In my tabulation (vide supra) this species stands beside the 
preceding (S. Cowleyz), but is easily distinguishable from it and 
all its allies by the pale straw color of its prothorax with a basal 
black spot in the form of a triangle with its apex pointing for- 
ward (in some examples the base of the triangle a little dilated 
on each side) ; this spot seems constant. The species is an ex- 
ceptionally pretty one.

S. mareebensis, sp. nov. Sat late ovalis; sat nitidus; pube 
albida densa erecta vestitus ; niger, elytris ad apicem anguste 
rufo-marginatis, capite prothorace (hoc ad basin mediam in- 
fuscato) antennis palpis pedibus abdomineque stramineis ; 
capite sparsius prothorace elytrisque confertim, subtiliter 
punctulatis; prosterno medio longitudinaliter depresso ; 
spatio depresso minus lato antice angustato utrinque subtili- 
ter carinato ; elytrorum sutura postice subtilissime carinata; 
lamellis abdominalibus haud integris. Long., 1 1.; lat., 41. 
In my tabulation of Scymnus this species stands with flavifrons 
and tenebricosus,—differing entirely from both in its coloring, 
from the latter by its larger size, from the former by its finer 
puncturation, &c. It is probable that I have seen only the male 
of this species and that in the female the legs or some of them 
and perhaps the head are darker.

Mareeba in the Cairns District.
