POKOPTEROMELA, 11. g. 



Antennae long and thin. Apical joint of maxillary 

 palpi widely securiform, distinctly longer than the preceding 

 one, which is equi-laterally triangular. Prothorax short, 

 apex moderately emarginate and much narrower than base, 

 sides oblique and (as seen from below) in the forms of wide 

 flanges. Elytra very wide, sides strongly rounded, epipleurae 

 very wide and thin, continuing the slopes of the upper- 

 surface. Inter-coxal process of prosternum sloping in front, 

 grooved along middle, base bilobed. Claws each with a strong 

 and acutely-armed basal appendix. 



Owing to the great width of their epipleurae (curiously 

 suggestive of the Gassidides) the elytra are actually wider 

 than long ; they might almost be regarded as a great exag- 

 geration of the concave ones of Paropsis (near which the genus 

 should perhaps be placed), their upper-surface is punctured 

 as the rest of the elytra, and even on the under-surface the 

 pitting is quite evident. I have known the Richmond River 

 specimen for some years, but its general appearance being so 

 very unlike any other Australian Chrysomelid had doubts as 

 to its being really Australian until the sight of the Dorrigo 

 specimen removed those doubts. 



POROPTEROMELA EPIPLEURALI S, 11. Sp. 



Of a dingy livid-flavous throughout. 



Head with dense and fairly-large punctures, becoming 

 smaller towards base. Antennae with third joint almost as 

 long as first and second combined, fourth slightly shorter than 

 "fifth, the others slightly decreasing in length, but eleventh 

 slightly longer than tenth. Prothorax about four times as 

 wide as long, front angles slightly produced; punctures denser 

 and slightly larger than on head. Scntellum subtriangular, 

 impunctate. Elytra distinctly wider than prothorax at base, 

 sides strongly and evenly rounded; strongly convex, with very 

 dense punctures. Lef/s rather thin; first and fourth joints 

 of about equal length. Length, 7-9 mm.

The colour is now as described, but as with so many 

 similarly-coloured ones was probably more or less green in 

 living specimens. Seen from the side, the body appears to 

 be at its greatest height in the middle, this being at about 

 the basal third of elytra ; from this point the elytra appear 

 to slope off in three planes, a somewhat rounded one towards 

 the base, ending on each shoulder, and an almost even 

 plane ending on each margin. The abdomen of the male is
