OF NEW ZEALAND. 1223 



rugose, the third and fifth rather broader and more elevated than 

 the others ; the pleur£B rather abruptly deflexed ; some of the scales 

 are similar in colour to the derm so that the true sculpture of the 

 interstices is not very readily detected. 



Underside blackish, clothed in much the same way as the upper 

 surface. 



S- . Length (rost. inch), 5^-5^; breadth, lf-2 lines. 



The first specimen was brought from Mount Arthur by Mr. T. 

 F. Cheeseman, and I possess some others which were taken off 

 spear-grass on Mount Peel, at an elevation of 5,500ft., by Mr. G. V. 

 Hudson and Mr. C. W. Palmer, of Wellington. 



Gronp-HYLOBIID^. 



Eiratus. 



2154. E. pyriformis, ".•'>■• Elongate, subovate, convex, some- 

 what shining, bearing only a few fine grey hairs ; pitchy-red, antennae 

 red, club blackish. 



Bostruni scarcely as long as thorax, very gradually and slightly 

 expanded apicalh', neither closely nor coarsely punctured ; eyes 

 moderate ; head dilated and almost smooth " behind the eyes. 

 Antcnnce stout, scape flexuose and incrassated apically ; first joint 

 of funiculus large, second rather shorter and much more slender, 

 joints 3-7 increase in breadth, so that the seventh is nearly as 

 broad as the base of the club, which is large, ovate, and opaque. 

 Thorax distinctly longer than broad, gradually narrowed anteriorly, 

 only very slightly constricted at apex ; closely, coarsely, and rugosely 

 punctate. ScnteUum small. Elytra subcordate, bisinuated and 

 finely marginated at base, where they hardly exceed the thorax in 

 width, widest behind the middle, their apical portion much narrowed ; 

 somewhat uneven above, impressed before the middle, rather 

 coarsely punctate-striate, interstices rather narrow and convex and 

 a little rugose. Tibia strongly armed at the extemity. 



Very much like E. versutus, exactly similar in structure, the 

 thorax more gradually narrowed towards the front, and with a more 

 or less obvious longitudinal elevation on tlie dorsum ; the hind-body, 

 though just perceptibly curved at the sides, does not become con- 

 contracted till in line with the hind slope, but there the narrowing 

 is rather abrupt ; the strite are well marked, whereas in E. versutus 

 the strise are more apparent than real, the punctures being large and 

 contiguous. 



Length (rost. inch), 1^- lines ; breadth, ^ line. 



Mount Arthur. Two examples. 



2155. E. ru^OSUS, "-s. Convex, subovate, dull fusco-piceous, 

 slightly rufescent, antennae red, club black, very sparingly clothed 

 with fine grey hairs. 



Another near congener of E. versutus, the tliorax, however, more 

 coarsely and rugosely punctured; elytra quite cordiform, their series 

 of punctures very coarse and irregular, and with costiform inter-
