352 DESCRIPTIONS OF NEW SPECIES OP AUSTRALIAN COLEOPTERA, 



serrated, all the joints (after the very small second one) longer than wide, third 

 slightly longer than fourth, eleventh about one-fourth longer than tenth. Pro- 

 thorax almost as long as the apical width, five-areolate, apex obtusely produced 

 in middle, front angles almost rectangular, hind ones produced and acute. 

 Elytra slightly wider near apex than at base; with single rows of large and 

 mostly quadrangular punctures, but becoming double on sides and base. Length, 

 5.5 mm. 



Hah. — New South Wales: Blue Mountains (Dr. E. W. Ferg-uson); unique. 



The dark parts of the type are of a dingy sooty-brown, but probably on 

 fresh specimens would be black; the flavous jiarts of the elytra are slightly 

 dilated on the shoulders and tips, and continued for a short distance on the 

 suture near apex ; the legs and antennae are so thin as to appear semi-trans- 

 parent. The median areolet of the prothorax is narrow at base, of moderate 

 width in middle, and continued almost to apex; an oblique and moderately 

 sharp costa connects it with the middle of each side. The punctures, except 

 close to the base, are in six rows on each elytron, not in live, as is usual when 

 they are in single series, as the lateral row is doubled throughout its length; at 

 the base there are eight rows on each, owing to the humeral thickening pre- 

 venting the doubling of the third and fourth series. The elytral punctures in 

 single series on most of the surface, and the bicoloured and five-areolate pro- 

 thorax, readily distinguish the species from all previously described ones. 



Metriorrhynchus sculpticollis, n. sp. 



c?. Black and brick-red verging to flavous. 



Head with rostruni rather long (about two-thirds the length of prothorax). 

 Antennae rather long and thin, third joint fully thrice as long as wide, fourth 

 about one-third shorter than third, and slightly longer than fifth, the others to 

 tenth gradually decreasing in length but becoming more strongly serrated, 

 eleventh about one-third longer than tenth. Prothorax slightly longer than the 

 apical width; conspicuously seven-areolate ; apex subtriangularly produced but 

 truncated in middle, sides subparallel on apical half, then dilated and elevated to 

 base, with the hind angles rounded off. Elytra almost parallel-sided; with re- 

 gular double rows of punctures, the alternate interstices moderately elevated. 

 Femora with some moderately long hairs; tibiae rather wide. Length, 8-10.5 mm. 



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



The jjale parts are the prothorax, scutellum, elytra, two spots at base of 

 rostrum, and parts of three or four basal joints of antennae; on the type most 

 of the front femora and less of the middle ones are pale, on a second specimen 

 the legs are almost entirely black. Seen from behind the median areolet, at its 

 widest part, appears to have two short costae, connecting it with one which 

 touches the middle of the apex; so that the three form a long-stemmed Y, but 

 from in front the short arms of the Y do not appear to quite touch the marginal 

 costae of the areolet at its widest, consequently, although seven ai-eolets are dis- 

 tinct, the medio-basal one, and two medio-apical ones, do not appear to be com- 

 pletely isolated from each other, although distinctly separated from the lateral 

 ones. Tn general appearance it is close to J/. Hon gat us, M. uniformis, M. tex- 

 tilis, M. nigripes and M. rujirostris, from all of which it is distinguished by the 

 rostrum, this being decidedly longer than in elongatus and rujirostris, and shorter 

 than in the others; its base is also bimaculate. The front of the prothorax is 

 also distinctive: on both specimens the front half of each of the four frontal
