The arraiigeuient proposed by Osteii Sackeii in 1896 was as follows

The Cyrtid.e are the same as Brauer's Ackooerid^. 



The arrangement I have adopted in this work is very nearly the same 

 as Osten Sacken's, l)ut is somewhat modified as follows :

This volnme deals with the Ekemoch^ta, TiiOMOPTEiiA, Dermatina, 

 and Energopoda. 



I am indebted to my namesake, Dr A. W. Verrall of Trinity College, 

 Cambridge, for the formation of the words Dermatina (^e/o/>caT(i/o? = the 

 leathery one) and Microphona (fxiKpo^ 0oVo? = mnrderer of little things). 

 I use the word Microphona as being; in accord with the other names of 

 the superfamilies in referring to the perfect insects, while the term 

 Orthogenya of Brauer was derived from the embryonic characters, and 

 also was imposed as of equal rank with the Platygenya. 



My arrangement is identical with that of Aldrich in his Catalogue of
