north temperate zone, and seems scarcely to reach the southern bor- 

 der of the United States; the only species of true DoHchopus known 

 by me to occur farther south are myosota in North Sonora, near the 

 Arizona line, and an undescribed species, mentioned by Osten Sacken 

 in the sam» connection, from Durango ; but the latter is known to be 

 Alpine (8100 ft.) I have examined large collections of West Indian 

 and South American material without finding the genus. 



I am indebted to the University of Kansas for the opportunity to 

 work up her excellent collection (indicated in the article by U. K.); 

 to Dr. Williston for books and other assistance ; to C. W. Johnson, 

 D. W. Coquillctt, and others for material contributed.
