772 REVISION OF THE AMYCTERIDES, iv., 



third interstice with large, prominent tubercles, about ten in num- 

 ber, but variable in both number and position, extending from base 

 down declivity, or ending before declivity; fifth with a continuous 

 row of closely-set tubercles, smaller than on third, rounded at 

 base, conical posteriorly; sixth with a similar row, commencing 

 rather far from base. Sides vertically rugose, tubercles obsolete. 

 Beneath, with a deep, oblique impression on either side of base of 

 median vitta, and fainter impressions on other segments. Anterior 

 femora with a moderately distinct ridge beneath; intermediate 

 tibiae simple. 



9. More ovate; undersurface convex, fifth segment very feebly 

 depressed at apex. 



Dimensions: (J, 14 x 4*5; 9, 15 x6 mm. 



Hab. — Victoria, Melbourne. Type in Macleay Museum. 



Redescribed from specimens in my own collection. This species 

 is very variable in size, and in the degree of tuberculation of the 

 elytra. Some of the specimens I have seen, were hardly larger 

 than S. huhalus, to which the species is most closely allied, but the 

 elytral tubercles are always larger than in that species. 



Two specimens from Caulfield (Melbourne) in the National 

 Museum, Melbourne, differ in having tubercles on the second and 

 fourth interstices; they may belong to a new species; at present, I 

 regard them as a variety. 



SCLERORINUS APICALIS Macl. 



Macleay, loc. cit., p. 260. 



9. Elongate-ovate. Size moderate. Black ; rather densely 

 clothed in depressions with brownish squames; median ventral 

 vitta yellowish. 



Head convex, forehead very feebly bi-impressed in front. Ros- 

 trum rather strongly excavate in front; the external ridges 

 strongly develo])ed, slightly sinuate, the median carina conspicu- 

 ous, rather broader than the external ridges ; sublateral sulci rather 

 narrow, deep. Eyes subrotundate. Prothorax (4-5 x 5 mm.) 

 evenly rounded on sides; subapical and median impressions indefi- 

 nite; closely set with small, rounded granules, rather larger than in
