longiori, articulo apicali valde inflato-dilatato; unguiculi 
appendiculati ; cox antice minus elevate, inter se sat longe 
distantes, postice clausz ; mesosternum modicum. 
The species for which I propose this new generic name is of 
great interest because the inflated claw joint of its hind tarsi in 
combination with its closed front cox refer it to M. Lacordaire’s 
Group “ Monoplatites” hitherto (so far as I can ascertain) only 
known as American. I cannot place it in any of the numerous 
previously described genera of the Group. Its maxillary palpi 
do not accord very ‘satisfactorily with those of either of the 
sections into which M. Lacordaire divides the genera by the form 
of the maxillary palpi; the second joint is obconic, the third 
shorter than the second (but not much thicker than its apex) the 
fourth conic and a trifle longer than the second. 
O. Jacoby, sp. nov. Nitida; testaceo-ferruginea, antennis apicem 
versus infuscatis, elytris indeterminate brunneo-maculatis 
horum striis interrupte infuscatis ; capite levi, inter oculos 
transversim arcuatim sulcato; prothorace levi (sulcis 
punctulatis exceptis), angulis anticis manifeste explanatis, 
posticis acutis, lateribus rectis; elytrorum striis apicem 
versus profundioribus, mpeg convexis (apicem versus 
subcostatis). Long., 12 1.; lat., $1. 
The sulcation of the prothorax is unusual, there being an 
extremely strong sulcus running all across in front of the base, 
and also an equally strong longitudinal sulcus on either side run- 
ning from the transverse “sulcus to the base. On the elytra an 
ill defined depression runs hindward just within the humeral 
region and then bends towards the suture which it reaches so as 
to. join its fellow of the other elytron thus causing the inner basal 
part of each elytron to appear elevated. 
N. Queensland ; named in honor of Mr. M. Jacoby well known 
as an accomplished specialist in the Phytophaga. 
SUTREA. 
The following species seem to be referable to this genus which 
has not been previously recorded as Australian, though well 
represented in New Guinea. Its principal characters are ; 
antenne approximate (of 11 joints), front coxal cavities open 
behind, mesosternum normal, hind tibie not sulcate (mucronate 
at apex), anterior four tibice unarmed, claw joint not dilated, pro- 
thorax devoid of impressions, margins of elytra evidently 
dilated.

convexa ; nitida ; testacea, antennis (basi testacea excepta).
