notable fovea?, but on each side close to (lie edge is a very 

 small one; the pygidium is similarly pointed, with an arched 

 sulcus extending along the sides ; tne prosternum has sulci 

 in lieu of stria? similar to those figured for andretvesi (Ann. & 

 Mag. Nat. Hist. ser. 7, vol.xiv. p. 151, pi. vi. fig. 3 a, 15J04) ; 

 the mesostcinum is less shortened than that of andrewesi, 

 but, like it, it has two lateral grooves and a median fovea on 

 the posterior edge ; the inetasternum is conspicuously but not 

 densely punctate, the median canaliculation is narrowed in the 

 middle and somewhat slight ; the anterior tibiae are bidentate.

Nipoiiius interstitialis, sp. n. (PL VIII. fig. 4.) 



Cylindricus, robustus, piceus, nitidus, abdomine rufo-brunneus ; 



tborace baud foveolato ; elytris tenuiter striatis ; propygidio 



4-foveolato ; pygidio profunde bifoveolato. 

 L. 5^ mill. 



Cylindrical, rather robust, piceous, and shining, abdomen 

 and legs reddish brown ; the head finely but rather densely 

 punctate, cephalic armature with two well-marked carina? ; 

 the thorax somewhat reddish at the anterior angles, punctua- 

 tion somewhat dense but of varying sizes, without fovea? ; 

 the elytra, sutural stria is shortened apically but joins 

 the basal margin, the three stripe next the sutural are 

 broken and punctiform and the outer stria? are wanting, the 

 surface is punctulate including the interstices of the striae; 

 the propygidium is wholly punctured and has four fovea?, the 

 cutside ones are largest and circular ; the pygidium has two 

 large lobe-shaped fovea?, and the surface around them i3 

 punctulate ; the prosternum is markedly striate, stria? are 

 feebly sinuous before the coxa?, conspicuously joined p >ste- 

 riorly, and feebly and transversely meeting in front (similar to 

 impressicollis) ; the meso- and metasterna are deeply canalicu- 

 late in the middle, the latter is very finely punctulate; the 

 anterior tibia? are bidentate. 



Bab. Somerset, Australia (M. L. d' Albert is, 1875). 



Niponius untdentatusj sp. n. (PI. VIII. fig. 7.) 



Cylindricus, brunneus, nitidus; tborace baud foveolato; elytris 

 striis obsoletis ; propygidio 4-foveolato ; pygidio bifoveolato ; 

 tibiis anticis unidentatis. 



L. 3 mill. 



Cylindrical, brown, and shining ; the head, cephalic arma- 

 ture obtuse (similar to obtusiceps) , surface somewhat densely
