Among the other Cercopidce in the portion of the collection sent 

 to mo are four varieties of the fine Cercopis {Sphenorhina) circulata, 

 Guer. ; in two of these the darker colour is replaced by light testa- 

 ceous, in one the colour is a sort of orange and the markings are 

 irregular, and the fourth is almost entirely black ; there is also a 

 variety of Tomaspls {Monecpliora) inca with the tegmina not banded,
