cover glasses and then placing in an enlarging camera with a 

 300-watt light and reflector, the image being thrown upon a 5 x 7 

 plate. This gives a sharp image from which prints may be made 

 the same as with direct photography. Photographs have been 

 made of the wings of more valuable specimens by placing them on 

 a sheet of white paper and making the exposure. In photograph- 

 ing mounted labia in balsam or damar, it is advisable to use a 

 color screen, preferably a yellowish green or light brown. 



Drawings may be made with the aid of an ocular net microm- 

 eter and cross-section paper, allowing each square of the cross- 

 section paper to correspond to a square of the net micrometer 

 placed in the ocular of the microscope. A few photographic trac- 

 ings have also been made, the image being bleached out after ink 

 was applied. The camera lucida is also useful in making illustra- 

 tions, and there are other mechanical devices which aid materially 

 in the process. All of them, however, must be supplemented by 

 some personal efforts, for otherwise satisfactory results will not be 

 obtained.
