HETEROCERA OF SIKHIM AND BHUTAN. 301 



Genus Camplyotes, Westw. 

 586. C. histrionieus, Westw. 

 Sikhim, 3,000 to 5,000 feet {histrionieus, 2 forms) ; Sikhim and 

 Bhutan, 9,000 to 10,000 feet, {sikhimensisj 2 forms). Of the two 

 forms of hiatrionicusj one has the red markings on both wings pro- 

 nounced and bright, the other having them pale and dull. I think 

 that sikhimensis, Elwes, is a good species and I have never seen 

 intermediate forms. Mr. Elwes records histrionieus, var. altissima 

 from 10,000 feet, which seems to me to show that sikhimensis, which 

 also occurs there, is not a mere high elevation fonii of histrionieus. 

 Sir George Hampson also includes a var. excelsa, Oberthur, which I 

 have not seen. (C. sikhimensis, C. altissima and C. excelsa I continue 

 to regard as good species as I have seen no specimens from Sikhim or 

 elsewhere which are intermediate between either of these forms and 

 C, histrionieus, and as they appear to be confined to much higher 

 altitudes.— £?. J, E. ) 



588. C. athinsoni, Moore. 



Sikhim, 8,000 feet. May. (This species seems to be local but com- 

 mon where it occurs, which, as far as I know, is only in the interior 

 of Sikhim.— ZT. J. E.) 



Genus Cadphises, Moore. 



589. C. maciilata, Moore. 



Sikhim. I have only seen two specimens of this species in Dr. 

 PiJcher's collection. It seems to me to be quite distinct from the next 

 species, the inner margin of the hindwing being yellow or buflf, 

 unmarked with white spots. 



590. C. moorei, Butl. 

 Sikhim and Bhutan. I have only one male from Bhutan, which is 

 easily distinguishable from the two specimens of C. maculata I have 

 seen, in that the spots are fewer, round and obsolescent towards the 

 outer margins, the inner margin of the hindwing is spotted with white, 

 and the ground-colour is brownish-fuscous. 



Genus Isbarta, Wlk. 

 592. /. imitans, Butl. 

 Sikhim and Bhutan. Occurs at low elevations in the hot valleys 

 pf the larger rivers in April and May,
