Rey. H. Clark on new Australian Phytophaga. 255 
forms arranged under Rthyparida ; but inasmuch as more species seem 
to be required before the question can be satisfactorily cleared up, I 
prefer to leave its decision to Mr. Marshall, who is specially occupied 
with the group, and to register them provisionally under the present 
genus. 
Two examples of M. simplex were taken by Damel in North Au- 
stralia. An example is in Mr. Baly’s collection, and also in my own. 
6. M. rufo-flavus, n. sp. 
M. ovalis, robustus, punctatus, rufo-flavus, subnitidus ; capite inter oculos 
transverse necnon longitudinaliter foveolato; thorace lateribus ad me- 
dium rotundatis et antice attenuatis, transverso, impunctato; scutello 
subtriangulari, levi; elytris robustis, parallelis, brevibus, apice rotun- 
datis, punctato-striatis, punctis post medium obsoletis; corpore subtus, 
pedibus antennisque rufo-flavis. 
Long. corp. 2} lin., lat. 1} lin. 
A single species from the Marquis La Ferté’s collection is labelled 
“ New Holland: ” it is also, I believe, in Mr. Bakewell’s collection 
and that of Mr. Baly. 
7. M. flavus, n. sp. 
M. oblongo-ovalis, parallelus, leviter punctatus, stramineo-flavus, sub- 
nitidus; capite inter oculos longitudinaliter foveolato, impunctato ; tho- 
race latitudine elytris fere eequali, lateribus rotundatis marginatis, im- 
punctato; scutello subcordiformi; elytris parallelis, tenuiter et regu- 
lariter punctato-striatis; corpore subtus, pedibus antennisque flavis, 
genibus antennarumque articulis 6-1]™™™ fuscis. 
Long. corp. 23 lin., lat. 13 lin. 
There is a greater breadth of thorax, and hence a difference of 
facies between this and the preceding species; but as in all other 
respects it agrees with my definition of Marseus, I prefer to deal 
with it as an aberrant form of this group, rather than seek to erect 
it into a separate genus. 
I have received the species from New South Wales.
