1 wish to call attention here to the subgenera of Julus. I do not 

 believe that Latzel's subgenera based on the characters of the ocelli 

 ought to be adopted, because this character is subject to considerable 

 variation. It will probably be best to retain those established by 

 Berlese in his "Jididi del Museo <li Firenze," except that the follow- 

 ing changes must be made: Arcliinhui must give way to a submenus 

 ,/uhin, because this division contains the type ufJulits. The following 

 orthography should be used: Pachyiiihis, Opliyinlns, Brachyiulus 

 (Brachyulus), and Typhloiulus, in place of that used in the above 

 pamphlet. 



9. NEMASOMA. 



1847. Nem-asoma Koch. Syst. Myr., 47 and 116 (varicorne) . 



1851. Isolates Menge. Nen. Schrift. naturf. Gesellsch. Danz., iv, 6 (semisulcatus). 



The name Isolates has always been used by European authors, 

 because Nemaxoma Koch was said to be preoccupied by one of La- 

 treille's genera. 



I find from Agassiz's Nomenclator that Latreille's genus is spelled 

 Nemosoma, a word sufficiently different from Nemaxoma. 



Although this is a small difference between the two genera, never- 

 theless Nemaxovm must be used in place of Ixobates. 



10. PAKA.IUI.I s. 



1869. ParajiiliiN Humbert & Saussure. Rev. etMag. Zool., 155 (olmecus). 

 1884. I'nraliilns Latzel. Myr. Ost. -Uugar. Monarch., 55 (emendation V 

 1887.I'n<'iloji<lHx Bollman. Ent. Amer., 226 (oblfctus). 



I have ascertained that my snbgenus J'tu'-mloj-tdnx, whic.li was based 

 upon the characters of -a male, represents only a certain stage of 

 development, and must be considered as a true synonym of Parajulus.
