New Zealand Coleoptera. 95 



Tetrorea sellata, n. s. 



Sat elongata fere gracilis, nigricans, pube variegata 

 vestita, elytris ante medium plaga pallidiore oblique 

 descendente, pedibus articulisque 1 — 4 antennarum 

 maculatis, harum articulis 5 — 10 nigro-fuscis, singulo ad 

 basin late pallido-annulato ; elytris utrinque pone scu- 

 tellum tuberculo parum elevato, singulo ad apicem 

 rotundato ; antennis pedibusque fere gracilibus. Long. 

 11 — 12 mm. 



Eyes comparatively little separated on the vertex. 

 Thorax with large lateral prominence, and with' broad 

 tubercle on each side of the middle. Scutellum clothed 

 with black pile. Each wing-case has an obscure eleva- 

 tion near the base, and numerous large punctures about 

 the scutellum ; the lateral portions are also a good deal 

 punctate ; the surface is variegate with obscurely- 

 coloured down, and there is a patch of pale colour 

 descending obliquely from behind the shoulder, and 

 meeting its fellow of the opposite side just in front of 

 the middle. The legs are rather slender, and bear only 

 a few erect white setae. 



Greymouth ; Helms. 



This departs from the typical species by the form of the 

 apices of the elytra, and by the eyes being less sepa- 

 rated on the vertex, but it cannot with advantage be 

 separated at present as a distinct genus, especially as 

 it bears a great general resemblance to T. discedens. 

 The colour of the down on the scutellum, independently 

 of more important characters, permits it to be dis- 

 tinguished at a glance from T. discedens. 



Tetrorea discedens, n. s. 



Pube variegata, ex parte majore fusco-olivacea, ves- 

 tita, elytris pone basin plaga magna communi pallidiore, 

 antennis pedibusque conspicue maculatis, abdomine 

 utrinque flavo-maculato ; prothorace in medio plaga 

 nuda, nitida ; elytris utrinque pone scutellum tuberculo 

 elevato, etiam ad medium et ante apicem penicilla parva 

 instructis. Long. 11 — 13 mm. 



Antennae reaching slightly beyond the extremity of the 

 body, very distinctly maculate, the basal joints more or 

 less ferruginous. Thorax with an angular prominence
