part, is of a darker brown than the base; the under-parts 

 are as on the type. 



MORDELLA SUBVITTATA, Mad. 



In general appearance the type (and only specimen I 

 have seen) of this species is much like wiburdi on an enlarged 

 scale; but besides size, it differs from that species in being 

 narrower, with the pygidium more gradually tapering 

 to its tip. 



MORDELLA SYDNEYANA, Blackb. 



Typical specimens of this species are readily distinguished 

 from typical ones of cara by the shape of the subapical spot 

 on each elytron ; but specimens whose markings tend to 

 obliteration are not always easily distinguished from that 

 species, or from spotted specimens of promiscua ; whilst some 

 are scarcely distinguishable from specimens of anstralis whose 

 oblique subscutellar vitta is vaguely defined. 



Var. cairnsensis, n. var. 

 Numerous specimens from Cairns (F. P. Dodd) differ 

 from the typical form in being smaller (3 \ mm.), and with 

 the pale clothing of the metasternum confined to the sides 

 and intercoxal portion. 



MORDELLA TRISTIS, Lea. 



On the male of this species the front tarsi are conspicu- 

 ously dilated, being wider than the tibiae, the two basal 

 joints are distinctly longer than wide, the third is slightly 

 longer than wide, and the fourth is as long as wide (on some 

 specimens it appears to be feebly transverse) ; the only species 

 w T ith larger tarsi that I have critically examined is tarsalis. 

 The head (especially in the male) is of a more or less brilliant 

 bluish-green, altering with every point of view. The species 

 is common in Tasmania, and occurs at Jenolan, as well as 

 on Mount Kosciusko, in New South Wales. 



MORDELLA V-AUREA, Lea. 



A specimen from the Capel River (Western Australia) 

 agrees perfectly with the type, except that the subapical 

 markings of the elytra are conjoined to form a bisinuate 

 fascia . 



MORDELLA VERTICORDAE, Lea 



On typical specimens of this species the elytral pubes- 

 cence, although paler on the suture than on the sides, is not 

 sharply defined there, the colour gradually changing ; on 

 the abdominal segments also there are no conspicuous dark
