ness without abusing it, and especially not to anticipate improperly in 

 a paper, which, as I supposed, would appear before his work appeared, 

 the terminology and nomenclature to be introduced into the latter. 

 However, owing to causes over which I had no control, no part of my 

 paper appeared till Dr. Enslin's work was already published ; and, as 

 I had feared from the first, the paper — which, unless read as a whole, 

 was bound to be almost unintelligible — could not be published as a 

 whole, and had to appear in fragments (disjecta membra) scattered 

 through several numbers (and not even consecutive numbers) of 

 Ent. Mo. Mag. (February, March, and June, 1914). Also the Index 

 on the cover of the June number made it appear that these " Help- 

 Notes "as a whole were now " concluded " ; and this has brought me 

 letters from several readers of my papers, to which I must now reply 

 by explaining that such is not the case ! I have still to tabulate as 

 best I can the <$ g of British Tenthredopsis ; and further, since I 

 commenced the " Help-Notes " in January, 1903, many things have 

 happened to make at least the earlier papers of that series more or 

 less obsolete. The classifications and terminologies introduced by 

 Konow, which I then thought it wisest to adopt with a minimum of 

 discussion, have since been reconsidered by himself and others, and no 

 longer represent (as they then did) the latest views of hymenopter- 

 ological experts. Mr. Eohwer (followed at present, though unwillingly, 

 by Dr. Enslin in his Revision of Central European Tenthredinoidea) 

 has proposed a number of reforms in the hitherto generally accepted 

 nomenclature, some of which, I believe, will have to be adopted, 

 though as to others I think he is mistaken, and shall shortly be 

 discussing the subject elsewhere, viz., in the Transactions of Ent. Soc. 

 Lond. Also, since January, 1903, I have become acquainted with 

 several forms not then known to me as British — species, sexes of 

 species, and even genera ! And, though I have alluded to these in 

 " Help-Notes " from time to time as they came to my knowledge, the 

 allusions are at present scattered, and must be brought together in 

 some way — indeed it will probably be desirable to re- write some of my 

 original synopses in order to include the forms at present omitted 

 from them. 



Evidently, then, here is material for at least two or three more 

 instalments of " Help-Notes," before I can write " concluded" to the 

 series, and lay down my pen. 



Perhaps I may here make a petition, viz., that correspondents 

 who have sent to me specimens which I have returned to them as not
