Western N. America. C. R. Osten Sacken, Bull. U. S. Geol. Surv. iii. 
pp. 349-354, in some remarks on the Diptera of California, discusses in a 
general way the distribution of the Insecta in the N.W. States. The 
Rocky Mountains do not form a natural boundary for a distinct ento- 
mological fauna. The real dividing point is the line (somewhere about 
long. 98'’) of summer dryness, where agriculture becomes precarious 
without artificial irrigation. Northwards, this region extends until 
circumpolar forms occur ; southwards, until a tropical fauna commences. 
The author's observations bearing on the analogies of the Western 
American fauna with those of Europe and Asia, and on other connected 
points, deserve careful attention.
