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. Lahritm 

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

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

 to Cytuliis.

Wellington. 



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

 European M auratiis ; 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 setag, 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 episiome is rounded, and finely but 

 quite distinctly margined in front; labruni 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 AI. coriiscans ; 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 i)unctation 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 antennce are fulvous, 

 the tarsi and palpi clear yellow. 



The sciitelliini is invisible, and the anterior tibice are not grooved 

 exrernally. 



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

 not much shining, with obscure red legs.
