Var. macula communi elytrorum nigromaculata, maculis 
lateralibus ad marginem extensa, et macula in margine 
explanato prope apicem addita. Long., 5 1.; lat., 44 1. 
The notable character in this species is the great width of the 
explanate margins of its elytra which at their widest are fully as 
wide as the interval between the suture and the external stria. 
The insect is allied to A. ramulopicta, Wag., from which it differs 
imter alia by the character just cited, by the absence of a yellow 
spot in the front black part of the explanate margin, and by the 
elytra being without any gibbosity behind the scutellum and 
being much less evidently striate. 
N. Queensland ; taken by Mr. Cowley near Cairns; the var. 
taken by Mr. Masters. 
A lauta, sp. nov. Rotundata ; modice convexa ; nitida ; testacea ; 
prothoracis elytrorumque disco plus minusve brunnescent- 
ibus; horum sutura (plus minusve manifeste) et notula 
subsemicirculari (hac ab angulo humerali introrsum curvata, 
in discum paullo extensa et marginem lateralem paullo ante 
apicem attingenti) ferrugineis; elytris pone  scutellum 
fortiter gibbis, aliter ut preecedentis (4. planipennis). Long., 
42 ].; lat., 32 1. 
Owing to the colors of this species being all various shades of 
testaceous or reddish-testaceous they present a washed-out 
appearance which seems constant and characteristic. The only 
marking that is at all well-defined is a ferruginous curved mark 
on the elytra which commences at the humeral angle and curves 
inward (reaching about its middle just on to the discal side of the 
external stria) arriving at the lateral margin again a little before 
the apex. It is distinguished from most of its allies by the 
antennee being constantly unicolorous. The explanate margin of 
the elytra (as in A. planipennis) is at its widest fully as wide as 
the interval between the suture and external stria. 
N. Territory of 8. Australia; near Port Darwin. A N. 
xuinea species (which I have been unable to identify) is near 
this one but has elytra almost impunctulate.
