 The front tibiae passing gradually at the apex into the niucro, 

 which thus becomes a continuation of the tibiae, will distinguish 

 this genus, I think, from all the other Australian Erirhiniw 

 except O^nocliroma from which it differs inter alia by the much 

 shorter basal joints of its tarsi. 



hirsiUus, sp. no v. Sat brevis : rufus vel rufo-testaceus, rostri 

 apice summo nigro; squamis concoloribus et nonnullis albidis 

 intermixtis (his plus minusve distincte vittatim in pro- 

 thorace elytrisque condensatis) totus densissime vestitus et 

 capillis erectis valde elongatis (alteris albis alteris nigris) 

 instructus ; rostro quam prothorax (maris vix, femime 

 manifeste) longiori, sat robusto, parum arcuato, supra 

 reticulatim strigato ; antennis modice elongatis, funiculi 

 articulis basalibus 2 elongatis ceteris brevibus inter se sat 

 Bequalibus ; prothorace crebre sublongitudinaliter ruguloso- 

 punctulato ; elytris quam jorothorax multo latioribus, leviter 

 striatis, striis puncturis sat magnis (his minus crebre 

 dispositis) impressis, interstitiis vix convexis, humeris 

 obtusis. Long, (rostr. inch), 2i^l.; lat., 1 1. 

 The facies of this insect is much like that of Nedyleda (as 

 figured in Journ. Linn. Soc, 1872, t. 12, fig. 9), but the sides of 

 its elytra are less rounded. The rostrum is much like that of a 

 Rhachiodes (e.g., R. granuUfh\ Chev.), although that of the male 

 is shorter than of any male RhacJiiodf^s known to me. The 

 vestiture is much like that of Olanaa^ but the erect hairs are 

 much longer than in any Olancea that I have seen. The tarsi 

 are like those of De^iantlta, except in the claws not being divaric- 

 ate. The squamosity is so dense as entirely to hide the sculp- 

 ture, which I have descriljed from an abraded specimen.
