9 . Differs in having a shining and conspicuous inter- 

 ocular tubercle ; prothorax somewhat smaller ; elytra larger,, 

 wider, and more ovate ; basal segment of abdomen convex 

 and non-carinate ; legs somewhat shorter, front tibiae less, 

 curved, more sparsely clothed and the apex less acute ; the 

 clothing of the under-surface is also decidedly shorter. 



Hab. — Tasmania: Stanley, under stones and abundant 

 in grass-tussocks on summit of the "Nut" (A.M. Lea) : Vic- 

 toria: Forrest (H. W. Davey). 



Of the species belonging to the group with carinated 

 abdomen it is distinguished from all, of which the female is 

 known, by the conspicuous inter-ocular tubercle of the female. 

 Of those of which the female is unknown, it is distinguished 

 from imitator by the basal segment of abdomen of male less 

 incurved to middle, the carina much less curved, and front 

 tibiae less hairy and less curved. Lonrjicollis has prothorax 

 longer, elytra rougher and differently clothed, front coxae 

 more widely separated, and basal segment of abdomen less 

 incurved to middle. Excavatus and Severini have the 

 abdomen very different. It is very close to arciferus, and I 

 was at first inclined to regard it as a variety of that species, 

 but the clothing is not so dense, so that the prothoracic 

 granules are more distinct before abrasion, the elytra are not 

 subtuberculate posteriorly, have the alternate interstices 

 elevated, with the punctures, although still of large size, con- 

 siderably smaller (both before and after abrasion), the rostrum 

 somewhat stouter, and the scape is slightly thicker, except at 

 apex, where it is thinner. The under-surface and legs, usually 

 so distinctive of the species of this genus, are practically 

 identical. There is now no female of arcif erics before me, but 

 the inter-ocular tubercle of the present species is so distinct, 

 that had it been present on the type female of that species it 

 oould hardly have been overlooked. 



The clothing is very variable, and is seldom exactly alike 

 on any two specimens. It is usually of a dark ashen-grey, 

 mottled with small darker and paler spots (usually each shoulder 

 has a small pale spot). The suture, especially about summit 

 of posterior declivity, is more or less ochreous. On an occa- 

 sional specimen there are a few small shining granules on the 

 suture towards the base. 



Mandalotus irrasus, n. sp.

 or in parts diluted with red. Densely clothed with muddy- 

 brown scales, interspersed with suberect setae. 



Rostrum with a very narrow continuous median carina. 

 Scape somewhat inflated at apex, first joint of funicle about
