Group MOLYTIDiE. 



Lyperobius laeviusculus, sp. nov. 



Pitchy-black, sometimes rufo-piceous; hind-body sparingly 

 clothed with depressed, testaceous, setiform scales. Bostrum 

 nearly plane above, medially narrowed, rather finely 

 punctured. Head broader than the rostrum, with a shallow 

 median groove before the eyes and some transversal linear 

 impressions behind. Eyes more rotundate than those of the 

 typical species. Scrobes deep in front, but quite indefinite 

 behind. Scape thickened apically, attaining the back of the 

 eye. Funiculus sparsely pilose, second joint only slightly 

 shorter than the first ; joints 3-7 moniliform. Club Particu- 

 late, rather elongate, finely pubescent. Thorax somewhat un- 

 even, without central carina, finely punctate. Elytra oblong- 

 oval, humeral angles narrowed and rounded, rather acuminate 

 posteriorly ; each elytron indistinctly tricostate, suture 

 slightly elevated, interstices nearly smooth, with only feebly 

 impressed series of punctures. Legs rather elongate ; femora 

 clavate ; tibiae flexuous, without the usual inner armature just 

 above the extremity ; the anterior pair with pale erect setae 

 along the inside. Underside nearly smooth, almost nude. 

 Presternum a little emarginate. Length (rost. included), 

 10-12 lines ; breadth, 3^—5 lines. 



Auckland Islands. Captain Bollans, of the Government 

 steamer " Hinemoa," found two specimens on Adam's Island. 

 The larger one has very indefinite elytral costae. One speci- 

 men retained in Captain Broun's collection, the other placed 

 in the Canterbury Museum.

 Wings pointed ; two simple veins between the forked 

 veins, the second of these two ending at or before the apex. 

 Proboscis compressed, the maxillae nearly as long.
