The general appearance of both sexes is close to that of 

 robiistus, but it may be at once distinguished from that 

 species by the suture. In robiistus the suture at the summit 

 of the posterior declivity is considerably thickened, and sup- 

 plied with numerous granules or small tubercles; in the pre- 

 sent species the suture there is entirely without granules or 

 tubercles. The median groove of the rostrum is deeper than 

 in rob ust us, and there are some minor distinctions. I had 

 specimens of this species, and there are others in the Macleay 

 Museum labelled as hypocritus, but as they did not agree with 

 the description some were sent to Mr. Arrow for comparison 

 with the type of that species, and of them he wrote: "Your 

 Leptops is entirely different from L . hypocritus, which is 

 smaller, with shorter and more rotund elytra, and completely 

 covered with green or grey scales. The pronotum is scarcely 

 wrinkled, but has a slight median canal in its anterior part 

 only." In my table it would be associated with cicatricosus- 

 and setosus, to neither of which is it at all close. The scales, 

 except the indistinct black ones, are more or less uniformly 

 coloured throughout, on most specimens being of a more or 

 less ashen-grey, but on several distinctly golden, sometimes 

 with a rosy gloss, but not one of the numerous typical speci- 

 mens has them green. They are sparse or absent from most 

 of the elevated parts, so that, to the naked eye, the prothorax 

 appears feebly striped, and the elytra conspicuously so. The 

 tubercles on the odd interstices are small and obtuse, and 

 cause them to appear like undulating ridges; they all 

 terminate slightly below the summit of the posterior declivity. 

 On the fifth they commence near the basal fifth, on the others, 

 at the base ; near the base of the seventh there is a subconical 

 one, larger than any of the others, but not very large. 



Mr. Curnow informs me that the species is responsible 

 for the destruction of many apple-trees by the larvae eating the 

 roots, apparently in much the same way as the larvae of 

 robustus and squalidns (hopei) do. 



Stenocorynus variabilis, Blackb. (formerly Lipothyrea). 



This species was doubtfully referred to Lipothyrea by the 

 late Rev. T. Blackburn, but it is a Stenocorynus. The 

 original generic diagnosis of Lipothyrea is very faulty, and 

 the genus will probably find a resting place in the

Stenocorynus subfasciatus, Pasc. (formerly Leptops). 

 S. ner/lectus, Lea. 

 Mr. Arrow has kindly sent a co-type of Leptops sub- 

 fasciatus, Pasc. It is certainly a Stenocorynus, and is the
