Morpho adonis Cram., Morpho adonis major Lathy, Morpho marcus Schaller, 

 Morpho eugenia Deyr., and Morpho uraneis Bates 



Here we find a most awful confusion. Herr Fruhstorfer has stated that 

 eugenia Deyr. is the same as adonis Cram., while he keeps uraneis Bates as a 

 separate species, and he places marcus Schaller as the ? of adonis Cram. The 

 truth is that eugenia Deyr. is not the same as adonis Cram., bat is an insect with 

 much shorter, blunter, and broader wings, and much more silvery blue colour; in 

 fact, it bears the same relationship to the Guiana adonis Cram, as uraneis Bates 

 does to adonis major Lathy from the Peruvian Amazon, which latter is not men- 

 tioned by Fruhstorfer. Now as to M. marcus Schaller : this has been held by most 

 entomologists, including Herr Fruhstorfer, to be the ? of adonis Cram., and it is 

 certainly taken in the same localities with it. However, the only recorded specimen 

 taken in copulation with a c?, and now in the collection of Mr. Ch. Oberthtir , was 

 undoubtedly taken in copulation with a S eugenia Deyr., and not with an adonis 

 Cram. <J. I have two fine ? ? of M. uraneis Bates, as well as three cf c?, and they 

 are exactly similar to M. marcus Schaller, only nearly double the size, and have 

 perfectly rounded hindwings, with no sign of the tail-like anal appendage always 

 present in all Guiana ? ? = marcus Schaller, which have been figured or which I 

 have seen — i.e. two in Tring, several in the British Museum, one in Mr. Kaye's 

 collection, the ones figured by Schaller and Oberthtir, and the photographs I have 

 of eight in the collection of Mademoiselle de Florrack of Paris. In the collection 

 of the late Mr. Adams, now in the British Museum, are the types of Mr. Lathy's 

 M. adonis major, two S S, one ? , collected in Peru by Messrs. H. and C. Watkins. 

 The ? resembles my two ? ? of uraneis Bates, and is probably a small ? of that 

 species, especially from the fact that Mr. Maxwell Stuart, when he took mine on 

 the Rio Cachiaco, collected also a number of $ $ of adonis major. In view of the 

 fact that the only proof we have by actual capture in copulation gives us marcus 

 paired with eugenia, I am inclined to believe that we do not know the true female 

 of adonis. If this is really the case, then marcus antedates eugenia by some eighty 

 or more years, and we have the following two species to tabulate. 



Morpho marcus marcus Schaller, Guiana. 



Morpho marcus uraneis Bates, Pern and Peruvian Amazons. 



Morpho adonis adonis Cram., Guianas. 



Morpho adonis major Lathy, Peru and Peruvian Amazons. 



Mr. Kaye has advanced the theory that eugenia is the dry-season form of adonis. 

 I cannot at present agree to this, as Mr. Le Moult has received considerable series 

 of both taken at the same time, and I have 1 1 c? <$ of adonis major captured by 

 Mr. Maxwell Stuart at the same time and place on the Rio Cachiaco as the uraneis 

 mentioned above. I fear, however, this confusion will not be finally cleared up till 

 adonis ? has been bred or taken in copulation with an undoubted S . 



Morpho cypris schausi subsp. nov. 



S. Above has the wide white band of c. bugaba Staud. from Chiriqui, but is as 

 large as the largest typical c. cypris. Below has even larger ocelli than c. cypris, 

 not the tiny ones of c. bugaba.
