A New Method for Studying Venation. 

 By Alfred P. Hall. 



During the pa.st winter while studying the venation of Lep- 

 idoptera, I felt the need of a method for preserving the rfesults 

 in compact form for ea.sy comparison. Mounting on glass was 

 much too bulky for my purpose, and after several experiments 

 I hit upon a method that seems to meet all the requirements, 

 which ])(jsse.sses the merit of simplicity as well This method 

 being new to several entomologists to whom it has been shown, 

 it occurred to me that it might be of interest to other collec- 

 tors as well, and herewith give directions which are easily fol- 

 lowed by any one. 



The wings are first moistened willi alcohol and then put in

 then removed to fresh water for five or ten minutes to remove 

 tlie lime solutioji, thus preventing deposits in drying. Remove 

 the wings by immersing a piece of paper in the water and float- 

 ing the wing uikmi it, much in the manner of mounting sea 

 weeds. The i)aper and wings are then removed together and
