Chamberlin — Notes on the Julidae and Nemasomidae 9 



The Brachyiulus pusillus of Verhoeff described in the same place (Op. 

 cit., p. 152, pi. 6, fig. 27) is not pusillus of Leach. 



Ophyiulus pilosus (Newport). 



1842. Julus pilosus Newport, Proc. Ent. Soc. London; also Ann. Mag. 

 Nat. Hist., ser. 1, XI, p. 316. 



1847. Julua longabo C. Koch, Die Myriap., II, p. 106, fig. 228. 



For the later synonymy see our previous paper (Proc. Biol. Soc. Wash., 

 1921, XXXIV, p. 83). 



As long ago as 1893 (Ann. Mag. Nat. Hist., ser. 6, XI, p. 249), Pocock 

 pointed out that the types of Julus pilosus Newport were the same species 

 as Julus fallax Meinert (1868), not of Latzel (1884). This identification 

 has been more recently confirmed after reexamination of the types by the 

 Brade-Birks (Ann. Mag. Nat. Hist., 1919, ser. 9, III, p. 254). Hence 

 pilosus Newport, having precedence over longabo Koch as above indicated, 

 must be used in designating this species. 



NEMASOMIDAE. 



The type of Nemasoma, Nemasoma varicorne C. Koch (Syst. d. Myriap., 

 1847, p. 116), is the same species as the type of Isobates, Isobates semisul- 

 catus Menge (Neueste Schr. d. nat. Ges. in Danzig, 1851, IV, 4 Hft., p. 6). 

 Hence Isobates is clearly a synonym of Nemasama. However, Isobates has 

 continued in use in Europe apparently because Nemasoma has been regarded 

 as preoccupied by a genus of Coleoptera proposed by Latreille in 1804 

 (Hist. Nat. Ins., XI, p. 239). The original spelling of Latreille's genus is 

 Nemozoma (vifuo, possess, and i'ui/j.a, girdle), subsequently varied by 

 Curtis and others to Nemosoma. This is certainly sufficiently different in 

 spelling from Koch's genus, which also has a different derivation (vTJfia, 

 thread, and a-utxa, body). The name Nemasoma was also subsequently 

 proposed for a genus of Coleoptera, different from that of Latreille, by 

 Solier (In Gay, Hist. Chile, 1851, V, p. 10). This genus of Coleoptera must, 

 of course, receive a different name. There is no reason, however, why 

 Koch's Nemasoma should not be used in place of Isobates, which it antedates 

 by four years, and the name of the family be correspondingly Nemasomidae, 

 proposed by BoUman as a subfamily in 1893. 



Nopoiulus minutus (Brandt). 



1841. Julus minutus Brandt, Recueil, p. 89. 



For later synonymy see Proc. Biol. Soc. Wash., 1921, XXXIV, p. 83, 

 under Nopoiulus pulchellus. 



This species has been quite widely listed under Leach's name pulchellus; 

 but recent examination of the types has shown that they lack eyes and are, 

 in reality, the same as Blaniulus guttulatus (Bosc), the latter name having 

 the priority.^ Hence, with this transfer of pulchellus to a position of 

 synonymy in Blaniulus, Brandt's name minutus becomes the valid designa- 

 tion of the present species.
