peculiar to those just emerging from the ground. So uniform were they 

 in this respect as to lead us to suspect that they could not be plum cur- 

 culios, while curculios caught in Mr. Whittlesey's grounds, in the act of 

 puncturing fruit, were darker colored, looking like those taken farther 

 south. 



Attention to the suggestions we have made would aid in clearing up 

 several mooted points concerning the habits of the curculio, as well as 

 furnish accurate data on which to base future operations. 



All our orchard ground has been thoroughly stirred, and cobs or 

 other traps will be placed around all the trees early in April. And we 

 advise all to devote time to this means of trapping. Do it early and 

 thoroughly, and report results. But at the same time be sure to have a 

 curculio catcher ready in case of need. 



We will cite only a single case, though numerous others could be 

 adduced, showing how rapidly curculios increase and advance upon new- 

 territory : 



We recently inquired of Mr. B. Pullen, one of the most extensive 

 and successful peach growers of Centralia, 111., with respect to the sea- 

 son's catch of curculios at that point. He informed us that most of the 

 orchardists united for the purpose of capturing these insects, some run- 

 ning as many as three catchers. His own orchard the previous year was 

 barren of fruit, or nearly so; but notwithstanding this, from his own 

 trees upwards of 70,000 curculios had been numbered as the product of 

 this season's run. 



GRAPE CODLING. 



Among the insects injurious to the vine, which have within the past 

 few years become numerous in most, probably all, of the large vine dis- 

 tricts of the West, none have spread so rapidly, or appear to be so 

 little known, as the Grape Codling. 



During the past few years we have repeatedly visited vineyards in 

 which twenty, antl in some as high as fifty per cent, of the grapes were 

 spoiled or had rotted from injuries clearly traceable to the work of these 

 insects; and that too, without its presence being suspected, the proprietors 

 generally supposing that the damage was to be attributed to rot. At the 

 meeting of the Mississippi Valley Grape Growers' Association, held at 

 St. Louis the past spring, it was stated by prominent vineyardists that 

 the ratio of increase of these Grape Codlings was 25 per cent, per 

 annum ; and that up to that time no parasitic insect or other natural check 

 was known to have appeared to materially interrupt their regular increase. 

 A nuinber of years since we read a paper before the Missouri State Hor- 

 ticultural Society, in which we referred to the codling moth having become 

 domesticated in the okler vineyards around Alton, apparently being as 

 much at home in grapes as in apples. 



At that time, and until the editors of the American Entomologist 

 decided differently, we had no doubt that the larvae found in grapes and 

 those in apples were one and the same insect.
