■94 NOTES ON AUSTRALIAN COLEOPTERA, 



insect, and is stated to have its elytra striated as R. liopleura, 

 whereas the elytra of the present species are striated very 

 differently, the enfeeblement of the striae 5-7 being limited to the 

 anterior part, so that in more than the apical ^ part of the elytra 

 the striation is nearly regular and even. Ji. sulcatipes, Blackb., 

 has the slightest suspicion of iridescence, but it also differs inter 

 alia in much larger size and in the very much more extensive 

 enfeeblement of the 5th-7th elytral striae. I notice that in this 

 species the strigosity of the prosternal episterna is exceptionally 

 strong, and is even extended a little on the middle part of the 

 prosternum.

This species is distinguished from nearly all its described 

 ■congeners by its prothorax being much narrower across the base 

 than across its front margin, and the sides of the same being 

 quite strongly sinuate in their hinder part. It is perhaps nearest 

 to R. puella, Chaud., but in that species inter alia the hind angles 

 of the prothorax are said to be right angles.
