448 Mr. A. M. Lea's Notes on 



Head flattened ; with dense, large, round, shallow punctures, on 

 the middle of the vertex sparser, and (although not larger) more 

 distinct. Antennce very short, scarcely longer than the width of 

 the head. Prothorax much less than twice as wide as long, disc 

 strongly gibbous and with a rather narrow ridge on each side of 

 tlie middle, at the sides of these a feeble ridge, between these and 

 sides a small obtuse tubercle ; sides serrate ; irregularly punctate 

 but with large and almost regular punctures margining the base 

 apex and sides ; base strongly produced backwards ; anterior angles 

 strongly rounded and much below the level of base. Scntellum 

 strongly transverse, flat, level with suture, apex much wider than 

 base, sides incurved to base. Elytra suboblong, strongly convex, 

 shoulders strongly produced, subhumeral lobes deep, suture finely 

 serrate ; disc very irregularly elevated and with large foveate 

 punctures much interrupted by the elevations. Pt/gidium with 

 large punctures irregularly distributed and with a continuous dis- 

 tinct, narrow median carina. Under-surface and legs with punctures 

 much as on head. Intercoxal process of prosternum funnel-shaped, 

 the top of the funnel acting as a chin-piece ; process of mesosternum 

 deeply notched in fi'ont. Abdomen large, the first segment large 

 at sides small in middle, second, third and fourth narrow and semi- 

 circular, fifth large, with a wide and rather shallow fovea having 

 wide lateral extensions. Tarsi very short and wide, the claws almost 

 resting on the third joint. 



Length 4 mm. 



Jflah. Queensland: Cleveland Bay (type in Macleay 

 Museum). 



The elytra are very roughly sculptured, seen from above 

 the sides appear to be incurved, there is a large granulate 

 tubercle on each in the middle of the base, each also has 

 a narrow very irregular strongly elevated ridge (witli 

 numerous offshoots) running obliquely from the shoulder 

 to beyond the middle, whence it curves outwards. Owing 

 to its extensions the apical fovea at first glance appears 

 as if widely transverse. In the type only one antenna 

 is perfect and at present is resting in a prosternal groove 

 (much as in many Elatcridas) , and as the specimen is not 

 my own I have not cared to risk breaking it to examine 

 and figure the joints. The prothorax produced at the 

 middle of the base with the strongly elevated disc are 

 reminiscent of certain plant bugs of the family Memhracidm. 

 The shape of the scutellum and many other unusual 

 features combine to render this the most distinct Australian
