SYSTEMATIC ARRANGEMENT. 
number of simple eyes, the only kind with which 
these larvae are provided, varies from one to six ; the 
former is exemplified by Telephorus, the latter by 
Carabus. In the larvae of Cicindelae the two posterior 
ones have a red pupil surrounded by a pale iris. 
The larvae of many different kinds — commonly termed 
grubs by husbandmen — are productive of great injury 
to cultivated plants, both when growing, and after 
they have been harvested. 
Of all the orders perhaps this is the one that has 
been most studied, a preference which it owes to the 
great beauty of many of its foreign species, the end- 
less diversity and singularity of their forms, the dis- 
tinctness of their external parts, and the ease with 
which they can be preserved in unimpaired beauty 
for an indefinite length of time, as well as other con- 
siderations, calculated to recommend them to notice. 
It is partly from the zeal with which they have been 
sought after, that their number has always appeared 
so much greater than that of the other orders, which, 
now that they have attracted more attention, are 
found to make a nearer approach to them in this re- 
spect than was formerly imagined; still, however, 
the preserved examples are considerably most nume- 
rous, as is likewise, there can be no doubt, their ab- 
solute amount in nature. The collection of the Count 
De Jean has been augmented, in the short period 
that has elapsed since we last mentioned the amount 
of its contents, to nearly 23,000 species, and it is 
conjectured that about 6000 or 7000 others exist m 
the Parisian cabinets. The collection of beetles in
