differ in gênerai faciès, etc., sufficiently even to hâve been des- 

 cribed, i. e. the Asiatic forms, as a number of distinct species. 



The Genevan form therefore requires a name, a spécifie name, 

 which will become a varietal one, if thèse several forms are finally 

 determined to be ail one species. In either case, it is certainly 

 very remarkable that this species, which belongs to the Micrargus 

 and not to the Argus group of forms should exist in one res- 

 tricted locality in Central Europe and not elsewhere throughout 

 Europe. At Sarepta in South-East Russia, which may for fau- 

 nistic purposes be regarded as rather Asiatic than European, the 

 form may claim to be a distinct species and is certainly nearer 

 as regards the appendages, to Melissa, than to Aegiis or to 

 Micrargus. I propose for it the name Sarepicnsis. 



A spécimen f rom Geok Tepe in the Transcaucasus is the most 

 intermediate spécimen I hâve met with, between Argus and 

 Aegus. The borders are almost white the black chevrons are 

 arrowheaded, the maie armature has the dorsal portion distinct ly, 

 almost typically Argus, the extremity of the clasp is but slightly 

 recessed at the upper margin ; the teeth are small, nine or ten of 

 fair size, but not so large as in Argus and half a dozen towards 

 the lower end very small but large enough to count. The insect 

 is no doubt Argus, the most eastern I hâve seen. We may fairly 

 say that it varies (under some eastern influence) in the same 

 direction that had long previously established Aegus, Micrargus 

 and Melissa. 



An examination of the séries of Argus at the British Muséum 

 gives the following results. Three forms happen to be accom- 

 panied by mounted appendages, thèse are, Micrargus, Butler; 

 Argiva, Str., and Roxana, Gr. Gr., thèse ail hâve the Micrargus 

 form. Micrargus is Japanese, the other two are Central Asian, 

 they ail hâve the white margin and judging by the same cha- 

 racter the following named forms are probably of the same race 

 and are ail Central Asian : Bactriana, Gr. Gr. ; Tomyris, Gr. Gr. ; 

 Alaina, Str. ; Orientalis, Leech ; Barine, Leech, from Japan, would 

 seem to belong to the same race; Micrargus, Butler, being the
