This species stands in my tabulation beside §. parallelus, 
Blackb., which it closely resembles, differing from it chiefly in 
the much stronger puncturation (and much more strongly 
rounded sides) of its prothorax. Both these species bear much 
resemblance to the insect which I have called Midus (1) pygmeus 
but are at once separated from it inter alia by their first ventral 
suture being almost entirely effaced in the middle.

At once distinguishable from all its previously described Aus- 
tralian congeners inter alia by its coloring. NV. ruber, Blackb., 
the only one of them having unicolorous red elytra, has head, 
prothorax, and legs also red, and is differently punctured.

N. discoidalis, sp. nov. Breviter late ovalis; sat convexus ; 
nitidus ; pubescens; niger, elytrorum macula magna basin 
attingenti labro antennis tarsis abdomineque (hoc ad basin 
infuscato) brunneo-rufis; supra subtilissime sat crebre 
punctulatus. 
Var. elytrorum macula ad apicem continua. Long., 12 1.; lat.,

More like the preceding than any other previously described 
Australian Novius, but I do not think it possibly an extreme 
var. of that species since, apart from its having very distinct 
elytral markings, it is a larger, broader, and more convex insect 
with elytral puncturation certainly both finer and less close. 
Even should it prove to be merely a form of a very variable 
species it seems to be a form to which it would be convenient
