new Proutta which would perhaps occui" in North Wales 

 might be called PontrliydJendiyaediiiynachlocJiJaiirieUa from 

 its original locality ; it is not right to take such a word as 

 Epping and call a species epiyhujeUa, when it is almost certain 

 that a little reseaich would have found out the Latin name 

 of that Forest, and therefrom some name appropriate to that 

 locality could have been suggested. It is all very well to say 

 that it would take up too much time ; my answer to that is, that 

 scientific work should take up sui3icient time to be thorough ; 

 the next careless nomenclator may be ignorant that there 

 are such Latin words sm " awjlicus," ''hritanvicus,^' etc., and 

 may call a new species " e^iglandicus" or ^' ivalesicus " ; this 

 again would be a case of the ignorant attempting to 

 override the educated. Quite recently a Sciara from the 

 North was named " sej/temtrioncdis," bvit are we to be 

 prevented from amending this to the Latin word " septentri- 

 onalis " 1 This error is a curious one, because purists might 

 say that it was the Latin word which was mis-spelt, as its 

 derivation comes from " septem " derived from the seven stars 

 of the Gi'eat Bear, but yet ^' sej tenirioncdis" is the Latin acknow- 

 ledged spelling, and as such shoixld be used in any binomial 

 nomenclature. In my own study of the Diptera, Macquart did 

 an enormous amount of work in Exotic species and founded 

 numerous now geueia, but his knowledge of Greek was un- 

 fortunately weak, and although he always endeavoured to 

 form good names for his new genera he often failed, because 

 for instance he was not aware of the contracted Greek sign 

 for st, but mistook it for s, and consequently when he described 

 a narrow-bodied genus he called it Sejiogaster when he meant 

 Stenogasier, and this error he repeated in numerous cases. 

 I strongly object to being compelled to perpetuate such an 

 ignorant orthographical error and I decline to do so. Such 

 minor corrections as the doubling the r in Pachyo'hina or the 

 adding the aspirate in Yponomeuta are now becoming almost 

 universally accepted. 



I always come to the conclusion that not a single one of the 

 advocates of the absolute inviolability of a name as first 

 published has ever learned or even seen the rules upon which 

 binomial nomenclature was founded, and which, if the binomial
