Elytra oval (12x6-7 mm.), lightly and widely convex; apical 

 declivity lightly declivous; sides lightly rounded, apical sinuosities 

 strongly developed, wide; stritxj finely but distinctly impressed; 

 interstices flat, discoidal ones subconvex at apical extremity, 

 7th and 8th narrow and convex opposite apical sinuosities, 

 7th flat on basal half, wide, depressed and 3-punctate near 

 apex, 8th about half the width of 7th on basal half, narrower 

 than 9th (except on basal third), 9th rather evenly seriate- 

 punctate; lateral border wide, turning in to base gently and 

 evenly (without any marked curve); basal border not raised 

 above lateral border at their point of junction. Legs long; femora 

 stout, swollen in middle; posterior tibiae long, straight; tarsi as 

 usual in genus, fifth joint non-setulose beneath. Length 21, 

 breadth 6*7 mm. 



Hab.—Yic: Mt. Baw Baw (Coll. French). 



A distinct species, isolated from all others by the following 

 features in combination — large size; elj'tra with fine but distinct 

 striae, eighth interstice narrow ; prosternum with intercoxal 

 declivity flat and furnished with four long seti«. In general 

 appearance it resembles iV. crcesns, Casteln., but differs conspicu- 

 ousl}^ by all the features mentioned above, and b}^ the mandibles 

 being pincer-like, not long and decussating; its facies is that of 

 iV". chalybeus, Dej., but the more strongly striate elytra are in 

 themselves suflicient to distinguish it. 



Following the tabular list of the species of Notonomus previously 

 given by me (these Proceedings, 1902, xxvii. Pt. 2, pp. 256-261), 

 it would follow N. spenceri, and could be tabulated thus : —

Genus S a R t i c u s. 



Sarticus is, strictly speaking, only a subgenus of the huge and 

 universal genus Platysma; but, when treating of local faunas, 

 such subgeneric groups may with advantage be conceded full 

 rank as genera, and in this way it is now used.
