The Phasmid^e or spectres are represented in Canada by 

 only one species, the well known Walking-stick insect, 

 Diapheromera femorata Say, but in tropical countries are 

 numerous and assume strange forms, resembling leaves, 

 thorny branches, &c. Our species is entirely wingless, and 

 looks very much like a small twig. The body is long and 

 cylindrical, and the antennas and legs are very long and 

 slender. It lives altogether on trees, being generally found 

 on oak and basswood. According to Packard, the egg-sac 

 is flattened elliptical, with a lid in front which can be 

 pushed open by the embryo when about to hatch, and is 

 deposited in the autumn,

The Cockroaches. Blatari^e are flattened ovate insects, 

 generally of a dingy brown color, and have an oily and dis- 

 agreeable smell. The egg capsules are dropped at random, 

 the females not depositing or concealing them in any par- 

 ticular place or manner. Cockroaches are nocturnal insects, 

 hiding during the day in holes and crevices. They are 

 omnivorous creatures, feeding on almost any substance, 

 animal or vegetable. 



We have on our lists five genera with seven species. Two 

 of these are European, but have been carried by commerce 

 to various parts of the world. The large, black species, 

 common in houses, and familiar to housewives under the 

 name of " Black Beetle," is the Stylophyga orientalis, Lin-
