This species is notable for its deep biack colour and the uniform 
sculpture of its elytra which consists of rows of quadrate im- 
pressions (the impressions becoming gradually and continuously 
smaller from base to apex) the interstices between which are 
narrow, regular, and equal inter se. The type is evidently a 
male. I have a second specimen taken near Adelaide which is, 
no doubt, a female ; it is much larger than the type (long., 9 1. 
but unfortunately its abdomen has been broken off.

NV. semicostata, Blackb. All the observed specimens of this 
insect are, doubtless, males,—assuming that I am right in 
regarding as a male character the presence of spaces on the 
ventral segments conspicuous by their very close puncturation. 
N. Leai, sp. nov. Minus angusta; minus elongata; minus 
nitida ; pilis erectis brunneis et aliis albis (his in elytris 
seriatim fasciculatis) vestita; picea, elytris rufescentibus 
vel potius indeterminate rufo-marmoratis ; antennis sat 
brevibus, modice robustis ; capite vermiculato - inequali 
sparsim punctulato; prothorace in disco levi, ad latera 
rugulose punctulato, sulco longitudinali profundo mediano 
impresso, quam latiori vix longiori ; elytris seriatim punctu- 
latis, puncturis antice magnis foveiformibus retrorsum 
gradatim decrescentibus, interstitiis 5° 7° que plus minusve 
carinatis; tibiis anterioribus 4 arcuatis; abdomine fere levi; 
tarsis (?maris solum) sat elongatis sat gracilibus. Long., 6 1; 
lat., 2 1. (vix). 
Quite incapable of confusion with any other species on account 
of the small fascicles of short white hair with which the elytra 
are ornamented. Both the specimens before me (I take them to 
be two males) are somewhat rubbed so that I hesitate to state 
very confidently the exact disposition of the fascicles, but as far 
as I can make out they run in about four longitudinal rows,— 
about 9 or 10 fascicles in each row, and are very conspicuous. 
This species must bear much general resemblance to Opilo 
jloccosus, Schenkling, but as Herr Schenkling expressly states in 
describing that insect that it has the securiform maxillary palpi 
and bifid tarsal lamelle of an Opzlo, there can of course be no 
more than an accidental likeness.

NV. lugubris, Blackb. I have recently seen examples (males) of 
this species from N.W. Australia.
