OF NEW ZEALAND. 1005 



being gone, I am not very sure about the details : there is no seta in 

 this species at the hind angle of the thorax. 

 Also sent by Mr. Helms from Greymouth. 



1801. T. alpinalis, n.s. Convex, subovate ; pitchy-black, 

 nitid ; palpi, antennae, and legs rufo-testaceous. 



Head with broad, shallow, frontal foveae, and, at inner side of 

 each eye, a well-marked narrow channel. Antenna as long as head 

 and thorax, bearing slender yellow setae and pubescence, their three 

 basal joints glabrous. Prothorax about as long as broad, narrower 

 than elytra, rounded laterally, and distinctly sinuated before the 

 rectangular posterior angles, narrower in front than behind ; disc 

 smooth, canaliculate, the whole base more or less depressed and 

 punctate, the fossae large and equidistant from the middle and sides, 

 the space (small) at each hind angle depressed and punctate. Elytra 

 longer than broad, convex, their sides strongly marginated and well 

 rounded ; distinctly punctate-striate, the punctures large, the striae 

 obsolete near the base, interstices smooth and convex, the eighth 

 carinate behind. 



Agrees in most respects with the description of T. l&viventris, 

 but the whole base of the thorax is more or less punctate, and the 

 external elytral striae are about as obvious as the others. The 

 terminal articulation of the labial palpus is stout, and very abruptly 

 truncate at the extremity. The setae on the hind angles of the 

 thorax are distinct, and there are others on the wing-cases. 



1802. T. debilis, n.s. (Sharp; Trans. Eoy. Dub. Soc., 1886, 

 p. 373.) Piceus, antennis pedibusque testaceis ; prothorace basi 

 punctato, angulis posterioribus minute prominulis, subobtusis ; 

 elytris sat profunde striatis, striis subcrenato-punctatis. 



Long., If mm. 



Antenna rather feeble. Head rather narrow ; eyes small and not 

 prominent. Thorax finely and very evenly margined at the sides ; 

 the sides much curved, scarcely at all sinuate behind ; the base a 

 little rounded on each side, so that the hind angles would be quite 

 obtuse except that they are a little prominent externally ; finely 

 punctate across the basal portion, with fine median channel, but 

 without lateral impression. Elytra with the sutural striae rather 

 deep, the external finer ; their punctuation of a rather peculiar 

 nature, so that it is intermediate between crenation and punctuation. 



This species has a very Trechoid appearance, and will be dis- 

 tinguished by its small, smooth eyes. Although I have seen only 

 two females, I do not detect anything to distinguish it from this 

 genus. 



Bealey. Helms ; two examples. 



1803. T. cinctUS, w.s. Broad, slightly convex, moderately 

 glossy ; nigro- fuscous ; the sides of thorax and elytra, and a large 

 apical space on these latter, as well as the femora and antennae, more 

 or less testaceous ; tibise and tarsi rather more rufescent.
