168 THE CANADIAN ENTOMOLOGIST. 



the same thing over again. An individual performed three times in succes- 

 sion, and then another ah'ghted on the ground by its side ; they ran by 

 each other several times, apparently clasping, probably in conflict, for I 

 am quite sure they were both males. At last one of them flew away, and 

 the other soon after renewed the performing. I regret to say that I did 

 not capture specimens to ascertain the sex ; but, judging from size, I do 

 not think I have ever seen any but the males taking active part in these 

 aerial exhibitions. In going through with the performance they rise at 

 first generally about three or four feet, making a light purring or beating 

 sound, and then, rising higher, change the motion of the wings, when a 

 curious, sharp, see sawing sound is produced. Some rise even higher than 

 six feet in the last act ; others rise only one or two feet. Of course some 

 excel others in the beauty and ease with which they accomplish the feat ; 

 many do not remain in just the same place while hovering, but vary, falling 

 or jerking about while endeavoring to keep the same point in the air. I 

 am of the opinion that the females are sensitive to the grace with which 

 this is performed. 



THE CROTON BUG IN QUEBEC PROVINCE. 



BY REV. THOMAS W. FYLES, SOUTH QUEBEC. 



One morning last November I went to the Chaudiere Curve, to meet 

 the train from Halifax, which had been delayed for some hours. I found 

 two men in the waiting-room who had spent the night there. They com- 

 plained that swarms of black beetles had troubled them all night so that 

 they could not sleep. Upon my questioning the correctness of the state- 

 ment, they said, " Well, here they are in all the cracks," and they forth- 

 with commenced to poke the creatures out. The insects were numerous 

 enough, but they were not beetles, nor were they black. They were 

 specimens of the German Cockroach, Ectobia Gennanica. I afterwards 

 enquired of one of the railway employes as to the time of the first appear- 

 ance of the insects. The man told me that he first noticed them in 1882. 

 I asked if they had appeared anywhere else in the neighborhood. " Yes," 

 he answered, " in my own house last winter ; but," he added, " I am not 

 there in the day time, so I left the windows open and froze them out." 



The enquiry is interesting, How did Ectobia Germmiica get to the 

 Chaudiere? At that place, which is nine miles from Point Levi,
