vegetables, useful or necessary to man, and feed on their paren- 

 chyma. 



BRUCHUS, Lin. 



In Bruchus proper, the antenna 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 fili- 

 form, or larger at the extremity. 



B. pisi, L. 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, Lin. 



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 Curcullo 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.
