A LIST OF THE IIEMIPTERA OF ORIENTAL CHINA 

 by f G.-1V. Kirkaldy 



PART II 



The first part appeared in thèse « Annales » for 1909 (vol. LUI, 

 177-83), and dealt with the Cicadidse and Cercopidse. The présent 

 part concludes the Cercopidae, and enumerates the Cimicoideae. 



In the first part, an unfortunate printers' error occarred. On 

 p. 183, the paragraph commencing « Distant has... » to the end, 

 and also « Philagra Stâl. » should hâve gone on p. 182, immediately 

 before « n° 43, P. tongoidcs ». 



To the Cercopidse add : 



44. Machœrota punctatonervosa Signoret. — « China. » 



Distant (1907, Faun. Ind. Rb., IV, 79) says that « this subfamily 

 [Machserotinae] distinctly links the Membracidae with the Cercopidse. 

 Some writers reserve the position of thèse families; but in either 

 case the Machœrotinœ are placed next to the Membracidae, with 

 which they are often confused by those who hâve not specially 

 studied the Homoptera ». 



I venture to say (1) that the Machaerotinae should not be placed 

 next to the Membracidae, but on the further side from them of the 

 whole Tetigoniid séries, and that (2) any link between them is one 

 of superficial resemblance, and not of homological structure. 



The structure of the face at once séparâtes the Membracidae from 

 any other group of the Cicadoidese, but the structure of the antennse 

 and legs groups together the Membracidae and Tetigoniidae apart 

 from the Cercopidae; while the more generalized Membracid 

 nymphs are clearly modified Tetigoniids, not Cercopids. 



It is true that, typically, Machaerotinae and Membracidae both hâve 

 notai processes lying more or less along the back, but there is a 

 profound différence. In Machœrotinae this is Mesonotal, while in 

 Membracidae it is Pronotal, and thus the ornamentation is not at 

 ail of a homologous nature in the two groups. One might as well 

 say that Fulgora, Philagra and Namsangia ought to be linked 

 together because they hâve elongate cephalic processes ! 



The accompanying « tree » of the Auchenorrhynchi seems to me 

 to be well founded according to our présent knowledge. It will be 

 évident that there is not, as Mr Distant prétends, any sort of
