The rostrum and antennæ are very peculiar; the clothing 
appears to be easily abraded, as it is only perfect in two out 
of seven specimens under examination. The species is allied 
to ferus (Pascoe), from which it may be readily distinguished 
by the absence of sutural tubercles at the summit of pos- 
terior declivity. 
LEPTOPS HORRIDUS, n. Sp. 
Male. Densely and uniformly clothed with scales varying on 
different specimens from slaty-grey to ochreous and dark 
brown; abdomen with an elongate, subelliptie, sooty-black 
patch. Moderately densely covered with short, stout sete, 
denser on rostrum than elsewhere; antenne and legs with 
pale elongate sete. 
Head with a feeble transverse impression between eyes. 
Rostrum moderately stout; with a narrow deep channel (more 
or less obscured by scales) іп middle; a short, deep, some- 
what curved sulcus on each side; scrobes short, deep, oblique, 
terminating considerably before eyes. Antenne moderately 
long ; scape short; joints of funicle subeylindrical, the second 
longer than first, all of them longer than wide. Prothorax 
feebly transverse (4 x 42), with several irregular transverse 
impressions; excavated along middle, the excavation inter- 
rupted in middle, anteriorly being horseshoe-shaped, pos- 
teriorly irregularly transverse, on each side in front an ele- 
vated ridge margining excavation. Wlytra considerably 
wider than prothorax, subparallel to near apex; subseriate- 
punctate, punctures large, more or less rounded, distant or 
approximate; suture аб summit of posterior declivity with 
two long subeylindrical tubercles scarcely conjoined at their 
bases; third interstice with four tubercles, of which the basal 
one is small, and the fourth (before the summit) larger, but 
not longer, than the sutural; five acute tubercles forming a 
row almost parallel with those on the third, but on different 
interstices, the basal one on shoulder, and directed slightly 
forward, the fifth on fifth interstice level with and very simi- 
lar to those on suture; a small tubercle on each side near 
apex, and a small one just behind shoulder. Length, T6. 
rostrum, 41 ; width, 73 mm. 
Female. Differs in having the elytra slightly more rounded 
and shorter, the tubercles larger at their bases, and less 
acute, and the humeral one not at all projecting forward. 
Length, 181; width, 8j mm. 
Hab.—Cairns (С. Masters), Barron Falls (A. Koebele). 
A narrow, elongate species, not close to any with which I 
am acquainted ; it perhaps belongs to the tribulus group.
