550 Mr. Francis P. Pascoe's Notes on 



the extent, and even the number, of the yellow patches which 

 adorn the elytra of nearly all the species of this genus, are vari- 

 able. The pattern, however, remains pretty nearly the same, and 

 the apical spot, when it occurs in the species, appears to be con- 

 stant in the individual. Thi'oughout the genus, the elytra have 

 always coarse, crowded punctures at the base, which gradually 

 become smaller and more scattered towards the apex, each punc- 

 ture having generally a single hair arising from its base. 



2. Phoracantha polita. 



P. subrobusta, fusca ; prothorace oblongo, quinque-tuberculato, 

 lateribus spinoso ; elytris albis, nitidissimis, fusco-plagiatis, 

 praesertim plaga una basali alteraque apicali, apice bispi- 

 nosis. 



Rockhampton. Sydney. 



Moderately robust, dark brown ; head covered with pale yel- 

 lowish hairs, a narrow impressed line between the eyes ; antennae 

 longer than the body, luteous, with a delicate greyish pubescence, 

 the third to the sixth joint, inclusive, spined ; prothorax oblong, 

 narrowed anteriorly, with five shining tubercles, the posterior pair 

 nearly divided (or otherwise with seven tubercles), the inter- 

 spaces with a fine, somewhat silky, pile, the side with a short, 

 conical spine ; scutellum triangular, with a greyish pubescence ; 

 elytra very gradually narrowing behind, the basal half coarsely 

 punctured, the rest minutely punctured, each with two spines at 

 the apex, ivory white, with dark-brown glossy patches, which are 

 variable in extent, of the two principal, one occupies the whole of 

 the base, except the side, and another the central part from the 

 middle to near the apex, between the two there is a small spot on 

 each elytron, or the two may be joined by a varying line along 

 the suture ; body beneath dark brown, the pectus pubescent, the 

 abdomen smooth and shining ; legs brown, with a delicate greyish 

 pubescence. 



Length 8 lines. 



Apparently coming nearest to Phoracantha trimaculata, Hope, 

 but, so far as I can judge without a comparison of the two, with 

 a more glabrous and differently sculptured prothorax. 



3. Phoracantha pubescens. 

 P. subrobusta piceo-fusca ; prothorace nitido, tuberculato, late- 

 ribus inaequali, mutico ; elytris dimidio basali punctatis, fascia
