are somewhat larger and the si^ots of the hindwing beneath are a httle less distinct (Leech). Nothing is 

 known about the time of appearance and the habits. 



pang. C. pang Oberth. (77 f). This small but pretty butterfly has a much deeper blue gloss above, beneath 



which the black spots however are quite distinct. The hindwing has a red spot on a tooth-like projection 

 of the anal angle and traces of such spots are found at the distal margin of the forewing. The underside 

 of the hindwing is very characteristic, bearing on a red-brown ground between disc and outer third a 

 white band which is externally dentate. (J ^^^ ? alike, but $ sometimes somewhat paler on the disc of 

 the forewing. — In Sze-chuen, the ^J very common, the $ considerably rarer. 



tseng. C. tseng Oberth. (77 e). Similar to the preceding, but larger, the hindwing with the anal angle less 



pointed and the white band replaced by a pale brown double line which is edged with dark on the outer 

 side. The $ has a distinct reddish yellow spot in the outer half of the forewing above, and the hindwing 

 bears usually a well developed marginal band, which is only interrupted by the veins. -^ In West China, 

 widely distributed, but rarer than fang. 



li. C. li Oberth. (77 e). (J above recalling Zephyrus quercus, black, with a dull blue-violet gloss; anal 



angle of both wings with reddish yellow spots. Hindwing with a rather long tail. $ with large red-yellow 

 spot in the outer half of the forewing and red-yellow lunate band on the hindwing. Beneath the forewing 

 red-yellow, the hindwing red-brown; a heavy white submarginal line across both wings. The disc of the 

 wings has numerous black spots, which are edged with blue on the forewing, with white on the hindwing. 

 Our figures represent the $ (from above) and the (J (from below) of the more strongly spotted summer-brood, while 

 the specimens figured by Obeethue (Et. d'Ent., 11, pi. Y, fig. 34, 38) belong to the spring-brood, which 

 is less strongly spotted on both sides. The former will perhaps receive a separate name in future. 

 - — In West China, very common. 



ouang. C. ouang Oberth. On both sides very similar to the preceding, but the more pointed wings of the 



(J, the brown upperside without gloss and the longer and more acute tail recall yet more strongly a Theda 

 than do 11 and tsejig. Underside much more abundantly marked with white, as the discal spots of the 

 hindwing within the very broad white submarginal band are united to form heavy white lines. — Ac- 

 cording to Oberthue at Tse-kou. This form is unknown to me in nature; the description is based on 

 Oberthur's figure and text. 



sultan. C. sultan Stgr. (= sultani Stgr.) (77 f). At most as large as amphidamas; above black-brown, the 



base of wings with a blue gloss and the whole surface with a weak golden gloss. Beneath white-grey with 

 abundant spots, which form 3 parallel rows in the outer third of both wings; between 'the two outer rows 

 a red band, and between the two inner rows a white one; hindwing with a thin tail. — Turkestan (Hazret 



Sultan Mts.). 



raspius. C. caspius Led. (77 f). Very similar to the preceding but the wings more rounded, the tail longer, 



the 3 parallel rows of spots in the outer third of the hindwing beneath closer together. The gloss of the 

 transiens. upperside rather more coppery than in s}dtmi. From North Persia. — In the form transiens Stgr., which 

 occurs in the Pamir and Turkestan, therefore in certain places together with sultan, the underside is more 

 yellowish, with the spots less prominent, the black spots not being so sharply edged with white; the anal 

 area with more distinct red-j'ellow colour, which appears usually also on the upperside (in the specimen 

 figured the red-yellow is except onally not distinct in the anal area above). In July, especially in the 

 mountains south of Samarkand, not rare. 



sarlhus. C. sarthus Stgr. Above like caspius, differing at the most in the reddish spot of the anal area of 



the fore- and hindwing being more distinct; the fringes of the h'ndwing are distinctly spotted. Beneath 

 the base of the hindwing, however, is shaded with green; the dots of the 3 rows are much more different 

 in size than in the otherwise similar transiens, the spots of the central (submarginal) row being usually 

 very heavy and black, while those of the other rows are very small. A non-tailed form is known and a 

 tailed one {caudatus Stgr., 77 g), the latter occurring particularly in the eastern districts. — Turkestan, 

 especially in the Pamir and Bockhara. The butterfly is on the wing in June and July; it is not rare and 

 occurs in the mountains up to 8000 ft. (e. g. near Samarkand). 



phoenimirus. C. phoenicurus Led. Larger, the wings more elongate, upperside with a much lighter purple gloss, 



so that the abundant black markings of the underside are better marked above. The base of the wings 

 strongly shaded with blue. The underside stronglj^ spotted, with distinct red distal marginal band, which is the 



margelanica. colour of red lead and in the $ very broad. Prom Persia. — margelanica Stgr. (77 f), from Ferghana, is the most 



usual form sold by the dealers. The gloss of the upperside is more violet; the form is considerably larger than 



Persian specimens; the underside more yellowish grej% not so pure ivory-white as in true pihoeni- 



seintillans. curus. — scintillans Christ., from some mountains of Turkestan (Germob), has above distinct black veins on 



dimorphus. a glossy bright purple-red ground. — ab. dimorphus Stgr. are (J^J which are devoid of the blue-violet gloss
