This is not the species recorded by me as S. sordidus MacL, in 

 the Trans. Roy. Soc. South Australia, 1914, p.l 8, but is the same 

 as S. acuminatus Macl. My previous error was due to over- 

 looking the tarsal structure, which at once separates S. sordidus 

 from the previously identified species, which I tentatively regard 

 as a variety of *S'. vittatus. The male is close to *S'. tristis, but 

 has a less asperate structure; the female is distinguished by the 

 non-tuberculate apical ventral segment, the apical margin of 

 which is not bisinuate. 



SCLERORINUS SPENCEI Bohem. 



Bohemann, Schonh., Gen. Cure, vii.(l), 1843, p.64. 



The description of this species shows clearly that it is a 

 Sclerorinus, and also a member of Section i. It is evidently 

 very closely allied to, if not identical with, S. ohliteratus Macl. 

 The apical abdominal segment is described in the following 

 words — "segmento ultimo abdominis apice utrinque emarginato, 

 supra foveola rotunda insculpto." The first part would fit S. 

 ohliteratus^ 'S. i/iornatus, and S. carinatus; the latter part, how- 

 ever, is not an accurate description of any of these species. In 

 S. ohliteratus and S. iriornatus, there is a longitudinal impression 

 leading into a more or less rounded depression at the extreme 

 apex. The following details of description fit *S'. ohliteratus with 

 more or less exactitude — " Thorax , . . . tuberculis et rugulis 

 subremotis, parum elevatis obsitus .... Elytra .... apice 

 dehiscentia, singulatim breviter mucronata, . . . obsolete striato- 

 punctata, .... sutura interstitiisque 2, 4 et 6 magis elevatis, 

 tuberculis par vis, remotis, subconicis, seriatim obsitis, . . . ." 



The description of the eyes as "parvi, subrotundati," and of 

 the rostrum as "... . supra utrinque profunde lateque longi- 

 tudinaliter impressum . . . ," however, is hardly an accurate de- 

 scription of these structures in S. ohliter'atus. At the same time, 

 the description, as a whole, fits S. ohliteratus Macl., much more 

 closely than any other species known to me. 



Among some Amycterides sent to Mr. Lea, some years ago, 

 for examination, from the British Museum, were two males of a 

 species I identified at the time (and I believe correctly), as *S'.
