184 PKOCEEDINGS OF THE AMERICAN ACADEMY 



1816. Hiibn., Yerz. 100 : Carinenta, celtis. 



Besides tlie reasons given in tlie introduction for believing that Hiib- 

 ner's Verzeichniss did not appear until after 1816, wliiclx alone would 

 be enough to give Ochsenheimer the preference in this case, Ochsen- 

 heimer's preface is dated in March and Iliibner's in September. One 

 must have borrowed from the other. It is beyond credence that both 

 should have coined the same generic word for the same insects, unless 

 there were some special significance in the name, as there is not. 

 Iliibner's genus was defined (briefly), while Ochsenheimer's was not; 

 but the latter author gives a reason (an insufficient one) for changing 

 the name of the earlier Libythea, just as he does m the case of Char- 

 axes ; and there can therefore be little doubt that the genus is to be 

 credited to Ochsenheimer. In that case, the genus cannot stand, for 

 celtis (which is generically distinct from Carinenta) had already been 

 taken as the type of Libythea. See also Ilypatus. 



501. Hecalene.* 

 1844. [Boisd. in] Doubl., List Br. Mus. 112: Clytemnestra. Sole 

 si^ecies, aud therefore type. 

 But this name must fall before Hypna (q.v.), as pointed out by 

 Westwood, in the Genera of Diurnal Lepidoptera, where Hecalene is 

 credited to Boisduval. 



502. IIectortdes. 

 1822. Hiibn., Index : Agavns, Brunichus. 

 1822-26. lb., Exot. Schmett. ii. : Lysithous, Ascanius. 

 1825. lb., Zutr. iii. 25 : Proneus. 



The choice of type must, of course, lie between Agavus and Bru- 

 nichus, and Agavus may be selected. 



503. IIedone.* 



1872. Scudd., Syst. Rev. 58 : Brettus, Prcecejis, Coscinia, Orono, 

 JEtna. Brettus specified as type. 

 It falls before Thymelicus (q. v.). 



504. IIelcyra. 



1800. Feld., Sitzungsb. Acad. Wien, xl. 450 : Chionippe. Sole spe- 

 cies, and therefore type. 

 1861. II)., Neues Lep. 37, 44: the same. 



505. Helias.* 

 1807. Fabr., 111. Mag. vi. 287 : no insects cited, excepting an unnamed 

 MS. species. 

 The description is also entirely insufllcient to give any clew to what 

 Fabricius may have had in mind, and hence the name must be dropped.
