less strongly marked than the second) is less enfeebled in the 
middle than in most Australian Scymni. 
N. Queensland ; taken by Mr. Koebele near Cairns. 
S. ambulans, sp. nov. Sat late ovalis; modice convexus ; sat 
nitidus; pube albida erecta vestitus; brunneo-testaceus, 
elytris totis piceo-nigris, prothorace sternorum parte mediana 
femoribusque plus minusve infuscatis ; capite sparsius dis- 
tincte, prothorace elytrisque vix distincte, punctulatis ; 
prosterno medio longitudinaliter depresso, spatio depresso 
minus lato antice angustato utrinque subtiliter carinato ; 
elytrorum sutura vix manifeste prope apicem carinata ; 
lamellis abdominalibus integris. Long., 14 1.; lat., 11. (vix). 
In my tabulation of Scymnus this species stands beside vagans, 
Blackb., with which its very much larger size renders it quite 
incapable of confusion. The first ventral suture is less enfeebled 
in the middle than in most Australian Scymnz. 
N.S. Wales (Blue Mountains) and Queensland (Moreton Bay); 
taken by Mr. Koebele. 
S. varipes, Blackb. Sat late ovalis ; modice convexus; sat 
nitidus; pube fulvescenti erecta vestitus; niger, capite 
prothoracis angulis anticis summis antennis palpis tibiis, 
anticis tarsis omnibus abdomineque testaceis, tibiis iuter- 
mediis rufescentibus; capite crebrius subtilius, protho- 
race elytrisque vix distincte, punctulatis ; prosterno medio 
longitudinaliter depresso, spatio depresso minus lato antice 
sat angustato utrinque subtiliter carinato; elytrorum sutura 
postice subtiliter carinata ; lamellis abdominalibus integris. 
Long., 12.1.5 lat., 141. 
Stands in my tabulation with the preceding and S. vagans,— 
differing from both inter alia by its larger size, and its undersur- 
face black except the testaceous abdomen. The first ventral 
suture is less enfeebled in the middle than in most Australian 
Scynvn. 
This is the insect formerly mentioned by me as Scymnodes 
varipes (2 var. of S. Koebelez). It has not however the antenne or 
the metasternal lamellz (both, in my opinion, essential characters) 
of Platyomus (Scymnodes) but of Scymnus and therefore not- 
withstanding its general facies of Platyomuws I have no hesitation 
in placing it in Scymnus. I regret that when I formerly men- 
tioned this insect I had not observed the form of the metasternal 
lamelle in Platyomus (a character that seems to have escaped the 
notice of other authors also) and so erroneously referred this in- 
sect to that genus. 
Queensland; taken by Mr. Koebele near Toowoomba on 
Hugenia.
