be it is difficult to determine. Fabricius gives the locality as 

 Van Diemen's Land; and the specimens in this Museum are 

 all so marked exccjit one labelled New Holland, which 

 generally means West Australia. It is the longest, narrowest 

 species known to me, with the disk of the thorax closely and 

 finely punctured. It is not unlikely this is X. crihricollis of 

 Spinola's Monograph ; certainly his N. porcatus is not the 

 Fabrician species. The Kev. T. Blackburn has given a 

 synopsis of the species of the genus (Tr. Roy. Soc. of 

 8. Austr. xiii. 1890, p 126), and the one he refers to 

 ' N. jwrcatus is evidently not the Fabrician species, as he 

 places it in the section '' Disc of the prolhorax not closely and 

 evenly punctured." The specimens named A", porcatus in 

 White's Catalogue are probably ^;orca<w5 of Spinola (the type 

 was not then in the Museum), and I am inclined to think 

 they are the N. Marstersii^ Casteln,, but it all depends on 

 what this author considered the Fabrician species.

The head is closely and rather finely punctured, with a 

 few much larger punctures interspersed. The antenme are 

 long, the apical joint elongate-ovate, moderately narrowed at 

 the a])cx, the tenth joint as broad as long, the ninth scarcely 

 as broad as long, very obliquely narrowed towards the base. 

 The thorax is as long as broad, not very much flattened on 

 the disk, a little broader at the widest part than in front, the 

 disk very finely, rather closely, but indistinctly punctured ; 

 the sides rugulose, but not strongly as in many of the species. 

 The elytra have the punctures large and transverse at the 

 base, gradually diminishing in size posteriorly, being com- 

 paratively fine at the apex ; the costa? are narrow and equal 

 at the base, the alternate ones disappearing rather before the 

 middle, leaving tiie others separated by dull tlat spaces. The 

 intermediate tibiae are curved. The abdomen has a finely 

 punctured patch in the middle of the second, third, and fourth 

 segments, clothed with golden pubescence, the patch on the 

 fourth segment a little broader than long. Posterior tarsi very 

 lonu'.
