510 Mr. T. Yernon WoUaston on the 
Dryophtliorides distinctly 5-jointed (the fourth one in that 
subfamily not beino; minute and hidden, but appreciable 
and unreceived). Yet so completely was Lacordaire led 
into error by the original diagnosis, that he not only 
accepted the insect (on account of the supposed structure 
of its funicidus) as a DrijoplitJiorid, but naturally enough 
felt compelled so far to modify the characters of that well- 
defined subfamily so as to admit within its bounds the 
ordinary pseudotetramerous foot ! It is, however, in re- 
ality, a normal member of the Pentarthrides, and is very 
intimately related to my genus Pentacoptus Avhich was 
detected by INIr. G. Lewis in Japan. It completely lacks, 
moreover, the fusiform, or subelliptic, outline of the Dry- 
oplitJiorides ; whilst its exceedingly incrassated legs and 
tarsi are in strange contrast with those of that subfamily — 
in which those parts are comparatively thin and wiry ; 
and its eyes (instead of being sunken, transverse, and de- 
pressed) are rounded and very prominent — as in the Pen- 
tarthrideous Pentacoptus. Its metasternum too is shorter 
than that of the Dnjoplitliorides ; and its four anterior 
coxa3 are perce])tibly more approximated. 
From the Japanese Pentacoptus (to which it is inti- 
mately allied), Chcerorrhinus differs mainly in its larger 
size and less narrowed prothorax, in the cariniform struc- 
ture on either side of its elytral apex, in its anterior coxa3 
being rather less widely separated, and in its first and 
second abdominal segments being divided by a very deeply 
sinuated line, instead of a perfectly straight one. 
The ChcBrorrliini appear to occur in southern Europe, 
the genus having been first met with in Sicily. 
8. Pentacoptus (^Yollaston, Trans. Ent. Soc. Lond. 
12. 1873). — In its very coarsely sculptured and opake, 
though somewhat besmeared surface, its short, broad, 
parallel rostrum, nearly obsolete scutellum, and costate 
elytra, the j^resent remarkable little genus has almost as 
much in common, at first sight, as Chcerorrhinus has, 
with the Dryophthorides I nevertheless its 5-jointed funi- 
culus, and its small, rounded, and prominent eyes, in con- 
junction Avitli its elytra showing no traces of the peculiar 
cariniform structure at their apex which is so marked a 
feature in that group, its comparatively incrassated legs, 
and its ordinary pseudotetramerous feet (the third joint of 
which is a good deal widened and bilobed), will of them- 
selves at once remove it from the members of that sub-
