Forficula oceanica Blanch., Voy. Pole Sud, Orth., pi. 1, fig. 4

This belongs to a yet uncharacterized genus, and is not morio as 

 suggested by Erichson. 

 Forficula Orsinii.

 (1864). Brazil. 



The figure given by Percheron differs from the type of my bipunc- 

 tata only in having the hind border of the prothorax more rounded, 

 and is very probably an error of the engraver. 



The specimen in the Harris Collection (presumably from Massa- 

 chusetts, but, if so, very probably imported) is marked in his manu- 

 script catalogue, "May 20, 1827. From Z. Cook, Esq." 

 Forficula plagiata. 



Forficula plagiata Fairm., Arch. Ent., II, 257, pi. 9, fig. 3 (1858). 



W. Africa. 



Judging from a transcript of the description and figure kindly 

 made for me by Dr. LeConte, this seems to be a true Forficula.
