ferruginea, nonnihil picescens, elytris antennis tarsisque 



dilutioribus ; sat pruinosa ; supra squamis minutis albidis 



sparsim vestita ; subtus squamis minus minutis albidis

elongatis pallide fulvis dense vestitis ; capite crebre

This species is near L. deceptrix, Blackb., and caudata, 



Blackb., but differs from both by its pronotum not margined 



at the base. From caudata it differs also by, inter alia, the 



acute hind angles of its prothorax (which is much more 



strongly narrowed in front) and the very much finer and 



sparser puncturation of its pygidium. From deceptrix it 



differs by its prothorax very evidently more strongly narrowed 



in front and by the finer and much less close puncturation of 



its pronotum (about 20 instead of about 30 punctures in the 



length of the segment). 



Queensland (Port Mackay). 



A. Metasternum pilose. 



B. A well-defined nitid beading all 

 across front of pronotum, and 

 front part of lateral margins of 

 pronotum strongly reflexed and 

 with strong reflexed margins con- 

 tinued round front of angles. 

 C. Base of pronotum with a con- 

 tinuous raised beading preceded 

 by a distinct transverse stria. 

 D. Front angles of pronotum 

 strongly and sharply defined. 

 E. Basal angles of pronotum sub- 



spiniform and divergent ... deceptrix, Blackb.
