Head with very dense, subasperate punctures. Antennae 

 not very thin, scarcely passing hind coxae. Frofhorax scarcely 

 wider at base than at apex, sides evenly rounded, with a 

 shallow depression along middle, and a very shallow transverse 

 one, scarcely traceable across middle ; with very dense but 

 well-defined punctures, each with a small central pit. Elytra 

 roughly granulate-punctate, especially about base, and with 

 remnants of striation. Abdomen strongly upcurved at apex, 

 and with a shallow depression before same. Length, 5J mm. 



Hah. — New South Wales ; Clyde River. Type in Macleay 

 JVIuseum. 



The prothoracic punctures, although crowded, are con- 

 siderably larger than usual, each is more or less circular in 

 outline, with short vertical walls and a central pit; somewhat 

 similar ones are to be seen in other species — e.r/., rasa, obsc-ura, 

 elef/aiifida, viridis, etc. — but being much smaller and shallower 

 their sculpture is much less conspicuous than on the present 

 species. The elytra, about the base, are also more roughly 

 sculptured than is usual. The tibial notches are elongated and 

 very ill-defined, those of the hind pair particularly so. In 

 general appearance it is somewhat like a rough purplish rasa, 

 but the prothoracic punctures are more than twice the size of 

 those of that species, and the tibial notches are much more 

 feeble. The transverse prothoracic depression is very feeble, 

 but as it is traceable the species has been referred to A A of the 

 table ; if regarded as belonging to A, it could be readily dis- 

 tinguished from all the species of that group by the prothoracic 

 punctures and elytral clothing ; the latter, although short, is 

 not depressed, and when viewed from behind appears to be in 

 almost regular rows ; it is a trifle longer at the base than else- 

 where, but there are no hairs conspicuously longer than others. 



Edusa. 



Tliis genus was formally diagnosed by Chapuis in 1874, 

 and divided by him into three subgenera. Blackburn in 

 1891 wrote, ''I do not think that this subdivision can be 

 maintained, at any rate unless a number of other subgenera 

 be added," and certainly he referred to Edusa species (such 

 as sinyidaris,^^^) glabra, and anf/ustulaj that could not be cor- 

 rectly referred to any of the three. 



Regarding chrysura as the typical species, the features 

 regarded as generic so gradually change that it is difficult to 

 indicate dividing lines between subgenera. That the genus 

 wall be eventually again split up is almost certain, but I 



(68) Now referred to Geloptera.
