very close together. It is entirely black and sparsely sprinkled 

 with whitish hair, and is about half an inch in length. 



The third cureulion, the Mecinus Circulatus has the antennae in- 

 serted in the middle of the rostrum or proboscis. The antennae is 

 five-jointed, the first very long and conical, the others transversal 

 and short, the club oval and nearly solid. Rostrum not very 

 long, strong, slightly inclined, cylindrical and not dilated at the ex- 

 tremity. Body oblong, cylindrical and winged. Thorax cylindri- 

 cal and much compressed in front. Shield triangular, paws or feet, 

 hard and inserted very near together. The shield wing elongated 

 and cylindrical. The tarsi spongy beneath the first two joints, tri- 

 angular, penultimate expanded and the last one elongated and 

 cylindrical. 



This insect is a trifle more than one-twelfth of an inch in length. 

 Chestnut colored with stripes of a lighter shade along the edges of 

 the shield wings and about the head. The feet are dark, as are also

The three above described curculions in their last stage attack 

 the buds of the tender branches, and gnaw the shoots at the forks,

 deposits her eggs and the resulting larvae imitate the habits of the 

 Phlcetribus whose description follows.
