allied to H. capitalis, from which it differs by, inter alia, its 

 prothorax widest at the middle, its elytral puncturation 

 asperate, etc. It, and the preceding two species, in the tabu- 

 lation (Trans. Roy. Soc, S.A., 1909, p. 48) follow pygidialis, 

 thus : — 



BBB. Clypeus raised into a narrow erect 

 lamina in front. 

 C. Clypeal lamina with parallel sides; 



puncturation coarse and sparse ... cornutus, Blackb. 

 CC. Clypeal lamina more or less fan- 

 shaped ; puncturation fine and close. 

 D. Basal 2 joints of intermediate 



tarsi subequal capitalis, Blackb. 



T>T>. Basal joint of intermediate 

 tarsi very much longer than 2nd 

 joint pedarius, Blackb. 



North- Western Australia (Mr. Masters). 



The number of names under which species have been 

 described as Heteronyces, or which there is reason to attribute 

 to the genus, although differently placed by their authors, 

 is, I think, 328, including the new species described in this 

 present Memoir. Of these names 293 will be found in the tabula- 

 tions above (161 as previously described species, 131 as new 

 species). The 35 names omitted from tabulation are accounted 

 for as follows : — 



Synonyms (10), viz.: — 



australis (Cotidia), Boisd. (nom. prceocc.)—fallax, 



Blackb. 

 breviceps, Blackb. = rufopiceus, Ma-cl. 

 fissiceps, ~Bla,ckb. = chlorotica, Gyll. 

 hepaticus, Er . = fumatus , Er. (vide Trans. Roy. Soc, 



S.A., 1901, p. 22). 

 obscurus, Le Guill. — nigellus, Er. 

 pubescens, Macl. =Erichsoni, Blackb. 

 rapax, Blackb. = fumatus, Er. 

 Coivelli, Blackb. = concolor, Macl. 

 submetallicus, Blackb. — Lindi, Blackb. 

 subvittatus, Macl. = sub f 'us cus, Macl. 

 Subsequently made the type of a new genus (1), viz. : — 



baldiensis, Blackb. ( Pseudoheteronyx ) . 

 Species unknown to me, and not sufficiently described for 

 confident identification (21). It seems desirable to furnish 

 notes on these separately. They are : — 



rotundiceps, Blanch, (already discussed under Group 



i.). 



Spadiceus, Burm. (already discussed under Groups 

 I. and VI.).
