18y7.] LITTLE-KNOWN BUTTERFLIES FROM INDIA. 450 



to have gone out of his way to emphasize the fact that his species is 

 a female ; judging from his figure alone, I should have said that it 

 was taken from a male, and that my specimen (which is unquestion- 

 ably a female) was of the opposite sex. The matter must remain in 

 abeyance till some one will examine the sex of Hewitson's type. 



Described from a single example in the collection of Mr. Otto 

 MoUer. 



Tajuria albiplaga, n. sp. (Plate XXXIX. figs. 1, S ; 2, $ .) 



Hai, Sikkim. 



Expanse. S 1'5, 2 1"6 inch. 



Male. Upperside: both wm^fs cerulean blue with hardly any 

 gloss ; cilia grey throughout. Fore wing with the costa bounded 

 posteriorly by the subcostal nervure, the apex broadly (including 

 the anterior portion of the cell) and the outer margin decreasingly to 

 the anal angle black. Hind wing with the costal margin and apex 

 Hght fuscous, the two fine tails black, tipped with white, a fine 

 anteciliary black line. Underside: both wings grey, of the same 

 shade as in T.jehana, Moore '^ ; a prominent narrow, straight, dark 

 line on the discocellular nervules. Fore wing wiih a similar discal 

 line not reaching the costa anteriorly, touching the submedian ner- 

 vure posteriorly; beyond this line is a somewhat similar, but indi- 

 stinct line. Hind wing with a discal line much as in the fore wing, 

 but reaching the costa and recurved to the abdominal margin, the 

 upper portion straight as far a^ the third mecUan nervule, below this 

 the line is formed of outwardly convex lunules ; beyond the discal 

 line is an obso'ete submarginal line as in the fore wing ; a small 

 deep black round spot in the first median interspace, close to the 

 margin and another on the small anal lobe, both outwardly margined 

 with pale yellow ; no secondary sexual characters. — Female larger, 

 both wings broader, the apex of the fore wing less acute. Upper- 

 side : both wings of a slightly darker shade of blue than in the 

 male ; cilia white throughout. Fore wing with a large quadrate 

 diffused white patch on the disk, its inner margin well defined by 

 the discocellular nervules, and that portion of the median nervure 

 between the bases of the first and second median nervules. Under- 

 side marked exactly as in the male. 



Near to Tajuria diceus, Hewitson ^ from Sikkim, but the blue 

 coloration of the upperside is much lighter ; the discal line on the 

 underside of the fore wing in T. diceus is much straighter, its 

 edges more even, and it increases in width to the costa, which it 

 quite reaches ; the colour of all the hues being somewhat rufous 

 also in that species. In T. diceus female, which sex I have not 

 seen, there is a submarginal band of brown spots on the upper- 

 side of the hind wing. T. albiplaga '\s also allied to T.jehana^, 

 Moore, but the sexes of the former differ considerably, while in the
