ATTRACTION OF MOTHS DY ELKCTUIC LIGHT IN SWITZERLAND. 265 



in their emergence, and the sudden advent of warm weather bringing 

 out the species then due, caused a great rush of insect life at this time. 

 In regard to abundance of each species, where no remark is made ; it 

 may be understood that it was present in average numbers, when 

 specially abundant, on the contrary, I have noted the fact. On two 

 subse(j[uent nights in the same week, after I had left Aigle, Mr. Von 

 Veith visited the electric light, and added a few new species to the list 

 (to these I have put the dates), besides many more of those we had taken 

 at the earlier dates.

Thus was completed a record of over a hundred spjcies actually

 to refrain, as the larger moths knocked them to pieces in the bottle,
