tate ; with a feeble median ridge continued to near antennae- 
Scape inserted two-fifths from apex of rostrum, almost the 
length of funicle ; second joint of the latter almost twice the 
length of the first. FrothoraT slightly transverse, subglobu- 
lar ; without punctures or tubercles. El ijtra ovate-cordate, 
widest at about one-third from base, less tlian thrice the 
length of prothorax, without tubercles : with series of mode- 
rately large (large at sides) punctures, which are partially 
concealed by clothing. Abdomen with third and fourth seg- 
ments not depressed, their combined length equal to that A 
second or fifth ; without large punctures except for a curved 
row on intercoxal process, and which, around the coxse, be- 
come compressed into a distinct groove. />'^,7-s unusually 
long and thin : posterior femora passing elytra : third tarsal 
joint wide. Length, 8^, : rostrum, 2^ : width, 4 mm. 
Rah. — Queensland: Cairns (George Masters). 
Belongs to the varirosiis group, but is, nevertheless, a 
distinct species, and is not close to any known to me- 
POROPTERUS CAVERNOSUS, U. Sp. 
Densely clothed with stout, suberect brownish scales al- 
most uniform in size and colour throughout, except that on 
the legs they are feebly variegated ; on the elytra they are 
most numerous on the alternate interstices, but even there are 
less dense than on the prothorax. 
Strongly convex. Punctures of liead and rostrum en- 
tirely concealed, but evidently very coarse ; eyes coarsely 
faceted. Rostrum noticeably incurved to middle. Scape 
inserted almost in exact middle of rostrum, much shorter than 
funicle ; second joint of the latter much longer than first, third 
joint almost as long as two following combined, none trans- 
verse. Frothora.r as long as wide, or slightly longer than 
wide, sides rounded : densely and coarsely punctate, punc- 
tures entirely concealed. Elyrrd elliptic-ovate ; decidedly 
raised above, scarcely twice the length of and once and one- 
half the width of prothorax ; with nine series of large, regu- 
lar foveiform punctures ; the interstices narrow, not much wiaer 
than the transverse ridges between puncture and puncture- 
A.hdonieii without distinct punctures, third and fourth seg- 
ment>s combined slightly shorter than second. l-^fl^ mode- 
rately long ; posterior femora extending to apex of elytra ; 
third tarsal joint moderately wide. Length, 6-| : rostrum, 
I5 ; width, 3 mm. 
Hah. — Queensland: Cairns (Macleay Museum). 
Belongs to the raricosus group, and with an outline some- 
what similar to that of the preceding species : from which, 
however, it totally differs in the punctures and legs : of the 
described species it is perhaps closer to rra^isicorni.^ than to
