"I. Eastern Hemisphere, with 28 species. 
-A. Circummediterranean District, with 19 species. 
1. European Province, with 15 species. 
2. African Province, with 3 species. 
3. Asiatic Province, with 5 species. 
" B. Asiatic District, with 9 species. 
1. Western Siberia, with 1 species. 
2. Eastern Siberia, with 2 species. 
8. Japan, China, Siam, with C species. 
- II, Western Hemisphere, with 57 species. 
A. Pacific District, with 25 species. 
1. Northern Province, with 15 species.

B, Atlantic District, with 32 species. 
1, Province West of Mississippi, with 13 species. 
2. Province East of Mississippi, with 28 species. 
With regard to the distribution of the genera^ nine are peeuliar
