284 L. de Niceville — Ntw Butterfiics from tht Indian Jxegivu. [No. 4, 



Described from two males and three females collected by the late 

 Mr. A. K;. de E-oepstor£P, and now in the Indian Museum, Calcutta, and 

 another pair taken by Mr. R. Wimberley in my own collection. 



I have taken this opportunity to figure a male o£ H. albimacula, 

 (PI. XIV, Fig. 9), which is the only other species of the genus occurring 

 in the Andaman Islands, and is not furnished with the " male-mark *\ 

 present in H. rana and all Indian species except H. viola, Moore. 



14. Rapala tara, n. sp., PI. XIV, Fig. 11, d'. 



Habitat : Sylhet, Naini-tal. 

 Expanse: <? , 1*6 ; $, 1*65 inches. 



Description : Male. Upperside, both wings black glossed with rich 

 deep purple-blue in some lights, somewhat as in B. sphinx, Fabricius (a 

 common species in Sylhet and Burma, and figured by Hewitson as Deudorix 

 varuna), but not of so brilliant or rich a shade. Foreiving with a promi- 

 nent round discal velvety black sexual patch on the middle of the disc 

 extending slightly into the discoidal cell and traversed by the bases of 

 the two lower median nervules. Cilia black, on the hindwing white from 

 the second median nervule to the anal angle. Hindwing with the anal 

 lobe marked with a small ochreous spot. Underside, both wings greenish- 

 ochreous. Forewing with two short brownish lines at the end of the 

 cell; a regularly-curved narrow brown discal band from the costa to 

 the submedian nervure. Hindwing with the disco-cellular lines as in 

 the forewing, the discal band also, but outwardly very irregular, 

 finely defined with white ; a similar short oblique band on the middle of 

 the abdominal margin ; a round black spot on the margin in the first 

 median interspace faintly crowned with ochreous ; the anal lobe black, 

 the space beyond sprinkled with black and white ; fine anteciliary black 

 and white lines becoming obsolete anteriorly ; tail long, black, tipped 

 with white. Female . Upperside, both wings dull purple, entirely lack- 

 ing the rich deep purple gloss present in the male. Underside, both 

 wings bright ochreous, the markings as in the male. 



Described from several examples of both sexes obtained in Sylhet 

 by the native collectors of the Rev. Walter A. Hamilt on, also from two 

 females taken by Colonel A. M. Lang, R. E., one at Naini-tal, 5,000 

 feet, on 29th September, the other at Nalaina, near Naini-tal, 4^200 

 feet, on 22nd September, 1887. The blue coloration of the upperside 

 of the male is diiferent from that of any species known to me ; the 

 " male-mark " is also more prominent than in any other species of the 

 genus and different in character ; it is present in R. orseis, Hewitson, 

 but is quite different, and is altogether absent in R. sphinx, Fabricius.
