Cycros Trap. 



I was very much interested in read- 

 ing the article in the September num- 

 ber entitled "A Carrion Route," by 

 F. P. Drowne. Some ten or more 

 years ago, when I was collecting for 

 my father. Dr. A. W. Hoffmeister, 

 whom perhaps some of the older col- 

 eopterist will remember, I had a little 

 experience, somewhat in the line of Dr. 

 D. We trapped the Cycrus in almost 

 the same way as did Mr. D. the Car- 

 rion Beetles. Thinking perhaps the- 

 method I employed will be of some 

 interest to the Doctor as well as ta 

 other collectors, I will relate how I 

 snared these beetles, which were then 

 in great demand by some collectors 

 and for which we got as high as fifty 

 cents apiece. 



In the first place I collected a lot of 

 Snails, which were quite plentiful near 

 a stream of running water. Then I 

 procured some quart fruit jars into 

 which I placed some Snails an inch or 

 two high, according to the quantity of 

 Snails I had, placing over them some 

 wire screen so they could not crawl 

 out of the jars, a few Snails were 

 placed on top of the screen, and my 

 trap was baited. These bailed jars 

 were buried or sunk into the ground, 

 so the top was even with the surface, 

 in a willow grove, in a marshy place 

 near the river. A large piece of bark 

 or other rough decayed wood was 

 loosely placed over same and the trap 

 was set. 



The Cycrus being very fond of 

 Snails would soon find their way into 

 the jars where they were held prison- 

 ers from which they were easily trans- 

 ferred to the collecting bottle. Often- 

 times I have found as many as a dozen 

 and a half in a single jar at one time. 



The larger of the two kinds ("the 

 names I do not remember) I caught 

 were the most numerous. Besides 

 these I would catch many other kinds 

 of beetles in the same jars.
