Palpi as in Promecoderus. Four first joints of anterior tarsi in 

 the males furnished beneath with spongy brushes or cushions. 



It will be seen from this that the last named genus approaches 

 very closely to Promecoderus. 



I find, however, that the labium also difiers somewhat in 

 these genera. In Promecoderus it is subtruncate, but with a 

 prominence in the middle, armed with two long sette. In Adotela, 

 it is quite truncate, while in Cerotalis it is elongate and subemar- 

 g'inate. The labrum also in the two latter genera is more emar- 

 ginate than in Promecoderus. 



The insect described by me in the " Insects of Gayndah " 

 (ante, page 99) as Promecoderus viridis, is undoubtedly an Adotela. 



The following are new species : — 



Promecoderds parvulus. 

 Long. 4| lin. 



Elongatus convexus fusco-niger nitidissimus, thorace ovato 

 canaliculato, elytris angustis subparallelis hand striatis, 

 corpore subtus piceo-nigro nitido, antennis palpis pedibus 

 elytrorumque margine inflexo rufis. 

 This species is abundant enough in the Upper Murrumbidgee 

 country, near Tass. It scarcely difiers, except in size and colour- 

 ing, from the South Australian species, P. gracilis of Grermar. 



Promecoderus Riverine. 

 Long. 6 lin, 

 . Elongatus convexus nigcr nitidus, thorace elongato-ovato 

 canaliculato, elytris angustis baud striatis, antennarum 

 articulo primo palpis coxis tarsisque rufis. 

 As its name implies, this insect inhabits the Lower Murrum- 

 bidgee or Riverina country, and, like the last, closely resembles a 

 South Australian species, P. concolor Germar. It may be readily 

 distinguished from that species by its smaller size and more 

 elongated thorax. 



Promecoderus interruptus. 

 Long. 6 lin. 

 Elongatus convexus niger nitidissimus, thorace subelongato
