CORRECTION OF A MISIDENTIFICATION— 

 ATTACUS SPLENDIDUS. 



By Harrison G. Dyar. 



In the revision of the genus Attacits by Mr. Neumoegen and my- 

 self (Journ. N. Y. Ent. Soc. 11, 122), we recognized two species as 

 possibly occurring in the United States, erycina (^splefididus) 2,x\A j'orulla. 

 Recently in comparing Cramer's plate 68 A with Maassen and Wey- 

 mer's figs. 32 and 34, both of which are given by Kirby under the 

 references for erycina, I find that the species is an entirely different one 

 from that which we had before us and described under that name. The 

 misidentification is an old one. In the first volume of Entomologica 

 Americana is a comparison of the two species in question, from which 

 it is obvious that the " splendidus " there referred to is the same as the 

 one in the Neumoegen collection, namely orizaba Westwood. Later in 

 the same journal, Mr. Neumoegen is quoted as stating that splendidus 

 and orizaba were identical ; but Mr. Neumoegen had never seen the 

 figures o{ splendidus, and depended upon his collection. Probably the 

 inclusion of splendidus in Mr. Grote's list of 1882 is based on the same 

 misidentification, and it may even prove traceable back to Clemens in 

 i860. Our species should stand : — 



Attacus orizaba Westwood. 



1853 — Westwood, Pioc. Zool. Soc. Lond. p. 158, pi. 32, fig. 2. 



i860 — ? Clemens, Proc. Acad. Nat. Sci. Phil. 160 (as splendidus.) 



1882 — Grote, Check List, p. 20 (as splendidus.') 



1884 — Murtfeldt, Can. Ent. XVI, 131 (as ductus). 



1885 — Hulst, Ent. Amer. I, 78 (as splendidus). 



1885 — Neumoegen, Ent. Amer. I, 160 (as splendidus). 



1891 — Smith, List Lep. p. 31 (as splendidus). 



1894 — Neumoegen and Dyar, Journ. N. Y. Ent. Soc. II, 122 (as erycina). 



As to our other Attacus, recorded from Arizona, A. jorulla 

 Westw., I believe that it has a much more extended synonymy than 

 that given by us. A. betis Walk., A. arethusa Walk., A. bolivar 

 Maass. & Weym., A. maurus Burm., A. cinctusTe^pp., and -4. speculum 

 Maass. & Weym., are among the forms which seem to be synonyms or 

 local forms oi jorulla. This matter will, however, find a more suitable 

 place of treatment when the whole genus is monographed.
