188 THE ENTOMOLOGIST. 



thoscelis cinereus seemed to be particularly common and of large 

 size in the New Forest at the end of the summer, and Mr. Sopp 

 took it at Farnham (SurrejO aiid at Aldershot. By the discovery 

 this season of the wart-biter {Decticus verrucivorus) a few miles 

 from Dover, Mr. Burr has been able to place this handsome 

 species in a much more secure position on our list. The wart- 

 biter is one of the largest and most powerful of our Orthoptera ; 

 but authentic British records are few in number. 



Gryllodea. — At last the little wood cricket {Nemobius sylves- 

 tris) has come to light outside the boundaries of the New Forest. 

 Mr. F. Morey, of Newport (Isle of Wight), tells me that it has 

 been found by himself in Parkhurst Forest, and by Mr. H. F. 

 Poole in Bordwood, also in the island. It should be added, 

 however, that Piev. F. C. K. Jourdain once told me that it had 

 been taken at Willington, in Derbyshire, by Mr. G. Pullen. 



BIBLIOGRAPHICAL AND NOMENCLATOEIAL NOTES 

 ON THE HEMIPTERA— No. 9. 



By G. W. Kirkaldy. 



In my earlier papers in the ' Entomologist ' I invariably 

 employed the term " Rhynchota " as the scientific appellation of 

 my favourite order. As I have in later years substituted for 

 this " Hemiptera," and as I fell into error in No. 2 of these notes, 

 and as a number of entomologists still use "Rhynchota," it 

 will, I think, be well to see what is the correct term to employ, 

 and why. 



The Hemiptera were one of the original orders (1758) of 

 Linnfeus, and embraced eight genera, viz. : Cicada, Notonecta, 

 Nepa, Cimex, Apliis, Clicnnes, Coccus, and Thrips ; thus, except 

 for Thrips, a form of doubtful affinity, corresponding exactly to 

 modern conceptions of Hemiptera.* 



In 1775 Fabricius altered all the ordinal names of Linnaeus, 

 Hemiptera becoming Ryngota. The genera were increased to 

 seventeen, but except that Pulex appears now in this order, the 

 latter is coterminous with the Linnean order 



In 1783 Retzius, professing to make a summary of De Geer's 

 " Memoires," split the order into three, as follows : — 



Class 5. Siphonata {Thrips, Aphis, Chermes, and Cicada). 



Class 6. Dermaptera {Cimex and Nepa). 



Class 10. Proboscidea {Coccus). 



In 1802 Latreille founded Homoptera and Heteroptera. 



In advocating the retention of "Hemiptera," it is not 



■'• Pe^ZictiZtts, placed by Linnabus in "Aptera," is referred by some modern 

 authors to Hemiptera, but this does not affect the argument.
