ORTHOPTERA OF NOVA SCOTIA—PIERS. 209 
under stones and the bark of stumps; (2) the Gryllide or 
crickets, two species reported; (3) the Locustide or grass- 
hoppers, two species reported ; (4) the Acridide or locusts, eight 
species. Of the remaining North American families—the 
Forticulidee or earwigs, the Mantidee or praying mantes, and 
the Phasmide or walking-sticks—I have so far met no specimens. 
Tam under obligations to Dr. Samuel H. Seudder, of Cam- 
bridge, Massachusetts, the best authority upon North American 
Orthoptera, and also to William Beutenmiiller, Esq., Curator of 
the Department of Entomology, American Museum of Natural 
History, New York, for examining specimens and thus checking 
my own determinations. The nomenclature of my paper follows 
in the main that of Mr. Beutenmiiller’s “ Descriptive Catalogue 
of the Orthoptera found within fifty miles of New York City” 
(Bulletin American Museum of Natural History, vol. vi., 1894, 
pp. 253-316.) 
BLATTIDA. 
Phyllodromia germanica (Linnzeus). 
Croton Bug; German Cockroach. 
This species, which is a native of Europe, made its appear- 
ance in New York at the time the Croton aqueduct was built. 
It is very abundant in some houses in Halifax, and is locally 
known by the name “ Yankee Settler.” It is a small species, 
about 16 mm. in length, and is of a yellowish brown colour, with 
two dark-brown longitudiual stripes on the thorax. Warm 
places, such as the vicinity of fire-places and hot-water pipes, 
are most attractive to it; and it is said to be particularly 
destructive in buildings heated by steam. It is less hkely to be 
found in filthy surroundings than the oriental cockroach. The 
great rapidity with which it breeds, and its small size, which 
permits it easily to hide itself in cracks, make the species one of 
the worst insect pests in cities. Dr. Riley was of the opinion 
that Persian insect powder was the best means of stopping the 
inroads of this roach. The species is less strictly nocturnal 
than S. orientalis.
