no.1760. THE EARWIGS OF THE U.S. XATIOXALMUSEl 1/ BURR. 463 



Last dorsal segment, male and female, transyerse. 



Forceps with branches remote at base, elongate, slender in both 

 sexes, with strong teeth in the male. 



This genus is erected for the remarkable earwig from Cuba de- 

 scribed under the name of Forficula schwarzi Rehn, which is the 

 type. 



In spite of the narrow sternal plates and elongate body, it has all 

 the appearance of the Anechurinse, especially the peculiar pygidium. 



It is well characterized l>\ the tarsi, which are quite different from 

 those of any other known genus of the subfamily.

Forficula schvjarzi Rehn I L905 1 i, p. 513, fig. 9. 

 Sphingolabis schwarzi Caudell ( 1007' i, p. 170. 



Cuba. — Santiago Province; Cayamas, March I. One fem.de 

 (Schwarz, Cat. No. 8169, Rehn's type); same locality, one male, 

 May 25 (Schwarz, the original male first described by 

 Caudell). 



This elegant species was first described from a. single 

 female in poor condition; the abdomen had been broken 

 off and in repairing had been cemented on upside down. 

 The same collector later took a. male in the same locality, 

 which is described by Caudell. 



An examination of these two specimens, the only ones 

 so far known, shows that the pygidium is, in its essen- 

 tials, typical of the Anechurinse, to which subfamily 1 fig.s. tar- 

 have little hesitation in referring it. > .„<„•, x 



& SCHWARZI. 



Superficially, in color and general appearance, it must 

 resemble the little-known Anechura < l<>)i<j<it<t Bormans, likewise from 

 Cuba, but the form of the pygidium and forceps is different.
