Taieri, Otago : Mr. S. W. Fulton. Four examples. 



Tigones. 



Nov. gen. 



Eostrum shorter than thorax, narrower than the head, slightly 

 narrowed before the middle, dilated and triangularly grooved near 

 the apex, more or less finely carinated ; scrobcs deep, apical, visible 

 from above. AnteimcB modexsitely long ; scape gradually incrassated, 

 attaining the thorax ; funiculus 7-jointed, basal joint largest but 

 not very elongate ; second similar in form but smaller, joints 3-7 

 sub-obconical ; club tri-articulate, oblong-oval. Eyes distant from 

 thorax, prominent, longitudinally oval, moderately facetted. Pro- 

 thorax quite as long as broad, truncate or indistinctly bisiuuate at 

 base, without distinct ocular lobes. Scutclluvi distinct. Elytra 

 cordate or oblong-cordate, a little broader at base than the thorax, 

 humeral angles oblique, apices more or less produced. Legs mode- 

 rately long, robust ; femora clavate ; tibia, flexuose, the anterior 

 mucronate, the others narrowed beyond the middle, considerably 

 expanded and cavcrnose at apex, and denticulated along their inner 

 or front face ; tarsi hispid, their basal joint rather shorter than the 

 apical and thickened at the extremity, second short, triangular, 

 penultimate bilobed, claws simple. Anterior coxce prominent, con- 

 tiguous ; intermediate rounded, separated by the narrow mesosternal 

 process ; posterior distant. Metasternum short. Abdomen with five 

 segments, basal largest, inter-coxal process obtuse, second about as 

 long as the following two, its hind suture straight, the anterior 

 oblique towards each side. EpipleurcB narrow. 



Allied to Ireniimis, but with prominent eyes, &c. 



Asaphia is another cognate form, bv;t in that genus the elytra 

 are nearly twice the width of the thorax at the base, with prominent, 

 obtusely rectangular, humeral angles ; it is distinguished from 

 Ircnimus and the Australian Perperus in having prominent eyes. 



1521. T. caudata, "-5. Sub-ovate, moderately convex, fusco- 

 rufous, densely covered with small, depressed, sometimes yellow, 

 sometimes greyish, scales, intermingled with fine, erect, pale setae ; 

 antennae red. 



Rostrum shorter than thorax, dilated apically, with a fine median 

 carina, punctate and squamose. Antenna elongate, with greyish 

 hairs ; scape shorter than funiculus, extending backwards to apex of 

 thorax ; first joint of the funicle stouter but not much longer than 

 second, joints 3-7 decrease in length but become slightly broader, 

 the three last being nearly moniliform. ProtJiorax quite as long as 

 broad, narrowed in front, rounded at the middle, nearly straight, 

 yet a httle narrowed,- behind ; its posterior angles, owing to scales 

 and set£e, appearing to project ; punctate, without inequalities of 

 surface. Scutcllum distinct. Elytra cordate, broader than thorax 

 at base, more so near the middle, shoulders oblique, gradually 

 narrowed, and declivous, posteriorly, apices considerably produced
