glance the species 
appears to belong to M. medioniger , but the prothorax has the sides more dilated 
to the base and the rostrum is distinctly longer ; that species belongs to a section 
of the genus in which the rostrum is very short or absent. The moderately long 
rostrum is much as on M . irregularis , but the size is larger and the elytra are partly 
black. About the median half of the pro thorax is black, on the elytra the black 
part extends across three rows of puncture on each side of the suture at the base, 
but is narrowed and terminates at the basal third. The tips of the abdominal 
segments are very narrowly pale, but the pale parts could be easily overlooked. 
The specimen from Tooloom has the black part of the elytra extending almost 
across the entire base, and continued to well beyond the middle, but with the black 
part of the ridges terminated before that of the depressed parts. 
Metriorrhynchus per tenuis n. sp. 
(J. Blackish, sides and apex of prothorax, elytra, base of front and of middle 
femora and the coxse flavo-testaceous. 
Rostrum moderately long, including the lips slightly longer than wide. 
Antennse rather long and strongly serrated, third joint slightly longer than fourth, 
the eleventh very little longer than tenth. Prothorax about as long as the basal 
width , which is decidedly more than that of apex, sides almost parallel on apical 
half, triangularly dilated posteriorly ; regularly seven -areolate. Elytra very narrow ;
