Australian and Tasmanian Mordellidie. 7 



Hob. W. A. : Pinjarrah. 



A narrow species, in general appearance suggestive of a 

 Morddlistcna, but the posterior tibiae and tarsi are of normal 

 form. Numerous specimens were taken by means of the 

 sweeping-net. 



MORDELLA VERTICORDIiE, n. sp. 



Black ; densely clothed with grey, silvery-grey, golden-grey, or 

 greyish-brown pubescence of an uniform shade on the upper surface, 

 except that on the scutellum and suture it is almost white. Under 

 surface and legs with greyish-white pubescence. 



Aculeus rather short, sides strongly and not regularly decreasing 

 in width to apex, which is finely but very distinctly emarginate. 

 Posterior spurs decidedly unequal, the longest half the length of first 

 tarsal joint. 



Length b\-1 m.m. 



Hah. W. A. : Mount Barker {B. Helms), Mogumber {Lea). 



A very distinct species, on account of the emargination 

 of the apex of the aculeus. In general appearance it is 

 close to the preceding, except that the pubescence is 

 denser. Numerous specimens were seen on the blossoms 

 of various species of Verticordia. 



MORDELLA INORNATA, n. sp. 



Black ; base of antennae and posterior spurs reddish-piceous. 

 Pubescence black ; on the head and front part of prothorax appear- 

 ing greyish-brown in certain lights ; on sides of sterna and abdo- 

 minal segments with a silvery gloss in certain lights. 



Aculeus long, thin and regular, apex very acute. Posterior spurs 

 equal and less than half the length of first tarsal joint. 



Length 9-ll| m.m. 



Hah. N. S. W. : Victoria {G. French). 



The largest black species hitherto recorded from 

 Australia, and with a remarkably sharp aculeus. The 

 pubescence from most directions appears to be entirely 

 black. 



MORDELLA APICATA, n. sp. 



Black ; upper surface densely clothed with greyish or reddish- 

 brown pubescence, except on apical fifth of elytra, where it is black ; 

 sides of sterna, sides and middle of each of the abdominal segments, 

 and base of aculeus, with greyish- white pubescence.
