Notes on Amycterides. 243 



Tnlauriniia semisp'niosus Bohem. ; T. past ilia >•/' as Bohem. ; 2\ 

 pustidatun Pasc. From Mr. Blaii-'s notes these names apjjeai" to 

 belong to but one species. It is peihaps the connnonest species in 

 Western Australia, and is veiy variable. The type of T . pasfillariu.'i 

 was not examined, this should be in the Stockholm Museum; Init 

 specimens so labelled in the Hope Coll., were considered by Mr. 

 Blair to be conspecific with 7\ setnisj^inosiis. The puncturation of 

 the rostral ridges is fairly close, but not as in T. Roei. The pro- 

 thorax is fairly closely granulate, but is variable in this respect, 

 the median granules, or tubercles, in some specimens being more 

 spaced out and slightly transverse. The elytral tubercles are vari- 

 a,ble in number, and also in size, particularly on the more lateral 

 interstices; as a rule they are of moderate size, and the apical and 

 lateral ones subconical. 



T . simulator Pasc. Compared with the last species T . simulator 

 has the tubercles rounded, shiny, and more .numerous on the fourth 

 and fifth interstices. Specimens identified for me by Mr. Blair 

 have the head and rostral ridges almost impunctate, only a few 

 obsolete punctures being traceable. My specimens came from 

 Kellerberrin, Western Australia. Other specimens from Eucla and 

 Eyre's Sandpatch are smaller and possibly distinct. 



Talaurinus echinops Pasc. Though described as a Sclerorinus, 

 this species is certainly congeneric with T. semis2)inosus. It is a 

 more densely clothed species, with more numerous tubercles. The 

 head and rostral puncturation is much as in T. semispinosus, and 

 the prothoracic granules are small and closely placed. In general 

 appearance it is not unlike T. Roei, but the head and rostrum are 

 in the same plane above, the rostral punctures are different, and 

 the elytral tubeixles are stouter. 



T . validus, n.sp. This species may be distinguished by its strong 

 elytral tubercles, much larger than in T . semispinosus. The punc- 

 tures of the head and rostrum are obsolescent. The prothoiacic 

 tubercles are large and widely separated. 



Talaurinus Leai, n.sp. Close to the last species and with simi- 

 lar strong elytral tubercles, it differs in the more closely punctate 

 head and rostrum, and in the smaller, much more closely placed 

 protTioracic tubercles. 



Talaurinus Westwoodi Bohem. The type of this species was 

 also examined by Mr. Blair, and it proves to be synonymous with 

 T. hucephalus Olivier. 



Talaurinus excavatus Bohem. Mr. Blair has kindly sent out 

 specimens compared with the type in the Hope collection. It is the
