OX A COLLECTION OF THYSANOPTERA FROM 

 PANAMA. 



By J. Douglas Hood, 

 United States Biological Survey. 



A small collection of Thysanoptera made in the Canal Zone, 

 Panama, by Mr. James Zetek of the Isthmian Canal Commission 

 during the year 1912, furnishes the basis for the present article. 

 There appear to be no published records of any thrips occurring 

 in that region. This fact, together with the finding of two species 

 new to science and the knowledge gained of the distribution of 

 the several other species, has made the collection of more than 

 passing interest. Under each species mentioned is given a summary 

 of its known geographical distribution, together with such addi- 

 tional locality records as are furnished by the specimens in all 

 collections to which I have had access. 



Franklinothrips vespiformis Crawford. 



Distribution: Managua, Nicaragua (Crawford); Florida (Back); 

 Brownsville, Texas; Miraflores, Canal Zone. 



An easily recognized species, very distinct from /Eolotlirips in 

 which it was originally described. Known previously only from 

 Nicaragua and Florida, but quite common in sweepings from grass 

 and weeds at Brownsville, Texas, and in the Canal Zone. 



Frankliniella insularis Franklin. 



Distribution: Barbados (Franklin); Guadalajara, Mexico (Craw- 

 ford); Brownsville, Texas (Russell); Monterey, Mexico; Mira- 

 flores, Canal Zone, Panama. 



Probably the most abundant thrips in Central America. The 

 specimens from Miraflores were taken in " sweepings along a stream 

 and in small clearings."
