From Rhyncolus, on tlie other hand, (with which they 
agree better in their more separated cox^, more elongate 
bodies, and developed scutellum), the members of Phloeo- 
phagosoma differ in their very much slenderer and more 
lengthened rostrum, in their less thickened and more 
medially implanted antennas, which have a larger and 
more abrupt club, and in theu' less prominent eyes. And 
they are also larger than the Rhijncoli, and have their 
anterior coxa3 (particularly however the intermediate pair) 
rather more remote from each other, — though these two 
characters are less strongly expressed than they were as 
compared with the corresponding ones of Phloeophagua* 
Tlie species now before me, which I should regard as 
]iertaining to Phlceophagosoma, are firom Japan, New 
Zealand, the islands of the Malay archipelago, Malacca, 
Ceylon, Malabar, and southern Afi-ica. The one fi-om 
the last-mentioned of those regions (which has been com- 
municated by Mr. Janson) has the name " Phlceophagiis 
eheninus, Schon." appended to it, but it scarcely seems 
to me to tally with the published diagnosis of that insect. 
51. PnOLiDOFORUS (AYollaston, Trans. Ent. Soc. Loud. 
18. 1873). — The present genus was proposed in order to 
receive a very singidar Curculionid which appears to be 
common in the Japanese archipelago, — Avhere it Avas de- 
tected near Nagasaki, in the island of Kushiu, by Mr. G. 
Lewis. It is at once remarkable amongst the 'Cossonida 
for the thick, cinereous, bristle-like scales Avith Avhich it is 
densely studded, — a type of clothing with Avhich we are 
very familiar in other departments of the RJigncliophora, 
but which is of the rarest occun-ence in the Cossonids. 
In other respects it is conspicuous by its narroAvish-fiisi- 
form outline (A\'hich is parallel in the middle, but much 
attenuated both before and behind), for its rather elongated 
antennae and feet, for its eyes being exceedingly prominent, 
and for its third tarsal joint being a good deal expanded 
and bilobed.

• In the species of Phlceophagosoma, which I rcfiarcl as the more typical 
ones, the rostrum is of equal breadth throughout ; but in others it is'eithev 
(as in the P. cvrvirostrin from Japan) a little thickened at the base, or else 
(as in the P. fusirostris from New Guinea) slightly and gradually so 
behind the middle.
