 cada obferved by fir George Staunton, in the route of the 

 Britifh embafly to the court of Pekin, and noticed in his 

 work under the trivial name of the uoify cicada. "The 

 mufic emitted by a fpecies of cicada," fays that writer, 

 " v.as not of the vocal kind, but produced by the motion of 

 two flaps or lamells, which cover the abdomen, or belly 

 of the infeft. It is thefignal of invit:ition from the male of 

 that fpecies to allure the female, vs-hich latter is quite un- 

 provided with thefe organs of courtfliip.". — On this fubjecl 

 it is remarked, in the Hiftoi-y of Chinefe Infects referred to 

 above, that thefe organs of found are by no means peculiar 

 to the individual fpecies fir George defcribes ; all the males 

 in that feftion of Linnaean cicadae v/hich Fabricius calls 

 tettlgotia, are furnifhed with fuch lamell?», and emit a fjund 

 in like manner ; and the males of thofe fpecies included in 



6 



the other feclions of that genus are certainly furninied with 

 them alfo, although in fome kinds they are very fmall, and 

 in a few inftances not vifiblc to the naked eye. Thefe organs 

 will be noticed more particularly in fpeaking of the genu* 

 cicada.
