the same condition of fruit at a well known nursery; even the 

 Duchesse pears almost totally destroyed. This fruit enemy 

 seems yet confined to localities, but is spreading rapidly." 



This beetle was first briefly described by Mr. Walsh in a note 

 in the Prairie Farmer for July 18th, 1863, p. 37, from speci- 

 mens found by him on the hawthorn, but until I bred it this 

 spring nothing was known of its larval history. It is a some- 

 what larger insect than the Plum Curculio, has a compara- 

 tively longer snout, and is very broad shouldered; thus 

 tapering just the opposite way to the Apple Curculio. Its 

 general color is a tolerably uniform ash-gray, mottled more or 

 less with ochre-yellow, dusky and whitish, and it has a dusky 

 somewhat triangular spot at the base of the thorax above, and 

 seven distinct narrow longitudinal elevations on the wing- 

 oovers, with two rows of punctures between each. 



This beetle differs further from the others, in the fact that 

 it does not appear, even in the latitude of St. Louis, till about 

 the first of June, and I have had its larvae of the previous 

 year in the gi'ound in May, when the newly hatched larvae of 

 the Plum Curculio were already Avorking destruction in the 

 fruit. In some of the more Northern States it would not 

 appear till the middle of July. 



ITS TEANSFORMATIONS AND HABITS. 



This snout-beetle does not make a crescent like the Plum 

 Curculio ; but, like the Apple Curculio, makes a direct punc- 

 ture for the reception of its Qg^, the hole being somewhat 

 larger than that of the latter, and the bottom of the cavity 

 similarly enlarged and gnawed, so as to form a neat bed for 

 the Qgg. The egg is very similar to that of the Plum Curcu- 

 lio, and hatches in a few days after being deposited. In all 

 probability it also swells and enlarges somewhat before hatch- 

 ing. The larva works for the most part near the surface of 

 the fruit and does not enter to the heart. It is of the general 

 form of that of the Plum Curculio, and differs principally in
