of the front tibiae broken or worn down by digging). Her 

 punctures also are usually denser and larger than in the male. 



A very small male in the South Australian Museum has 

 an obscure pale spot on each side of the clypeus, and the 

 middle of the abdomen obscurely diluted with red. It is the 

 only specimen under examination whose head is not entirely 

 black. Its scutellum is entirely pale. It has an unusually 

 distinct fovea on each side of the pygidium, and its elytral 

 punctures are unusually large and conspicuously transverse. 



Another male (fig. 105) has the black basal edging of 

 the prothorax somewhat wider than usual, with a subtri- 

 angular extension from same to near the middle ; it also has 

 a fairly large isolated spot on each side of the basal third and 

 some blackish spots near the margins, somewhat in front of 

 the middle. Another male has somewhat similar but less pro- 

 nounced markings. 



Another male (fig. 106) has the black sutural marking 

 somewhat dilated towards the base, and the scutellum with 

 a subtriangular pale spot. 



A female (fig. 104) has the black basal edging of the 

 prothorax continued around the sides, and two blotches of 

 very unequal size on the disc. Its scutellum has two irregular 

 pale spots. On the elytra there is a large dark sutural 

 blotch, of an irregularly oval outline, from near the base to 

 the apical third, then continued narrowly to apex; there is 

 also a vitta from near each shoulder to the subapical callosity. 



A female (fig. 103), in Mr. Griffith's collection, has the 

 elytral markings conjoined, but otherwise somewhat similar; 

 its prothorax has two large and some small spots. 



A female (fig. 100) from Western Australia, in the 

 National Museum, Melbourne, has the elytra dark, except for 

 some basal markings. Its prothorax has two large and some 

 smaller spots. 



A female (fig. 101) from Eucla, in the National Museum, 

 Melbourne, has the elytra dark, except for some irregular basal 

 markings. Its prothorax has an irregularly M-shaped mark, 

 occupying most of its surface, and the small medio-lateral spots 

 are unusually well defined. This specimen was labelled 

 Lyraphora deyrollti, but is apparently not even close to that 

 species. 



Another female (fig. 102), also from Western Australia, 

 has the prothoracic markings still more extended, but on the 

 elytra the markings are somewhat as on the first described 

 female. 



Diaphonia gulosa, Janson. 



The mesosternal process of this species is certainly small, 

 but that appears to be its only aberrant feature, and it should
