some of them appearing broader across the base of 

 the elytra ; probably these are males. The granules 

 on the pro thorax are also variable. The third 

 elytral interstice bears a single tubercle abrupt 

 posteriorly, but sloping anteriorly, the interstice 

 being slightly raised but rapidly sinking towards the 

 base ; there are a few obsolete granules at the base 

 of the tubercle. 



235. Tetralophus excursus, Pasc. (?) — South Australia: 



Port Lincoln, Crawler. I attach this name to a 

 species differing from the last, in having a row of 

 granules or small tubercles on the third interstice 

 anterior to the large tubercle, and gradually dis- 

 appearing towards the base. It is named T. 

 excursus in Blackburn's collection. 



236. Tetralojjhus, sp. (?) — Kangaroo Island. Three speci- 



mens from Kangaroo Island perhaps represent a new 

 species. One of them differs rather decidedly in the 

 more granulate prothorax, with the crests farther 

 apart; the other two seem closer to T. elevatus{1) 

 but I am unable to separate them from the first- 

 mentioned specimen. Until more are available I 

 prefer to leave the species undescribed. 



237. Tetralophus sculpturatus , Waterh. — South Australia: 



Lucindale ; Victoria. 



238. Tetralojjhus, sp. (?). — Victoria. A species, differing 



from T. sculpturatus in the smaller number of the 

 elytral tubercles, may prove to be T. incanus, Pasc. 

 or a variety of that species.
