ON A COLLECTION OF THYSANOPTERA FROM 

 PORTO RICO 



By J. DOUGLAS HOOD 



The late Dr. C. W. Hooker, while Entomologist of the Porto Rico 

 Agricultural Experiment Station, made a small collection of the Thyscin- 

 optera from the region immediately about Mayaguez, Porto Rico. This 

 collection was kindly referred to me for determination by his brother, Dr. 

 W. A. Hooker, and in it I find six additions to the known Thysanop- 

 terous fauna of the island, recorded below. 



The species previously known from the island are Gynaikpthrips uzeli 

 Zimmermann (= Phlceothrips ficorum Maichal = Liothrips bal^eri D. L. 

 Crawford) which was recorded by Russell in 1912,^ and Heterothrips 

 sericatus Hood and Podothrips semiflavus Hood, described as new in 

 1913.^ 



Frankliniella insularis (Franklin). 



This is an abundant thrips in southernmost Texas, in all of Central 

 America, in at least the northern portions of South America, emd on 

 many, if not all, of the islands of the Caribbean Sea. The Porto Rican 

 specimens bear the following data : 



Mayaguez, Porto Rico. Feb. 19, 20, 21, and 23, 1912, C. W. Hooker, in 



blossoms of Agali grandiflora, No. 1625. 

 Mayaguez, Porto Rico, March 4 and 6, 1912, C. W. Hooker, in blossoms of 



orange.
