OUTIKJPTEHA OF NOVA SCOTI A . — 1>I EHS. 251 



Its large size makes it easier to exterminate than the 

 (lerman Cockroach, as it cannot hide in narrow crevices. 

 The remedies noted under that insect, may also be used 

 a.sjainst this species; but simpler ones are likewise employed. 

 A deep jar. partially filled with stale beer or ale, with a 

 number of sticks placed against it and bent over so as to 

 project into the interior for a few inches, may be used as 

 an effective trap. The roaches climb up the sloping sticks 

 to get the beer, and then slip off into the jar. Another 

 household remedy is a saucer containing a dry mixture of 

 l)laster-of-paris with three or four parts of flour, and another 

 l)late containing water, placed near, with bridges to give 

 easy access, and one or two pieces of wood floating on the 

 water and touching the margin. The insects eat the dry 

 mixture, then go to the water and drink, whereupon the 

 plaster sets within them and causes death. Our bakers 

 say they largely employ powdered borax for keeping them 

 in check, the borax being sprinkled about infested places. 

 As they detest and avoid light, the introduction and con- 

 tinual burning of electric lights in our city bakeries has done 

 much to rid them of the pests. Infested places should always 

 be kept clean, dry, and light. '^

*PeripUineta americana (Linnaeus), the American Cockroach, a large species which is 

 a native of tropical America but has become cosmopolitan, is common along the seaboard of 

 New England, especially in city buildings and warehouses, and quite likely will be found intro- 

 duced by shipping into some of our waterside storehouses. The length of body is 27 mm. in 

 male, and .30 mm. in female, and the wing-covers in both sexes are large, extending 10-12 mm. 

 beyond the end of abdomen. The general colour is reddish brown, the pronotum margined 

 with yellow. It belongs to the subfamily BlattincB. It is probably the large cockroach 

 which is said to be sometimes brought to Halifax with cargoes of sugar from the West Indies, 

 and may have insinuated it.self into some of the warehouses of our sugar refineries. Other 

 southern species are liable to be casually introduced with bunches of bananas'
