behind ; front and middle coxcb sub-globose ; the posterior lamelliform, 

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

 /rt-rw' five-jointed, often provided with lamellae underneath. Abdomen com-

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 ; antenual spaces very small, broadly separated ; antennce 

 with joints two and three but httle 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 coxce. 

 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 aKpaliter fusco-pubescens ; prothorace 

 crebre punctato, angulis posterioribus divergentibus ; elytris subtiliter 

 striatis, interstitiis cequalibus, subtiliter punctatis, apice subrotundatis ; 

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

 longiore ; sutiira intercoxali profunda. 



Long., 2i|-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 antenn-ae, 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 19th, 1874. The species varies consider- 

 ably in size 5 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. — 1 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.
