Mr. Jackson's diagram on p. 177 cannot be adopted. The Sternor- 

 rhyncha must have branched off from the main Homopterous stem before 

 the latter was differentiated into superfainilics, while the association of the

Cercopidaj and " Fiilgoridjf " as " twin twigs " of a branch ahnost equal to 

 the Meml)racid3e or " jassidne," is positively ridiculous. 



The following rejjrcsents more accurately the course of lloniuptcrous 

 evolution : The Kulgoroidea are much more distinct from the rest of the 

 Au( henorrhyncha than these are among themselves ; the Cercopid.-e, 

 \Icinl)racid;u and " Jassidnj " are all very closely allied, the Membracidaj 

 being sim|)ly highly specialized *' Jassida*." 



I have not sufficiently studied the Stcrnorrhyncha as yet, but I think 

 they form only one superfamily, which may be termed " .\phoidea."
