Rhyparida. 



This genus is represented by a great many species in 

 Australia, especially in the warmer parts, (^i> and many of 

 them are extremely common. Some of them are almost or 

 quite constant in their colours, some have apparently quite 

 fixed colour varieties, and a few are extremely variable ; in 

 consequence several have been named more than once. On 

 many species, especially amongst the smaller ones, the sides 

 of the prosternum are conspicuously longitudinally striated 

 from base to apex; but the majority are not striated through- 

 out, although very few species are without remnants of 

 striatiori about the base. The antennae vary somewhat in 

 length and thickness, but are seldom of use in distinguishing 

 the species, the second and third joints are sometimes of 

 exactly the same length, sometimes the second and sometimes 

 the third is slightly the longer, but in cases where antennal 

 joints are subequal their apparent proportions are so liable to 

 alteration from the point of view that I have purposely avoided 

 using them. The scutellum also appears to be of very little 

 use in distinguishing species. With the exception of the 

 species of ToTnyris, Cleorina, and ^celodonta, I have referred 

 to the genus all the members of the subfamily now before me, 

 whose four hind tibiae are notched near apex, and have 

 excluded all those whose tibiae are not so notched. The 

 projection behind each notch, and the notches themselves, 

 differ slightly amongst the various species, but the degrees are 

 so slight that they cannot be usefully employed in specific 

 descriptions. All the species here referred to the genus also 

 have regular single rows of elytral punctures ; the punctures 

 frequently diminish in size, or may even vanish posteriorly,, 

 but they are never confused or geminate in arrangement.
