alike in the collection of Mr. Otto MoUer, one of which was taken in Sikkim 

 on llfch July, 1884, another is without date, and the third was taken 

 in Bhutan in April, 1887, also a single female in the collection of Mr. 

 G. C Dudgeon taken on 6th May, 1887, also in Sikkim. 



Whether A. nijpalicus, A. rukma, A. ruhmini, and A. sani are four 

 distinct or one protean species must remain undecided for the present. 

 The ground-colour of A. nipalicus and A. ruhma is the same on the 

 underside, viz. yellow, but the former has the bands and spots marked 

 with a silvery line, while the latter has not. The colour of A. ruJcmini 

 is dull Indian-red or stone-colour, bands marked with a silvery line ; 

 of A. sani cinnamon-red, with no silvery line. By these characters, as 

 far as my specimens go, the various species can be readily distinguished, 



13. HORAGA RANA, n. sp., PL XIV, Fig. 10, d". 



Habitat : South Andaman Island. 



Expanse : d*, 1*15 to 1-25 ; $ , 1-20 to 1*35 inches. 



Description : Male. Upperside, both wings differ from H. albima- 

 cula^ Wood-Mason and de Niceville, in the violet-blue coloration being 

 replaced by pure caerulean blue. Forewing in having the oval white 

 discal patch smaller, bounded by the lower discoidal and first median 

 nervules, in one specimen only extending very slightly into the sub- 

 median interspace, divided into three portions by the black crossing 

 nervules ; in one specimen there is a considerable patch of pure ceerulean 

 blue scales on the basal half of the wing below the median nervure, which 

 patch is obsolete in another specimen and entirely absent in a third. 

 Underside, forewing differs in having the median white band extending 

 conspicuously almost to the costa and pure white throughout, the anterior 

 portion of it not washed with fuscous as in H. albimacula. Hindwing 

 with the median white fascia on the average twice as broad ; this, 

 however, is a variable feature in both species. Female much larger than 

 the male in three out of four specimens. Upperside, forewing with the 

 discal white patch twice as large, extending from the subcostal almost 

 to the submedian nervure, and proportionally broad ; a few pale grey- 

 blue scales placed below the median nervure towards the base in two 

 specimens. Hindwing with some scattered pale grey-blue scales on the 

 disc. Underside, both wings bright fulvous. Foreiving with the discal 

 white patch almost touching the costa, its anterior portion narrow and 

 outwardly slightly hooked ; the ground-colour beyond the white patch 

 increasingly to the costa f ascous ; inner angle and margin pale. Hind- 

 wing with the outwardly-diffused discal band outwardly bordered by a 

 pale fuscous fascia, widest at the costa and obsolete at the third median 

 nervule. Otherwise as in H. albimacula.
