272 ENTOMOLOGICAL SOCIETY 



Switzerland, and upper Austria and everywhere the foliage of 

 the grape presents the characteristic bluish-white effect of the 

 Bordeaux wash. Spraying for insects, or other treatment, does 

 not often present any visible indication, and is, for the most part, 

 at other seasons and diverse in methods, such as the treatment 

 for the Phylloxera and the various vine and fruit worms. 



From France the writer passed rapidly through Switzerland 

 into northern Italy, and thence through the Austrian Tyrol 

 and Bavaria to Munich, and later to Vienna, making some stops 

 between. Little, in an entomological way, was accomplished 

 during this portion of the trip, excepting that derived from famil 

 iarity gained with the forest conditions and growth, the character 

 istic fruits and methods of culture in the districts passed through. 

 As noted elsewhere, the summer of 1897 was an exception 

 ally unfavorable one for insects, and throughout this region no 

 insect damage of any moment to either cultivated plants or forest 

 trees was observed. Occasionally, especially in the Inn Valley, 

 many trees were seen banded with insect-lime, and, later, similar 

 applications were noted in some of the large royal domains or 

 parks in Bavaria, but in no case did there appear any special 

 reason for this banding, nor any evidence of damage from larvae, 

 and, furthermore, if there had been occasion for its use. the lime 

 would have been utterly worthless as a protection against insects, 



because it had hardened and could offer no barrier whatever to 



i 



the passage of larvae over it. It was not surprising, therefore, to 

 learn at Vienna that tree-lime is far from being generally esteemed, 

 and that many intelligent entomologists deem it comparatively 

 worthless, or a " mere fad." It is a new remedy, having been 

 used to any extent in Austria only during the last three or four 

 years. 



At Innsbruck the writer had the pleasure of seeing Professor 

 Dalla Torre, whose voluminous catalogues of the Hymenoptera 

 have made him well known on this side of the Atlantic. He is 

 connected with the K. K. Leopold-Franzens-Universitat as assist 

 ant professor of zoology, and is a vigorous middle-aged man, 

 most energetic in habits, and evidently a prodigious worker. A 

 very pleasant half day was spent in his rooms, looking over his 

 work and discussing entomological matters with himself and wife, 

 who takes a keen interest in the science.
