denticulatse, apice mucronatse; tarsorum articulus ultimus sat 

 exsertus ; unguiculi divergentes ; abdominis segmenta S"^"^ et 

 4^*™ conjuncta 2° breviora ; suturse ventrales baud ad latera 

 angulatse, 1^ arcuata ; prostei'num antice sat elongatum sat 

 fortiter emarginatum, baud canaliculatum. 



Tbe combination of connivent rostral scrobes with an antennal 

 funicle not longer than the scape, having its 2nd joint much 

 nearer in shape and size to the 3rd than to the 1st, will I think 

 separate this genus from all previously described Australian 

 Erirhinides. The scales are coarse and very flatly adpressed, so 

 that they are little conspicuous, and have rather the appearance 

 of patches of some extraneous indumentum. 



Symbothynus squalidus, sp.nov. 



Elongatus, piceus, elytris umbrinis vel ferrugineo-umbrinis, 

 antennis pedibusque obscure rufescentibus, abdomine postice 

 rufo ; subtus squamis albis dense, supra squamis obscuris et 

 nonnullis albis, vestitus ; setulis bi-evibus suberectis sparsim 

 instructus ; rostro prothorace paullo longiori ; hoc parum 

 transverse, crebre sat fortiter rugulose punctulato, lateribus 

 sat rotundatis ; elytris sat fortiter punctulato-striatis, inter- 

 stitiis vix convexis ; corpore subtus crebre sat fortiter sub- 

 rugulose punctulato. [Long. 2, lat. 5 line. 



The derm on the undersurface in fresh specimens is almost 

 completely concealed by scales ; my description of its colour 

 therefore is only of a single example which I have denuded, and 

 this may be variable, but if not the red apical 3 ventral segments 

 are a conspicuous character. On the upper surface the scales are 

 of a kind of neutral tint, with the exception of a white line down 

 tlie middle of the prothorax, a small white blotcli on each shoulder, 

 white scales on the scutellum, and a variable and irregular pro- 

 jection here and there of the white scales of the undersurface on 

 the sides of the prothorax and elytra.
