Genera of the CossonidcE. 509 
Amongst other peculiarities, our present insect is remark- 
able for its elliptic outline, for its long and parallel but 
arcuated rostrum, for its funiculus being gradually much 
increased in width towards the club, and for the latter 
being extremely large and solid, — though obliquely trun- 
cate at the inner apex, at which particular point it is 
densely clothed with a velvety pubescence. Its prothorax 
(which is but shghtly constricted in front) is nearly cylin- 
drical, and very much narrower than the elytra, the latter 
(which have their interstices, especially the alternate ones, 
costiforra) are wide in front but acuminated behind, its 
legs are exceedingly long and thickened, its tibias are 
somewhat curved (the four hinder ones moreover being 
armed at their apical angle with a short but robust spine), 
its third tarsal joint is simple, and its front coxa? are con- 
tiguous, the intermediate ones but very slightly separated, 
and the hinder pair exceedingly remote. 
The S. conjluens is from the collection of Mr. Pascoe, 
and was taken by Mr. Wallace at Sarawak in Borneo. 
7. Cii^RORRHiNUS (Fairmaire, Ann. de la Soc. Ent. 
de France, 742. 1857). — I am indebted to John Gray, 
Esq., for an opportunity of inspecting the European genus 
Clicerorrhinus , of Fairmaire ; and it is not without the 
greatest astonishment that I have observed the excessive 
inaccuracy of the original diagnosis in assigning it to the 
D njophthorides, — an inaccuracy which is quite unpardon- 
able, and which has misled every subsequent author (in- 
cluding even Lacordaire) who has been content to trust to 
the published details, and not to examine them for him- 
self. The prima facie aspect of its opake, deeply-sculp- 
tured surface, which is besmeared with dirty, mud-like 
scales, in conjunction with the cariniform structure on 
either side of its elytral apex, are without doubt marvel- 
lously suggestive of DryophtJiorus, — so much so indeed 
that it may fairly be regarded as establishing, in conjunc- 
tion Avith Synommatus, a curious affinity between the 
Dryophthorus-tyY)e and the subfamily Pentarthjndes (to 
which it belongs) ; but there the resemblance altogether 
ceases ; and it is surprising how any careful Coleopterist 
could be misled by characters so eminently superficial. 
In real fact its funiculus is ^«e-ai'ticulate, which at once 
removes it from the Dryopltthoridcs — in which that organ 
is composed of only four joints. Then its feet are on the 
ordinary pseudotetramerous pattern, instead of as in the
