 ocelli none.

ORDER XI. Orthoptera. 



Hexapod insects, with four wings, the upper coriaceous elytra, 

 the lower membranous and folded in their length radiately like a 

 fan. Mouth constructed for manducation, with strong mandibles ; 

 maxillae furnished with galea cylindrical, vesicular (internal palp). 

 Metamorphosis incomplete. 



Straight-winged. OLIVIER first separated these insects under the 

 name of Orthoptera from the order of the Hemiptera of LINN^EUS^ 

 and characterised this new order by the mode in which the under- 

 wings are folded and by the presence of a galea on the lower jaws. 

 In the oral parts they differ altogether from the liertiiptera. But if 

 we stand, not upon the name of the order, but upon the distinction
