Ilab. New South Wales (Murrurundi). 



Shorter and more convex than P. austrcdis and P. ci- 

 nerea ; the elytra have two callosities at the base, and their 

 sculpture is hidden by the pubescence. Pachyura is perhaps 

 best differentiated from Isacaniha by its short rostrum, gra- 

 dually thicker towards the apex (in Isacantha it is longer and 

 cylindrical), and not by its toothed femora, as Hope put it. 

 In this case my P. jpapidosa should be placed in Isacantha^ 

 with which it otherwise agrees. Lacordaire has united the 

 two genera with Belus, at the same time intimating that JJ. 

 cinereufi, Blanch., should be withdrawn from it; but this is 

 certainly congeneric with aiistralis, the type of Pachyura. 

 Belus itself, having the prothorax and elytra on the same 

 plane, appears to me abundantly distinct from Isacantha and 

 Pachyura, m which either the base (as in the former) or more 

 or less of the dorsum of the elytra is above the line of the 

 prothorax. I am indebted for this and the two following 

 species to Mr. Masters. 



Belus ganglionicus. 

 B. oblongus, sat robustus, rufo-fuscus, supra confertim granulatus, 

 impuuctatus ; prothorace vittis tribus, elytrisque maculiselongatis 

 interruptis prope suturam sitis, e pilis albidis condensatis, notatis, 

 his prothorace manifeste latioribus, lateribus parallolis, apico 

 rotundatis, in mascnlo parum acuminatis ; antennis ( J ) articulo 

 basali quam tertio breviore, ( $ ) brevioribus articulis basali tertio- 

 que subajqualibus, ultimis crassioribus ; corpora infra pilis albidis, 

 medio metasterni et maculis tribus nudis in quoque segmonto ab- 

 dominis cxceptis, dense vestito ; pedibus parcius pilosis. Long, 

 d" 5|, 5 7Iiu. 



Hah. Willoughby Falls, near Sydney. 



A somcAvhat robust and rather depressed form ; in the 

 rounded apex of the elytra (slightly acuminate, however, in 

 the male) it agrees with B. brunncus, Guer. It seems to be a 

 very local species. 



Isacantha exigua. 

 I. oblonga, S cylindrica, subangusta, 5 posticc gradatim latior, for- 

 ruginea, supra confertim granulata, pilis griseis sparse, subtus 

 densius, vestita ; rostro prothorace vix longiore, in focmina paulo 

 breviore, basi crebre piinctato ; antennis subtestaceis, aj|;;ticulo 

 basali longiusculo ; prothorace in medio basin versus canaliculato ; 

 elytris prothorace paulo latioribus, submaculatira pilosis, apice
