arranged in a curve equidistant from the eye. The head is also provided with one 

 pair of distant setse on vertex. Antenna3 geniculate, clavate and quite long. The 

 thorax is dorsally characterized with 

 a pair of lateral very prominent 

 setigerous tubercles. On the front 

 margin between these tubercles are 

 two pair of small setee. A very fine 

 hair also arises at the base of each 

 large tubercle. About the middle 

 are two distant setigerous tubercles 

 which form with two sublateral 

 tubercles a semi-circle. Mesotho- 

 rax between the elytra provided with 

 two setigerous tubercles. Meta- 

 thorax also provided with a pair of 

 tubercles which are farther apart 

 than those on the mesothorax. First 

 seven abdominal segments with 

 three pair of dorsal setigerous tub- 

 ercles on each segment, arranged so 

 that they make six longitudinal series 

 of tubercles. In addition to these 

 dorsal tubercles, each segment is 

 provided laterally with several tub- 

 ercles. Eighth dorsal segment with 

 only four tubercles. The ninth seg- 

 ment is the apical segment dorsally. 

 This is provided at its outer corners 

 with two long inward curving pro- 

 cesses which are semi-acute at apex. 

 Ventrally the body is not provided 

 with tubercles nor setse except near 

 the base of the sides of the ninth seg- 

 ment. At these places are to be 

 found the longest seta3 of the body. 

 The arrangement of the ventral 

 folds of the last segments is better 

 described by means of the accom- 

 panying illustration, than can be 

 stated in words. Each femur is 

 apically armed with three setse.

Imported Fruit Bud Weevil 

 This weevil is one of most recently discovered importations. 



Two 



specimens have been examined which were collected in Marion Co., 

 Indiana. In Italy this species is quite injmious as an adult to the 

 buds and foliage of fruit trees, especially the pear, and is also found on 

 plum, hawthorn (Cratcvgus oxyacantha), beech, and dogwood (Cornus
