and accompanies an extremely sclerotized fibula adjacent the henia. The Itylos female genitalic structure is more comparable to that described in ELIOT'S Leptotes section. The genus Itylos, whose four taxa show a readily interprétable transformation of structural characters (Table 1 below), is most probably an autochtonous entity of the high Andes. It has previously been mistakenly placed amongst the genera of ELIOT'S Polyommatus-secûon because of poor knowledge of its morphology. Table 1. Characters typifying the taxa /. titicaca, I. fumosus, I. pnin and /. sp. n. of Peru DW ground /. titicaca: violet blue with distinct black margin /. fumosus: deep dark blue with wide black margin /. pnin: luminous blue with suffused black margin I. sp. n.: deep violet with wide black margin VHW postmedian band /. titicaca: undulate and continuous /. fumosus: straight and continuous /. pnin: straight and disjunctive I. sp. n.: undulate and disjunctive uncus of male genitalia /. titicaca: long, straight and narrow /. fumosus: short and bulbous /. pnin: long, straight and thick I. sp. n.: long, slightly curved and narrow gnathos of male genitalia /. titicaca: strong and very long (length almost equalling uncus) /. fumosus: short (half uncus length) /. pnin: strong and quite long (length approaching that of uncus) I. sp. n.: narrow and quite long (length approaching that of uncus) aedeagus of male genitalia /. titicaca: suprazonal and subzonal elements of nearly equal length /. fumosus: subzonal element 3 times length of suprazonal element /. pnin: suprazonal element 3 times length of subzonal element I. sp. n.: suprazonal element about 2.5 times length of subzonal element * * * Acknowledgements - For access to material examined we thank the following curators: P.

It was a particular pleasure to receive comments from Dr. GERARDO LAMAS (Peru-Lima), who kindly read the whole paper in draft and many of his criticism, corrections and suggestions are incorporated in the final text. The correspondences with professor Dr. ZOLTÁN VARGA (H-Debrecen) were very useful concerning taxonomic and biogeographic problems. Mr. J. PÁL (H - Budapest) kindly prepared Figs 67 and 69. We also thank Dr. EMILIO BALLETTO (I-Torino) for informing us late in this study of a forthcoming list of some Andean Polyommatinae and apologize for any misunderstandings or problems resulting from the arbitrary publication dates of names by various journals. It is likely that, had we had additional information earlier, we would have proceeded differently in deference to coworkers.
