 This very small species is closely allied to both of the pre- 

 ceding two. In shape it resembes gracilis. There are several 

 isolated punctures in front of the centre of the surface of the 

 head. The thorax is still less transverse than that of gracilis, 

 and is more narrowed backwards ; it is depressed all across the 

 base, and is very little wider than the head. The striation of 

 the elytra is scarcely visible outside the sutural stria. In 

 other respects there is little difference from N'. gracilis. 

 Widely distributed in South Australia.

This diminutive species differs from TJienarotes in having the 

 basal joint, as well as the second, third, and fourth, of the 

 anterior tarsi in the male clothed with squamose pilosity, and 

 narrowed at the base. I cannot discover any other structural 

 peculiarity, unless it be that the same joint is not quite so much 

 narrower than the second, as in Thenarotes. The thorax i& 

 rather strongly transverse (quite half again as wide as long), 

 and is nearly truncate both in front and behind, with a faintly 

 marked dorsal channel ; the sides are rather strongly rounded 

 in front (the greatest width being before the middle), and then 

 converge to the base, which is a little narrower than the front 

 margin ; the hind angles are well marked and obtuse ; strictly 

 speaking the basal region is hardly foveolate, but the hind 

 corners of the thorax are explanate ; its surface is quite free 

 from puncturation. The elytra have no sculpture on the disc 

 except a well-marked sutural stria and faint traces of one, two, 

 or three strise beyond it. The blackish markings of the elytra 

 in a brightly coloured specimen consist of a basal triangle with 

 its apex directed backwards on the suture, and a large patch 

 covering the whole of the apical two-thirds of the elytra except 

 a spot on the suture behind the middle. In a pale specimen 

 the basal triangle is reduced in size, and there is a transverse 

 fascia just behind the middle, these markings being fuscous
