678 COLEOPTERA 



furrows almost impunctate, the others distinctly ; interstices plane, rather 

 closely punctulated and slightly rugose. Antenna sub-serrate, second and 

 third joints short, the latter the longer. Sternum rather coarsely, the 

 flanks of the prosternum finely and remotely, punctured. The suture 

 between the intermediate coxoe distinct, consisting of a groove, not a mere 

 linear impression ; the margins of the mesosternal cavity are a good 

 deal elevated anteriorly and rather sharply defined ; coxal lamina well 

 developed. 



When contrasted with T. wakefieldi and its allies the difference of 

 form at once strikes the eye, the elytra being curved outwardly behind the 

 middle ; their breadth near the base is 2\ lines, in T. wakefieldi it is 

 3 lines ; the tarsi are more slender, and the mesosternal cavity differs. 



Length, 9 lines; breadth, 2|. 



I found one individual only at Parua, Whangarei Harbour. 



OBS. In T. wakefieldi the prosternum is sparingly and finely pnnc- 

 tured, the metasternum finely and distinctly. T. rugosus has the middle 

 of the prosternum rather coarsely punctured, its flanks finely and 

 remotely ; the margins of the mesosternal cavity are broad and a little 

 elevated ; the suture between the middle coxae is linear, but the anterior 

 angles of the metasternum at that point are cut away, thus leaving an 

 evident gap between its front angles and the coxae. T. foveolatus has 

 convex elytral interstices, and is finely and distantly punctured under- 

 neath. 



These remarks will aid in the separation of the species of this rather 

 difficult genus. 



1183. T. angUStUS, n.s. Body rather narrow and almost parallel, 

 shining,, black, the sides of the elytra rufescent posteriorly ; clothed with 

 fine yellow hairs. 



Head coarsely punctured. Prothorax longer than broad, with rather 

 prominent posterior angles, coarsely and closely punctured, least so on 

 the disc. Elytra elongate, almost parallel, punctate-striate, the inner 

 striae not very evidently punctured, interstices punctulated. 



Under-side more or less punctulate and pubescent. Intercoxal process 

 of the metasternum rather narrow, with a fine suture between the coxx. 

 Antenna dull, second and third joints short, the latter rather longer, 

 joints 4-10 slightly produced inwardly at the extremity. 



The most parallel-sided species of the genus, narrow in proportion 

 to its hmgth, its thorax very perceptibly longer than broad. Differentiated 

 from T. cervinus in coloration, in the normal form of the mesosternal 

 cavity, fine intercoxal suture, &c. 



Length, 10 lines ; breadth, 2\. 



Described from one example discovered at Martin Bay, Otago, by 

 Professor Hutton. 



1184. T. parvulus, n.s. Shining, thorax rufo-piceous, elytra dark 

 castaneous, clothed with fine yellow hairs. 



Head rather distinctly punctured. Prothorax longer than broad, with 

 two foveas near the base, moderately closely punctured. Elytra punctate- 

 striate, the inner striae indistinctly punctured, the intervals between the 

 grooves punctulated and a little rugose. Antenna elongate ; second and
