In concluding his memoir (/. c. pp. 140-141), the author 
indicates that, although his classification is founded upon the 
European species, it will be applicable with but little alteration 
to the whole genus. His groups for the arrangement of all the 
species, including the exotic forms, are as follows : — 
I. Eyes elongated, slightly convex, distinctly facetted. Divisions as above. 
Division I. includes Burmeister’s Division III. of Brazilian species, and Divi- 
sion II. his second division. 
II. Eyes in both sexes circular, very smooth and convex, =Burmeister’s 
Division I.
