A Revision of the genus Tarucus. 291 



species mixed together that have revealed themselves 

 by their sexual organs. 



I have placed these species in the type section on account 

 of the position of the sclerites that replace the " virgae 

 excitatae," and on account of the aedoeagus and reduced 

 tectorius. 



Tarucus dharta, sp. nov. Plates XIV, fig. 15 ; XVII, fig. 14. 



J. Upperside sublustrous violaceous with brown borders to each 

 wing of moderate width. Underside whitish with brown markings. 

 Primaries with a broad costal band and a broad erect subbasal 

 dash (not wedge-shaped), both much shorter than in T. ananda 

 and more separate; a broad dash across the end of the cell sur- 

 mounted by a spot shifted somewhat outwards; postmedian line 

 consisting of three pair of confluent spots and a single one shifted 

 well outwards, but not touching the submarginal series; the 

 second pair of spots is shifted shghtly outwards and the third pair 

 well inwards; submarginal row composed of six fair-sized inter- 

 nervular sjjots followed by the terminal row of six internervular 

 dashes ; termen finely dark. Secondaries with a broad basal 

 dash, followed by four largish spots below each other, the upper- 

 most costal spot being very large ; these spots are almost confluent ; 

 a reniform mark closes the cell; postmedian series composed of a 

 pair of confluent subcostal spots, three confluent spots shifted 

 outwards and almost forming a broad dash, a pair of confluent 

 spots shifted inwards under the reniform spot; postmechan row 

 composed of eight interneural spots followed by a trace of a terminal 

 row of dashes represented by three fine interneural dashes at the 

 apex and two spots at the anal angle ; termen finely dark. 



$. Both wings brownish with whitish chscal areas and most of 

 the underside pattern showing through. Primaries irrorated on the 

 fold and the discal area with brilliant lustrous blue, and the post- 

 median row of spots showing prominently through. Secondaries 

 with a trace of the blue in the discal area, and a fine series of whitish 

 interneural dashes outside the postmedian row of sjiots showing 

 through. Underside precisely like the male. 



Expanse, o 25; $ 26 mm.

Types in my collection. 



This species may be recognised from ananda in the 

 greater separation of the underside pattern throughout, 

 and especially in the submarginal and terminal lines; the 

 female is markedly different.
