740 COLEOPTERA 



seven interstices are a little elevated behind, are merged in the apical 

 margins, and studded with minute tubercles ; similar but smaller projec- 

 tions occur along the sides and posterior slope also, but are not readily 

 noticed. Legs clothed with yellow hairs. Prostemuvi coarsely and 

 densely sculptured and hairy, the rest of the breast remotely punctured ; 

 the 7netastcrnum with an abbreviated groove behind. The abdo??ien is 

 coarsely punctured ; the third and fourth, and base of the ventral one, 

 however, quite smooth. 



Length, nearly 2 lines ; breadth, nearly |. 



The species is evidently rare. It was discovered near Wellington by 

 Mr. P. Stewart. 



Homarus. 



Nov. gen. 



Body cylindrical, squamose. Head vertical in front, with a qua- 

 drangular muzzle. Eyes narrow, transverse, remote, distinctly facetted. 

 Antennas short ; scape as long as funiculus, gradually incrassated ; funi- 

 culus 6-articulate (.''); first joint stout, sub-globular; joints 2-6 small, 

 compact, gradually widened, second obconical ; club pubescent, oval, tri- 

 articulate, the terminal joint rather long and somewhat pointed. Pro- 

 thorax sub-quadrate, slightly narrowed anteriorly, its base truncate. 

 Scutelluvi distinct. Elytra cylindric, a little broader than thorax, mode- 

 rately declivous posteriorly, individually obtusely rounded, slightly raised 

 and crenulated, and overlapping the base of the thorax. Legs stout ; 

 femora dilated ; tibioi expanded apically, dentate externally, considerably 

 produced inwardly at the extremity ; tarsi stout, their three basal joints 

 about equal, third almost bilobed, fourth as long as the preceding three 

 conjointly ; claivs stout, thickened at the base. Prostertium plane, 

 depressed between the broadly separated anterior coxa3, these latter pro- 

 minent; mcsosternum short, depressed, middle coxae more distant than 

 the front pair ; mctastcrnuvi moderate, a little elevated, posterior coxae 

 least remote. Abdoinen not twice the length of the metasternum, its 

 basal segment as long as the three following short ones, their sutures 

 distinct ; its process produced between the cox^e. 



13 1 3. H. mundulus, n.s. Cylindric, slightly glossy, pale casta- 

 neous ; antennal club infuscate. 



Head finely sculptured and clothed. Prothorax about as long as 

 broad, but little narrowed towards the front where it is slightly con- 

 stricted, very obsoletely carinated on the middle, moderately punctured, 

 and clothed with fine yellowish scales. Scutellum depressed. Elytra a 

 little broader than thorax, not abruptly deflexed behind, each rounded 

 and slightly raised at the base, and at that part blackish and crenulate ; 

 they are rather coarsely punctate-striate, with punctulate interstices 

 covered with fine yellowish scales and erect pallid setae. Tibics. elongate- 

 triangular, denticulated on the outer edge. Under-side testaceous, punc- 

 tate, clothed with greyish hairs. Anterior coxcb prominent, nearly vertical 

 inwardly, leaving a very obvious space between them. Metasternum 

 canaliculate. 



Length, i line ; breadth, \. 



I found three examples near Whangarei Harbour.
