75. Thotmus halli sp. nov. 



Subovate, moderately convex, without superficial inecjualities, derm 

 subopaque, pale rufo - castaneous, covered with thin depressed incon- 

 spicuous obscure greyish squamae, and also bearing numerous suberect 

 grey setae. 



Rostrum with a median linear impression. Head moderately convex. 

 Thorax a third broader than long, apex feebly emarginate, widest near the 

 middle, rather more abruptly narrowed behind than in front, on a care- 

 fully denuded spot finely and distantly punctured. Elytra more than 

 double the length of the thorax, nearly vertical behind ; each, at the base, 

 oblique towards the suture, and consequently not closely applied to the 

 thorax ; they are rather finely punctate-striate. Legs thickly clothed with 

 grey setae. 



Underside reddish-chestnut, with grey setae. 



Length (rostrum inclusive), 13 mm. ; breadth, 6| mm. 



Pitt" Island. 



Named in honour of its discoverer, Mr. T. Hall. The specimen is unique 

 and somewhat immature ; perfect examples probably will be darker. It 

 is, I have no doubt, an inhabitant of the sea-shore, where it should be 

 sought for. 



Platyomida White. Man. N.Z. Coleopt., p. 441. 



76. Platyomida versicolor sp. nov. 



Subopaque, nigrescent ; covered with depressed tawny squamae, which, 

 however, are intermingled with a few metallic cupreous and viridescent 

 ones ; these are most apparent when the insect has been brushed with 

 benzine ; there are also some obscure yellowish setae on the elevated and 

 posterior parts of the elytra ; antennae and tarsi piceo-rufous. 



Rostrum nearly as long as thorax, with a median carina separating 

 the broad longitudinal grooves and terminating in the interocular fovea. 

 Thorax as broad as it is long, slightly broader before the middle than else- 

 where, base and apex subtruncate ; the surface somewhat uneven, with 

 slightly rugose tubercular sculpture and a rather broad irregular channel 

 along the middle. Scutellum normal. Elytra broader than thorax at the 

 base, wider near the middle, a good deal narrowed posteriorly ; disc nearly 

 plane, striate-punctate, 3rd and 5th interstices slightly nodiform at the 

 top of the posterior declivity, in the female slightly and unevenly elevated 

 throughout. 



Underside blackish, the squamae of a more metallic lustre and more 

 brightly coloured than those above. Prosternum incurved. Basal ventral 

 segment evidently longer than 2nd, subtruncate between the coxae ; 5th as 

 long as the 3rd and 4th combined. 



Scape minutely squamose, gradually thickened, attaining the back of 

 the eye ; 2nd joint of funiculus as long as the basal ; club minutely pubes- 

 cent, almost as long as joints 4-7 of the funiculus taken together. 



Ocular lobes feebly developed. Posterior corbels with duplicate ciliae 

 and a narrow external truncature. 



Male. — Elytra elongate- oviform, and only slightly broader than thorax 

 at the base ; legs longer, more slender and flexuous. When compared 

 with the same sex of the common P. binodes, 776, of New Zealand, the
