10 ON THE COLEOPTERA OF AUSTRALIA 



Antennae densely pubescent, in the male about one and a-half 

 times as long as the body ; 1st joint enlarged, similar in form to 

 that of the preceding species, but not so much produced outwardly 

 at the apex. Protliorax transverse, a few scattered punctures on 

 eifeher side of the middle, with two anterior and two posterior 

 transverse impressed lines, the two former interrupted in the 

 middle, and all, except that nearest the posterior margin, some- 

 what obscui'e. Scutellum rounded behind, impunctate. Elytra 

 considerably narrowed behind, rounded at the apex, the punctu- 

 ation gradually decreasing in strength posteriorly. Underside 

 and legs strongly pubescent. Length, (J 21 mm. ; ^ 24 mm. 



Cape York (Powell), Duaringa (G. Barnard), Queensland. 



This species belongs to the group of the genus in which the 

 antennae do not exceed the length of the body by more than about 

 one half its length. It is most nearly allied to M. argentatus, 

 Hope, but it has not the same silky appearance, and the antennae 

 are more densely pubescent. The head is also much less punctured 

 behind the eyes, and the lateral spines on the prothorax are less 

 prominent. 



Rhytiphora Rosei, sp.n. 



Elongate, nearly parallel-sided, piceous, very densely clothed 

 with silvery-grey, almost white, pile ; prothorax with transverse 

 bands of pile ; elytra irrorated with black and white. 



Head piceous, irregularly and not very closely punctured, 

 rugulose between the eyes ; the face, a narrow cii'cle round the 

 eyes, and an oblique stripe on each side, silvery-white ; median 

 line distinct. Antennae a little longer than the body, each joint 

 (except the basal, which is wholly piceous) thickly clothed with 

 silvery-grey pubescence at the base, and with black pubescence 

 at the apex, the grey pile decreasing in extent, joint by joint, 

 towards the apex. Prothorax piceous, rather strongly trans- 

 versely strigose, with a few punctures on the disc, banded trans- 

 versely with silvery-grey, the sides wholly grey. Scutellum 

 elongate, rounded behind, inconspicuously punctured. Elytra 

 very convex, the apex rounded, with a few large irregular
