In the tabulated statement of the distinctive characters 

 of species of this genus in Tr. R.S., S.A., 1906, the follow- 

 ing correction is required; — On page 268, line 48, and 

 269, line 1, for "elytra" read "prothorax." Also transfer 

 the name "ignota, Mad.," from line 3 on page 269 to line 

 49 on page 268.

Heteronyx (continued). 

 Group III. 

 The hitherto published names that can confidently be 

 assigned to species of this group are 17 in number, and there 

 are also 4 species the descriptions of which indicate their 

 place as being in either this or the following group — that is 

 to say, they have the labrum below the level of the clypeus, 

 and antennae of 9 joints, while there is no record of their claw 

 structure. Two of them are Tasmanian species, described by 

 Erickson fprcecox and fempesfivus), which I think I know 

 as members of Group IV., although I have not seen the types. 

 It is worthy of note here that scarcely any Tasmanian Heter- 

 onyces known to me have bifid claws. One of the remaining 

 two (laticeps) was described by Burmeister and attributed to 

 "Australia." I am afraid that laticeps could be identified 

 only by examination of the type, not only through want of 

 information regarding its claws but on account of there being 

 some flaw in the description, the species being said to be some- 

 what larger than "die vorigen art en," while the size is given 

 as smaller than of one of the preceding species, and the word- 

 ing of the comparison seems quite inconsistent with its re- 

 ferring to the immediately preceding H. granum (e./7., the 

 size is given as more than three times that of granum). The
