TWO NEW THYSANOPTERA FROM PORTO RICO 



By J. DOUGLAS HOOD 



The thrips of Porto Rico are almost entirely unknown. The only 

 record of any named species occurring on the island seems to be in a 

 footnote of a recent paper by H. M. Russell,^ in which he states that 

 Mesothrips ficoTum Marchal " causes injury to various species of Ficus 

 in Key West, Cuba, and Porto Rico." Below, two additional species, 

 both new, are described from material generously referred to me by Mr. 

 Russell. They were collected by Mr. Thomas H. Jones, of the Esta- 

 cion Experimental de la Asociacion de Productores de Azucar, Rio 

 Piedras, Porto Rico, and are of interest in increasing our scant knowledge 

 of the Neotropical Thysanoptera.
