2 Watson, Calinaga, Single Genus of a Sub-family. 



Schill's collection. Another of the three known specimens 

 of this beautiful species is in Mr. Hastings C. Dent's 

 collection. Mr. A. G. Butler described the ? of a Calinaga 

 giving it specific rank under the name of Brahma and, 

 from a careful examination of this rare ? and those of 

 Davidis, also scarce, Mr. F. Moore removed the genus from 

 the Nymphalid sub-family Nymphalince (where as I have 

 before mentioned it was placed by Kirby, and again by 

 Schatz in the Diadenien-gruppe along with the three 

 previous mentioned genera) and in "Lepidoptera Indica" 

 (Vol. II., p. 221) founded a new sub-family of the 

 NymphalidcB to receive this genus, which consisted at the 

 most of three and probably only of two species. In the 

 Entomologist (Vol. 27, p. 100) Mr. W. F. Kirby in a 

 most interesting article on Mesapta says "Oberthlir (Etudes 

 d'Entom., IV., p. 19, pi. II., fig. I.) describes under the 

 Papilionidce, a new genus and species from North China, 

 which he calls Davidina Annandii, and which he places 

 between Calinaga (now recognised as belonging to the 

 Nyniphalidce) and Parnassius" thus Oberthiir evidently 

 included Calinaga in the PapiliotiidcB along with Par- 

 nassius and Davidina. 



It will thus be seen that there exists an amount 

 of uncertainty as to where this most curious genus of 

 butterflies should be placed, and it was with this uncertainty 

 in my mind that I commenced to work out the morphology 

 of the exoskeleton of the genus, and I now am pleased to 

 be able to lay the result before you. The work has been 

 costly; so much so, indeed, that on this account I had 

 been tempted to abandon it, till I received most valuable 

 assistance from M. Charles Oberthiir of Rennes, and the 

 Hon. Walter Rothschild of Tring, who kindly placed at 

 my disposal a number of their duplicates of rare genera 

 which 1 wished to examine, and which I should perhaps
