82 INSECTA. 
the four anterior tarsi appear to consist of five joints, form the genus 
Rurosmmus, 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 antennze and eyes, have but four joints 
to all the tarsi and the penultimate bilobate, re-enter that of 
Anrurisus, Geoff., Fab.* 
To which may be united the Riinomaceres of Olivier t. These 
Insects are usually found in old wood—others live on flowers. In 
Brucuus, Mab., Oliv.—Myuasris, Geoff., 
Or Bruchus proper, the antenne are filiform, and frequently ser- 
rated or pectinated ; the eyes are emarginated. 
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, &c.} 
The perfect in taken on flowers. 
B. pisa, L.; Oliv., Col. 1V, 79, 1, 6,a,d. Length two lines; 
black ; base of the antenne 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§. The 
Ruzsus, Fisch. 
Is distinguished from Bruchus by the flexible elytra and bifid 
hooks of the tarsi ||. The 
Xyxtopuiuus, Bonnell, 
Is removed from it by the palpi, which are clavate 4. 
The others have no apparent labrum; the palpi are extremely

Anthribus latirostris, varius, scabrosus, Fab. 
+ Oliv., Col. V,87. The Rhino. lepturoides, atelaboides, Fab. The penultimate 
joint of the tarsi is not between the lobes of the preceding one, a circumstance which 
distinguishes them from Anthribus. 
{ 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 
its characters. In so concise a work as this, it is impossible for me to give all the 
generic, or subgeneric sections of M. Schcenherr, without stepping beyond my pre- 
scribed limits. 
§ For the other species, see Fabricius and Olivier, Ibid. The B. rufipes of the 
latter, so common in the vicinity of Paris on various species of Reseda, forms the 
geuus Uroden of Scheenherr. The antennz terminates in three thicker joints, form- 
ing a club.
