New Zealand Coleoptera. 93 



Somatidia hehnsi, n. s. 



Parum convexa, elytris dilatatis, ad apicem attenuatis ; 

 thorace parvo, ferrugineo, ad latera nigricante, utrinque 

 tuberculo parvo ; elytris nigro-fuscis, ad basin plaga 

 maxima communi pallide ochracea. Long, 4^^ mm. 



This cm'ious insect, with very sharply defined colora- 

 tion, has the body but little clothed with down, the 

 variegation being caused by tinting of the chitinous 

 substance. The thorax is reddish, with the sides darker, 

 the lateral portions coarsely and closely punctured, the 

 middle less distinctly ; at each side behind the middle is 

 a small but prominent tubercle, and on the disc, just in 

 front of the middle, are two obscure elevations. Elytra 

 narrowed at the base and apex, the greatest width in 

 front of the middle, of a blackish colour, but with a very 

 large and extremely sharply defined pale basal portion. 

 The surface bears numerous coarse but not deep punc- 

 tures ; on the middle of the pale colour there are four 

 obscure elevations, and on the line of junction of the two 

 colours are four other elevations, two on each side like 

 the anterior set, the external being more indistinct than 

 the internal ; the dark posterior portion bears also two 

 small elevations, one in front of the other, on each 

 wing-case. The femora are rather pale at the base, 

 dark at the extremity ; the tibiae are dark at the base, 

 then show a broad pale ring, and their extremity is also 

 pale, as are likewise the tarsi. 



Greymouth, found by Mr. Helms. 



I have much pleasure in naming this interesting little 

 insect after its discoverer.

 nudo rufescente ; antennis variegatis. Long. 7 mm. 



Head very short ; antennal tubercles, placed quite on 

 its upper part, prominent ; granulation of eyes very 

 coarse. Thorax with a transverse depression behind the 

 front, and another at an equal distance before the base ; 

 from the middle of the anterior depression there extends 

 a depression backwards, on each side of which the
