6. Tlic eighth sternite of the aLdomen (PI. XXII. f. 27) slightly bisiimate, 

 the mesial portion almost straight, not distinctly lobed, its edge incrassate internally, 

 having, in a view from tiie aiiical side, tlie apiJeai'ance of lieing turned dorsad, 

 llarpp (Pi. XXXI. f. Ifi) with a long linger-like distnl pro<'ess (jtr), wliich points 

 ventriid ; ti:e mesinl ridge {cm) consisting of two lamellne, irregnlarly dentnte and 

 distally jtrodnced into a cone, the extreme end of wliich is turned vcntrad. Tlie 

 ])enis-sheath (PI. XXX. f. 0) nearly shaped as in mdiuili/era, hnt there is a row of 

 teeth dorsally, and also some irregular teeth ventrally : from the sheatli protrudes 

 a hlunt, somewhat club-shaped "love-dagger." The tentii sternite (PI. XXIII. i". Uj 

 is lobed mesially, the lobe is rather narrow, almost truncate. Process of penis- 

 siieath of typo-specimen suddenly curved ; normal in a second specimen fmni 

 N.W. India." 



?. Vaginal plate similar to tliat of )»iir/i/i/'erii, Imt the mesinl lobe longer and 

 broader. 



Early stages not known. 



JJa/j. North- West India to Tenasserim. 



In the Tring Museum 7 c?c^, '.^ ? ? from: IJandakeit, N.W. India (Mansfield) 

 Sildnm ; Khasia Hills ; Jaintia Hills : Tandong, Tenasserim, 400(1 ft., Mayi 

 (Fruhstorfer). 



The Tenasserim individual is not well jireserved ; it is much more jiale yellow 

 than ordinary .tei-/ce//)e/i)ii.i, and has scarcely a trace of lines on the forewing.

c? ?. A very pale species. Forewing similar to that of sfriceipcn)il.'<, but firsfi 

 discal line, which is the only distinct line, more distal, at W about midway between* 

 cell and the broad yellowish proximal border of the submarginal line : line across 

 ajiex of cell in the same or nearly the same direction as the streak upon W. A 

 subbasal costal patch on forewing. Abdomen in cJ with fine mesial line, no jiatcli 

 on eighth tergitc ; in ? without line. Underside of wings deep chrome (Ridgway, 

 Nomencl. Colours vi. G). 



There are apparently two subspecies : 



((. The pair from N.W. India in the British ]\Iuseum is very pale grey on the 

 forewing ; the line across apex of cell forms an obtuse angle with the line upon 

 R^ ; the round subbasal spot behind cell is small ; the eighth sternite of the S has 

 a truncate-sinuate mesial lobe of which the angles are not distinctly toothed. 



b. The individuals from Sikhim have the subbasal round patch of the forewing, 

 behind cell, enlarged, the line across apex of cell more horizontal, and the angles of 

 the lobe of the eighth sternite produced. 



c?. Tenth sternite deeply sinuate, the two lolies rounded (PI. XXIII. f. S). 

 Eighth sternite mesially with a lobe which is or is not toothed at the angles. 

 Harpe broad (PI. XXXI. f 18) ; distal process {pr) rather short, somewhat 

 concave above, curved downward, obtusely jjointed ; snbmesial i)rocess {pm) hollow.
