EXPLANATION OF PLATES 



These drawings were made from enlarged photographs on which the lines 

 desired were traced, the picture then erased, and the line drawings thus produced 

 were again enlarged by photography. This explains a slight lack of symmetry, 

 in some of the figures, due to difficulty in getting the insect exactly posed.
