' OF NFAV ZEALAND. 33 



front between antennae, with the joints from the fourth to the eleventh 

 hairy; thorax with a very distinct, transverse, impressed line in front, 

 and at the end of the middle thoracic line ; head and thorax with a 

 greenish hue, strongest on the margins and posterior angles of thorax ; 

 elytra with a very few, scattered, longish hairs ; elytra with a greenish 

 hue, marked similarly to F. australasm ; the sides of elytra somewhat 

 angulated instead of being flat as in that species. 



A species allied to K australasm, but distinguished readily by the 

 size of its head, narrower -thorax, colour, and hairs on elytra ; the insect 

 also is somewhat smaller ; both of these come near the genus Onialosoma 

 of Hope. 



Length, 8?, to gi lines.

68. T. aucklandiCUS, n.s. Smaller, much less convex, and 

 more obscurely coloured than T. autarcticiis, the body above black with 

 a greenish hue, under-side and legs piceous, tarsi and palpi pitchy-red. 

 Head large, with two irregular, elongate frontal depressions united by a 

 transverse line between the antemue, and two or three punctures near 

 each eye. Frotliorax sub-quadrate, rather transverse, widest in front, 

 where the sides are rounded, but behind the middle they are sinuously 

 narrowed towards the distinct rectangular hind angles ; the disc is sub- 

 depressed with an impressed dorsal line, and two curved impressions, 

 one near the front, the other near the base is prolonged so as to unite 

 the two basal fovece. The elytra- are widest behind, very little convex, 

 with tubercular humeral angles, rounded sides, moderately sinuated 

 towards the apex ; each bears an abbreviated scutellar striole, seven 

 discoidal finely punctured stride, and a lateral stria, those nearest the 

 suture are mere lines, but become broader towards the apex ; the inters- 

 tices towards the sides and apex are rather convex, the seventh is bent 

 inwards, so that only the three sutural ones and it reach the apex ; 

 there are four punctures on the third (sometimes only three), five on 

 the seventh, a row near the margin, and the marginal channel becomes 

 widened and rugose posteriorly. The femora are inflated and grooved 

 below, but have not the dentate appearance observable in T. autarc- 

 ticus. The tarsi in my only remaining specimen, a female, are hispid, 

 but not sponge-like below. 



Length, 8^- lines ; breadth, 3. 



I found several specimens some years ago at Auckland, amongst 

 the roots of potatoes.
