OF NEW ZEALAND. 591 



tinct, rather sharply defined in front and rounded externally ; the apices 

 are curvedly-excised, and acute at the suture and outward extremity, the 

 latter being produced ; their surface is impunctate ; each has four longi- 

 tudinal furrows, that nearest the suture being attenuated towards the 

 scutellum, the second extends from the base to beyond the hind legs, 

 the third longer than the second, the fourth marginal ; all four are 

 clothed with whitish pubescence. The general ground-**?/^/- is of 

 various shades of black, sometimes reddish, at others greenish. The 

 colour of the legs varies from testaceous to greenish. 



Length, 5-6 lines. 



According to Bates, who examined Fabricius' type in the British 

 Museum, there is no difference between it and the JV. acutipenne of 

 White, which must, therefore, be erased from the list of the genus. 



The descriptions of this, as well as the preceding species, have been 

 compiled from specimens I had collected at Tairua, and will, I hope, 

 put an end to the previous confusion. 



1030. N. neglectum, n.s. This species, in its general outline, 

 sculpture, and clothing, very much resembles N. sulcatum, but it differs 

 materially in the form of the apex of the elytra and the sculpture of the 

 head. 



The smooth dorsal space between the antennae, which in N. sulcatum 

 is entire, is in this species divided by a distinctly impressed line on the 

 vertex, and the furrows are much less distinct. The posterior angles of 

 the thorax are somewhat obtuse. The apices of the elytra are rounded. 



The ground-colour is greenish-black, the pubescence whitish. 



Length, 5^ lines. 



This species, I imagine, had been overlooked by previous authors, or 

 confounded with N. sulcatum. The specimen I examined was found by 

 me at Tairua. 



Group LAMinXE. 



Ligula coriaceous or corneous, rarely membraneous, without para- 

 glossse. Maxilla bilobed. Last joint of the palpi fusiform or aciculate. 

 Labrum free and horizontal. Head ordinarily vertical in front, its fore- 

 head forming a sharp angle with the vertex. Antenna always inserted 

 at a distance from the mandibles in the anterior emargination of the 

 eyes. Pronotum confounded with the flanks of the prothorax. The 

 anterior tibia with an oblique internal furrow ; the intermediate often 

 with a similar furrow on the external face. The mesonotum provided 

 with organs of stridulation. 



Hexatricha. 



White. (?) 



Antenna rather longer than body, setaceous; scape narrow at the 

 base, but abruptly and equally thickened beyond ; second joint small ; 

 third longest ; joints one to six strongly ciliated externally. Eyes reni- 

 form, finely yet distinctly facetted. Palpi of moderate length; the 

 terminal articulation shorter than the penultimate and produced to a
