OF WASHINGTON, VOLUME XV, 1913. 43 



In combating these species the Sanitary Department on the 

 Zone will have a new problem and it will probably be necessary 

 to fish up or otherwise destroy these large floating islands of 

 Pistia. 



Under the heading of short notes Mr. Schwarz exhibited speci- 

 mens of the Curculionid Anthonomus irroratus Dietz and berries 

 of Eugenia buxifolia collected by him on the island of Key West, 

 Florida during the month of April. These berries resemble good- 

 sized peas and the Anthonomus was bred in some number from 

 such berries which are slightly deformed. Upon further investi- 

 gation it was found that the author of these deformations is a 

 Cecidomyid. It appears that the Anthonomus larva destroys in 

 some way the Cecidomyidous larvae. Mr. Schwarz remarked that 

 this is not the first instance known where species of Anthonomus 

 are reported as being inquilinous in Cecidomyidous galls as in- 

 stanced by A. sycophanta Walsh, and A. aeneolus Dietz. Finally 

 Mr. Schwarz stated that A. irroratus is manifestly synonymous 

 with A. costulatus Suffrian, described from Cuba and that the 

 latter specific name has priority.
