ON A COLLECTION OF THYSANOPTEROUS INSECTS 

 FEOM BARBADOS AND ST. VINCENT ISLANDS. 



By Hekky James Franklin, 

 Of the Massachusetts Agricultural College, Amherst. 



Most of the specimens on which this paper is based were collected 

 in different parts of Barbados Island during the summer of IDOo by 

 Mr. C. C. Gowdey, a student in the Massachusetts Agricultural Col- 

 lege. The facts concerning localities, food, plants, dates of capture, 

 etc., Avere also supplied by Mr. (lowdey. 



Of the eleven districts in the island, three, namely, St. Michael, 

 St. Thomas, and St. Peters are represented, there l)eing in all 310 

 specimens from Barbados, representing 9 species of which 4 appear 

 to be new" to science. Thirty-four specimens of Heliothnps are from 

 the island of St. Vincent, having been collected there in March, 1905, 

 by Mr. H. A. Ballon, Government Entomologist, British West Indies. 

 As the Thysanoptera in this part of the world have received little 

 attention the collection is interesting, not only on account of the new 

 forms which it contains but also because of the added knowledge 

 which it furnishes concerning the distribution of those already 

 known. Two of the species more commonly found here are most 

 closely allied with very well-known and common European forms. 

 It may also be mentioned that Heliothrips hdemorrhoidalis^ so 

 abundant in a large portion of the world, is represented by numer- 

 ous specimens, and three species, so far as known, restricted to the 

 Western Hemisphere, are also present. 



Family .EOLOTHRIPID.E. 



Of this family there is but a single immature specimen which I 

 have been unable to determine Avith certainty.
