whereon the bro^^^^ occupies a considerable portion of the dorsal space, 

 and forms a small spot near each side not far from the front angle ; on 

 the elytra the darker colour prevails, leaving the apex, suture, two basal 

 spots, and two flexuose fasciae, yellow ; the legs are yellowish, as are also 

 the six basal joints, and the apex of the other joints of the antennae, the 

 rest being fuscous. 



Head nearly smooth, with prominent, oval, finely facetted eyes. 

 Thorax widest behind, where it is a little sinuated, rounded towards the 

 front, broader than long, finely and distantly punctate, with fine hairs 

 proceeding from the punctures ; these hairs correspond in colour with 

 that part of the thorax on which they are placed. Elytra obovate, as 

 wide as the thorax at the base, their shoulders slightly overlapped by its 

 hind angles ; the most evident part of their sculpture consists of trans- 

 verse lines, and a sutural stria on each ; the scant pubescence conforms 

 in colour to that of the spaces on which it occurs. The legs are long 

 and slender, finely hispid, the middle tihice are much bent, the others 

 straight, the anterior the shortest, and the terminal spurs are distinct but 

 slender ; the tarsi are linear. 



The antenncc are as long as the body, slender, with an elongate in- 

 distinct five-jointed club ; first joint elongate, not stouter than second, 

 which is elongate-oval, and as long as the third ; joints three to five are 

 slender, elongate, and about equal to one another ; sixth a little shorter 

 than the preceding ; the seventh, ninth, and tenth increase in size ; the 

 eighth is a little broader and not much longer than the sixth ; eleventh 

 oviform ; they are pubescent. 



Length, i line ; breadth, nearly \. 



I found one specimen at Tairua, and two near Whangarei Harbour. 

 It somewhat resembles a ScapJiisonia in form, and, with the two following 

 species, will ultimately form a distinct genus. 



280. M. bicolor, n.s. Thorax and basal half of elytra yellowish, 

 the apical portion of the latter, and the head, blackish, the legs and 

 greater part of the antennte are of the same dark colour. 



Head shining, with a few fine punctures. Prothorax similar in form 

 to that of M. undiilata, but less depressed in front, its surface is finely 

 punctate, and sparingly clothed with yellow hairs. Elytra obovate, a 

 little truncated at apex so 'as to expose the ventral segment ; their sculp- 

 ture consists chiefly of impressed transverse lines, the yellow hairs are 

 almost confined to the anterior portion, though there are a few behind. 

 Legs long, moderately stout, the tibice straight, and the_7^^/ slender. 



Length, i i line, breadth nearly j. 



I have only one individual, which I found at Tairua. 



281. M. nebulOSUS, n.s. Oval, convex, variegate; head and 

 thorax blackish, elytra reddish along the base, dark-brown elsewhere, 

 except where the yellow hairs form ill-defined fasciae, legs obscure red, 

 last joint of antennre blackish. 



Head small, punctate, shining. Thorax considerably rounded towards 

 the front, apparently punctate, and slightly uneven; it is sparsely pubes-
