OF NEW ZEALAND. 1041 



yet quite oblong, their punctures not forming striae. Hind-body 

 longer, the extremity of each segment pallid, apparently mem- 

 branous, and finely and densely sculptured. The whole insect 

 much more elongate and slender. 



Length, 1|- lines ; breadth, nearly line. 



One example, found near Howick. 



1863. I. moroSUS, n.s. Fusco-castaneous; the sides and base 

 of thorax, scutellum, and shoulders chestnut-red ; hind-body casta- 

 neous, the basal and apical segments paler ; legs, palpi, and five 

 basal joints of antennas rufo-fulvous, the other joints blackish. 



Head large, slightly uneven, less distinctly punctured in 

 front than elsewhere, its four impressions well marked ; it 

 bears some slender yellow hairs. Thorax transverse, its sides 

 rounded in front, gradually narrowed behind, hind angles rectan- 

 gular ; the two discoidal impressions distinct, the surface clothed 

 and sculptured like the head. Elytra oblong, apices subtruncate ; 

 their punctuation in series, appearing to form striae, and with slightly- 

 elevated longitudinal interstices ; almost destitute of pubescence. 

 Hind-body almost as broad as and rather longer than elytra, densely 

 and minutely sculptured, and also with fine indistinct punctures ; 

 near the middle of each side of the four basal segments there is a 

 small smooth spot ; pubescence yellowish, shorter and more erect on 

 the penultimate segment. 



When compared with No. 220 it will be noticed that the head of 

 this species is more narrowed in front so that it does not seem as 

 large, it is also more rough-looking, owing to the larger punctures 

 and rugose intervals ; the sculpture of the thorax and elytra is 

 coarser ; the sides of the thorax towards the base are more de- 

 pressed ; the basal dorsal segment in my specimen is entirely 

 exposed, instead of being more than half covered as in /. genalis. 



Length, 14- lines ; breadth, - line. 



One example, found near Howick. 



1864. I. fultoni, ti.s. Subparallel, depressed, a little shining; 

 variegated-chestnut, thorax of a paler reddish-chestnut colour ; the 

 legs and five basal joints of antennae rufo-fulvous, the other articu- 

 lations fuscous. 



Head as large as thorax, rather narrow for this genus, 

 straight behind the eyes, minutely sculptured all over, and finely 

 but distinctly punctured, but with fewer punctures in front ; 

 interocular impressions distinct ; clypeus and labrum testaceous, 

 membranous. Antenna longer than head and thorax ; basal joint 

 stout, slender at base ; second much shorter and narrower ; third 

 longer than second, but more slender ; fourth and fifth bead-like ; 

 4-10 more or less transverse. Thorax a good deal broader than 

 long, widest near the front ; anterior angles rounded, the posterior 

 rectangular, but not acute, the sides a little sinuated and narrowed 

 in front of the latter ; the entire surface is minutely sculptured, the 

 punctuation moderate, more sparing along the middle and in front,
