Genera and Species of New Zealand Coleoptera. 107 



There is no other species resembling it. 



Length (rostr. incl.) 3:^, breadth 1^ lines. 



Port Lyttleton. 



One example. Another of Mr. J. J. Walker^s discoveries. 



Platyomida brevicornis, sp. n. 



Piceous, densely clothed with small, depressed, greyish 

 scales •, antennae and tarsi pitchy red. 



Rostrum one fourth shorter than the thorax, with a well- 

 defined central carina. Thorax one fourth broader than 

 long, slightly wider near the front than it is elsewhere, 

 longitudinally depressed along the middle, rugose-granulate. 

 Scutellum transverse. Elytra subovate, broader than thorax 

 at the base, shoulders rather narrow and oblique, sides but 

 little curved ; striate-panctate, third and fifth interstices end 

 behind in nearly equal nodosities ; there are three smaller 

 ones on each side of the posterior declivity, besides some 

 granular elevations. 



This species differs from P. binodes as follows : — The antennae 

 are shorter and thicker, the scape only reaches the middle of 

 the eye, the second joint of the funiculus is just appreciably 

 longer than the first, joints 3 to 7, though longer than broad, 

 are nearly oviform and not at all slender. The thorax is not 

 so rough. The elytra are less uneven above, more narrowed 

 towards the base, and the apices, though not divaricate, are 

 evidently narrower. The eyes are more rotund ate, instead 

 of being decidedly longitudinally oval. The insect, as a 

 whole, is less brightly coloured. 



Length (rostr. incl.) 6, breadth 2^ lines. 



Puysegur Point. 



One from Mr. Saudager's collection, forwarded by 

 Mr. Lewis. 



Obs. — Another, numbered 5194, has the rostrum slightly 

 broader and feebly bisulcate. Elytra broader, with more 

 nodiforra shoulders, their series of punctures more regular 

 and distinct, squamosity more iufuscate. The scape reaches 

 the back of the eye. This insect is probably a varietal form. 



Tigones dispar, sp. n. 



Opaque, subovate, iufuscate red, densely squamose, the 

 squamosity variegate, chiefly fusco-testaceous, with three 

 longitudinal dark streaks on the thorax, and irregular, mostly 

 transverse, dark spaces on the elytra, the setae rather fine, 

 erect, and pale.
