an example in point, — but I am convinced they will prove to 

 represent a distinct species when more material can be examined. 



H. holomelcenus, Blanch. Long. 5 lines. From Eastern Aus- 

 tralia (already referred to, — vide pp. 1218, 1243). An entirely 

 black insect with the club of the antennae pitchy-red, — closely 

 punctulate. Perhaps near S. rhinastus, Blackb., which however 

 has testaceous antennae. The note as to the unusual colour of 

 the antennae is the only mention of a really marked character 

 in Blanchard's description. 



S. laticollis, Blanch. Long. 5 J lines. From Eastern Australia. 

 The head and prothorax appear to be much wider than in any 

 species known to me and in other respects likely to be identical. 

 The other characters mentioned in the description are all vague. 



H. nigritus, Blanch. Long. 3J lines. From Eastern Australia. 

 A black species with testaceous antennae and palpi, and pitchy or 

 reddish legs ; so far suggestive of nigrinus, Blackb., — but the 

 species as compared with the preceding is said to be "planior" 

 and the elytra are called "fere planis " which seems to remove it 

 far from my nigrinus. 



H. ohlongtcs, Blanch. Long.-4| lines. From Eastern Australia. 

 There is no salient character mentioned in the description of this 

 insect which would apply to not a few of the examples before 

 me ; I cannot identify it with any one in particular. The 

 species appears to be of a brownish-red colour, to have some ashy 

 pubescence, — the prothorax to be very slightly wider than the 

 elytra (if this is strictly correct I am convinced that I have not 

 seen the species) and finely punctulate, — the elytra to be finely 

 punctulate-rugulose, and the pygidium closely punctulate. This 

 is all the information contained in the description. 



H. ovatus, Blanch. Long. 3-4 lines. From Eastern Australia 

 and Tasmania. Notwithstanding its name the form of this species is 

 said to be *' oblongus." The description is almost in the same 

 words as that of H. oblongusj— irom which it appears to differ by 

 being slightly smaller, with less silky pubescence and the prothorax
