OF WASHINGTON, VOLUME XVI, 1914 29 



Mr. Hood stated that the thrips taken by Mr. Pierce on T/n/r- 

 beria should be known as Frankliniella insularis (Franklin), and that 

 the genus Euthrips Targioni-Tozzetti, in which it had been placed, 

 is used by the best workers in the stead of Anaphothri i>* \ "/el. In 

 addition to the localities mentioned, Fraiildiniflld insularis ha- 

 been recorded in the literature from Brownsville, Texas (Russell, 

 Proc. Ent. Soc. Wash., vol. xiv, p. 128; 1912); Monterey, Mexico; 

 and Miraflores, Canal Zone, Panama (Hood, Psyche, vol. xx, p. 119, 

 1913). It has also been taken at Georgetown, British Guiana, by 

 Messrs. G. E. Bodkin and L. D. Cleare, and has been found by Mr. 

 Alex. Wetmore in the stomach of a Green Mango Humming Bird 

 (Anthracothorax viridis), taken at Utuado, Porto Rico (Biological 

 Survey, No. 105072).
