246 ORTHOPTERA OF NOVA SCOTIA. — PIERS. 



with mouth in front; wing-covers leathery, very short, and 

 without veins; tarsi five-jointed; the abdomen endii\g in 

 a horny, forceps-like appendage. No species of the Forfi- 

 culidce are known to occur in Nova Scotia, although Labia 

 minor (Linnaeus), the Little Earwig, coloured black and yel- 

 lowish-brown, with last abdominal segment and forceps red- 

 dish-brown, and about 5 mm. long, may yet be detected here, 

 as it is the most northern species and occurs in the United 

 States and Canada east of the Rocky Mountains, as far 

 north as Maine, New Hampshire, Vermont, Quebec and 

 Ottawa. It might easily have been overlooked by our 

 collectors. Joseph Perrin of McNab's Island, Halifax Har- 

 bour, informs me that he was familiar with it in England, 

 and thinks he saw several in the spring some years ago about 

 his garden on that island; but he preserved no specimens and 

 consequently it is merely a matter of opinion. According 

 to his recollection the insects he saw were about half an inch 

 in total length, which would be too long for the total maximum 

 length (8 mm.) of this species. C. B. Gooderham, of Truro, 

 has never seen or heard of the species in the western part 

 of Nova Scotia. 



No species of the family Mantidce (Praying Mantids) 

 occur even as far north as the New England States; and of 

 the Phasmidce (Walking-sticks), Diapheromera femorata (Say) 

 has been taken commonly in most of the New England 

 States, but not in Maine, and therefore cannot be expected 

 to extend into Nova Scotia. 



Family BLATTiDiB (Cockroaches). 



Head almost concealed beneath pronotum; body short, 

 broad, oval and flattened; pronotum shield-shaped; wing- 

 covers usually parchment-like or leathery and thickly veined; 

 abdomen ending in cerci, but these not distinctly forceps- 

 like; tarsi five-jointed.* Only introduced species are known 

 to occur in Nova Scotia.
