NOVITATES ZOOLOGICAE XXVI. 1919. 7 



Castnia (Castniomera) atymnius afi&nis Houlb. 



Caatnia affinis Houlbert, Etud. Lipid. Comp. fasc. xiii. p. 57 (1917) (Columbia). 



This may only prove to be an aberration of humboldti, but for the present 

 I keep it separate. Two specimens only are in the Tring Museum. 



1 cJ Rio Negro (ex coll. Felder) ; 1 3 Coreato, Cauca Valley (Paine and 

 Brinkley). 



Castnia (Castniomera) drucei Schaus 



Castnia dnicei Schaus, Ann. d:. Mag. Nal. Hist. (8)7. p. 191 (1911) (Costa Rica). 



The Tring Museum series consists of 17 specimens : 



1 ? Guapiles, Costa Rica, May (W. Schaus) (cotype) ; 2 <J<J San Mateo, 

 Costa Rica, 1—2,000 ft., November 25— December 12, 1906 (W. Schaus) ; 



7 <J<J, 2 ?? Ascazu, Costa Rica, August — October 1903 (Underwood) ; 2 cJtJ 

 Bogava, Chiriqui, 800 ft. (Watson) ; 1 3 Costa Rica (Underwood) ; 1 cJ Pacific 

 Slope, Guatemala (Salvin, ex coll. Felder). 



Castnia licus (Drury). 



Papilio licus Drury, lllust. Nat. Hist. vol. i. p. 30. pi. xvi. £f. 1, 2 (1770) (Surinam). 



The Tring Museum possesses 5 specimens of this excessively rare species, 

 including a ? out of the Van Lennep collection which must have been examined 

 by Cramer though he figures a (J. I should have considered all the forms treated 

 by Messrs. Houlbert and Oberthiir under licus, licoides, and licoidella as sub- 

 species of licus without hesitation, but I have a large series of specimens from 

 British, Dutch, and French Guiana which agree with licoides and differ remark- 

 ably from the 5 true licus. It will most likely turn out that the genitalia of 

 licus and the licoides forms are quite different, but I must leave the settling 

 of this question and also the detailed description of licus to be published in 

 Dr. Jordan's monograph. 



1 (J, 1 $ Surinam (ex coll. Van Lennep, ex coU. Felder) ; 1 $ ? (ex coll. 

 Felder) ; 1 <J, 1 ? ?. 



Castnia licoides Boisd. 



Castnia licoides Boisduval, Spec. Gen. Lepid. HH. p. 527. pi. i. (1874) (Sta Catharina). 



This is a very widespread and variable species, and I do not feel competent 

 at this moment to describe the S3Veral unnamed subspecies and shall only treat 

 them as Mr. Oberthiir has done as races as yet unnamed. 



The Tring Museum has 41 specimens from the following localities : 

 1 (J Bahia, 1 <J, 1 ? ? (probably Bahia) (ex coll. Feld.) ; 9 <?(?, 2 ?? Amazon 

 River; 6 (JcJ, 1 ? Ega, Amazons (Bates, ex coll. Felder) ; 3 cJcJ, 3 ?? Itaituba 

 to Obidos, April 1906 (W. Hoffmanns) ; 1 ^, 1 $ Obidos, Amazons, October- 

 November 1904 (M. de Mathan) ; 2 (J<J, 3 ?? Yuhuty, Amazons, April 1905 

 (M. de Mathan) ; 4 <J,J, 2 $$ Rio Janeiro ; 1 <J Para 1893 (Stuart). 



Castnia licoides subsp. ?
