In 1896 Johnson recorded a Signiphora nigrita Howard MS. as a 

 parasite of Aspidiotus foriesi Johnson; this species is a nomen nudum 

 and is described beyond. Two years later, De Dalla Torre gave the 

 following catalogue of the group:

Ashmead (1900) then made an important contribution to the 

 knowledge of the group, describing 12 new forms and giving the fol- 

 lowing table of the species. Fourteen species were Hsted. I quote 

 the table herewith, especially in order to allow a more ready and con- 

 venient comparison of it with my own, given later.
