OF NEW ZEALAND. 431 



Allied to our T. squamulatus, from which its cavernous scrobes and 

 slender setulse will at once distinguish it. 



754. T. irritUS, Pascoe; Ann. Mag. Nat. Hist, February, 1877. 

 T. ovatus, indumento fusco tectus ; rostro crasso, capite breviore ; 

 scapo valido, setigero ; funiculo clavaque nitide rufo-ferrugineis, illius 

 articulo basali ampliato, secundo paulo breviore, caeteris transversis ; 

 prothorace fere in medio utrinque subangulato, supra modice convexo, 

 subtuberculato ; elytris subcordatis, prothorace paulo latioribus, basi 

 arcuatis, subpunctatis, interstitiis vix elevatis, squamulis paucis pallidus 

 adspersis ; pedibus rufo-ferrugineis. 



Long., 11 lin. 



Tairua (Capt. Broun). 



Size and shape of T. porculus, but with a remarkably stout scape, 

 and the prothorax with the side a little before the middle obtusely 

 angled ; in T. porculus the sides are rounded. 



755. T. clams, «..y. /'laf/*? castaneous, a little darker on the thorax, 

 legs reddish, scape dull, funiculus shining red ; sparingly clothed with 

 fine yellow and coarse erect fuscous sets. Antennce rather long and 

 stout ; the scape stout, shorter than the funiculus, with fuscous setas ; 

 the first joint of the funiculus large, obconical, second much larger than 

 third and of nearly the same form as the first, the others sub-globular, 

 club large. Rostrum stout, with a transverse line at the base, and a 

 longitudinal one extending towards the vertex, scrobes large but not 

 reaching the eyes ; the rostrum and head densely covered with fine 

 bright yellow setae. Thorax widest in front of the middle, a good deal 

 narrowed behind, moderately convex, with a few large punctiform im- 

 pressions, and the yellowish setse form a rather distinct dorsal line. 

 Elytra short, oviform, convex, very abruptly deflexed behind, and 

 slightly emarginate at the base ; they are striated, and the striae bear 

 coarse punctures. Legs moderate, clothed like the body, the four pos- 

 terior femora a good deal incrassated so as to appear obtusely dentate 

 below. 



The insect bears some resemblance to T. irritus, but is much more 

 brightly coloured, with a smaller and narrower thorax, the elytra, con- 

 sequently, seem relatively larger; the antennae are longer, with a longer 

 funiculus, that of T. irritus being only about as long as the scape. 



Length, \\ line. 



I found this species near Whangarei Heads. 



756. T. COrpulentuS, n.s. Somewhat similar to T. irritus ; the 

 antennce more robust, with the club pointed and the rostrum broader. 

 Thorax broader than long, somewhat dilated laterally near the middle, 

 narrowed in front and behind. The elytra are very large and broad, 

 the base as wide as the thorax behind, with oblique shoulders, nearly 

 straight sides, rounded and very abruptly deflexed, sub-perpendicular, 

 behind. 



The insect exhibits scarcely any sculpture, is piceous, with reddish 

 legs and antennae, the scape is stout, obscurely coloured and setose,
