514 NEW SPECIES OF AUSTRALIAN COLEOPTERA, XI., 



Rh^bomela, n.g. 



AntenncB long and filiform. Apical joint of maxillary palpi 

 short and conical. Epipleurse of elytra moderately wide at base, 

 gradually narrowed to apex, flat or gently convex throughout. 

 Intercoxal process of prosternum not conspicuously elevated 

 above the adjacent parts, very wide, base and apex very gently 

 incurved to middle; front coxal cavities widely open behind. 

 Middle tihice strongly curved at base; claws each with a large, 

 suboblong, basal appendix. 



Allied to Phyllocharis and Chalcolampra, but front coxal 

 cavities conspicuously open behind; on those genera, they are 

 closed, although with an oblique suture behind each; the inter- 

 coxal process of the prosternum is wider than in any other Aus. 

 tralian genus of the subfamily. The sexual dififerences of the 

 males are suggestive of many of the Eumolpides. The typical 

 species is R. maculata; a second species is somewhat narrower, 

 and its intercoxal process, although much wider than in any 

 other genus of the subfamily, is slightly longer than wide; its 

 middle tibiae are also not so curiously formed. 



RHiEBOMELA MACULATA, n.sp. (Plate xlviii., fig.6). 



(J. Flavous, prothorax with a median vitta dilated to base, 

 and elytra with ten spots black with a brassy-green gloss, 

 antennae black, tip of apical joint and four basal joints, or parts 

 of same, flavous. 



Head impunctate; clypeal sutures well defined but not deep. 

 Antennae with five basal joints shining and sparsely clothed, the 

 others densely pubescent and somewhat stouter, third and fifth 

 joints slightly longer than the adjacent ones. Prothorax more 

 than twice as wide as long, sides gently rounded, subparallel 

 towards base, hind angles somewhat acute; with rather sparse 

 and small or minute punctures, a few well-defined but not large 

 ones at extreme base. Scutellum subtriangular and impunctate. 

 Elytra distinctly wider than prothorax, shoulders evenly, the 

 sides very gently, rounded; without striation, but with regular 

 rows of not very large but conspicuous punctures, interstices 

 with minute, scattered punctures. Legs moderately long; femora
