A numlxT of si)ocimons from (^iccTisland ami Victoria, and two from Tasmania 

 (Brigliton). Also three ])resente(l by Mr. H. Schra.ler. two being from Tingha and one from 

 the rlareiice River, both in New South Wales. Length 30-5-37-0 mm. 



The iii)per surface of the head resembles that of M. dihtkUus, e.xtept that there is a 

 secondary t\ibercle deveh)ped on the upper side of the base of each of the outer tubercles, 

 which conseiiuently appear very high and obliquely tnmcate in side view. The ridge

buundiug posteriorly the crescentic groove on the mentum is u.sually more pronounced, 

 and the lateral matt border is very broad and extends round in front on to the inner 

 side of the punctured area. The punctures in the lateral grooves of the elytra, though 

 simietimes irregular, and inclined to be more or less transverse behind, as a rule resemble 

 those of M. quaestionis and mtstralasicus more closely than they do those of .1/. diJntatus.

Two specimens from New South Wales. Length 33 mm. 



The small triangular frontal area is bounded laterally by high frontal ridges and inner 

 tubercles, somewhat as is M. qmestionis, but is not itself elevated. The ridges joining the 

 inner tubercles to each other and to the outer tubercles are abscmt, a broad transverse 

 Hattened rugose band extending between the supraorbital ridges from the inner tubercles 

 to the anterior margin of the head ; behind this band the head is smooth and glossy. The 

 mentum is somewhat coarsely and sparsely pimctured between the scars, with a more or 

 leas triangular, extensive (but sometimes indistinct) depression in front. Its lateral parts 

 are more closely and finely punctured on the inner side, obhquely striate with a m<.re or 

 le.ss .smooth nxatt border on the outer. 



The median groove of the pronotum is deeply impressed, but may be iiuomplete m 

 front ; the marginal grooves are coarsely punctured in their anterior exvrenuties. which 

 bend slightly inwards ; the remainder of them is very finely pmictiired. as are also the 

 pronotal .scars. The general surface of the pronotum is unpunctured. The scutelhim
