occur at a lower altitude than M. pharte. He himself had 

 found j\r. melamims abundantly in various localities, at from 

 3,500 — -1,500 feet, in Piedmont, the Tyrol, etc. ; but M. ■pharte 

 occurred rather from 5,000—7,000 feet. Mr. Tutt said that 

 his attention was first drawn to the species by some very fine 

 examples captured at about 4,500 feet elevation, on Mont de 

 la Saxe (Courmayeur), on Aug. 1st, 1895, by Dr. Chapman 

 and himself. It was suggested to him that these specimens 

 were Erehia erij^hi/le, but he was of opinion (and this opinion 

 was shared by Mr. Elwes) that the specimens represented 

 vielampus. Compared, however, with Tyrolean (Campiglio, 

 Mendel) examples of the latter, these exhibited a tendency to 

 a lengthening of the forewings and to an obsolescence of the 

 black dots, thus coming in these particulars somewhat near 

 pharte; but the females were very like the males, and pre- 

 sented none of the typical characters of female jiharte. These 

 specimens were exhibited. Returning to the Lautaret cap- 

 tures, which were all taken together, flying in the same field 

 (some in cojmld), it will be observed, from the specimens 

 exhibited, that the males run from typical melampus, with four 

 or five black dots in the fulvous band, through specimens with 

 3, 2, 1, and no black dots, i.e., to typical male pharte. The 

 shape of the wings, too, varies from the typical rounded- 

 winged melampus to the more pointed-winged pharte, some 

 of the specimens which are pharte, so far as their unspotted 

 band goes, being melampua by the rounded character of the 

 apices of the forewings. The females are all typical pharte, 

 with a band more orange than fulvous, and with the band 

 distinctly pale, as in pharte, on the underside. It would 

 appear that here (Lautaret) vielampus and pharte form 

 but one species, however distinct they may be in some dis- 

 tricts. Of course it would be easy to separate the spotted 

 forms from the unspotted forms, and call the former melampus 

 and the \a.ttev pharte, but it would not get over the difficulty 

 of the females being all of one form, nor of the fact that a 

 proportion of the melampus-slm^^ed males are unspotted, and 

 vice versa, nor of the fact that some of the males which are 

 typical melampus were paired with typical female ^/larie. The 

 species were not uncommon in the flowery meadows, but
