Phasmoidea. I quite agree with Shipley, 1904 ("The Orders 

 of Insects," Zool. Anz., Vol. 27, pp. 259-262), however, in his 

 contention that the terms applied to the orders of pterygote 

 insects should always end in "-ptera," for the sake of uniform- 

 ity. Since the term Phasmoidea does not end in "ptera," I 

 would substitute for it the designation Cheleutoptera (refer- 

 ring to the folding of the hind wings in longitudinal plaits, 

 when at rest), and would also remove the Phylliidae from the 

 "Phasmoidea," and place them in a separate order, the Phyl- 

 loptera. 



The grasshoppers differ from the remainder of the "Salta- 

 toria" in that the ovipositor is short, the cerci are greatly re- 

 duced, the sterna of the meso- and metathorax instead of being 

 separate, are closely united and interlock (or are "dove-tail- 

 ed") in a peculiar fashion, there is no plate (the laterosternite) 

 between the mesothoracic sternum and pleural region as in the 

 other forms, a single pulvillus (absent in the other forms) oc- 

 curs between the tarsal claws, the labium and other mouthparts 

 are different from those of the other forms, as is true of the 

 antennae (which are short, and have segments of a different 

 character), etc., etc. I have therefore placed the grasshoppers 

 in a different order, which I would call the Diphtheroptera 

 (or "leather-wings," referring to the nature of the tegmina). 



The crickets and katydids form the greater part of the order 

 "Orthoptera" (in the restricted sense), and compose its two 

 principal suborders. The crickets form a distinct suborder, 

 the Gonioptera (so-called from the fact that the lateral por- 

 tion of the tegmina is bent downward and forms an angle with 

 the upper portion of the tegmina) ; and the katydids form an- 

 other well-defined group, which may be called the Phytoptera 

 (from the resemblance of the wings to parts of the plants). 

 The Gryllotalpidae possibly form another suborder, the Para- 

 phytoptera, intermediate between the other two ; but this point 

 needs further investigation. The Phasmodes-like forms are 

 sufficiently different from the other katydids to form a dis- 

 tinct suborder if not a distinct order; which may be desig- 

 nated as the Protophytoptera.
