In this series the proximity of Chrysochraon, Stenobothrus aDd some 

 other geuera to Tryxalis is an improvement on the arrangement adopted 

 in this Catalogue. 



The Phasma-tribe come between the Mantodea and the Acridids, 

 and I believe that the Blattaria should be placed next the Gryllidae, 

 though there is no link between them, and the Forficulaiia are still more 

 widely separated from the Blattaria, and especially by the peculiar 

 abdominal appendage which is adapted to manipulate the wings. There 

 is another missing link between the Forficulaiia and the Thrips-tribe, 

 and a greater space between the Dermaplera and the Tbysanura, to 

 which the Ceuthophilidse have an outward resemblance. 



The tribes represented by Libellula, Ephemera and Tonnes have been 

 included in the Dermaptera by some authors, and other authors have 

 supposed that the Dermaptera are connected with the Neuroptera by the 

 genera Mantis and Mantispa.
