obtuse elevato instructis, in medio albido nebulosis, ad apicern 

 grisescentibus ; femoribus dente parvo spiniformi armatis. Long.

Hob. New South Wales (Murrumndi). 



Shorter and more convex than P. australis 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 Isacantha 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. papulosa should be placed in Isacantha, 

 with which it otherwise agrees. Lacordaire has united the 

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

 cinereus, Blanch., should be withdrawn from it; but this is 

 certainly congeneric with australis, the type of Pachyura. 

 Belus itself, having the prothorax and elytra on the same 

 plane, appears to me abundantly distinct from Isacantha and 

 Pachyura, in 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, 

 impunctatus ; protborace vittis tribus, elytrisque maculis elongatis 

 intcrruptis prope suturam sitis, e pilis albidis eondensatis, notatis, 

 his protborace manifeste latioribus, lateribus parallelis, apico 

 rotundatis, in masculo parum acuminatis ; antennis ( <5 ) articulo 

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

 que subsequalibus, ultimis crassioribus ; corpore infra pilis albidis, 

 medio metasterni et maculis tribus nudis in quoque segmento ab- 

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

Hob. Willoughby Falls, near Sydney. 



A somewhat robust and rather depressed form ; in the 

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

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

 very local species. 



Isacantha exigua. 



I. oblonga, J cylindrica, subangusta, $ postice gradatim latior, fer- 

 ruginea, supra confertim granulata, pilis griseis sparse, subtus

 basah' longiusculo ; prothorace in medio basin versus canaliculate ;
