165. Triphysa phryne, Pall. 



Neither Herz on the Lena nor Dorries in Kentei seem 

 to have found any form of Tri^^hysa, but I have specimens 

 from Grum-Grshimailo's collection taken at Krasnoyarsk, 

 and at some place in Northern Siberia, the name of which 

 I cannot decipher. Jacobson also found it common in the 

 Upper Yenesei Valley. The name Dohrnii was given by 

 Zeller to a single specimen, locality unknown, which had a 

 whitish border to the wings, and there were a considerable 

 number of specimens in Grum-Grshimailo's collection, 

 taken in the Nan Shan Mountains and the province of 

 Amdo, in which this character is Avell marked. The 

 females of this form all show two conspicuous black spots 

 on the upperside of the fore-wing, and in some cases 

 have two small black spots above them, but not in line ; 

 on the underside the position of these spots is much 

 better seen and is in all the specimens markedly different 

 from those of typical phryne from Sarepta, which are in a 

 regular curved series following the line of the outer 

 margin. Four pairs, which were collected by Leder in 

 some part of Northern Mongolia, or perhaps in the 

 Irkut Valley, show these differences in a less marked 

 degree, but I am disposed to separate them at least as a 

 variety from 2Jhry7ic. There is also a form described by 

 Erschoff as albovenosa, and figured in Rom. Mem. Sur. Lep. 

 II, PI. XVI, fig. 20, which he says was taken in the Amur 

 Valley far east of Blagoveschenk, which appears to me 

 only a variety of iihrync, with the spots undeveloped. Staud- 

 inger in Rom. Mem. Sur. Lep., vi, p. 208, treats this name 

 as synonym of nervosa, Mots., which he puts as probably a 

 variety of phryne. Nervosa was described from Japan, 

 but as no specimen of any Triphysa has reached Europe 

 from Japan, so far as I know, this is probably a mistake. 

 The only female specimen I have from the Amur has no 

 ocelli above on either surface, and only faintly marked 

 ones on the hind-wing below. It appears to me on the whole 

 that there are two or three well-marked forms of this genus; 

 phrync extending from Sarepta through the steppes and 

 mountains of Western and Central Siberia to some un- 

 known point, possibly in the longitude of Lake Baikal 

 with a more or less marked variety albovenosa, Erschoff, 

 vel. nervosa, Mots., from the Amur Valley; secondly, a 

 form extending from Northern Mongolia southerly to the
