versus sat fortiter longitudinaliter sulcatis. [Long. 2, lat. I 5 lines. 
The prothorax is quite twice and a half as wide as it is long 
down the middle; its sides are rather strongly rounded and sinuous 
immediately behind the prominent front angles, which gives them 
a slightly outward direction ; there is a curved impression on 
either side near the lateral mai’gin ; the anterior and posterior 
longitudinal impressions are rather feeble. The pseudo-costse on 
the elytra are little more than very fine lines appearing paler than 
the general colour, and interrupting the puncturation which is 
moderately strong and scarcely tending to a linear arrangement ; 
the lateral sulcus on each elytron is strong, but does not extend 
much beyond the middle. 
A very distinct species. The entirely different colour will at 
once separate it from its Australian congeners.

Supra nitida, cterulea ; subtus cyaneo-nigra, breviter pubescens, 
antennis tibiis tarsisque fusco-piceis ; capite imequali, inter 
antennas longitudinaliter carinato, vix evidenter punctulato ; pro- 
thorace quam longiori paullo latiori, pone medium transversim sat 
fortiter sulcato (sulco margines laterales attingeute), disco vix 
evidenter ad latera sparsim subtiliter punctulato ; scutello Itevi ;

Extremely like the European II. pusiUa, Duf,, from which it 
differs as follows : — the antenme are stouter and (with the tibiie 
and tarsi) are of a more brownish colour ; the prothorax is
