OF NEW ZEALAND. 245 



short, horny in the centre, coriaceous externally, scarcely emarginated 

 in front. Last joint of the labial palpi sub-globular, truncated at the 

 end; that of the maxillary oval. Mandibles very short, sharpened 

 inwardly, without membraneous margin and basal tooth. Labrum . 

 transversely-quadrate, rounded in front, strongly carinated at its base. 

 Antenna gradually thickening to the seventh joint. Legs similar in form 

 to Cytulus. 



433. M. COPUSCans, Pascoe / Ann. Mag. Nat. Hist., September, 

 1875, p. 4. M. ellipticm, valde convexus, nitidissime aeneus, antennis 

 pedibusque pallide ferrugineis ; capite leviter sub-confertim punctato ; 

 prothorace elytrisque coriaceis, subtilissime punctatis ; scutello transversim 

 triangulari, impunctato ; corpore infra ferrugineo, leviter punctato ; femo- 

 ribus tibiisque sparse hirsutis.

Wellington. 



Of this species I have seen only one specimen. It is very like the 

 European M. auratus ; but, inter alia, it is narrower, more minutely 

 punctured, and the scutellum is transverse. 



NOTE. It also occurs at Auckland, where I found one individual 

 only. 



434. M. setarius, n.s. Moderately convex, rather short, sub- 

 globular, obscure piceous, having many erect fuscous setae, legs red, the 

 tarsi yellow, antennae testaceous. There is no perceptible sculpture of 

 any kind, the insect being covered with an exudation, or sappy matter, 

 very difficult to scrape off. The epistome is rounded, and finely but 

 quite distinctly margined in front; labrum transversely carinated behind. 

 The thorax is short, considerably narrowed towards the front, with 

 straight sides ; the elytra are very short, and abruptly deflexed behind ; 

 it is this latter peculiarity, chiefly, which renders the form of the insect 

 so different from M. coruscans ; but, structurally, the two are identical. 



Length, ij line; breadth, almost i line. 



I found one example only at Whangarei Heads. 



435. M. orbicularis, n.s. Very convex, hemispherical, nude and 

 glossy. Head large, moderately closely and coarsely punctate. Pro- 

 thorax large, transversal, narrowed anteriorly, its sides straight and finely 

 margined, the base truncate and of exactly the same width as the 

 elytra; its surface is distinctly but not very closely or coarsely punctured, 

 its punctation very much finer than that of the head. The elytra are 

 finely margined, and their sculpture is more distant and less distinct 

 than that of the thorax. 



The body is of a pitchy-red colour, the legs and antenna are fulvous, 

 the tarsi and palpi clear yellow. 



The scutellum is invisible, and the anterior tibia are not grooved 

 externally. 



A second specimen, which I refer to this species, is quite black and 

 not much shining, with obscure red legs.
