366 STUDIES IN AUSTRALIAN ENTOMOLOGY, XV., 



is impossible to know from it even the genus to which it should 

 be referred; its identification would be absolutely impossible 

 were it not that Castelnau in his " Histoire Naturelle des Insectes 

 Coleopteres," I. (p. 105), supplies a clue when he says of his Poecilus 

 marginatus ( = Notonomns marginatus) at the end of the descrip- 

 tion : — " It est voison du P. Kingii Macleay." If we accept this 

 clue it appears to me that we must consider P. kingi W. S. 

 Macleay, to be a species of Notonomns, and judging from the 

 description it should be, in all probability, the species which 

 Chaudoir afterwards named N. incrassalu9, though I do not wish 

 to assume that this suggestion of mine finally settles the 

 question that these two names are synonyms, but it will serve to 

 keep the subject before the minds of other investigators. 



iSToTONOMUS MINIMUS, n.sp. 



Elliptical. Prothorax cordate, posterior marginal seta on 

 border at basal angle; elytra strongly striate, basal border den- 

 tate at shoulders, third interstice bipunctate, eighth interstice 

 narrower than ninth; intercoxal declivity of prosternum flat, of 

 mesosteruum wide, not convex; tarsi with onychium glabrous 

 beneath. Black, legs and antennae piceous-red. 



Head oval, convex (1-8 mm. across eyes), smooth, very feebly 

 bi-impressed between antennae ; eyes (with orbits) reniform, 

 rather prominent. Prothorax convex, cordate, broader than 

 long(2-3 X 2-65mm.), widest before middle; sides lightly rounded, 

 shortly sinuate before base; apex (1-8 mm) narrower than base, 

 (•2-15 mm.); basal angles rectangular with summit obtuse; lateral 

 border narrow, reflexed; median line deeply marked, not reaching 

 base ; lateral basal impressions deep, narrow. Elytra oval 

 (5-2 X 3-3 mm.), lightly and evenly rounded on sides, narrowed to 

 base; apex obsoletely sinuate on each side; striae deep; interstices 

 convex, eighth narrow (narrower than ninth), tenth short (only 

 noticeable just before lateral apical sinuosities). Lengtli 9, 

 breadth 3-3 mm.
