longitudine sat sequali quam 11"' sat breviori ; capite pro- 

 thoraceque Isevibus; scutello fortiter transverso ; elytris 

 subtiliter sat seqaliter striatis, striis vix perspicue punc- 

 tulatis, interstitiis fere laevibus. Long., 1 1.; lat., f 1. 

 The scarcely visible puncturation of the lateral striae of its 

 elytra separates this species from all its previously described 

 congeners except obtusus, Blackb., from which latter it differs 

 ijiter alia by its very much greater convexity and the ninth joint 

 of its antennae notably shorter as compared with the tenth. Mr. 

 Lea has also forwarded a Fhalacrinus from W. Australia which 

 is extremely close to P. umhratus but apparently distinct, as the 

 apical joint of its antennae is considerably more elongate. It is, 

 however, not in fit condition for description, its elytra being 

 open and the wings exposed, so that its shape cannot be deter- 

 mined.

P. coynis, Blackb. Since describing this species I have met 

 with examples both in Victoria and Tasmania considerably 

 larger than the type, the largest Long., 11 1. 



P. navicularis, sp. nov. Nitidus ; modice, latus ; postice fortiter 

 acuminatus ; antrorsum visus modice convexus ; a latere 

 visus subplanatus; testaceo-brunneus, elytris piceo-umbratis; 

 antennarum articulo 9° fere transverso quam 10""' vix 

 longiori ; 10° transverso ; 11° quam 9° fere duplo longiori ; 

 capite prothoraceque Itevibus ; scutello fortiter transverso ; 

 elytris subtiliter striatis, striis vix perspicue punctulatis ; 

 interstitiis subtilissime punctulatis. Long.,li 1.; lat., 4 1. 

 The elytra of the unique type of this species are almost wholly 

 piceous, a common somewhat diamond-shaped ill defined testace- 

 ous spot being placed behind the suture, and the disc of the pro- 

 thorax also is infuscate. Probably however the infuscation 

 varies. In shape. the species resembles australis, Blackb., but is 

 a little wider and differs inter alia by the absence of distinct 

 punctures in its elytral striae, and by the apical joints of its 

 antennae, the ninth joint in anstralis being evidently longer than 

 wide, evidently longer than the tenth (which however is scarcely 

 transverse), and scarcely shorter than the eleventh.

The following table shows characters by which the described 

 species of Phalacrinus may be distinguished inter se : — 



A. Lateral striae of elytra very much more deeply 



impressed than in the other species ... ... notabilis, Blackb. 



AA. Lateral strice of elytra normal. 



B. Lateral striae of elytra very distinctly punctulate 

 C. Form nearly circular, — obtuse behind. 



D. Form (viewed from in front) extremely 



convex (compressed) ... ... ... compvessus, Blackb.
