very strong narrow central keel runs from a little behind the 
frontal tubercles nearly to the apex of the rostrum, but is in- 
terrupted between the tubercles ; an obscure thick keel on either 
side connects the tubercles and the apical ci’ests ; the scrobes are 
flexuous and posteriorly obscure. The prothorax is about a quarter 
wider than long, flattened or slightly concave do^vn the disc with 
two tubercles (about equal in size to those on the head) narrowly 
separated at the anterior margin; the whole surface is covered with 
small shining tubercles of unequal size ; the sides are gently arched. 
The elytra at their base are scarcely wider than the prothorax and 
are widest about the middle : each elytron bears a sutural row of 
small tubercles, with a very large tubercle curved backwards at the 
summit of the declivity, followed by a row of five large tubercles 
at equal distances apart from base to near apex (the fourth the 
largest) ; then a row of four tubercles commencing behind the 
base, and finally two tubercles, one a little behind the shoulder, 
the other a little before the middle ; the whole surface is coarsely 
rugulose and furnished with small obscure tubercles. The 
funiculus of the antennre is veiy stout, the club nearly as long 
as the preceding four joints together, and (at its widest part) 
considerably wider than the funiculus (the joints of which are all 
subequal). 
From all the previously described species of Laptops having 
interocular tubercles, this species appears to be well distinguished 
by the two large tubercles on the front of the prothorax. It is 
probably nearest to L. vmsimon, Pasc., which (besides the 
dift'erence just mentioned) has the club of the antennae not 
thicker than the funiculus, &c., ii:c. 
Taken on Fraser Island and sent to me by F. M. Bailey, Esq., 
F.L.S., Colonial Botanist of Queensland, with who.se name (so 
widely known among botanists) 1 have ventured to associate this 
insect.
