496 INSECTA. 



Bruchus, Lin. 



Which is subdivided as follows: 



Those species in which the antennae are clavate, or very evidently 

 larger at the extremity, where the eyes are unemarginated, and 

 where the four anterior tarsi appear to consist of five joints, form 

 the genus Rhinosimus, which, agreeably to this character, we have 

 placed among the Heteromera, but which is allied to the following 

 subgenus by many others. 



Those which, with similar antennae and eyes, have but four joints 

 to all the tarsi and the penultimate bilobate, re-enter that of 



Anthribus, Geoff. Fab. (1) 



To which may be united the lihinomaceres of OUvier(2). These 

 Insects are usually found in old wood — others live on flowers. In 



Buucpus, Fab. Oliv. — Mylabris, Geoff. 



Or Bruchus proper, the antennae are filiform and frequently ser- 

 rated or pectinated; the eyes are cmarginated. 



The anus is exposed, and 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, Ecc.(3) The perfect Insect is taken on flowers. 



B. pisi, L.; Oliv., Col., IV, 79, 1, 6, a, d. Length two lines; 

 black; base of the antennae and part of the legs fulvous; elytra 

 dotted with grey; a whitish cruciform spot on the anus. 



A very noxious little Insect, that in certain seasons has occa- 

 sioned much damage in North America(4). The 



(1) The Macrocephala, Oliv., Col., IV, 80; the Anthribes, Nos. 1—3, of Geof- 

 froy — Anthribus latirostris, varius, scabrostts, Fab. 



(2) Oliv., Col. V, 87. The Rhino, lepturoides, atelaboides. Fab. The penulti- 

 mate joint of the tarsi is not between the lobes of the preceding one, a circum- 

 stance which distinguishes them from Anthribus. 



(3) These habits are also common to certain small species of Anthribus. 



I have not noticed the genus Rhimaria of Kirby, because I have no precise idea 

 of it characters. In so concise a work as this, it is impossible for me to give all 

 the generic, or subgeneric sections of M. Schoenherr, without stepping beyond my 

 prescribed limits.
