280 COLEOPTERA 



behind ; front and middle coxa sub-globose ; the posterior lamelliform. 

 canaliculate behind ; tibia linear, their spurs very small or indistinct ; 

 tarsi five-jointed, often provided with lamellae underneath. Abdomen com- 

 posed of five distinct segments. Prosternum (among the greater 

 number) provided with a chin-piece in front ; its posterior projection 

 variable, compressed, capable of free motion. 



'Thoramus. 



Sharp ; Ann. Mag. Nat Hist., May, 1877. 



Forehead quite straight in front, slightly overhanging the perpen- 

 dicular clypeus, so that a very distinct step exists between the forehead 

 and the labrum ; antennal spaces very small, broadly separated ; antenna 

 with joints two and three but little developed, four to ten always at least 

 serrate internally, sometimes with anterior internal angle much pro- 

 longed, eleventh joint with a more or less distinct terminal appendage 

 or false joint. Mesosternal cavity and its suture with the metasternum 

 variable. Tarsi simple and linear, the fourth joint rather long, though 

 a good deal shorter than any of the others ; coxal plate of hind coxa 

 well developed throughout, its trochanteral portion quite twice as long 

 as its femoral. Elytra not acuminate. Species of large size. 



489. T. wakeneldi, Sharp ; Ann. Mag. Nat. Hist., May, 1877. 

 T. niger, sat nitidus, breviter et sequaliter fusco-pubescens ; prothorace 

 crebre punctato, angulis posterioribus divergentibus ; elytris subtiliter 

 striatis, interstitiis aequalibus, subtiliter punctatis, apice subrotundatis ; 

 antennis articulis secundo et tertio brevibus, sed hoc quam illo paulo 

 longiore ; sutura intercoxali profunda. 



Long., 21^-29 mm. 



This species is characterized by its comparatively large size, uniform 

 and even pubescence and punctation, by the short but yet not extremely 

 abbreviated third joint of the antennae, and by the front anterior angle 

 of each of joints four to ten of the antennae being acute but not pro- 

 longed. 



Oxford, February, 1873; Dry Bush; Chnstchurch ; Hokitika ; 

 Rangiora ; Akaroa, December i9th, 1874. The species varies consider- 

 ably in size ; one small specimen is marked in Mr. Wakefield's collec- 

 tion as found on a hill-top at Akaroa by Mr. Fereday. The species also 

 occurs in the North Island, as some portions of a specimen have been 

 received from Mr. Lawson, of Auckland. 



NOTE. I found a specimen of this species at Woodside (Waitemata 

 Harbour). Dr. Sharp also describes the larva and pupa ; these will be 

 published in a separate paper along with some belonging to other 

 groups, which I have not yet had time to examine. 



490. T. (OchOStemus) parryi, Cand. O. niger, sat nitidus, 

 breviter et sequaliter, fere sparsim fusco pubescens ; prothorace crebre 

 fortiter punctato, angulis posterioribus vix divergentibus ; elytris subtiliter 

 striatis interstitiis aequalibus, subtiliter punctatis, apice subrotundatis ;
