146 MESSES. H. J. EL WES AND JAMES EDWARDS : 



Hal. Margherita, Assam, E. Pegu (Doherty) ; Malacca (Pinwill) ; Tameang Lajang, 

 S.E. Borneo (in coll. Rothschild). 



Tagiades tabrica. 



Pterygospidea tabrica, Hewitson, Exot. Butt. v. pi. lix. fig. 8 (1873). 

 Celcenorrhinus tabrica, Watson, Hesp. Ind. p. 143 (1891). 



Hal. Darjeeling (Rolerts, fide Hewitson). 



Hewitson's type in the British Museum is a male, and it is very remarkable that if 

 it really came from Darjeeling no other example has since been obtained. 



Tapena. 

 Tapena, Moore, Lep. Cey. i. p. 181 (1881) ; Watson, P. Z. S. 1893, p. 60. Type thwaitesi, Moore. 



A genus of few species closely allied to the next, but distinguished by the single 

 angulation of the termen of the hind wing, which occurs at the apex of vein 3. 

 The hyaline spots in the fore wing of the male in all the species known to us are 

 present only in cells 6, 7, and 8, but there is sometimes an indication of two others 

 in cells 10 and 11 ; in the hind wing there is sometimes one in the cell near the 

 transverse vein. 



In the males the clasp is wider than usual, and the upper lobe is developed into one 

 or more processes which, when in situ, lie upon the back of the tegumen and evidently 

 effect the depression of that organ in proportion as the inner faces of the clasps 

 approach each other. This structure is also found in the males of Ctenoptilum. 



The following is a table of the species at present known to us : — 



Males. 



1 (2). Upper lobe of clasp bifid at the apex thwaitesi, Moore. 



2 (1). Upper lobe of clasp not bifid at the apex. 



3 (4). Upper lobe of clasp with three limbs, all of which are serrate. Similar 



to ihivaitesi, but smaller and paler above minuscula, n. sp. 



4 (3). Upper lobe of clasp with two limbs, of which the lower is serrate and 



the upper simple. Size of thwaitesi, but upperside in the male 



nearly uniform dark umber-brown hampsoni, n. sp. 



! Tapena thwaitesi. (Plate XXII. fig. 15.) 

 ? Tapena thwaitesi, Moore, Lep. Cey. i. p. 181, pi. lxvii. figs. 2, 2 a, <$ (1881) ; Watson, Hesp. Ind. 

 p. 122 (1891). 



Hal. Perak (Doherty) ; Selesseh, Sumatra (in coll. Rothschild) ; Kina Balu, Borneo 

 (Waterstradt); Chindwin District, Burmah (Adamson). 



As we have not been able to examine the clasp-form of a Ceylon specimen of 

 T. thwaitesi, it is possible that we have not correctly identified it.
