fui'tliev illustration of the European character of the inscct-faima of the 

 Soutlicrn Caspian, Captain Buxton's collection contains a Trichopteron, 

 Phri/(/anea varia F. (Enzeli, June 30th, a fine $ ), and a small stone- 

 ily, Capiiia (M(;njil, Mid-Elburz, March 28th, 1 $ ), probably identical 

 with our C. nigra, which ai)pears with us about the same time of 

 the year. The Nciiroptera Phmipennia are not yet fully examined, 

 but tlie Mijrmclconidae seem to be re])resented entirely by Eur()[)can 

 species.

3 J c?, 5 2 ?, Tula Kud, duly Itli-Oth ; 2 $ 2 (1 juv.), Enzeli, 

 June 3rd. At sea-level. Tula Rud is a stream falling into the Cas{>ian 

 near 8.W. corner, between Enzeli and Astara. " Always in deep shade 

 by forest stream." 



This beautiful insect has lieen treated at one time as a good species 

 and at another as a fcn-in of the protean C. aplcjidens. Taken ])Y itself 

 one might be allowed to ado[>t the former view. It is found all round 

 the coasts of the Southern C-aspian, having been recorded from Lenkoran, 

 Artschewan. Astrabad, and Krasnowodsk. The two sexes are very similar 

 in appearance, the very dai'k metallic apex of the wings in mature male 

 examples covering al)0ut half the space or more of the o\iter portion of 

 the wings between the nodus and the wing-tip, the colour usually less 

 brilliant in the female. It belongs to a group of forms in which the 

 neuration is somewhat opener than in some of tlie other forms included 

 under C. spJeiuJeus. Its relationship appears to be with C. si/rn/ca from 

 Syria, Malatia, and Egypt on the one hand, and C. trcnisccispica on the 

 other. I have no specimens of the latter, but Bartenef, in his paper oiv 

 Palaearctic and East- Asiatic Calopteryx (Warsaw, 1912), Hgures the 

 wings of the male, which do not seem to differ much from those of 

 the Astrabad C. orimfalis, while the wings of the female, according to 

 his tignre, are apparently hyaline. C. si/riaca has the apex of the wingS' 

 in the male much as in orientalis, but in the female onl}^ the hind wing; 

 is coloured at the apex, and the marking is not so sharply defined on its 

 proximal side, Avhile both males and females occur with unmarked wings 

 (C syriaca hyalina Martin), in this respect agreeing with the Algerian 

 C, exul. In specimens of another form from near Batoum, received 

 from Bartenef under the luune of C. viinrjrelica, the dark colour reachei^ 

 nearer the nodus ; the extent must vary, however, as in his figure of thi* 

 form the apical marking appears to be ver}' similar to that of orientalix : 

 the female has the wings hyaline and the form does not seem to appertain, 

 to the oriciitidis group.
