ance could be placed upon the references in literature to tlie older 

 species. Therefore, I have omitted all but original references 

 in the s^'nonymv. Distribution as given in this paper is only for 

 specimens I have examined. 



Among the male specimens I recognize 20 species, and among 

 the female specimens also 20. Unfortunately, in only five species 

 could males and females be definitely associated. Therefore, it 

 Mas necessary to give separate names to the unassociatcd males 

 and females representing undescribed species. I regret having to 

 do this, for eventuall}- some of the new names will have to go 

 into synonymy; but it may be many years before the sexes are 

 associated, and meanwhile we shall need names for the females as 

 well as the males. Some temporary double naming is unavoidable. 



Thirty-one species are described as new, 2 from both sexes, 14 

 from males only, and 15 from females. 



Two old names are placed in synonymy.
