ZARAX Fruhstorfer, [1914], in Seitz, Grossschmett. Erde 9 : 789. Type-species by monotypy : 

 Taxila teneta Hewitson, [1861], ///. exot. Butts 2 : [89], pi. [45], figs 3, 4 $. 



The name Zarax Fruhstorfer is invalid, (a) as a junior homonym of Zarax Pascoe, 1867 

 {Ann. Mag. nat. Hist. (3) 19 : 410), and (b) a junior objective synonym of Laxita Butler, 1879.

In 1890 (Butts India Burmah Ceylon 3 : 14, 34-36) de Niceville redescribed this genus, 

 on this occasion explicitly designating Zarona jasoda as the type-species.

Boisduval attributed this name to Rambur, from whom — as he explained in a footnote — 

 he had received a communication while the Spec. gen. was passing through the press. At the 

 time of the publication of that work, Zegris was still an unpublished name and it must there- 

 fore be attributed to Boisduval.

 As explained above, Rambur was anticipated in publishing this name by Boisduval, to 

 whom he had communicated it in manuscript.

ZELIMA Fabricius, 1807, Mag. f. Insektenk. (Illiger) 6 : 279. Type-species by monotypy : 

 Papilio pylades Fabricius, 1793, Ent. syst. 3 (1) : 34 [a taxon bearing a name invalid because 

 a junior homonym of Papilio pylades Stoll, [1782] (in Cramer, Uitl. Kapellen 4 (33) : 200, 

 pi. 387, figs A, B)]. 



The position of this name is exactly similar to that of the name Phryne Herrich-Schaeffer, 

 1844, already described. That is, until recently it was invalid, as being a junior homonym 

 of a name (Zelima) published by Meigen in 1800 as the name for a genus of Diptera. Like 

 the name Phryne, the name Zelima Fabricius would have become an available name if the 

 Commission had approved without qualification an application submitted to it on behalf 

 workers in the Diptera that Meigen's Nouvelle Classification — and consequently all the new 

 names in it — should be suppressed under the Plenary Powers. This undesirable result was 

 prevented by the decision to suppress the name Zelima Fabricius for the purposes of the Law 

 of Priority but not for those of the Law of Homonymy, the name so suppressed, being there- 

 upon placed on the Official Index of Rejected and Invalid Generic Names in Zoology as Name 

 No. 1657. This decision was promulgated by the Commission in its Opinion 678, published 

 in October 1963 (Bull. zool. Nom. 20 : 339-342). 



The name Zelima Fabricius was replaced by Billberg by the name Ailus for reasons which he
