costal margin narrowly dai'k brown. The anal angle to the base 

 of the tail is rather iDroadly black, with a distinct bright green 

 anteciliary line and a gi-een crescent-shaped spot on the inner 

 portion of the lobe. The under side is brownish black, darkest 

 on the hind wing and towards the centre of the fore wing ; the 

 basal areas of both wings are broadly shining emerald- green, and 

 there are four narrow shining green ultramedian lines on the 

 hind wing, the anteciliary line being the most prominent. 



Female. Upper side dull shining slaty blue, with apex and 

 outer margins brownish black ; hind wing with the green anal 

 markings as in male. Under side paler than in male, with the 

 green lines of the hind wing (excepting the anteciliary line which 

 is prominent as is also the green above the black lobe) almost 

 obsolete ; the basal areas of both wings are entirely without the 

 green.

Perhaps nearest to T. hemon Cr.*, but not very nearly allied. 

 The brand is smaller and more prominent. 



Thecla numen, sp. n. (Plate XXXII. figs. 4^,5$.) 



Male. Upper side : fore wing and basal half of hind wing- 

 opalescent greenish blue, deepest towards base. Fore wing with 

 the costa naiTowly and the apex and outer margins more broadly 

 black. Hind wing with a dark mark at the apex and a dark 

 mark between the nei-vules near the anal angle, with its outer half 

 white and the dark stripes of the under side showing through 

 distinctly. Under side with prominent white and brown stripes 

 arranged as in T.phydela Hew.f, but more prominent and without 

 the short white band which commences on the costa near the base 

 on the hind wing ; the yellow area at the anal angle is less, 

 being confined between the lower median nervules. Cilia of both 

 wings pure white on both surfaces. A linear dark brown glandular 

 patch on base of lower median nervule of fore wing occupying 

 about half its length from its origin to outer margin.

 margins broadh^ brownish black, as is also the outer margin of 

 hind wing which, however, encloses a distinct white line just 

 within the black anteciliai'y line. Under side as in male, but

 Cilia of both wings brownish on both surfaces, but whitish 

 towards anal angle of hind wing.
