rugicollis, and the two following) by the more curvate sides of the 

 thorax, and the unusually well developed marginal channels, &c. 



Length, 2h ; breadth, 1^ lines. 



Otira Gorge, Canterbury. One example, found by T. F. Cheese- 

 man. 



2308. L. rectipes, '^-s. Nigrescent, head and thoracic margins 

 violaceous, second and third antennal joints, and the tibi®, infuscate, 

 tarsi dark. 



Prothorax broader than long, a little convex and uneven above, 

 rugosely punctate, with hardly any smooth discoidal spaces ; sides 

 slightly curved, their margins well developed, incrassate in front, 

 hind angles rectangular, with a short oblique space between them 

 and the base. Elytra rugosely punctured. Tibice almost straight. 

 Pygidium broadly triangular and rugose-punctate. Antenna- mode- 

 rately elongate. 



The chief differences between this species and its congeners must 

 be sought for in the thoracic angles, form, and sculpture, in the 

 shape of the posterior tibiae, and in the coloration. 



Length, 2^ ; breadth, 1^ line. 



One individual was brought from the Otira Gorge by Mr. T. F. 

 Cheeseman. 



2309. L. calcaratus, '^-s- Shining, violet-coloured, antennae 

 black, femora nearly so, but tinged with violaceous, tibiae and tarsi 

 dark-brown. 



Head indistinctly punctured on the vertex, the antennal eleva- 

 tions less flattened and expanded than usual. Thorax transverse, 

 somewhat uneven and convex, depressed along the front, rugosely 

 punctured, its sculpture irregular ; sides well marginated, thickened 

 in front, a little rounded medially, but with a slight sinuosity before 

 the rectangular and almost protuberant posterior angles, which are 

 separated from the base by a short oblique space. Elytra rugosely 

 punctured, as is also the broad pygidium. Tibiie nearly straight, the 

 anterior with distinct spurs. Antcnnm moderately elongate. 



The rather prominent posterior angles with the sinus in front of 

 each, &c., will lead to the identification of this species. 



Length, 2^ ; breadth, 1|- lines. 



Mount Arthur. T. F. Cheeseman ; a single specimen. 



Note. — This and the five preceding species, as well as No. 1115, 

 form a tolerably homogeneous group or series. They are all more 

 or less metallic and brightly coloured. The elytra are wider than 

 the thorax at the base and still broader behind the middle, there is 

 a depression just inside each shoulder, the extremity is rounded, anti 

 their sculpture is very similar. 



2310. L. princeps, n.s. Elongate, nitid, rufo-violaceous, with 

 a golden tinge on the thorax, antennae and legs nearly black. 



Head nearly smooth behind. Antennce long, three-fourths the 

 length of the body. Thorax much shorter than broad, depressed on
