'284 REVISION OF THE GENUS yOTOXOMUS, 



bordered ; base truncate, sloping forward a little on each side 

 from basal impressions to angles; basal angles rectangular, obtuse 

 at summit ; border narrow, thick, reflexed, not passing basal 

 angles; posterior marginal puncture distant from base in lateral 

 channel; lateral basal impressions long, narrow, turning lightly 

 outward anteriorly. Elytra narrowly oval (11 x 6*5 mm.); base 

 narrow; sides rounded; lateral apical sinuosities strong; basal 

 border strongly raised and obtusely prominent at humeral angles, 

 posterior margin forming an even curve between humeral angles; 

 lateral border narrow, reflexed, very narrow near base ; striae 

 deep; interstices convex, third 2-punctate, ninth convex towards 

 base, tenth not developed. Intercoxal declivity of prosternum 

 narrow and a little rounded in middle; of mesosternum very 

 lightly and widely concave. Legs long; posterior femora long, 

 narrow. Length 17 "5-2 1-5, breadth 5 -5-7 "3 mm. 



Hah. — N.S.W. : Dunoon, Richmond River (Helms), Ourimbah 

 and Narrara (Sloane, in Juty). 



Yar. ? Black ; wider ; prothorax not longer thp-n broad 

 {4-7 X 4-8 mm.); elytra wider and more oval (10*7 x 6-7 mm.). 

 Length 19 mm. This is perhaps a distinct species. 



Hab. — Q. : Wallangarra (W. Kershaw). 



The species to which I have given the name iV. angustibasis 

 is an isolated and very distinct species. It seems, from 

 Chaudoir's description, to be that which he regarded as 

 Neuropates pi^istofiychoides, Motsch., and I have seen it in the 

 Macleay Collection under the name iV. tvilcoxi, Casteln., l)ut it 

 certainly does not agree with Motschulsky's description of Neuro- 

 pates pristonyclwides, nor with Castelnau's description of N. 

 wUcoxi. To my mind Motschulsky's description of JV. pristony- 

 choides is not applicable to any form of N. angustibasis which I 

 have seen, nor have I seen any specimen so small as 7 x 2J lines, 

 nor with three punctures on the third interstice of the elytra; 

 but I identify without misgivings as JV. pristonychoides, Motsch., 

 a Victorian species which I unhesitatingly refer to N. accedens, 

 Chaud., {vide supra, p. 265).
