3. Olenecamptus nubilus spec. nov. 



c?. Similar to 0. hattanyi (1901) Villard, the greyish white pubescence 

 denser, the markings smaller, of the same colour as the pubescence, indistinct, 

 different in position ; prothorax longer and more strongly wrinkled, elytra mure 

 densely punctnred, etc. Tawny brown, antenna and legs paler than body, excepting 

 first two segments of former, rather densely pubescent ; the pubescence con- 

 centrated behind eye to a vestigial vitta, which is continued across thorax, but 

 is hardly discernible ; a triangular basal area of elytra, extending from shoulder 

 to shoulder, an antemedian, discal, irregular patch on each, three minute dots, 

 one in middle near suture, the second about 3 mm. from apex, also near suture, 

 the third between these two, but more lateral, greyish white ; pubescence denser 

 at sides of elytra than on disc. Sides of breast with an indistinct greyish white,

ON A NEW ROCK-WALLABY EEOM XOllTil-WEST 



AUSTRALIA. 



BY OLDFIELD THOMAS. 



TN 191)1 Mr. J. T. Tunney, before ])roceediag to North Australia to collect 

 J- the mammals of which an account is given in a sncceediug paper, obtained 

 a few kangaroos in the nortiiern part of AVestern Australia (about 22' S., 1 1.S° E.). 



The specimens are mostly referable to Mucrnimx rii/ua and .1/. robiistus 

 ceni/iiis, but in addition there is a skin, unfortunately without skull, of a new 

 Petrogale of the large P. peidcillata-lateralis group.
