position of Georrhynchus must be, of necessity, amongst 
the Cossonids. 
32. Onycholips (Wollaston, Trans. Ent. Soc. Land. v. 
389. 1861). — It was not without some degi'ee of hesitation 
in the first instance, that I decided on recognising the 
anomalous- genus Onycholips as the type of a subfamily 
of the CossonidcB ; more especially since Lacordaire has 
expressed a doubt as to its true location, and hints that 
it may perhaps be necessary to establish a distinct family 
of the RJiynchophora to receive it, — along perhaps with 
Georrhynchus (the almost equally unintelligible Curcu- 
lionid just alluded to, with apparently somewhat similar 
subfossorial habits, detected at Montevideo). Yet, de- 
spite its many eccentricities, some of which would seem to 
debar it from nearly every department of the weevils which 
has hitherto been defined (and which must remain, con- 
sequently, anomalies icherever the genus be placed), the 
more I study its various details (structural and external), 
and its fossorial mode of life, the more convinced am I, as 
at first, of its not very distant relationship with such blind 
members of the CossonidcB as Pentatem7ius , Halorhynchus , 
and Lipommata (particularly the former), and even more 
so perhaps with the equally blind Raymondionymus and 
Alaocyba, — all of which have either burrowing or sand- 
infesting habits, and slightly pilose bodies, and which show 
some kind of tendency for unusual tibial developments ; the 
last tivo, moreover, having a 6-jointed funiculus, and 
quadriarticulate feet. Perhaps the most significant points 
however, which have been urged as tending to remove it 
from the CossonidcB are embodied in the twofold fact that 
its first and second abdominal segments are not completely 
soldered, and that its intermediate coxaj are almost (like 
the anterior ones) contiguous ; but, on the other hand, 
there are many undoubted Cossonids in which the first 
and second segments of the abdomen are not absolutely 
confluent, being (as in Hexarthrum, Brachytemnus and 
SphcBrocorynes) separated from each other by a most con- 
spicuous sutural line ; wdiilst certain, also, of the sub- 
Hylastideous genera of the true Cossonides have (like 
Hexarthrum, Stereocorynes, Tomolips, Brachytemnus, 
Stenoscelis, and others) their intei-mediate legs (no less 
than their anterior ones, almost completely in contact, and 
I think tlierefore that neither of those characters will
