The eight first species named in the above list pertain to the 
family of Tiger Beetles (Cicindelidje), and are quite similar in 
their size, colors and marks to our American species, considerably 
numerous, belonging to the same genus. 
The thirty-eight succeeding species (No. 9 to 43) and the eight 
near the close of the list (No. 120—127), belong to the family 
Carabidje, one of the most extensive groups in this department 
of nature’s works. Of these, we look with the most interest upon 
the two species of Graphipterus, this being a genus of insects pecu¬ 
liar to the African continent; and the white spots and stripes 
with which they are ornamented, are marks so unusual among 
the larger Carabidce , that at first glance one would not suspect 
them to pertain to this family. With the still larger species of 
the allied genus Anthia (for specimens of which, my cabinet is 
indebted to Rev. David Irvine, late a missionary of the Presbyte¬ 
rian Board, in India), these insects show, in the marks alluded to, 
a relationship to the preceding family, and the gradual transition 
by which nature passes from one group to another of her works. 
Several of these Carabidce are very like our American insects of 
the same genera; but it is rather remarkable that of the genus 
Ditomus, of whieh about two dozen species occur in the several 
countries bordering upon the Mediterranean and Black seas, we 
have no representative in corresponding latitudes upon this side 
of the Atlantic. 
All the insects of these two families are carnivorous, attacking 
and devouring other insects. But though this is their general 
habit, it is now well settled that some of the species are injurious 
to fields of wheat, feeding upon the young plants and upon the 
grain in the ear. No. 3G of the above list, Broscus cephalotes, is 
one of these species. Though these two families have probably 
been more studied than any other insects, it is to be regretted that 
so little attention has been bestowed upon the habits of the seve¬ 
ral species in their larva and perfect states. 
The twenty-eight next species (No. 44 — 69) pertain to the old 
Linnsean genus Scarubeeus, which forms several families in system¬ 
atic works at the present day. Of these insects, a portion feed
