feeding on various foodstuffs made of wheat flour. Eggs to 

 the number of thirty-six contained in the ootheca; 76. 



103. Oriental Cockroach Blatta orientalis (Linn.). Fre- 

 quenter of both country and city houses, dark basements pre- 

 ferred, but occasionally going to the upper floors of steam-heated 

 buildings. Eggs to the number of sixteen contained in the 

 ootheca; 76. 



104. American Cockroach Periplanata americana (Linn.). 

 Largest of the household cockroaches, originally a native of 

 the tropics; it frequents basements; 76a. 



105. Australian Cockroach Periplanatfi australasicB (Fab.).

 floor of country dwellings, but quite rare; also found in sandy 

 fields under rubbish; 47 and 76. This species is often confused

 (Bruner) . Frequenting the underground galleries of ants, feed- 

 ing on the oily secretions of their bodies, and such substances, 

 lining the galleries. It lives as a tenant or inquiline. 



Second Section: Habitats above Ground. 

 Phytodytes. 



The species belonging to this series live above ground on 

 vegetation. With their round, rasp-like, or flattened blade- 

 like ovipositors they are enabled to place their eggs in various 

 ways. Some of the eggs are deposited in the pith of twigs or 

 in bark of trees by drilling holes (meadow, shrub, and tree 

 crickets), or the eggs are inserted between the stems and leaves 

 of grasses (meadow grasshoppers and cone-head katydids), or 

 they are inserted in slits in the edges of leaves (meadow and 

 shrub katydids), or in crevices of bark (true katydids), or they 

 are plastered to the stems or along the outside margin of leaves 

 (large- winged katydids and mantis'). The phytodytes gener- 

 ally lay their eggs on or in parts of live vegetation. They 

 are divisible into five series as follows: 



1 The mantids have inconspicuous ovipositors.
