To some of the names in this classification certain objections are 

 evident. The use of the family names Perlidae, Psocidae, Termitidae, 

 Embiidae, Ephemeridae, as ordinal names is to be deprecated. 



On the other hand a common termination such as "-ptera", which 

 already exists in many of the larger groups, should be extended if pos- 

 sible throughout the entire Class. I therefore venture to put forward 

 certain new names, all of which have a common ending and therefore 

 would simplify the terminology of the Orders which are now so nume- 

 rous. I propose 1) that we confine the word Aptera to the Thysanura, 

 2) that we call the CoUembola Apontoptera, from the Greek aitovx — 

 (absent); 3) that we call Mallophaga Llpoptera, from the Greek XiTt — 

 (yle/TTw); 4) that we call the Anoplura (Pediculidae) EUipoptera, from 

 the Greek iXkirt — {sXlei^rtco), 5) that we resume the term Aphaniptera 

 for the Siphonaptera; 6) that we retain the name Plecoptera, used 

 by Brauer, for the family Perlidae; 7) that we call the Psocidae 

 Psocoptera; 8) that we call the Termitidae Isoptera; 9) that we call 

 the Embiidae Embioptera ; 10) that we call the Ephemeridae Epheme- 

 roptera; 1 1) that we adopt the name Paraneuroptera for the Odonata; 

 12) and that we retain Packard's name Mecaptera tor the Panorpatae. 



These new names obviate the difficulty of calling what are now 

 recognized as Orders by family names, and, if adopted, would give an 

 uniform termination to all the twenty-two Orders which are now re- 

 cognized in the Class Insecta. 



In drawing up these new names I have taken advantage of the 

 advice of Dr. D. Sharp and Mr. F. J. H. Jenkinson, University 

 Librarian here, so that I trust they will meet the requirements of 

 Science without offending classical scholarship. 



Accepting these new names the names of the Orders of the class 

 Insecta will be as follows: 



1 Sharp, 1. c, did not admit the Panorpatae to be certainly distinct from 

 Neuroptera. I have however given them a distinct place in the list of Orders 

 hereafter set out, because they are considered distinct by some taxonomists and are 

 already provided with a suitable name.
