8. Labia curvicauda (Motschulsky). 



1863. Forficelisa curvicauda Motschulsky, Bull. Soc. Nat. Moscou, 

 XXXVI, p. 2, pi. II, fig. I. [Nura-Ellia Mountains, Ceylon.] 



1912. Labia curvicauda Rehn and Hebard, Proc Acad. Nat. Sci. 

 Phila., 1912, p. 237. [Long Key, Florida.] (First United States 

 record.] 



The species is known from the United States only from 

 the large series taken at Long Key, Florida, in the dying 

 tops of cocoanut palms, at the white bases of the petioles 

 where these were moist. 



:). Prolabia pulchella (Serville).

 U. S. Nat. Mus., XXXVIII, p. 451. [Florida; Thomasville, Georgia; 

 Texas.] 



1911. Prolabia unidcntata Burr, (in part, not of Beauvois, 1917), 

 Gen. Ins., Fasc. 122, Dermapt., p. 57. [United States.] (Generic as- 

 signment.) 



Careful comparison of all the material before us of the Unidentata 

 Group, proves conclusively the above synonymy, as has been indicated 

 by Burr. Contrary to that author's opinion, however, the species 

 found in the United States is distinct from the West Indian Prolabia 

 unidentata (Beauvois). 



In pulchella, the male pygidium is distinctive in being roughly sub- 

 quadrate, with broad distal margin subtruncate. 



^One specimen, collected by Schaum, bore no data : the other was 

 labelled "Niagara"; clearly mislabelled or an adventive specimen.
