COLEOPTEBA.—LEA. 195 



as long, the species would be associated with M. ahdominalis. whose male has 

 very different hind tibiae ; regarding it as short, with M. fallax, whose rostrum 

 is distinctly shorter, legs darker and less of elytra black; at first glance it 

 resembles M. apicalis, M. ahdominalis, and M. mclaspis; it is, however, distinct 

 from all species of the genus, except 31. tihialis, by the peculiar hind tibiss ; from 

 tibialis itself it is distinct by the larger size, longer rostrum (about twice its 

 length), longer antennae (of different colour, clothing, and proportions), prothorax 

 and scutellura entirely pale, and more of legs and of elytra pale ; the dark part 

 of the elytra is narrowest at the suture, instead of widest there; the projection 

 itself is also somewhat different from that of tibudis — it can be partially received 

 into an excavation near the base of the hind femora. The outer walls of the 

 latero-posterior areolets are considerably higher than the others. 



METRIORRHYNCHUS FLAVIPENNIS sp nov. 

 ^ Black, elytra fiavous. 



Head Avithout distinct rostrum. Antenme rather long, third to tenth joints 

 feebly serrated (eleventh missing)', third slightly longer than fourth, the 

 following ones gradually decreasing in width, but not in length. Prothorax 

 moderately transverse ; conspicuously seven-areolate ; apex slightly produced in 

 middle, sides dilated from middle to base, front angles obtuse, hind ones produced 

 and acute. Scutellum with tips produced. Elytra thin, almost parallel-sided; 

 each with ten regular rows of punctures, becoming irregular at base and tips. 

 Length, 7 mm.

 (unique), C/3286 in Queen.sland Museum. 



A narrow species, at first glance apparentlj- belonging to one of the forms 

 of M. rufipennis, with which it would be associated in my table, but the 

 antennae very feebly serrated (much less strongly than even on the female of 

 that species), and punctures, owing to the non-elevation of the alternate inter- 

 stices, in ten regular rows on each elytron, instead of in five double rows. 



METRIORRHYNCHUS MEDIONIGER sp. ncv. 



(J Black, sides of prothorax and most of elytra brick-red. 



Head with rostrum very short. Antennic moderately long, rather wide 

 and rather strongly serrated, but without a tendency to pectination. Prothorax 

 about as long as wide ; conspicuously seven-areolate ; apex obtu.sely produced in 

 middle, sides feebly dilated to base, front angles widely rounded oft", hind ones 

 almost rectangular. Elytra feebly dilated posteriorly; with regular double rows 

 of punctures, the alternate interstices elevated. Length ( c?$ ), 8-10 mm. 



9 Differs in having antennae somewhat shorter and slightly less serrated, 

 abdomen wider, subapical segment not notched, and legs somewhat shorter.
