satisfactory except in the blossoming season. The boring was worst at the base and 

 seldom extended further up than eight or nine feet. Stems less than 21/2 inches 

 in diameter were seldom, if ever, touched. Those of 5 inches in diameter seemed 

 the favorite resort, and occasionally stems eight and nine inches in diameter 

 were badly bored, but not trees of greater thickness than this. The damage was 

 observed over more than a mile of country between south and north, and half a 

 mile between east and west. In the Avest area the willows were riddled with 

 holes, and trees that had five or six stems growing out from the roots had (nearly 

 all) lost some of these, either snapped off above by the wind or broken down by 

 their own weight at the base. More than once in crossing the stream I broke 

 off a thick stem by simply bearing on it with my hand. On returning to Peter- 

 borough after Thanksgiving I went through twenty or thirty collections of insects 

 made by pupils of the school, and in one located a single specimen of the beetle. 

 So far I have not found any damage to willows in our neighborhood. 



While I was in Toronto (between July 3 and July 24) Dr. Watson captured 

 a large number of Urographis fasciaia on a felled oak as well as on a neighboring 

 woodpile of the same material. On the log he saw also, but failed to capture, some 

 specimens of Ncoclytus e.rntlirocepliahis. They are extremely quick in their move- 

 ments, especially during hot sunshine. Two days snatched from the holocaust of 

 July, I managed to spend at Queenston and made a number of interesting captures 

 between there and Niagara Glen, mostly about blossoms of Xew .Jersey Tea. I 

 have a list of these but will not trespass further on your time and patience.

Early in August I took another specimen of Eup. suharmalii.s, always on 

 basswood; and throughout August in the Algonquin Park found Lepiura canadensis 

 common — none of them males. 



On returning to Peterborough in September, I found the climbing nasturtium 

 on our verandah-railing badly infested with larva' of Pieri<t rapa'. In a few 

 minutes I picked about 100 off the leaves over a space of about six feet. On each 

 of the two following days I gathered almost as many. I suspect they came from 

 a vacant field, nearly opposite, in which charlock lias been allowed to grow. They 

 were succeeded in October by black aphids from a neighbor's dahlias. These 

 multiplied so on a thick stem that had twined about the verandah post that it 

 resembled a ship's mast coiled round with a spiral of tarred rope.

As Mr. Caesar in his report on " Insects of the Season in Ontario " will no 

 doubt refer to most of the common pests found in the Niagara district, I shall 

 confine my attention to a few insects which were of special interest to me.
