854 COLEOPTERA 



Length (rost. incl.), sf lines ; breadth, i. 



One individual, broken. Mr. T. Chalmer, Dunedin. 



1519. I. tibialis, n-s. Narrow, convex, piceous, clothed with 

 flat, brownish-grey scales and curved grey setae; antennae red; 

 tibiae and tarsi fusco-rufous. 



Rostrum shorter than thorax, medially carinated, its scales 

 reddish-grey. Prothorax rather broader than long, widest before the 

 middle, base feebly rounded ; its punctation concealed, convex, but 

 without superficial irregularities. Scutellum small. Elytra incurved 

 at base, where they hardly exceed the thorax in width ; humeral 

 angles oblique, sides sub-parallel, very gradually narrowed and not 

 abruptly declivous behind; striate-punctate, third and fifth inter- 

 stices a little elevated and nodose on the top of the hind-slope ; the 

 squamosity variegate, consisting of greyish scales and setae behind, 

 grey, yellowish-grey, and pitchy ones on the disc, but nowhere 

 forming a spotted appearance. Legs covered with scales and grey 

 hairs ; the front pa,irs of tibiae fiexuose, the posterior incurved. 



Undoubtedly congeneric with the preceding species notwithstand- 

 ing the narrow hind-body, which is very gradually and not much 

 narrowed behind, so that the apex is quite obtuse. The regular 

 incurvature of the hind tibia is quite unlike the usual flexuous form. 



Length (rost. incl.), 2-f lines; breadth, . 



I picked out my specimen from amongst a small collection re- 

 ceived from Mr. A. G. Harvey, of the Hutt, Wellington. 



1520. I. stolIdrLS, n.s. Narrow, moderately convex, fusco- 

 piceous; covered with minute yellowish and whitish-grey scales 

 and setae, those of the latter colour predominating, particularly 

 behind ; antennae fusco-rufous ; legs more obscurely coloured. 



Rostrum about as long as thorax, dilated apically, with a fine 

 median carina, its punctures squamose. Antennas, bearing grey 

 hairs, reaching to base of thorax, the scape attaining its apex ; 

 scape gradually incrassated ; first joint of funiculus largest, obtrian- 

 gular, second and third of nearly similar form, but smaller ; seventh 

 larger than sixth ; club elongate, oblong-oval. Prothorax about as 

 long as broad, obtusely rounded laterally, base and apex sub-trun- 

 cate ; disc convex, its punctation not coarse and concealed by the 

 clothing. Scutellum small, triangular. Elytra elongate-cordate, 

 shoulders oblique, not twice the width of thorax, attenuated and 

 compressed behind ; striate-punctate, the punctures oblong, the 

 third and fifth interstices, and the suture behind, somewhat elevated. 

 Legs clothed in the same way as the body ; posterior tibiae cavernose 

 at apex. Underside piceous, coxae and base of femora rufescent ; 

 clothed with rather long yellowish-grey hairs ; apex of prosternum 

 curvedly emarginate ; base of metasternum with a median fovea-like 

 depression ; the two basal segments of abdomen large, equal, broadly 

 impressed medially. 



A narrower form than I. pilosellus, with fewer scales but more 

 setae, and less evident sculpture.
