It is the eighth wliich forms the club, the figure and composition of 

 which appear to be the same as in Anchonus. 



Tlic other four sul)gcnera arc furnished with wings. 



In the three following ones the tarsi consist of but four joints, the 

 penultimate of which is bilobate. 



Rhina, Lat. — Lixus, Fab. 



The antennae are strongly geniculate, and inserted near the middle 

 of the straight, projecting proboscis, their eighth joint forming a 

 highly elongated and almost cylindrical club. The anterior legs, at 

 least in the males, arc longer than the others f. In 



Calandra, jjroper/y so called, 



The antennae are strongly geniculate, but inserted near the base of 

 the proboscis; their eighth joint forms an ovoid or triangular club. 



C. granaria; Curculio granartus, L., Oliv., Col. V, 83, xvi, 

 196. But too well known; its body is elongated and brown; 

 thorax as long as the elytra, and punctured. Its larva, known by 

 the name of weevil (genre J, is the destroyer of our granaries. 



C. oryzce; Curculio oryzce, L.; Oliv., lb., VII, 81. Similar 

 to the preceding, but with two fulvous spots on each elytron. It 

 attacks rice. 



C. palmarum; Curculio palmarum, L.; Oliv., lb., II, 16. 

 Length an inch and a half; club of the antennae truncated; en- 

 tirely black, with silky hairs at the extremity of the proboscis. 

 It lives on the pith of the Palms of South America. The inha- 

 bitants of that country consider its larva, called the ver-palmiste, 

 as a great delicacy J. 



In the fifth subgenus, or 



CossoNUS, Clairv., 



We observe antennse hardly longer than the head and proboscis, with 

 eight joints anterior to the club. They are stout, and inserted near 

 the middle of the proboscis §. 

 The last or 



Dryopthorus, Schcenh, — Bulbifer, Dej., 



With respect to the tarsi is anomalous. They consist of joints, 

 neither of which is bilobate. The antennae have but six joints, the 

 last forming the club i|.
