The pubescence of the elytra and undersurface of this species is 

 similar in character to the preceding, but it is never so brilliantly 

 silvery. 



MORDELLA ^MULA, n.sp. 



Differs from J/, fugitiva in being smaller, narrower, the elytral 

 pubescence less strongly marked, two small spots near apex of 

 elytra, base of antennae obscurely piceous; posterior femora 

 piceous-black, but distinctly lighter in colour than al^domen; and 

 by the aculeus. Length 7, width 2 J mm. 



Hab. — Mt. Kosciusko (Mr. W. Rajmiond). 



As the four preceding species strongly resemble each other it 

 may be as well to point out their chief differential characters. 

 31. trivialis has the head and prothorax densely and equally 

 covered with griseous pubescence, the aculeus long, narrow and 

 nowhere suddenly lessened. The other three species have the 

 head only covered with griseous pubescence, and that not so 

 bright as in triviali<i. J/. Raymondi has the aculeus shorter than 

 in trivialis, strongly lessened about its middle, then very gradually 

 decreasing in width to apex, which is truncate. J/, fugitiva has 

 the aculeus short, suddenly lessened at about its middle, rather 

 broad and parallel-sided from there to apex, the apex truncate. 

 J/, aumda has the aculeus fully as long, but not so narrow as that 

 of trivialis, its sides very feebly diminishing iii width from base 

 to apex, apex sharply truncate. 



MoRDELLA MaSTERSI, n.sp. 



Black; posterior spurs testaceous. Covered all over with 

 greyish pubescence, paler and shorter on the undersurface; on the 

 elytra there are very indistinct traces of markings towards the 

 apex. 



Aculeus long, from the base to about the middle decreasing in 

 width as the elytra, from the middle narrow, apex sharply pointed. 

 Posterior spurs subequal, about two-fifths the length of the first 

 tarsal joint. Length 3J-4;|, width 1-1 ;\ mm.
