 Long., li 1. ; lat., 1 1. (vix). 

 Yeiy like the common iV. variegata, Macl., but inter alia with- 

 out any pattern on the elytra, much smaller, more elongate, with 

 the prothorax more transverse and less emarginate in front, with 

 anterior angles scarcely at all produced, and having its lateral 

 margins finely serrate. 



South Australia ; near Adelaide. 



PELTONYXA. 



I have before me two species evidently belonging, I think, to 

 this genus, but I cannot identify either of them with the pre- 

 viously recorded P. Deyrollei, Reitt., which is a much larger 

 insect, besides differing in several other particulars. 

 P. australis, sp. nov. Elongata, postice leviter dilatata, minus 

 convexa ; vix pubescens ; ferruginea, elytris dilutioribus, 

 prothoracis disco utrinque (nonnullis exemplis) nigro- 

 umbrato ; capite prothoraceque opacis confertim subtilissime 

 punctulatis ; hoc quam longiori duplo latiori, antrorsum 

 parum angustato, lateribus minus rotundatis minus late 

 reflexis, angulis posticis rotundato-obtusis ; elytris fortiter 

 seriatim punctulatis, interstitiis alternis vixelevatis. Long., 

 Ifl.; lat., fl. 

 South Australia ; Adelaide district. 

 P. pubescens, sp. nov. Elongata, postice leviter dilatata, minus 

 convexa ; pilis erectis sat elongatis vestita ; nigro-brunnea, 

 antennis pedibus et prothoracis elytrorumque lateribus testa- 

 ceis ; capite prothoraceque subtiliter rugulosis ; hoc quam 

 longiori duplo latiori, antrorsum parum angustato, lateribus 

 minus rotundatis sat anguste reflexis, angulis posticis rotun- 

 dato-obtusis ; elytris fortiter rugulose subseriatim punctu- 

 tulatis. Long.,''^lf 1. ; lat., 1 1.

COLYDIID^. 



The determination of the question whether a given insect 

 should be referred to this family or to the Tenebrionidw seems 

 capable of depending merely on the existence or non-existence of 

 a minute basal joint of the anterior four tarsi. By r sax, for in- 

 stance, was originally placed in the Colydiidct^ as having tetramer- 

 ous tarsi, and some years later its author, Mr. Pascoe, rejDorted 

 his having discovered it to be heteromerous, and so transferred it 

 to tlie Tenebvionida'. I draw attention to the close analogy (even 

 if it be no more) between these families, because I have several 

 new species before me for description, which I refer to the
