728 NOTES ON AUSTRALIAN COLEOPTERA, 



under the heading " Prosopogmus " a list of all the Feronides of 

 Castelnau of which he has ascertained the types to be lost, and 

 Mr. Masters has included these in the genus Prosopogmus. 



PCECILUS. 



There appears to me to be no satisfactory evidence of the 

 occurrence of any true P melius in Australia, as no author in 

 calling any Australian species by the name has mentioned as 

 present that distinctive character of Poecilus — the basal joint of 

 the antennee carinated. P. Kingi, W. S. Macleay, could not be 

 identified without reference to the type. The descriptions of 

 P. Icevis, Macl., and sulcatulus, Macl., do not read like those of 

 Poecili, and that of P. semiplicatus, Cast., is quite useless. 

 P. chlcunioides, Macl., is stated by its author to resemble P. 

 resp)lendens^ Cast., which is a Chlcenioideus. 



Rhytisternus Bovilli, sp.nov. 



Minus depressus ; piceus, plus minus rafescens ; prothorace 

 quam longiori fere tertia parte latiori, postice utrinque bistriato ; 

 striis in excavatione vix manifesta positis, lateribus postice vix 

 sinuatis, angulis posticis obtusis baud dentatis ; elytris striis 5* 

 6% et 7* plus minus obsoletis ; tarsis posticis extus vix perspicue 

 sulcatis. [Long. 6-6 1, lat. 2^ lines. 



Average specimens of this insect are of a shining pitchy red 

 colour, but I have before me a single example the colour of which 

 is almost uniformly pitchy black. The antennae and legs are fairly 

 robust, resembling those of P. liopleura, Chaud., (and therefore 

 very difierent from those of P. sulcatipies , Blackb.). The frontal 

 sulci diverge strongly behind as in sulcatip)es (in liopleura they are 

 nearly parallel). The prothorax is scarcely so wide in front as at 

 the base (in lioioleura the base is slightly narrower than the front, 

 in sulcatipes the base and front are equal) ; it is nearly a third 

 again as wide as its length down the middle being slightly more 

 transverse than in liopleui'a and sulcatipes ; the sides are a little
