IV. Notes on the Orthoplem in the British Museum. 

 2. The group of Calliptamiui.* By B. P. Uvarov, 

 F.E.S. 



[Road December 7th, 1921.] 



Plate I. 



The re-arranging of the group Calliptamini of the British 

 Museum collection proved to be a very difficult task, 

 because the only revision of this group,"}" though a com- 

 paratively recent one, is in many respects unsatisfactory, 

 the whole system adopted in it being based on purely 

 superficial characters, while a number of species are left 

 out. A more detailed study of morphological characters 

 and especially of the structure of the external genitalia 

 enabled me to clear up, to a certain extent, the generic 

 classification of the group and to establish a system which 

 seems to be more or less natural. As. this my work, how- 

 ever, is nothing more than an annotated list of species 

 contained in the British Museum, and by no means a 

 revision of the grouj), I did not try to study all the types 

 in other Museums, and have left many questions, not 

 definitely settled, for the future monographer of this 

 extremely interesting group. 



Besides the British Museum materials, I included in this 

 paper also some species from the Hoj)e Department, 

 University Musemn, Oxford; I am much obliged to Prof. 

 E. B. Poulton for the loan of the specimens. 



KEY TO THE GENERA.

 longer than broad. Male cerci horizontal, much longer 

 than the supra-anal plate, strongly laminato-compresscd,
