82 INSECTA. 



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 Avhich, with similar antennae and eyes, have but four joints 

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



Anthribus, Geoff., Fab. * 



To which may be united the Rhinomaceres of Olivier f . These 

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



Bruchus, Fab., OHv. — Mylabris, Geoff., 



Or Bruchus proper, the antennae 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.J 

 The perfect in taken on flowers. 



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

 black ; base of the antennse 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 



Rhjjbus, Fisch. 

 Is distinguished from Bruchus by the flexible elytra and bifid 

 hooks of the tarsi ||. The 



Xylophilus, Bonnelli, 

 Is removed from it by the palpi, which are clavate •[[. 



The others have no apparent labrum ; the palpi are extremely

t Oliv., Col. V, 87. The Rhino, lepfuroides, atel aboid es, Fah. The penultimate 

 joiot of the tarsi is not between the loljes of the preceding one, a circumstance which 

 distinguishes them from Anthribus. 



X 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. Schoenherr, without stepping beyond my pre- 

 scribed limits. 



§ For the other species, see Fabricius and Olivier, Ibid. The jB. nifipes of the 

 latter, so common in the vicinity of Paris on various species of Reseda, forms the 

 geuus Uroden of Schoenherr. The antennae terminates in three thicker joints, form- 

 ing a club.
