that some of their species have the upper wings resembling leaves, 

 hence " walking leaves." In those Phasraidae devoid of wings, 

 the resemblance is to a twig or stick, "walking sticks." Although 

 very often sluggish in their movements, some are capable of 

 taking short leaps. 



The Mantidae are very voracious animal feeders: the Phas- 

 midie live entirely on vegetable matter ; they are amongst the 

 longest of insects Bacteria sarmentosa is ten inches in length.

These are voracious vegetable feeders, some of the species oc- 

 curring in vast numbers at uncertain intervals. 



In Gryllidas and Locustidse the antennae are long and setaceous, 

 with sometimes as many as 140 joints ; in Acridiidas they are 

 short and stout, rarely clavate. The ovipositor in the two former 

 families is often very large ; in Acridiidae there is no ovipositor. 

 Hemimerus is an aberrant form allied to Gryllotalpa according 

 to Walker, but for De Saussure forming a distinct order (Diplo- 

 glossata).
