APION VORAX. 



Among the very small insects which damage the olive there arc 

 three curculions, two of the Apion genus and a third of the Mecinus. 



The first of the Apion kind, has the antennas, eight-jointed; the- 

 first joint is long and conical, the second a trifle shorter, the third 

 still shorter than the second and the remaining five are very short, 

 gradually broadening towards the extremities into a solid pointed 

 club. The rostrum, cylindrical and arched, jaws short, eyes lateral,, 

 protruding and round. Thorax conical, body curved and convex, 

 compressed anteriorly. 



Winged, shell very small and pointed, shield wing ovoid, larger 

 at the base than the thorax, jaws elongated and truncated, femora 

 puffed out, tarsi spongy beneath, with the first two joints conical, 

 penultimate expanded, heart-shaped and bifurcated, the last cylin- 

 drical, enlarged at the extremity and furnished with two hooks. 



The insect is about half an inch in length, body blackish, thorax 

 gray on upper part, shield wing ridged with blackish green, sjmrsely 

 sprinkled with dirty white hair, femora deep yellow, tarsi gray.

 first joint of the antennas somewhat longer, the second shorter than 

 the first, and the other six so short as to be almost globular ; the 

 rostrum less arched, the hind legs having a sort of stinger or tooth, 

 The last joint of the tarsi rather long and cylindrical, with the feet
