COLEOPTERA. 509 



They may be united in the single genus 



Calandra, 



Which may be divided into six subgenera. 



The two first are apterous, and present, as well as the preceding 

 and following ones, the last excepted, four joints in all the tarsi, and 

 of which the penultimate is bilobate. The antennse are geniculate 

 and inserted at but a little distance from the middle of the proboscis. 



In the first or 



Anchonus, Schoenh. 



These organs present nine joints before the club. The tenth, and 

 perhaps two others, but intimately united with the preceding one, 

 and but little distinct, form a short ovoid club. 



In the second 



OrthochjEtes, Germ.(l) 



It is the eighth which forms the club, the figure and composition 

 of which appear to be the same as in Anchonus. 



The other four subgenera are 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, are longer than the others(2). In 



Calandra properly 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 granarius, 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), is the destroyer of our granaries. 



C. oryzoe; Curculio oryzfe, 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-
