NO. 1590. ON SOME NEW WEST INDIAN THRIPS— FRANKLIN. 729 



slender, knobbed, very conspicuous, and toward the base of alidomen 

 shorter and less prominent. There are two of these knol)bed spines 

 on each side of segments two to nine, inehisive; on the posterior seg- 

 ments these spines are rather close together, but on tlie anterior ones 

 rather widely separated, the inner ones being placed more than half 

 way from the extreme sides to the middle line; on each side of the 

 middle line of dorsal segments two to six, inclusive, is placed a single, 

 rather short, conspicuous, acute, double-curved spine. The surface 

 of dorsal segments two to seven, inclusive, is reticulated. 



Described from one specimen (the type) deposited in the collection 

 of the Massachusetts Agricultural College. 



Male luiknown. 



Specimen captured at Glendor, St. Michael, on leaf of Hme,

This species is, in some ways, rather abnormal for Ci-yptothrip^^^ 

 and possibly a new genus should be erected for it, but I think it better 

 for the present at least to leave it as a member of that genus. 



Herr H. Karny, in his paper Die Orthopterenfauna des Kiisten- 

 gebietes von Osterreich-Ungarn," has incorrectly used the genus 

 luime PlnjHapus. This name can not be applied to species of Thy- 

 sanoptera, as it was first used by Leach for a genus of the Neurop- 

 tera as Doctor Hinds has made clear. He has further erred in using 

 the name atei' for E. culgatissimus (Haliday), as ater was used by 

 Degeer not as a specific name but as a part of a description.
