Sept., I9I2.] Miscellaneous Notes. 195 



The bottles were in the ground a full week and then I journeyed to 

 Eagle Rock anxious to see if my experiment had proved a success. 

 The first bottle examined contained several Geotrupcs and a number 

 of common Carabidcc and I was much pleased and knew at once that 

 my hopes would be more than realized. Every bottle examined con- 

 tained from one to six or eight Geotrupcs in addition to a number 

 of other species. One contained a mouse in an advanced stage of de- 

 composition and in that bottle I obtained a number of Nccrophorus 

 toniciitosits. After examining the contents of each bottle carefully 

 it was rebaited and left to be looked at the following week. 



In all I made three trips to gather the specimens, viz. September lo 

 and 17 and October 8, and as I had then collected as many of the 

 Geotrupcs splcndidiis as I could handle, in addition to numerous other 

 specimens, did not care to continue the experiment further. In all 

 several hundred beetles were taken, of which the following species 

 were the most interesting to me: Geotrupcs splendidiis, of which I 

 took in all 80 specimens, Geotrupcs egcrici, Myas coracinus, and 

 Cyinindis cribricollis. 



The bottles containing the condensed milk proved to be the most 

 attractive and contained the greatest number of beetles, most of which 

 were dead when examined but in good condition. In the bottles with 

 earth in the bottom the Geotrupcs had buried themselves in the dirt 

 and were alive when taken and the bottles containing the syrup had 

 only a comparatively few insects in them. 



In baiting for beetles near Washington, D. C, I have always 

 found the sugaring material by far the best bait and have abandoned 

 the use of condensed milk entirely. — Ernest Shoemaker.

It is always a pleasure to see a needed piece of work well done, 

 and probably there is nothing more desirable at present than a re- 

 vision of the world's genera of Geometrida?, and certainly it could not 

 have been better executed than by ]Mr. Louis B. Prout in Genera 

 Insectorum.
