allied to the Katydid which have very broad, thick fore 
wings, some oval in shape like orange or lemon leaves, 
others with jagged outlines, somewhat as in the holly leaf. 
Others are of the color of a dead leaf. Such is the Cyrto - 
phyllus pterspicillatus , which bears a close resemblance to a 
withered leaf. There is in Brazil a grasshopper of this fam¬ 
ily, which represents the East Indian Megalodon figured by 
Wallace on page 580 of “The Malay Archipelago.” 
There are some insects which resemble anything but them-
