(Continued from Vol. xxxix., p. 25 2.) 



ScLERORiNus* Macleay. 



Macleay, Trans. Ent. Soc. N. S. Wales, i., 245, 1865. 



Form elongate, subparallel, or elliptical; size moderate to large, 

 female generally larger and more robust than the male; black, 

 elytral tubercles sometimes reddish; clothing variable. 



Head convex, generally separated from rostrum by a feeble 

 transverse impression above, the rostral ridges frequently extend- 

 ing on to the forehead. Rostrum comparatively short, thick, 

 little excavate above ; upper surface bounded by subparallel 

 external ridges; median area not depressed, carinate; sublateral 

 sulci broad, shallow, with deeper basal fovere. Prothorax gener- 

 ally dilate or subdilate on the sides, very little produced above, 

 with well-developed ocuJar lobes ; granulate. Elytra gently 

 rounded on sides, base gently emarginate; disc puncto-striate or 

 foveo-striate ; interstices tuberculate, occasionally subcostate, 

 the alternate interstices sometimes without tubercles. 



^. Ventral surface either (1), maculate, with a median channel 

 on the fifth segment; or (2), with a median hirsute vitta, the fifth 

 segment not depressed. 



* Sderorinus is the original spelling, as it appears in the Transactions of 

 the P]ntomological Society of New iSouth- Wales. In Gemminger and 

 Harold's Catalogue, it appears as Scltrorrhinus, from sclerus=durus, and 

 rhinus— nasus; this spelling has been followed b}'^ Masters, and later by 

 Lea. Although this would be the correct spelling if the derivation be 

 correct, I think that it is by no means certain that Macleay was alluding 

 to the character of the rostrum, and not merely using the termination — 

 inus. The spelling Sclerorhinus^ as used by Pascoe, Sloane, and Black- 

 burn, is in any case erroneous.
