An elliptic species with the oiitliues of prothorax and' 

 elytra continuous. The prothorax is narrower than in semi- 

 porosus, its punctures rather denser, and conspicuously dif- 

 ferent in size at base and apex, and elytral interstices more 

 convex. In general appearance close to riiflmaniis, but punc- 

 tures of second abdominal segment distinctly larger, and third 

 and fourth each with a conspicuous row; the teeth of the 

 front femora also are no larger (if as large) as those of the 

 middle pair, wdiereas on that species they are distinctly larger. 

 In this, as in many other species of the genus, the seriate 

 punctures on the elytra, although rather large, are not sharply 

 defined, and appear more as dilated portions of the striae 

 rather than as isolated punctures. 



Melantzrius mediocris, n. sp. 



Blackish-brown ; antennae and claw joint of a dingy-red. 

 Elytra with a row of minute setae on each side of each inter- 

 stice ; under-surface and legs with distinct white setae. 



Eyes close together. Rostrum rather long and thin ; with 

 dense punctures, becoming linear in arrangement behind 

 antennae. Scape inserted about three-sevenths from apex of 

 rostrum, distinctly shorter than funicle; first joint of funicle 

 longer than second. Proihorax moderately transverse, sides 

 strongly rounded ; punctures much as on preceding species. 

 Elytra cordate, shoulders and sides strongly rounded; with 

 series of large somewhat distant punctures, becoming smaller 

 posteriorly; interstices acutely carinated, but not to extreme 

 base, the sutural one only posteriorly, the next three rather 

 feebly on basal third; each with a somewhat irregular row 

 of small punctures on each side of each ridge. Metasternum 

 and basal segment of abdomen, and part of second segment, 

 with dense and rather coarse punctures; basal segment gently 

 convex in middle. Femora stout, strongly dentate, and each 

 with a granule in emargination. Length, 5 mm. 



Hah. — Queensland: Cairns (E. Allen). 



In general appearance somewhat close to strahonis, but 

 larger, second interstice not quite the same and femoral denti- 

 tion less strong. Also close to confiisus, but suture and denti- 

 tion different. Also like large specimens of 2)"rsimilis, but the 

 interstices differently granulate; in that species the inter- 

 stices have, on their outer sides, a granule placed at about 

 the middle of the side of each of the large seriate punctures 

 or foveae, but there are no granules on the inner sides of the 

 interstices. On the present species there are granules on both 

 sides. On the preceding species there are a few granules on 

 the outer sides of the interstices, but their places are usually 

 marked by slight median extensions of the foveae. The elytra,.
