The studies underlying this paper are based upon specimens in the 

 collections of the United States National Museum, Washington ; the 

 Academy of Natural Sciences of Philadelphia; the American Museum 

 of Natural History, New York; the Boston Society of Natural History; 

 the Museum of Comparative Zoology, Cambridge, Mass.; the field 

 laboratory of the U. wS. Bureau of Entomology and Plant Quarantine 

 at Melrose Highlands, Mass.; and of Prof. C. T. Brues, of Harvard 

 University. I am indebted to these institutions and to Professor 

 Brues for the loan of specimens and to A. B. Gahan and C. F. W. 

 IMuesebeck, of the U. S. Bureau of Entomology and Plant Quaran- 

 tine, for manj'^ helpful suggestions and for criticism of the manuscript. 

 My thanks are also due Nathan Banks, of the Museum of Compara- 

 tive Zoolog}^, and D. L. Parker and P. B. Dowden, of the Bureau of 

 Entomology and Plant Quarantine, for help given me from time to 

 time.
