D. Suarp—Topogruphical Tuble of Hawaiian Coleoptera. 267 
The family Buprestide is represented by a single North American species, 
found at Honolulu. 
The Elateridz have seven genera and fourteen species. Five of these genera 
are known outside the islands, and have each only a single species, four of the 
species being also known as foreign. The two genera at present peculiar have 
nine species between them, and at present I can form no opinion whether they will 
prove autochthonous or not; possibly they may do so. 
The Malacodermidz have two genera and two species, one genus and both the 
species being peculiar. Both these insects are found only in Honolulu, and (as the 
peculiar genus is an extremely obscure and minute creature) are probably of foreign 
origin. 
The Cleridz consist only of three widely distributed species. 
The Ptinidz, on the other hand, comprise six-genera and twenty-three species. 
Three of the genera, having between them four species, are of foreign origin, and 
three of their four species are known elsewhere. The other three genera have 
nineteen species between them, and there is no evidence to show that they are of 
foreign origin other than that they are pre-eminently wood feeders; the genus 
Mirosternus belongs to a different group to what the other two genera do; and it is 
my opinion that while these latter may probably prove autochthonous, Mirosternus 
may more probably be found elsewhere, it being a highly specialised—while Hol- 
cobuis and Xyletobius are generalised—forms. 
The Bostrichidee have five genera and five species. The members of this 
xylophagous family are widely distributed, even in remote parts of the earth, and 
all the Hawaiian species are foreign. 
The Cioidze are a small family of obscure beetles, living in boleti. From all 
parts of the world scarcely 200 species are known; it is, therefore, remarkable 
that there should be twenty already discovered in the islands whose fauna we are 
considering. Although these twenty species are referred all to one genus—Cis— 
they form really a most varied assemblage, exhibiting, I believe, a greater variety 
of forms than could be found in all the other members of the genus—and their 
number is more than one hundred—at present known from all parts of the earth. 
Some of the Hawaiian species, indeed, scarcely possess the facies of the family, so 
that they were not at first recognised either by Mr. Blackburn or myself as belong- 
ing to it; and as the family is, though much neglected, really an interesting one on 
account of its unspecialised (or, as some would say, ‘‘ ancient”) character, these 
Hawaiian Cioide are really of great interest and importance. 
The enormous family Tenebrionide has seven genera and eight species. The 
genera are all known from elsewhere, as are also six of the species, and the other 
two species, belonging to obscure and neglected genera, will pretty certainly also 
prove to be foreign. 
The Cistelidze have two genera and two species. ‘This family is suffering from
