170 ENTOMOLOGICAL NEWS. [June, 



jar the frame and slide door can be soldered to any tin lid to 

 slip tightly over or into any kind of a jar, so that any collector, 

 by slight modifications, can adapt it to his favorite jar and net 

 handle. 



To use this device I simply remove the net from the handle 

 and replace it with the clamp " b," insert one of my cyanide 

 bottles and clamp it tightly by turning thumbscrew " d," then 

 put on my lid and it is ready for use. Holding my net handle 

 close to the end with my right hand, with my left I pull the 

 string until the slide door is wide open ; (the stop " g " pre- 

 vents it being pulled entirely out of the slide); then I slip the 

 string between the first finger of the right hand, and, the net 

 handle pressing firmly on it, this holds the trap open until I 

 have placed the mouth of the jar over his "mothship," and 

 as soon as he flies out into the jar release the string and the 

 lid will slide up and imprison him. 



I used this with the most gratifying results last summer, not 

 only on those that were too high to reach with bottle in hand, 

 for which I had designed it, but equally desirable for those 

 near the ground or on the ground, as, being enabled to remain 

 several feet from them, I had no trouble in capturing the most 

 wary, even in the hottest days. For Catocalae I consider it 

 invaluable , and extremely desirable for all Heterocera. 



Should any of the readers of this have any difficulty in get- 

 ting one made from this cut and description I shall be glad to 

 give any further details on application, only please do not ask 

 me to make them for you, as bugs are here and I am busy. A 

 tinner can make you one.

 Prof. Levi W. Mengel of Reading, Penna. , very kindly sub- 

 mitted to me for study a small collection of butterflies made by 

 the late Mr. Irvin Runyeon of Reading. Mr. Runyeon made
