36 COLEOPTEKA 



the surface is almost smooth. Elytra elongate, oval, with tubercular 

 shoulders, they are slightly convex, and only a little sinuated behind ; 

 the striai are fine, not very perceptibly punctated, the first three pairs 

 become confluent at the end, the seventh is bent towards the apex, 

 where it is deepest, and the interval between it and the marginal chan- 

 nel is a little elevated and narrowed ; the interstices are slightly elevated, 

 the third, fifth, and seventh are rather broader than the others, and all 

 bear more or less distinct, transverse impressions, which are most 

 obvious near the apex ; there are a short scutellar stria and puncture on 

 each elytron, and a row of punctiform impressions along the marginal 

 channel. The mentum tooth is rather short, and the posterior tro- 

 chanter rather long. 



Length, 8| ; breadth, 2-i- lines. 



Allied to T. p/aniiiscii/a, of still more elongate sub-parallel outline ; 

 the thorax in its widest part measures 2 lines across, the elytra 2|-. 



I have received one specimen from Professor Hutton, who found it 

 at Martin's Bay, on the west coast of Otago. 



75. T. planiuSCUlUS, White; Voy. Er. Terr., Ins. p. I. Body 

 plain black, not very brilliant, with the palpi, tarsi, and three first joints 

 of the antennae pitchy-red, the last eight antennal joints paler and hir- 

 sute. Head rather long, and nearly as wide as the thorax, wnth not 

 very prominent eyes, almost truncate labrum, two elongate frontal fovea? 

 united near the middle by a transverse line, and smooth vertex. Pro- 

 t/iorax subquadrate, a little transverse, the sides margined, rounded 

 anteriorly, and a little incurvedly narrowed behind, with rectangular 

 posterior angles ; it is very little convex, with two large basal fovese, and 

 the marginal channel continued along a portion of the base at each 

 side ; the dorsal furrow almost reaches the base, but is obliterated in 

 front, where there is a slightly elevated lunate space which is scored 

 with longitudinal lines, and the scutellar region is similarly, but less dis- 

 tinctly impressed ; the disc is very finely strigose. Sciitellum scored 

 along its base. Elytra rather long, not much dilated near the middle, 

 sinuated at apex, with almost tubercular humeral angles ; each elytron 

 bears seven finely punctured, discoidal strise, those nearest the suture 

 mere lines, they become deeply impressed near the apex, where they 

 are confluent ; the interstices are broad and plane on the disc but con- 

 siderably elevated posteriorly, the first and third, fifth and seventh, are 

 united at the end ; there is a marginal row of punctiform impressions, 

 and the marginal channel is widened and rugosely sculptured behind. 

 Abdomen and sternum black. The le^s are rather slender. 



Length, 12^ ; breadth, nearly 4 lines. 



This species may be at once recognised by its sub-depressed, elon- 

 gate form. The description given corresponds with two specimens 

 which were sent to me from Wellington by Mr. J. Buchanan. 



76. T. dentiferus, n.s. Oblong, robust, rather flat above ; head 

 and thorax deep, shining black ; elytra with a silky gloss ; legs and 

 antennae rufo-piceous ; tarsi pitchy-red ; palpi paler. Head moderate.
