" Lhutso differe de tous Ics autrcs par la teinte jaunatre de scs tachcs en dessus, le lavis orange 

 qui s otend sur Tangle anal, la couleur jauue ocracce qui fait lo fond des ailcs iuferieures et 

 dc I'apex des snpericures eii dessous. 



" De plus, les ailes sont plus opaques, les parties noires ))lus accentuccs, et la forme des ailes 

 moins arrondic que dans davidi.^ ; ello e^t cependant moins anguleuse que chez huddha. 



" Tso-kou (Thibet), 11. P. Dubcrnard." {Of>eri?iiir, 1. c.) 



This appears to be a very distinct species. M. Oberthiir (I. c.) also records 

 C. huddha from the same locality, but I am inclined to think that tliis 

 is an aberrant form of C. davidis, a species he previously confounded with 

 C. huddha. 



Dichorragia nesseus. 



Bichorragia nesseus, Grose Smitli, Ann. & ^^lag. Nat. Hist. (G) xi. p. 217 (1893). 



" Male. TJppersido dark l)luish green. Anterior wings with the cell crossed by three black bars, 

 that nearest the base nearly obsolete ; beyond tlie cell, across the disk between the veins, is 

 a curved row of indistinct greyish spots, the second and third of which are elongate; a sub- 

 marginal row of sagittate grey markings, elongated inwardly to the extent of about one tiiird 

 of the wings, those towards the apex being more elongate and narrower than the others ; 

 there are no spots on the outer margin. Posterior wings more bluish green than the anterior 

 wings and without grej^ markings, except three small hastate lines near the apex, with grey 

 lines at their base, the lowest almost obsolete ; beneath these, on the outer margin between 

 the veins, is a series of black hastate spots. 



" Underside: anterior wings bluish black, with the spots beyond the cell moi'e distinct and the bars 

 crossing the cell and a small spot beyond violaceous; the sagittate markings .as on the 

 npperside, but more distinct. Posterior wings olivaceous, the hastate spots at the apex as 

 on the npperside, and the series of marginal black spots faintly and veiy narrowly bordered 

 with white. 



" Expanse of wings 23 inches. 



" One example. Omei-shan, Western China. 



"Near to D. nesimacJius, Boisduval, but considerably less maculate." 

 {Grose SmUh, I. c.) 



A figure of this species Avill be given in a future part of ' Exotic Butterflies,' 

 by Grose Smith and Kirby. 



Euthalia strephon.

" Tpperside olivaceous green. Anterior wings crossed beyond the middle from the cost; J to the 

 submedian nervures by a pale greenish-yellow band, widest on the costa, narrowest between 

 the two upper median nervules ; a small yelLwish somewhat elongate spot near the costal 

 margin, and a larger oval spot of same colour at the outer edge of the band beneath it ; the 

 space between and on each side of the dark bars which cross the cell is also jjale greenish 

 yellow. Posterior wings with a pale greenish-yellow curved band following the contour of
