Mr. H. J. Turner has handed me some specimens of a 

 Glmicoj)syche from Cyprus. He mentions that there was 

 some question as to whether they were G. melanops. 

 I find them to be, so far as I can ascertain, a hitherto 

 unik^scribed species. 



They are very Hke G. melanops in size, and have a 

 similar darlc border to the mngs on the upperside, but 

 are of a darker bhie, whilst beneath they are entirely 

 without the marginal ocelli, which are always present, 

 though not conspicuous in G. melanops. 



In reality the species, for which I propose the name of 

 Glaucopsyche paphos, is very close to G. charybdis, and 

 may perhaps be best defined by comparison of its char- 

 acters with those of that species. It is smaller than 

 (r. charybdis; the largest male before me, with which 

 the largest female agrees in this respect, has an expanse 

 of 30 mm., the smallest 28 mm. G. charybdis hi my 

 very short series varies in expanse from 32 to 35 mm. 

 The colour of G. paphos is a very dark blue, and a dark 

 border to all the wings, often very marked, is always 

 present. G. charybdis, on the contrary, is of quite a 

 pale blue. It also has a dark border, but this is very 

 narrow and well-defined; in G. pajihos it is usually ill- 

 defined and tends to extend along the veins. The spotting 

 of the underside, where one expects to find some dis- 

 tinctive character, does present one such character, but 

 broadly the markings in both are identical. In both 

 species the five large spots on the upper-wing may or 

 may not be increased by one or two more of varying size. 

 The fourth spot may be displaced outward from the regular 

 curve that is typical, apparently more frequently in G. 

 paphos than in G. charybdis. The spots on the under- 

 wings present the 1st, 2nd, and 3rd nearly in line, then 

 the 3rd to 6th in a regular curve, the 7th and 8th as a
