Names in italics are synonyms of the one in Roman above. 

 There are many other synonymous names in the Hst but evidence 

 at hand is not sufficient to locate them. The names that have been 

 proposed for our species are brought together as a basis for future 

 work. Many of the types of the older students of the family are 

 not in existence at the present time, and it is likely that later stu- 

 dents have sometimes redescribed their species under other names ; 

 so it is no small task to solve present problems in a satisfactory 

 way. 



There are a few names in older works given to species with 

 habitat unknown ; some of these names may have been given to 

 specimens from this region. Such names, and .a few others ex- 

 cluded for other reasons, are not given in the list which follows.
