CLASSIFICATION OF THE RHYNCHOPHOROUS COLEOPTERA. 391 
and the Rhynchitidæ to the Belidæ, the last ES in the third 
series of Rhynchophora. 
The habits of the species of this series are peculiar, and quite 
different from those of the next series, and indicate as is wisely 
observed by Lacordaire,* for the care of their progeny, an industry 
which appears here for the first time in the family. I cannot de- 
scribe the results of this instinctive or intelligent industry better 
than by condensing the account of the author just cited, referable 
however to European species. 
1. Rhinomaceridæ. The European species deposits the eggs 
in the male flowers of Pinus maritimus, the development of which 
is thus prevented. I may be allowed to observe that this synthetic 
genus, the nearest approach in the Rhynchophora to the lower 
Heteromera, and therefore the representative of old mona clings 
to an old and synthetic type of vegetation. 
2. Rhynchitidæ. Some of the species of Rhynchites roll leaves 
inthe manner of the next family. Others deposit their eggs in 
young fruit, the kernel of which is eaten by the larva; others again 
place the eggs in the undeveloped buds of trees, which are thus 
destroyed. 
3. Attelabide. In the spring the females roll up the leaves of 
trees, and deposit in each an egg. After emerging from the egg 
the young larvæ eat the inside layer of the case which covers them, 
which they probably leave at a later period, when their growth is 
complete, to perfect their metamorphosis under ground. 
These three families are of small extent, and oe little need be 
Said regarding their classification. 
RHINOMACERID#. 
This family is represented in our fauna by two species, one on 
each slope of the continent, and is easily recognized by the de- 
pressed, curved and acute mandibles, and distinct labrum. The 
Pygidium is covered by the elytra, which are punctured without 
any appearance of striæ. On the inner face there is no trace of 
a lateral fold: the epipleure are indistinct. 
ATTELABID&. 
Four species of Attelabus on the Atlantic slope are the only 
representatives thus far known in our fauna. The beak is stouter
