OF NEW ZEALAND. 1103 



anterior angles. Thorax transverse, a little narrowed towards the 

 base, front angles acute and slightly produced, the posterior 

 rectangular. Scutellum broad, lunate. Eli/tra oblong, broadly 

 rounded behind, covering all but the extremity of the abdomen. 

 Legs moderately long ; femora clavate ; tibias rather slender, slightly 

 thickened apically, terminal process small and slender. Tarsi 

 apparently heteromerous, the minute basal joint concealed by the 

 ciliae at the apex of the tibia, terminal joint longer than all the basal 

 ones taken together. Coxce small, widely separated, the front pair, 

 placed rather far back. Prostcrnum with fine sinuous lateral sutures, 

 its process very broadly rounded behind ; there seems to be no 

 distinct suture between it and the middle-piece of the mesosternum, 

 which is finely marginated in iront, this margin is separated from 

 the prosternum by a transverse groove. The uietasternuni moderate, 

 shorter than the abdomen, which has five segments, the basal 

 segment large, broad and truncate between the coxae, the following 

 three about equal to one another, fifth rounded behind. 



The typical species, in general outline and sculpture, beai's some 

 resemblance to LcBinophloeus, the Australian L. contaminatus for 

 example, which, however, belongs to a different group of the family. 

 The extraordinary, almost hammer- shaped, basal joint of the antenna 

 will at once lead to its recognition. 



1958. T. lineatum, "•«• Gastancous, the labrum, mandibles, 

 palpi, and tarsi more or less fulvescent ; sparingly clothed with 

 minute, slender, pallid sette ; the surface densely and finely sculp- 

 tured and a little shining. 



Head with numerous fine punctures, a smooth linear impression 

 (longitudinal) behind, the lateral and frontal margins fine but dis- 

 tinct, and with a fine raised line behind each eye. Antennae pubes- 

 cent, the two basal joints finely sculptured. Thorax transverse, base 

 and apex nearly truncate, front angles acute, posterior rectangular ; 

 lateral margins fine, distinct, the basal much finer ; its sculpture like 

 that of the head ; the disc is slightly convex, and near each side 

 there is a fine raised line nearly parallel with the margin. Scutellum 

 finely margined in front, with a groove behind. Elytra finely mar- 

 gined, very slightly curved at the sides, these nearly vertical ; dorsum 

 broadly impressed across the middle, its side limited by a fine raised 

 line, which recurves at the base and there unites with a still finer 

 one extending to the apex ; between this inner line and the one next 

 to it there is but a comparatively narrow space, as is the case with 

 the next one, and so on ; so that there appear to be a sutural stria 

 and five more or less evident longitudinal lines, enclosing unequal 

 areas, on each elytron ; however, only two discoidal lines are well 

 marked, the others can be seen when examined sideways. The 

 metasterimm is grooved behind. 



Length, 1^ lines ; breadth, quite f line. 



Tiritiri Island. Only one specimen has been found. Its dis- 

 coverer, Mr. Sandager, kindly placed it at my disposal.
