328 Mr. G. W. Kirkaldy's Memoir on the 



volumes on the "Voyage of the Astrolabe." The exami- 

 nation of large series of Rhynchota from the multitude of 

 islands comprising the Bismarck, Solomon, New Hebrides, 

 and Loyalty Archipelagoes would be exceedingly interest- 

 ing from a distributional point of view. Our principal 

 knowledge of these faunas is derived from the works of 

 Montrouzier (or Montrousier as he also terms himself), a 

 French priest, who resided in New Caledonia and the 

 surrounding islands for many years. Dr. Willey has col- 

 lected some seventy-six species, falling into sixty-five genera. 

 Of these I have described as new five genera, one sub- 

 genus, twenty species and one variety, but the principal 

 interest of his labours lies in the large proportion of 

 immature forms, the consideration of which is reserved 

 for a future paper. 



My thanks are due to Mr. W. L. Distant, for kindly 

 assistance in the determination of several species, and for 

 help with the proofs in my absence from England ; and 

 to Dr. D. Sharp for allowing me the opportunity of 

 examining so interesting a collection.

Dr. Willey has collected fourteen specimens, which I 

 have ventured to divide into two species — though somewhat 

 doubtingly — neither of which can I refer to Cicada lifuana, 

 Montrouzier, though one of them is certainly the Ucana 

 lifuana as identified by Distant. 



1. Ueana lifuana, Montr.

Montrouzier says, " Veines de la premiere moitie des 

 elytres vert-bleu. Elytres irisees,". . . . which does not 

 in the least apply to any of the specimens before me. 

 Montrouzier records it from Lifu.
