wider than thorax at the base, very gradually and slightly narrowed back- 

 wards, with simple apical margins. 



Legs moderately stout ; tibiae uncinate, the anterior acutely prominent 

 at the inner extremity. Tarsi narrow, their third joint concave in front 

 but entire underneath, unexpanded, the terminal one elongate and slender. 



Prosternum straight in front. Anterior coxae distinctly separated. 

 Metasternum shorter than the abdomen. 



The type of this genus has the aspect of Eutornus, one of the Cossonides, 

 a circumstance which suggested its name. It departs from Pentarthrmn 

 by the much less distant front coxae, by the different rostrum, head, and 

 thorax, as well as by the strongly bent scape and slender terminal joint of 

 the tarsi, and, moreover, the female in Pentarthrmn is strongly differen- 

 tiated from the male by her slender rostrum, differently shaped thorax, 

 and different antennal insertion, whereas Eutornopsis presents no very 

 obvious sexual characteristics. 



Eutornopsis piceus, sp. nov. 



Piceous, moderately shining, with a rufescent mark behind each 

 shoulder, antennae and legs piceo-rufous ; the club and inner face of the 

 front tibiae bear yellow pubescence. 



Rostrum distinctly and moderately coarsely punctured, its apical por- 

 tion and the head more finely and distantly, the occiput smooth behind. 

 Thorax broadest near the base but not very evidently dilated or rounded 

 there ; its punctation moderately coarse and close, but much finer in 

 front. Elytra punctate-striate, the 2nd and 3rd striae deepest near the 

 extremity, the outer striae indistinct, the punctiu'es are somewhat trans- 

 versal and distinctly separated from each other ; interstices with fine dis- 

 tant serial punctures. 



Underside shining, piceous, rather finely, not closely, and somewhat 

 irregularly punctured, the basal ventral segment more closely than the 

 metasternum, the 3rd, 4th, and 5th segments with deep sutures, 5th closely 

 punctate and slightly impressed across the middle, the metasternum and 

 basal 2 segments shghtly flattened but not concave. The pubescence 

 yellow and scanty. The rostrum has almost seriate punctures, but along 

 each side of the middle there is an elongated smooth space. 



Female : Rather larger, her rostrum very slightly longer and more finely 

 punctate. 



Length, 2^2f Knes ; breadth, quite ^ hne. 



Sunday Island. 



Several specimens found by Mr. W. L. Wallace amongst decaying ngaio 

 and karaka. 



Microtribus sculpturatus, sp. nov. 



Fusiform, sparingly clothed with very fine suberect grey hairs ; mode- 

 rately shining, piceous, apical margin of thorax slightly rufescent, antennae 

 and legs piceo-rufous. 



Rostrum of about the same length as the thorax, moderately stout, 

 slightly arched, parallel ; distinctly, moderately finely but not closely 

 punctured, more indistinctly in front, where there are some fine yellowish 

 setae. Head rather more distantly and finely punctate. Thorax longer 

 than broad, its sides hardly at all rounded ; rather closely and coarsely 

 punctured, the intervals densely and minutely sculptured. Scutellum 

 absent. Elytra elongate, subovate, sUghtly wider than thorax at the
