COLEOPTERA. 



BRUCHUS, LinncBUS. 



In Bruchus proper, the antennae are filiform and frequently serrated or 

 pectinated; the eyes are emarginated. The posterior legs are usually very 

 large. 



The females deposit an egg in the yet diminutive and tender germ of 

 various leguminous cerealia, of the coffee-tree, palms, &c., where the larva 

 lives and is metamorphosed. To obtain an issue the perfect insect detaches a 

 portion of the epidermis in the form of a cap, thus producing those holes but 

 too often found in peas, beans, dates, &c. The perfect insect is taken on 

 flowers. 



The labrum is apparent, the anterior elongation of their head short, broad, 

 depressed, and in the form of a snout ; the palpi are very visible and filiform, 

 or larger at the extremity. 



B. pisi, Lin. Length two lines ; black ; base of the antennae and part of the 

 legs fulvous ; elytra dotted with grey. A very noxious little insect, that in 

 certain seasons has occasioned much damage in North America. 



Those, in which the three or four last joints are united into a club, form the 

 genus 



ATTELABUS, Linn&us. 



They attack the leaves or most tender parts of plants. Most of the females 

 roll up these leaves into a tube or cornet, in which they deposit their eggs, 

 thus preparing a domicil for their young ones, which also furnishes them with 

 food. 



Those in which the antennae are filiform, or where the last joint alone forms 

 the club; where the proboscis, frequently longer in the males than in the 

 females, and often differently terminated, always projects forwards ; in which 

 all the other parts of the body are usually much elongated, and the penultimate 

 joint of the tarsi is bilobate, form the genus 



BRENTUS. 



These insects are peculiar to hot climates. Their body is linear, and the 

 antennae, filiform or slightly enlarged towards the extremity, are composed of 

 eleven joints. 



Sometimes the antennae are distinctly geniculate, the first joint being much 

 longer than the following ones. They form the genus Curculio of Linnaeus. 



We will divide them into the Brevirostres and the Longirostres, according 

 as the antennae are inserted near the extremity of the proboscis, and even with 

 the origin of the mandibles, or further back, either near its middle or close to 

 its base. 



The Brevirostres of this naturalist, according to the system of Fabricius, are 

 divided into two genera. 



BRACHYCERUS, 



Where all the joints of the tarsi are entire and without brush or pellet beneath. 

 Their short and but slightly geniculate antennae present externally but nine 

 joints, the last of which forms the club. They are destitute of wings, and
