NEW THYSANOPTERA FROM FLORIDA AND 

 LOUISIANA. 



By J. Douglas Hood and C. B. Williams 



Washington, D. C. ; Merton, Surrey, England. 



The Thysanoptera described below were with the exception of 

 one species collected in November and December, 1914, by Mr. C. B. 

 Williams during a short trip in the Southern States to some of the 

 field stations of the Bureau of Entomology, United States Depart- 

 ment of Agriculture. Only a very little time could be spared for 

 collecting, which was done in each place almost entirely within a 

 short distance from the field stations, that at New Orleans being in 

 connection with the Sugar Planters' Station in Audubon Park. The 

 specimens of Symphyothrips pnnctatus were in the collection of the 

 field station at Orlando. In all, eleven species and three genera are 

 described as new. 



The holotypes, allotypes, and a portion of the paratypes have been 

 placed in the collection of Mr. Hood; a set of paratypes has been de- 

 posited in that of the American Museum of Natural History; and 

 the balance of the material has been retained by Mr. Williams.
