OF NEW ZEALAND. 847 



I cut one, not quite mature, specimen out of a kauri log on the 

 Waitakerei Range. 



Group MORDELLIDJE. 



Zeamordella. 



Nov. gen. 



Differs from Mordella. Terminal joint of the maxillary palpi 

 large, broadly triangular, anterior margin concave, united exactly_in 

 the middle to the penultimate. Hind legs short ; their tarsi robustT 

 with coarse ciliae at the extremity of each joint. Pygidium with a 

 deep sinuous suture. Scutellum semicircular. 



1505. Z. monacha, n.s. Lanceolate, arched, sub-opaque, 

 black ; three or four basal articulations of the antenna, and stalk of 

 the palpi, infuscate ; elytra with whitish spots. 



Head finely punctured, densely clothed with short brassy hairs. 

 Antennas pubescent, joints 5-10 serrate, eleventh ovate. Prothorax 

 broader at the base than the elytra, strongly rounded and narrowed 

 towards the front, base medially lobate ; its sculpture consists of 

 irregularly-formed linear impressions; it is clothed like the head. 

 Elytra gradually narrowed posteriorly, apices obtusely rounded, 

 densely sculptured pretty much in the same way as the thorax ; the 

 darker portions are covered with cinerous pubescence, whilst pale- 

 yellow hairs form spots ; these are, on each elytron, one humeral, 

 two behind it but before the middle, one behind the middle, a broad 

 sutural line extending as far as, and having a tendency to unite with, 

 the median spot, and an elongate ante-apical sutural spot. Legs 

 robust, clothed with pale-yellow hairs. Underside pitchy-black, 

 sculptured like the upper surface, and clothed with greyish hairs. 

 Pygidium covered with griseous hairs at the base. 



Length, if lines ; breadth, -|. 



I shook two off birch-trees near the residence of Mr. Hampton, 

 at Pokeno, Auckland.

Nicasana (p. 4 2 7)- 



1506. N. COncinna, n.s. Oblong-ovate, medially contracted, 

 moderately convex, variegate, densely covered with depressed 

 rounded scales and fine erect setae; legs testaceous, antennae ru- 

 fescent. 



Rostrum continuous with, but narrower than, the head, punctate, 

 with an excessively-fine longitudinal line, covered with grey scales. 

 Antenna stout, scape shorter than the funicle, gradually incrassated ; 

 basal joint of fum'culus largest ; second obconical, not very much 

 smaller than first ; joints 3-6 nearly momliform, seventh larger than 

 sixth, transverse ; club ovate, distinct. Head plane above. Pro- 

 thorax transversal, rounded laterally, punctate, covered with white 

 and greyish scales, but with a broad vitta at each side, composed of 

 smoky-brown scales. Scutellum triangular, pallid. Elytra
