Head with very short rostrum. Antennae with long 

 rami. Protliorax moderately transverse; conspicuously seven- 

 areolate; apex obtusely produced in middle, sides narrowed 

 to middle, front angles obtuse, hind ones produced and acute, 

 median areolet large, produced fairly close to apex. Elytra 

 rather thin and parallel-sided; with double rows of regular 

 punctures to near apex, the alternate interstices moderately 

 elevated, but the same as the others on the dark portion. 

 Length, 7-9 mm. 



Hab. — Northern Territory: Darwin and Daly River (H. 

 Wesselman). Type, I. 11828.' 



The ramus on the third joint of the antennae is about 

 twice the length of its supporting portion, on the following 

 ones, to tenth, it is longer (up to thrice the length of its 

 support), the eleventh joint is about thrice the length of the 

 non-ramose portion of the tenth ; the lengths of the rami, 

 however, vary slightly on the six specimens taken. In my 

 table the species would be placed with M. posticalis, M. 

 gracilis, and M. fallax ; of these gracilis was described as 

 having more of the under-surface and legs dark, and less of 

 the elytra, and with very different prothoracic areolets, on 

 the present species they are all well defined, and the central 

 one is not confined to the basal half ; posticalis has more of 

 elytra and of under-surface dark, and the areolets different; 

 fallax (of which I only know the females) has less of elytra 

 and more of under-surface dark, and the areolets different. 



Metriorrhynchus trichocerus, n. sp. 



d • Flavous; head, antennae, palpi, apical third (or 

 more) of elytra, abdomen, tarsi, and parts of tibiae black. 



Head with rostrum very short. Antennae with long 

 rami on third to tenth joints, the rami with moderately dense 

 and rather long hairs, eleventh joint more than twice the 

 length of the non-ramose part of tenth. Protliorax moderately 

 transverse ; conspicuously seven-areolate, apex obtusely pro- 

 duced, sides narrowed to middle; front angles obtuse, hind 

 ones slightly produced and subacute, central areolet slightly 

 produced between bases of medio-apical ones. Elytra thin 

 and parallel-sided; with regular double rows of punctures, 

 the alternate interstices moderately elevated. Length, 

 6-7*5 mm. 



Hab. — Northern Territory: Melville Island (W. D. 

 Dodd). Type, I. 11820. 



All the rami are long, the shortest (on the third joint) 

 being almost twice as long as its support. The species is 

 allied to the preceding one, but the rami have conspicuous 

 clothing, the abdomen is dark, and the metasternum pale
