complete neglect, so that although both of the Hawaiian species and one of the 
two genera are as yet peculiar, there is no reason for believing they will not be 
found elsewhere. 
The Anthicidz and Gidemeride are also families whose exotic members are very 
incompletely known, so that it is probable that their three members in the Hawaiian 
archipelago may be found elsewhere ; one of them, indeed, is known to occur in 
the Marquesas, and another is found only near Honolulu, where it especially fre- 
quents the flowers of exotic eucalypti. 
The family Aglycyderide may be looked on as peculiar to the Sandwich 
Islands. It is true that two members are known from other parts—one from the 
Canary Islands, the other from New Zealand—but these two are so different in 
certain important respects from the Hawaiian forms that the late Dr. Leconte con- 
sidered them entitled to family distinction. Whether that be the case or not it is 
at least certain that the Aglycyderide form one of the most interesting of all the 
families of Coleoptera, and it appears to have claims to be considered absolutely 
the most primitive of all-the known forms of Coleoptera, it being a synthetic form 
linking the isolated Rhyncophorous series of families with the Clavicorn series. 
About thirty species are known in the Hawaiian Islands, and they exhibit much 
difference iter se, but cannot at present be treated as forming more than one 
genus; many of the species are most difficult of study, owing to the great sexual 
disparities, and the apparently very close alliance between the various species in 
the most obscure part of the genus. Hence it is'probable that accurate observation 
may show that the number of true species may prove considerably greater or con- 
siderably less than that I have mentioned. 
The Curculionidz are the most extensive of all the great families of Coleoptera, 
and there are at present known fifteen genera and forty-nine species in the 
Hawaiian Islands. This number, requires, however, analysis before we can com- 
prehend its significance. The sub-family Otiorhynchini has one genus and two 
species peculiar ; the Cyladini have one widely-distributed species ; the Cryptorhyn- 
chini are represented by Acalles, with five peculiar species, and two allied genera 
(whose members are so rare that I have not been able to get a sight of them from 
Mr. Blackburn), each with a single species; then we have the Calandrini, with two 
genera and four species, three of which are already known from elsewhere, while 
the other is a small insect with habits rendering it probable that it also is of 
foreign origin; then comes the sub-family Cossonini, having eight genera and 
thirty-four species—that is, more than two-thirds of the whole of the Curcu- 
lionidz of the islands. That the Cyladini and Calandrini are all foreign is certain ; 
and I believe this will prove to be the case also with the Otiorhynchini* and the 
* Since this was written a species’ of the Otiorhynchus genus, Rhyncogonus, has been detected in 
the Marquesas Islands by Mr. J. J. Walker.
