the declivity, the 5th do not extend as far back as the 3rd but behind form the 

 thick sides of the dorsum ; when brushed with benzene some coppery-red 

 scales are seen on the suture near the base -their natural colour, no doubt. 



Scape finely setose, very gradually thickened, attaining the back of the 

 eye ; 2nd joint of funiculus elongate, yet hardly perceptibly longer than the 

 basal, 3rd rather longer than 4th, and, like it, obconical ; club opaque, 

 minutely and densely pubescent, elongate-oval and triarticulate. 



Legs with fuscous and greyish scales and setae, tibiae flexuous, the 

 anterior not distinctly mucronate, posterior corbels with duplicate external 

 cilia and narrow intervals. 



Underside piceous, with dull-tawny scales and moderately elongate grey 

 setae. Prosternum deeply emarginate. Metasternum slioit. Basal ventral 

 segment truncate between the coxae and somewhat depressed there, medi- 

 ally incui'ved behind, yet, in the middle, rather longer than the 2nd, 5th 

 broadly depressed along the centre. 



Shorter and relatively broader" than the female of /. pensus, 3600, from 

 the same locality, the elytra with a gentle downward slope towards the top 

 of the hind declivity, as broad there as at the shoulders and without any 

 apical prolongation. The form of the hind-body, with the 5th instead of 

 the 7th interstices forming the raised sides at the commencement of the 

 apical declivity, in conjunction with the absence of the common rostral 

 carinae distinguish this from all the other species of this complex genus. 



$. Length (rostrum inclusive), 8i mm. ; breadth, 3o mm. 



Male. — Body and legs concolorous, pale tawny-brown, antennae piceo- 

 rufous. Rostrum slightly shorter, broadly convex along the middle. Elytra 

 narrower, with less rounded shoulders, apices not prominent but strongly 

 rounded singly and slightly dehiscent. Anterior tibiae more evidently 

 mucronate. Basal ventral segment less sinuate behind, rather flatter, 5th 

 as long as preceding two together, rounded behind, with suberect yellow 

 seta. 71 mm. by 2J mm. 



Mount Hutt. One of each sex found on 25th January, 1913, at an 

 altitude of 4,.5()0 ft., by Mr. T. Hall. The male a little immature. 



3758. Inophloeus tricostatus sp. nov. 



Subopaque, nigrescent, antennae fusco-rufous, tarsi rufo-piceous ; head, 

 rostrum, and front of thorax with a few depressed, quite grey squamae ; 

 elytra with only a few, the legs with numerous rather fine setae. 



Rostrum a third shorter than thorax, irregularly and rather finely punc- 

 tate, broadly bisulcate, and distinctly tricarinate almost as far as the inter- 

 ocular fovea. Thorax of equal length and breadth, widest and moderately 

 rounded at or just before the middle, gradually narrowed behind ; without 

 inequalities, veiy irregularly and finely punctui'ed, rugose at the sides. 

 Scutellum small. Elytra oblong, thrice the length of thorax, gently narrowed 

 near the base and slightly broadei' there than the thorax, posterior declivity 

 vertical and considerably narrowed, with prolonged apices ; dorsum slightly 

 convex, with regular series of moderately large well-marked punctures, the 

 suture plane, only slightly and quite horizontally prominent on top of the 

 declivity ; 3rd, 5th, and 7th interstices costate, the first of these slightly, 

 the next not at all elevated behind, the 7th moderately distinct near the 

 middle, obsolete elsewhere. 



Antennae I'ather slender, scape attaining back of eye ; 2nd joint of funi- 

 culus as long as the 1st, both elongate, 3rd shorter, but evidently longer 

 than following ones ; club verv elongate oval.
