morychus to receive a species having a peculiar process over 
each eye, processes reproduced in the present species, I have 
thought it best to refer it to the latter genus. The two 
genera are closely allied, and in common have many of the 
characters of Rhadinosomus. The above species must be 
very distinct from O. angustus, for, besides being consider- 
ably larger, its elytra are not conjointly rounded, the ros- 
trum is wider in the middle than at its base or apex, and 
its clothing (slightly similar on the flanks of the prothorax) 
is most remarkable: the prothorax is longer than wide, and 
not bisulcate. Of O. angustus Mr. Blackburn says it has the 
rostrum “dilating greatly forward from its base in such 
fashion as to bear a certain resemblance to a funnel, the wide 
end of which is the apex of the rostrum." This is also true 
of the above species, but only in regard to its under surface. 
Besides the specimens described I have two others under ex- 
amination, in neither of which are the scales so distinctly 
coloured, being almost uniformly dingy grey, the scales on 
each side of the median line of the prothorax and on the ros- 
trum being of a pale brown. In all three, however, the 
character of the scales on the rostrum is the same. 
OPHTHALMORYCHUS (METHYPORA) PARALLELUS, Lea. 
Atthetimethat this species was described I had not criti- 
cally examined many weevils, and in consequence was easily 
led astray by its superficial resemblance to Methypora pos- 
fica. Тһе species, in fact, is very distinct from Methypora, 
having the remarkable lateral extension over each eye char- 
acteristic of Ophthalmorychus; although possibly a new 
genus will ultimately be required to receive it.* ^ From the 
preceding species it differs (besides in many minor details) in 
having a much more parallel outline, the prothorax consider- 
ably longer than wide, and fully as long as head and pro- 
thorax combined, antennæ scarcely extending to anterior 
coxæ, and the legs very decidedly shorter and stouter. 
HOMGTRACHELUS HADROMERUS, n. Sp. 
Black; legs and antenne red, club and claws brown. 
Densely clothed with rather stout, feebly glistening scales. 
Head and rostrum feebly convex, the former with a very 
narrow impression between eyes. Rostrum very indistinctly 
depressed along middle. Scape about the length of two 
basal joints of funicle ; of these the first is stouter and slightly 
longer than second. Prothorax transverse, base almost trun- 
cate, sides moderately rounded; densely and coarsely punc- 
* There are at least three other species in the Macleay Mu- 
seum having these peculiar processes, all of which appear to be 
undescribed.
