 Dear Sir, — I have received the list of the Hymenoptera of 

 New Zealand by P. Cameron, published in your Transactions, 

 vol. xxxv., pp. 290-299. This list contains such a large number 

 of errors that I think it necessary to send you a revision of the 

 New Zealand species of Formicida?, as now known. Of the 

 species named in the list Aphcenogaster antarctiens, Smith = Mo- 

 nomorium antarcticum, White, Smith named it Atta antarctica, 

 while Cameron made an Aphamogaster of this false Atta — the 

 Aphwnogaster being more erroneous than the Atta. In the fol- 

 lowing paper I have given the necessary synonymy. 



Mr. Cameron has forgotten to include in his list many new 

 species discovered since 1892, and has added species that do not 

 exist. He gives no Lasius in New Zealand, and Formica zea- 

 landia = Melophorus advena, Smith. Emery suggested that my 

 Strumigenys antarctica may be a synonym of Orectognathus per- 

 plexus, Smith, because he thinks Smith has miscounted the 

 number of joints of the antennae ; but, as it is only a suspicion, 

 it must wait for more material. 



I have no doubt that the North Island will furnish further 

 new species after careful search, especially in vegetable mould 

 and the hollows of trees. — Truly yours, 



Prof. Dr. Forel.
