fourth of the width of the first ; daws simple. The tibiae are finely 

 pilose inwardly near the apex, and the antennae are very sparsely 

 pubescent. 



Length, i J line. 



I found one individual only in the Parua Forest (Whangarei Har- 

 bour) ; the punctation of the elytra, and peculiar form of the basal joint 

 of the tarsus are sufficient to lead to the recognition of this species. 



1107. A. mimitum, n.s. This minute species is almost entirely 

 without sculpture, though on a careful examination some feeble acicu- 

 late striae and a few punctures may be seen on the elytra; the body is 

 of the usual form, and shining black; the antenna are infuscate, and the 

 legs reddish-testaceous ; the tarsi are stout ; the joints of the antenna 

 become larger towards the extremity, but the last joint is nearly as large 

 as the ninth and tenth conjointly. 



Length, f line. 



I found three specimens of this species in the vicinity of Whangarei 

 Harbour. 



Group- GALERUCIIXE. 



Head moderate, free, or more or less immersed in the thorax ; 

 forehead narrow, usually furrowed; with callosities, and an inter-antennal 

 carina. Labrum transversal, hollowed, more rarely truncated. Mandibles 

 not, or only slightly, prominent, wide at the extremity, bi-dentate or 

 multi-dentate. Inner lobe of the maxilla short and broad ; the external 

 palpiform, more slender and shorter. Maxillary /^/ quadri-articulate ; 

 the basal joint short, second and third obconical and more or less 

 swollen at the extremity, the fourth acutely conical, rarely obtuse. 

 Under-lip with a short mentum. The tongue but little developed, oval, 

 with tri-articulate feelers. Eyes moderate, sub-oblong or rounded, finely 

 granulated, entire. Antenna inserted on the forehead between the 

 eyes, and at some distance from their inner margin, converging at their 

 base, proceeding from the cavities of their orbits ; generally filiform, and 

 at least half the length of the body. Prothorax ordinarily narrower than 

 the elytra, transversely quadrate, seldom oblong, with the lateral margins 

 always distinct. Scutellum constantly visible, moderate, somewhat 

 variable. Elytra elongate, oblong, briefly oval, sometimes abbreviated 

 or slightly truncated at the end. Prosternum narrow, hardly perceptible 

 between the coxae, rarely wide, never becoming transverse ; its episterna 

 overlapping the cotyloid cavities. Legs long and slender, or shorter and 

 robust ; femora normal, or the posterior very much inflated and adapted 

 for leaping ; tarsal claws rarely simple, generally appendiculate or bifid. 

 Anterior coxa conical and rather prominent.

This genus is founded for the reception of New Zealand insects, 

 which, though closely allied to Superus and Superodes, do not exactly
