8. Julus. 

 1758. — Julus Linne". 



. — Julus, of most authors. 



1847. — Allajulus Koch, Syst. Myr., 46 and 106 (punctatus, etc.). 



1883. — Pachyiulus Berlese. Acari, Myr. Scorp. ital., Fasc. vm, No. 1 (rarius and 



sabulosus). 

 1883. — Diploiulus * Berlese. Acari, Myr. Scorp. ital., Fasc. vm, No. 1 (terrestris and 



dalmaticus). 

 1881. — Julus Berlese. Acari, Myr. Scorp. ital., Fasc. xn (sabulosus). 

 1884. — Ophyiulus Berlese. Acari, Myr. Scorp. ital., Fasc. xn (terrestris). 

 1884. — Brachyulus and Braohyiulus Berlese. Acari, Myr. Scorp., ital., Fasc. xn 



(dalmaticus). 

 1884.. — Typhloiulus Latzel. Myr. Ost. Ungar. Monarch., II, 260 (psilonotus) . 

 1884. — Allaiulus Latzel. Myr. Ost. Ungar. Monarch., n, 264 (nanus; emendation). 

 1884. — Ommatoiulus Latzel. Myr. Ost. Ungar. Monarch., n, 277 (fcetidus). 

 1886. — Tiphloiulus Berlese. Jul. Mus. Firenze, 91 (emendation). 

 1886. — Pachiulus Berlese. Jul. Mus. Firenze, 29 (emendation; varius). 

 1886. — Arehiulus Berlese. Jul. Mus. Firenze, 44 (sabulosus). 

 1886. — BracMulus Berlese. Jul. Mns. Firenze, 90 (emendation; pueiltus). 

 1886. — Ophiulus Berlese. Jul. Mus. Firenze, 63 (emendation; fallax). 



I 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 estsblished by 

 Berlese in his u Julidi del Museo di Firenze," except that the follow- 

 ing changes must be made: Arehiulus must give way to a subgenus 

 Julus, because this division contains the type of Julus. The following 

 orthography should be used: Pachyiulus, Ophyiulus, Braohyiulus 

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

 pamphlet. 



9. Nemasoma. 



1847. — Nemasoma Koch. Syst. Myr., 47 and 116 (varicome). 



1851. — Isobates Menge. Neu. Schrift. naturf. Gesellsch. Danz., iv, 6 (semisuleatus). 



The name Isobates has always been used by European authors, 

 because Nemasoma 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 Nemasoma. 



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

 theless Nemasoma, must be used in place of '• Isobates. 



10. Parajulu's. 



1869. — Parajulus Humbert & Saussure. Eev. etMag. Zool., 155 (olmecus). 

 1884. — Paraiulus Latzel. Myr. Ost. -Ungar. Monarch., 55 (emendation). 

 1887.— Pseudojulus Bollman. Ent. Amer., 226 (obtectus). 



I have ascertained that my subgenus Pseudojulus, which 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. 



* 1884. — Diploiulus Berlese. Acari, Myr. Scorp. ital., Fasc. xn (rufifrons and latzelii).
