Metriorrhynchus funestus, n. sp. 



<3 . Sooty-black. 



Head with very short rostrum. Antennae rather long, 

 third to tenth joints ramose, eleventh more than twice the 

 length of the non-ramose portion of tenth. Prothorax 

 moderately transverse; conspicuously seven-areolate ; front 

 angles slightly obtuse, hind ones produced and acute, sides 

 almost parallel to near base. Elytra parallel-sided; with 

 somewhat irregular double rows of punctures, the alternate 

 interstices distinctly elevated. Length, 5 "5 -6 '5 mm. 



Rah. — Queensland: Cairns district (A. M. Lea). Type, 

 I. 11825. 



Readily distinguished from all' previously named black 

 species by the long antennal rami; M. opacus, of which only 

 the female is known, has very different prothorax ; the ramus 

 of the third joint commences near the middle of the inner 

 side, on the others it is gradually advanced till on the tenth 

 it commences near the tip, on the third and tenth joints it 

 is almost twice the length of the supporting portion, on each 

 of the intervening joints it is more than twice the length of 

 its supporting portion. Of the median areolets of the 

 23rothorax the front ones are about ^wo-thirds the length 

 of the hind one. The short costae dividing off the elytral 

 punctures are often transversely Y-shaped, and from some 

 directions the rows in places appear to be in single instead 

 of double series ; but when the elytra are so placed that the 

 thinner parts appear semi transparent, the punctures appear 

 to be in quite regular double rows. 



Metriorrhynchus rufomarginatus, n. sp. 



6* . Black; tips of elytra, each lateral costa, and part of 

 suture bright red. 



Head with rostrum very short. Antennae moderately 

 long, third to tenth joints strongly serrated or subpectinated. 

 Prothorax moderately transverse, apex obtusely produced in 

 middle, sides moderately dilated and rather strongly elevated 

 from middle^ to base, front angles obtuse, hind ones (except 

 for a slight rounding off) almost square ; conspicuously seven- 

 areolate, the median areolet produced in front to about the 

 middle of the medio-frontal areolets. Tips of scutellum 

 produced. Elytra slightly dilated posteriorly; with irregular 

 double series of large punctures, alternate interstices slightly 

 elevated. Length (d, 9), 13-17 mm. 



9 • Differs in having the antennae shorter and less 

 strongly serrated (not subpectinated), abdomen wider, the 

 subapical segment not notched, and legs slightly shorter.
