312 NOTES ON AUSTRALIAN COLEOPTERA, 



that segment an uneven appearance. The eyes are like those of 

 Egestria but are a trifle more prominent and more coarsely granu- 

 lated. The antennse (set back) reach beyond the middle of the 

 elytra ; they are filiform, the basal 2 joints being short and of 

 equal length, joint 3 nearly equal 1 + 2, 4 slightly shorter than 3, 

 5 evidently longer than 3, 6 a little stouter than the joints on 

 either side of it and scarcely as long as 5, 7-11 becoming gradually 

 a little longer and a little more slender, 1 1 being very little longer 

 than 5. [It is not improbable that the antennae are different in 

 the other sex.] The prothorax is cordiform scarcely transverse, 

 the base and apical mai-gin being equal or nearly so in width ; its 

 sides are strongly convex in the front portion ; its surface is 

 strongly tuberculate, two rows (each of 3 or 4 elongate compressed 

 tubercles) running down either side of the middle line and 2 or 3 

 smaller and somewhat spine-like tubercles projecting from the 

 lateral margin on either side ; these lateral tubercles are more or 

 less connected by a cariniform line which give the appearance at a 

 casual glance of the prothorax being laterally margined, but on 

 careful examination it is seen that this line is not continuous and 

 is not a true limit between the pronotum and prosternum ; inde- 

 pendently of the tubercles the surface of the prothorax is uneven, 

 the most notable depressions being a wide shallow one down the 

 middle and a large ill-defined circular one on either side near the 

 front. The elytra ai-e rather closely and coarsely punctured and 

 their surface is rendered veiy uneven by a complicated system of 

 carinse and tubercles. The suture is strongly carinated and close 

 to it there is a row of small tubercles ; on either side of the 

 scutellum is a large compressed elongate tubercle and behind the 

 middle of each elytron (nearer to the suture than to the latei'al 

 margin) is a similar but very much larger tubercle in front of 

 which is a much smaller one placed somewhat transversely ; the 

 external half of each elytron bears a number of irregular carinse 

 more or less connected one with another and forming in parts a 

 kind of network, some of which (near the middle of the elytron) 

 are of an ivory-white colour but otherwise not difierent from the 

 rest. The prosternum resembles that of Egestria except in the
