ORTHOPTERA OF NOVA SCOTIA PIERS. 209 



under stones and the bark of stumps ; (2) the Gryllidse or 

 crickets, two species reported ; (3) the Locustidse or grass- 

 hoppers, two species reported ; (4) the Acrididoe or locusts, eight 

 species. Of the remaining North American families the 

 Forticulidse or earwigs, the ManticUe or praying mantes, and 

 the Phasmidse or walking-sticks I have so far met no specimens. 

 I am under obligations to Dr. Samuel H. Scudder, 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.) 



BLATTID^:. 



Phyllodromia germanica (Linn?eus). 



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-brow r n 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 likely 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.
