OF NEW ZEALAND. 1201 



scutclluiii, visible. Elytra wider than thorax at base, shoulders 

 widely oblique in the longitudinal direction, slightly widely dilated 

 behind these, otherwise subparallel, apices not prolonged, posterior 

 declivity not abrupt, scutellar region depressed ; each with six dorsal 

 rows of well-defined punctures, third aiid fifth interstices more or 

 less unevenly raised, the fifth terminating in a large nodosity be- 

 hind, the suture raised apically. Corbels of hind Libitc narrowly 

 cavernous, with two rows of ciliuB. 



A rather bright-looking species. Its nearest congener is /. cgrecjlus, 

 which also has narrowly-cavernous corbels, but differs in possessing 

 a distinct scutellum, narrower shoulders and abruptly - deflexed 

 apex, &c. 



Length (rost. inch), 3f ; breadth, 1^ lines. 



Described from a specimen in my collection, received, I think, 

 from Mr. C. JNl. Wakefield, formerly of Christchurch. 



2127. I. albonotata, ^i-s. -B^-oacZ, slightly convex ; squamosity 

 variegate, on thorax fusco-testaceous with some black, redder on 

 rostrum, on elytra ash-coloured but paler near the base, with several 

 spots of nearly-pure white ; setaB greyish, placed in rows on the 

 elytra and decumbent there, on thorax erect and coarser. 



Rostrum indistinctly carinate. Antenna red ; scape with long 

 and short setje, attaining thorax ; first two joints of funiculus 

 elongate, equal, 3-6 longer than broad; club fuscous, opaque, ovate, 

 acuminate. Tliorax about as long as broad, widest before the 

 middle, broadly constricted or depressed in front, longitudinally de- 

 pressed in front of the scutellum ; irregularly rugose, the punctation 

 hidden. Scutelhtm small, sunk, the elytra raised at either side of 

 the cavity. Elytra nearly double the width of thorax, shoulders 

 obtusely rounded, sides scarcely curvate, much narrowed behind, 

 apices acutely prolonged ; third interstices distinctly, fifth only 

 slightly elevated at the base, hardly at all along the dorsum, posterior 

 elevations on fifth larger than those on third ; suture raised along 

 hind slope ; each elytron with six discoidal rows of moderately large 

 and distant punctures, sometimes onh- four or five in each row, with, 

 on some parts, smaller ones intervening, but apparently altogether 

 wanting across the middle of the disc. Legs with scales and setce, 

 hind thighs marked with a large white spot or band ; tibiae and tarsi 

 infuscate-red, posterior corbels narrowly cavernous. 



Underside bearing scales and slender, greyish, decumbent setse ; 

 head closely, finely, transversely rugose. 



Mandibular scar well marked, consisting of a rather deep fovea 

 on an obtuse prominence, nearly similar to that seen in I. sulcifcr. 



The white spots of themselves differentiate this species from 

 Nos. 1231 and 1232. All three are very much alike, having un- 

 usually broad elytra. 



Length (rost. inch), 3f ; breadth. If lines. 



One, received from Mr. S. W. Fulton (from Taieri), from whom I 

 have also a sexual or varietal form of I. nigellus, with acutely-pro- 

 duced apices, and covered with dull yellowish-grey or pale-brown 

 scales.
