Hudson. — On the Xcic Zealand Cicadee. 55 



The alleged occurrence of the well-known Mole-cricket 

 {Gryllotalpa vulgaris) in various parts of New Zealand has in 

 some instances been probably due to the observation of a 

 Cicada pupa, which, when alive and partially covered with 

 Ciirth, might readily be mistaken for the larva of that insect, 

 although, of coui'se, in reality it has no manner of afi&nity 

 with it. 



In conclusion, I will give a brief summary of the leading 

 characters of the New Zealand Cicadce : — 



A. Cicnf7<B with a median band. 



1. On protlioras only. 



C. cingidata, Fabi". 



2. On thorax and abdomen, very strongly pronounced. Very vtiri- 



able — green, black, red, and yellow, with black markings. 

 C. viuta, Fabr. 



3. With median band faintly indicated both on thorax and abdo- 



men, bronzy-green, with reddish-brown markings. Constant. 

 C. tristis, n.s. 



4. Entirely green, with median band on abdomen only, and two 



minute black markings on thorax. Constant. 

 C. aprilina, n.s. 



B. Cicada without median band. 



5. Small, with no distinct markings. Constant. 



C. iolantlie, n.s. 



6. Larger, with thoracic markings faintly indicated. ? covered with 



greyish down. Constant. 

 C. cassiope, n.s.
