prosternum is slightly broader and pubescent. Tiie mesosternum 

 has its front margin more sharply defined. 



Length, 4^ ; breadth, If lines. 



Karaka, near Drury. Five, taken off Cordijlinc banksi. 



AmplectopuS (Gen., p. 1137, Part V.). 



2526. A. pallicornis, "■«• Oval, convex, shghtly shining, 

 infuscate-red, tarsi yellow, clothed with fine, depressed, greyish- 

 yellow hairs. 



Head finely punctured. Thorax slightly bisinuate at the base, 

 quite indistinctly punctate. ScuteUum curviliuearly triangular. 

 Elytra oblong-oval, apices a little explanate ; their sculpture fine, 

 not close, that of the basal portion apparently grtinular. 



Antcnnce testaceous, first joint reddish, oblong ; second sub- 

 quadrate, oblique at the base and apex, its point of articulation 

 narrow and quite at one side ; third longer than broad, slender near 

 the base, its apex emarginate at the inner portion ; fourth nearly as 

 long as the preceding one at the outside, but narrowed and produced 

 inwardly ; fifth of similar form but smaller ; 6-10 transverse ; tenth 

 not broader than the ninth. 



Underside reddish, very finely pubescent ; metasternuvi large, 

 more distinctly punctured than the abdomen, the suture rounded 

 between the middle coxas. 



Length, f ; breadth, i line. 



Mount Pirongia. Two, found by Mr. A. T. Urquhart. The 

 structure of the antennse, and their coloration, differentiate this 

 species. There are other species, but they cannot be described at 

 present, as the anteni:ite are hidden.

2527. P. tumipes, ^i-s. Oblong, hardly at all convex, opaque ;

Head irregularly punctate and rugose. Tliorax rather broader 

 than long, widest near the front, apex emarginate, base bisinuate ; 

 lateral margins somewhat reflexed, irregularly serrate, or with four 

 or five indentations, not always alike, posterior angles generally 

 obtuse ; the disc more or less closely and rugosely punctured, the 

 depressed space between it and the side with some small setigerous 

 granules ; a linear impression extends from the base to the apex, 

 ending in a small notch in front of tiie scutellum, which is distinct. 

 Elytra oblong, rather wider than the thorax at the base, the 

 shoulders obtusely prominent ; the sides a little undulate behind 

 the middle, rather abruptly bent inwards, and unequally elevated, 

 or nodose, behind the top of the posterior declivity ; their sculpture
