distiuguished by the much greener colour of the wings, and in that 

 the green colour runs in a line from primaries to secondaries. The 

 tails are also considerably longer, and it is a more robust insect.

A WORD RESPECTING- CALLEREBIA HYBRIDA. 



BY ARTHUR G. BUTLER, F.L.S., F.Z.S., &c. 



1 do not wish to combat Mr. Graham- Young's views respecting 

 Aulocera, which are, no doubt, quite correct from his point of view, 

 but it is only fair to myself to call attention to the fact that I never 

 described CaUerehia hyhrida as a species ; but, as the name implies, 

 regarded it simply as a cross between C. Annada and C. Nirniala ; it 

 was, indeed, raised to the rank of a species by Messrs. Marshall and 

 De Niceville, but it is hardly fair to tax me w^ith the faults of others : 

 one might as well become a godfather at once ; I have not the least 

 objection to answering for my own sins : that 1 did not describe the 

 form, or series of forms, as a species will be evident if I reproduce 

 here all that I ever gave to the world respecting C hyhrida : — 



" Callerebia htbrtda. 



"Dr. AVatt obtained a series of a CaUerehia exhibiting inter- 

 mediate forms between G. Annada and C. Nirmala. In the coloration 

 of the under-surface of the primaries they agree almost entirely with 

 C. Nirmala, but show the sub-marginal stripe strongly as in C. Annada ; 

 on the under-side of the secondaries they are coloured like C. Annada, 

 but have rounded ocelli varying in number from two to five. In 

 expanse they are intermediate, and, therefore, correspond with C. 

 Scanda in this respect. 



" N.W. Himalayas, up to 6000 feet." 



If the above can be regarded as the description of a new species, 

 I can only say that the Catalogue of Staudinger and Wocke abounds 

 with such species, nay, more, that the species of Petiver and others 

 must be adopted as having a prior claim to those of Linnaeus, for 

 Fapilio sulpliureus or PapiJio candidus, with a description appended, 

 although only intended as part of the description, have equal claims 

 to CaUerehia liyhrida. If it be replied that I label the forms C. hyhrida 

 in the collection, I admit the fact, and also that I label the Aden 

 series of Limnas "ancestral tetramorphic species," yet nobody would 

 suppose that the latter represented a specific name.
