that a distinctive name should appertain. In one example before 
me the elytral spot extends along the base from close to the 
suture, includes the extreme front of the lateral margin, and 
narrows hindward till it ceases in a sharp point considerably 
behind the middle and a little nearer to the suture than to the 
lateral margin ; the spot in the other example varies inasmuch 
as before it reaches a point it begins to dilate again and then 
spreads out over the whole of the apex. The convexity of this 
species is very similar to that of NV. cardinalis, Muls. 
Queensland ; taken by Mr. Koebele near Toowoomba. 
N. tripustulatus, sp. nov. Breviter late ovalis ; fortiter convexus ; 
nitidus; pubescens; niger, elytrorum macula magna 
humerali et macula communi apicali labro antennis tarsis 
abdomineque (hoc ad basin infuscato) rufis; supra confertim 
subtiliter punctulatus. Long., 12 1.; lat., 1,3, 1. (vix). 
Differs from the preceding species, apart from markings, by its 
still shorter and more convex build and by its closer less fine 
puncturation, which resembles that of WV. simplicipennis ; its 
puncturation is evidently less close and somewhat finer than that 
of NV. cardinalis, Muls. 
N. Queensland ; taken by Mr. Koebele near Cairns. 
N. limbatus, sp. nov. Breviter late ovalis (subcircularis) ; valde 
convexus; pubescens; sanguineus, capite (labro excepto) 
prothorace (lateribus exceptis) et elytris (margine lato 
laterali et apicali excepto) piceis ; supra confertim subtiliter 
punctulato. Long., 14 1.; lat., 1,3, 1. 
Very distinct from the previously described Australian Novi 
by its color and markings. It is a very short, wide, and ex- 
tremely convex species (viewed from the side its height is not 
much less than the length of its elytra). The puncturation of its 
elytra is (for a Novius) decidedly strong, being stronger than in 
any of the preceding three species and slightly stronger than in 
N. cardinalis, Muls., but it is not quite so close as in the last 
named species.

C. concolor, sp. nov. Late ovalis, vix circularis; nitidus; valde

Quite distinct from C. minutus, Blackb., by its entirely black 
color ; also differs in its less circular form and somewhat greater 
convexity. I have before me two examples which differ from
