PSEUDOCLITHRIA RUGOSA, Schaum. 



Referred to Diaphonia (as a subgenus of Schizorrhina) 

 by Schaum, by Kraatz to Metallesthes. It is a short, compact 

 species that appears best placed with hirticeps, and so I refer 

 it to Pseudoclithria. The only specimens before me are two 

 males belonging to the National Museum, Melbourne, and 

 Mr. C. French. 



Pseudoclithria maura, Janson. 



As noted by Janson this species is very closely related 

 to rugosa, and I therefore refer it to Pseudoclithria. The only 

 specimens before me are two males from Western Australia 

 belonging to Mr. French and Mr. Griffith (the latter from 

 Perth). 



Pseudoclithria adusta, Janson. 



This species is also transferred to Pseudoclithria, as 

 Janson's description renders it quite evident that it is, as 

 stated by him, closely allied to rugosa. 



Pseudoclithria ruficornis, \Vestw. 

 PI. xiii., figs. 173, 174, 175. 



Somewhat doubtfully I refer this species to Pseudoclithria 

 as its clypeus is not at all notched in front, and its front 

 tibiae are usually tridentate in both sexes. By \Vestwood it 

 was referred to Diaphonia, and by Kraatz to Metallesthes. 



The upper-surface usually has a brassy-green gloss, but 

 occasionally the gloss is bluish. The elytra are usually as 

 dark or almost as dark as the prothorax, but occasionally 

 they are entirely of an almost brick-red colour, except for 

 a slight greenish gloss. One female in the South Australian 

 Museum has the elytra entirely red, and the base of the pro- 

 thorax partly diluted with red. On this female the submedian 

 teeth of the front tibice (fig. 175) are almost equal in size. 

 The front tibise are usually tridentate in both sexes, the sub- 

 basal tooth being much smaller than the others (fig. 173). 

 One male in the South Australian Museum, however, has the 

 front tibiae bidentate only (fig. 174). 



The male differs from the female in being smaller and 

 narrower, abdomen considerably smaller, slightly flattened 

 along the middle, with its outline as seen from the side feebly 

 concave instead of convex, and with the club considerably 

 larger. 



A male from Kooringabie. in Mr. Griffith's collection, 

 appears to represent an extreme variety. Its prothorax and 

 elytra are brick-red, with a slight bluish gloss, but the pro- 

 thorax has a fairly wide median dark vitta, interrupted just 

 before the base, and a small spot on each side slightly in 

 advance of the middle; the antennae (scape excepted), palpi,
