El Taste; he also recorded a series of 34 specimens of H. aurata from 

 the former locality. We have examined one male and four females 

 from San Jose del Cabo and one male from El Taste, all Eisen Collec- 

 tion, also one female from Todos Santos, W. M. Mann. These seem 

 to be conspecific, in spite of the differences between the sexes as indi- 

 cated in the above description. Townsend made no mention of the 

 sex of any of his specimens of either H. eiseni or what he took to be 

 H. aurata; apparently he interpreted the males of the series as H. 

 aurata and the females as the new species that he described as H. 

 eiseni.
