white witli dark tips; tarsi Mack. Style — Ensiform, sickle-shaped, one-half the 

 Icngtli of the cornicles. 



Hosts — Feeding in largr nmnlxTs upon the young and hiul<r fronds of tlic 

 Boston fern (Nephrolepis iwuUata). Davis rejiorts this species as feeding upon 

 Svrord ferns, and Fullaway collected specimens from Acrostichum reticulatum. 

 Neuls found it on cultivated violet at Claremont, Cal. 



Locality — House ferns at Santa Paula, Cal. Date of collection — March 18, 

 1.011. Serial number 19. 



Davis first obtained thi.s .species from greenhouses in Chicago where it had 

 no doubt been imported from other places. Since his description was published, 

 Fullaway, of the Hawaii Agricultural Experiment Station, has described what I 

 believe to be the same species from the Hawaiian Islands. It is, therefore, without 

 doubt, a native of those islands and has been imported into the larger greenhouses 

 on the Pacific Coast and from these to the various parts of the United States. It 

 is yet a rare species and a very beautiful one. Davidson has collected it in the 

 central part of the State and, as stated above, J. Neuls collected it on the Pomona 

 College Campus at Claremont, Cal.
