ORTHOPTERA 49 



(c) Forewings broadly oval, with broad areas traversed 

 by numerous closely parallel veins (many cock- 

 roaches are wingless). 



(d) Short tails. 



(e) Absence of ovipositor in the females: the eggs are 

 laid in big cross-ribbed egg cases, that are left in 

 crevices and in runways and other dwelling places 

 of the adult roaches. 



2. With a mantis in hand, note another distinct, and 

 rather grotesque type of structure, viz. : 



(a) A body angulate at the middle joint, cylindric 

 in front and flattened behind. 



(b) Legs correspondingly differentiated into one pair 

 for grasping in front and two pairs for standing 

 behind. 



(c) Head narrowed behind the rounded and prominent 

 eyes into a long necklike portion. 



(d) Antennae short, slenderer, threadlike. 



(e) Rapacious jaws; sharp toothed at their tips. 



(f) Prothorax very long, cylindric, bearing the legs 

 far forward. 



(g) Fore legs with extremely long and strong coxae; 

 femora and tibiae, all toothed for grasping and 

 holding prey. 



(h) Slender middle and hind legs, and 5-jointed tarsi, 

 (i) Broad fore wings, that in color and veining often 

 resemble leaves.
