The description given of this species is so inadequate 

 that its position among the genera of AJeijrodidae cannot 

 be positively stated. For this reason we ha ve left it in the 

 genus in which it was originally described. jts habitat is 

 given as Chile.

AVe know this species only from the original des- 

 cription. It was collected at Iguagse and Campiñas, State 

 of Sao Paulo, Brazil, on cabbage and collards. The describ- 

 er states that it is found on the underside of the leaves 

 and sometimos scattered on the upper surfaces.
