llostruin slightly arched, rather shorter than the thorax, sub- 

 cyliiidric, just perceptibly narrowed before and behind the middle; 

 finely punctate, rather more closely and coarsely behind, and as far as 

 the back of the rather flat subrotundate eyes. Tliorax rather longer 

 than broad, moderately rounded and widest behind the middle, gradually 

 narrowed towards the apical constriction; moderately coarsely Ijut not 

 closely punctured, more finely and distantly at the apex; with a rather 

 deep impression, Avhicli is broadest at tlie base and nearly reaches the 

 apex, and occupies fully a third of the entire width. Scutellum dis- 

 tinct. Elytra just twice the length of the thorax, a little bi-oader than 

 it is at the base, but not quite as broad there as near the hind thighs, 

 gradually narrowed behind; they are only obsoletely bi-impressed across 

 the disc, but distinctly striate-punctate, the suture is subcarinate and 

 divergent near the extremity; interstices finely rugose but without 

 definite serial punctures, the 3rd somewhat thickened and elevated 

 behind, sharply bent at the extremity and prolonged forwards at tlie 

 sides. 



Legs moderately elongate; penultimate tarsal joints grooved above 

 but not distinctly bilobed. 



Scape medially inserted, Hexuous, very little incrassate at the 

 extremity; 2nd joint of funiculus as long as the basal, 3rd and 4:th 

 very slightly longer than broad, oth shorter, all obconical; club densely 

 pubescent, elongate, nearly as long 'ks joints 2-5 of the funicle. 



Somewhat similar to A. femorajis, 1751, from Mount Egmont, but 

 in tliat species the rostrum and thorax are more finely sculj^tured, the 

 scape is more cui'vate, and the club is shorter. The apical sculpture 

 of the elytra is almost exactly the same in both species; it may, indeed, 

 be considered a generic chai-acter. The ren)arkal)le tlioracic impres- 

 sion distinguishes this species at a glance.

Mount Hutt, near Methven. Found by Mr. T. Hall, at an elevation 

 of 3,500 ft., on the 30th March, 1912. The specimeji is someAvhat muti- 

 lated, and it is probable that better ones will l)e m<^re thickly pubescent. 



3657. Agastegnus rugipennis sp. nov. 



Elongate, rather narrow, slightly convex and nitid; scantily clothed 

 with rather short and slender cinereous setae; piceous, rostrum and 

 antennae, but not tlie cluli, rufous, legs and base of I'lytra pitchy-red, 

 tarsi paler. 



Rostrum i-ather shorter than the thorax, a little arched and parallel 

 in front, feebly dilated at the point of antennal insertion, sliglitly 

 narrowed towards the base; finely and distantly punctate in front, more 

 coarsely and closely behind. Head rather short, its sculpture like that 

 of the rostrum to behind the eyes, more distantly on the middle, and 

 with an elongate impression there; occiput smooth but short. Eyes 

 very slightly convex. Thorax rather longer than broad, its sides only 

 moderately rounded, a little wider behind the middle than elseAvliere, 

 and somewhat contracted at the apex; coarsely but not closely pnnctui-ed, 

 slightly impressed along the middle, the contracted portion moi-e finely 

 punctured, and nearly smooth on the centre. Scutellum distinct. 

 Elytra subcylindric, feebly biarcuate at the base, slightly broader tlian 

 the thorax there, tAvice its length, narroAA'ed near the exti-emity, Avith 

 singly rounded apices, thus forming a slight sutural notch; disc nearly 

 plane, striate-punctate, the striae deeper behind; interstices Avith fine
