specimens available to Schultz and Chapman, and a large number of 

 additional specimens resulting from increased collecting in recent 

 years, is considerably different from previous studies. This difference 

 is due not only to the increased amount of material, but also to a 

 reinterpretation of the published data and my employment of addi- 

 tional taxonomic characters. 



A large number of individuals and institutions aided me by pro- 

 viding specimens or laboratory space. To these I am greatly indebted, 

 for without their consideration my study could never have progressed 

 this far. To the following institutions and their personnel, responsible 

 for the assistance I received, I extend my sincere appreciation (ab- 

 breviations as indicated are used throughout the text) :
