465] COLORS OF TIGER BEETLES— SHELFORD 71 



EXPLANATION OF PLATES 



Because of the diversity of material studied, the plates of this 

 monograph have been made in different ways and for details and excep- 

 tions to the general statements below it will be necessary to see the text. 

 Plates I to IV show camera drawings made chiefly by mounting dry 

 elytra in hot balsam containing little or nonei of the usual solvents. 

 Plate V is a diagram. Plates VIII to XI were made from specimens 

 killed in the best of fixing fluids and mounted according to approved 

 methods. They represent different individuals chosen at different 

 stages, but have been checked with individual histories. Plates VI, VII, 

 and XII to XXVIII, in so far as they are concerned with elytra, are 

 made up of free-hand drawings of elytra as seen from directly above 

 the center of the curved side, i. e. to the left and above the specimen. 

 The specimens represented are from various sources. All are drawn 

 the same size though the specimens vary greatly. The drawings in 

 plates XII to XVIII are about twice the natural size of an average 

 species. The distribution data shown were supplied from various col- 

 lections and printed lists. The colored plates which show color ontogeny 

 were made chiefly from the same living individual.
