Canadian Orthoptera. 403 



neus. It is an imported species, infesting houses and ship- 

 ping. Quebec, Provancher : Montreal, common, Caulfield : 

 Toronto, Brodie. 



The other imported species is the small, reddish-brown 

 Cockroach, Ectobia germanica, Stephens, commonly known 

 in the New England States as the " Croton Bug." It 

 infests houses, and is even more troublesome than the large 

 species, taking up its quarters in wooden partitions and 

 cracks in furniture, soon becoming unpleasantly numerous. 

 Chaudiere Curve, Quebec, Fyles : Montreal, Caulfield : 

 Toronto, Brodie. 



Our native species are found under stones and beneath 

 the bark of stumps, and appear to be rare. Ectobia litho- 

 phila, Harr. Welland and westward, Brodie. Periplaneta 

 americana, Linn. Essex County, Ont., Brodie. Ischnop- 

 tera pennsylvanica, De Geer. This species is light brown, 

 has the wings much longer than the body, and is extremely 

 active. I found a specimen under the bark of an old stump, 

 June 1876, and on the Natural History Society's Field Day 

 to Abbotsford, on June 4th, 1885, I took three specimens, 

 also under bark of a stump. Toronto, not common, Brodie. 

 Temnopteryx marginata is a smaller insect, with much 

 shorter wings. I found two specimens under bark of a 

 fallen tree, on Montreal Mountain, June 1876. It has not 

 been taken elsewhere in Canada, so far as known to me. 



The Earwigs. Forficulid^e may be distinguished from 

 all other orthoptera, by their narrow, flattened body, short 

 wing-covers, and by the extremity of the abdomen being- 

 provided with a forceps, which, in some species, equals the 

 body in length. During the day earwigs generally conceal 

 themselves in holes and crevices, flying actively at night. 

 A few of the smaller species fly during the day. They feed 

 on vegetable matter, and in Europe, where they are 

 numerous, often do much damage by eating the blossoms of 

 Carnations, Dahlias, &c. In this country they are gener- 

 ally rare insects, only one species being recorded from 

 Canada, the Labia minor of Linnaeus, common to both 

 Europe and America. Cap Bouge and Portneuf, 3 speci- 

 mens, Provancher : Ottawa, Harrington.
