6 Mr. A. M. Lea's List of the 



Aculeus rather short and stout, but apical two-fifths much nar- 

 rower, apex truncate. Posterior spurs unequal, the longest more 

 than half tlie length of tlie first tarsal joint. 



Length 42-6 m.m. 



Hah. W. A. : Mount Barker (Andrew Muir), Garden and 

 Rottnest Islands {Lea). 



Very close in general appearance to M. caret. 



MORDELLA BREVIS, n. sp. (Plate II, fig. 33.) 



Black ; anterior legs, posterior spur.s, muzzle, palpi a;id Ijasal 

 joints of antennic reddisli-testaceous. Head with greyish pubescence ; 

 prothorax with silvery pubescence, with a large median and two large 

 lateral vitt;e (these sometimes occuj^y almost the entire surface so 

 that the wliite markings are entirely marginal) ; each elytron with 

 white markings as follows : along base, where between side and 

 suture a stripe (sometimes entirely disconnected) projects down- 

 wards ; along suture to before middle, where it curves outwards and 

 downwards, then upwards and then almost straight outwards to 

 margin ; near apex a large semilunar patcli. Under surface with 

 silvery and black pubescence. 



Aculeus rather short and stout, but apical half much narrower 

 than basal, apex obtuse. Posterior spurs unequal, the longest more 

 than half the length of first tarsal joint. 



Length 2^-3 m.m. 



Hah. W. A. : Mount Barker {R. Helms), Bridgetown, 

 Garden Island {Lea). 



This species is rather close in general appearance to the 

 one I have supposed to be M. australis, but it may be at 

 once distinguished from that species by the shape of the 

 median fascia and the absence of an oBli([ue scutellar stripe. 

 The markings are much more sharply defined in some 

 specimens than in others, the basal stripe being especially 

 liable to partial obliteration. 



MORDELLA CUNEATA, n. Sp. 



Black ; legs (except the posterior femora and apex of tibiic and 

 tarsi, which are black) red ; basal joints of antennae obscure red. 

 Uniformly clothed with greyish pubescence — no darker on the under 

 than on the upper surface. 



Aculeus not very long and stout, sides regularly diminishing in 

 width to apex, which is obtusely rounded. Posterior spurs une(|ual, 

 the longest less than half the length of the first tarsal joint. 



Length 4i-6i m.m.
