THE CANADIAN ENTOMOLOGIST 133 



lector who would profit by the salvage of the shore-line would, 

 therefore, do well to pay careful heed to season and to weather. 

 After conditions favourable for swarming accompanied by off- 

 shore winds, then let him search a low, sandy beach on a lee shore. 

 It is doubtful whether there is any other place where specimens 

 ma>- be accumulated so easily and in such variety. Schwarz 

 (1889) records that he and Hubbard in four days collected more 

 than 1,100 species of beetles on the shore-line of Lake Superior 

 at a time when the collecting there was not at its best. The 

 Lepidoptera of the drift-line, to be sure, are worthless as specimens; 

 most of the Coleoptera, however, are good enough for the cabinet, 

 and insects of other orders are often in good condition. 

 What The Drift-line Offers. 



Besides the vegetable debris brought down by woodland 

 streams, the cinders and straw and other waste contributed by 

 lake steamers, the dead vertebrates such as fishes and birds, a few 

 of which are always present, and a few miscellaneous invertebrates 

 — shells of mussels and snails or occasionally whole specimens of 

 Gammanis fasciatus — there are always many insects present in 

 the summer season. There are far more kinds of them than may 

 profitably be listed here; but it may be worth while to mention in 

 each of the orders,. the forms most abundantly found in the drift- 

 line, as indicated by my collections through the summer of 1906, 

 during which season I collected merely a sample of the insects 

 present whenever the collecting from the beach was good. 



Coleoptera are by far the most abundant insects of the drift. 

 My specimens, 2,248 in number, as determined for me by Mr. 

 Herbert Morrison, represented 26 families and 127 species. The 

 species that were represented by more than ten specimens, the date 

 of principal occurrence, the number of specimens found on that 

 date and the total number of each are as follows:
