A Revision of the genus Tarucus. 283 



fine point extending to the apex of the chisps; the bristles are 

 longish, moderately stout, but not numerous ; the tegumen is fairly 

 large of the usual pattern with strong falces; the bristles being 

 finer and shorter than those of the clasps ; this is, however, usual ; 

 the aedoeagus is long and waved ; the vesica being finely shagreened, 

 and the tectorius ample and of the usual shape ; it is, I think, the 

 largest in the genus. The androconia are very broad, and were it 

 not that one side of the proximal extremity is excised, it would 

 form an evenly-shaped oblong ; the foot-stalk is given off centrally ; 

 there are seventeen rows of lamina rather widely separated, whose 

 sculpturing is somewhat small. 



Section II contains three species, T. grammica, G. -Smith, 

 T. syharis, Hopffer, and T. quadmius, Grant. The first is 

 a species from Mombasa and from Somaliland, the second 

 a widely-spread, if local, South African insect, and the last 

 a species from Socotra. 



The genitalia in all of these lack the horn-like sclerites 

 which are so peculiar a character of the first section ; 

 quadratus, however, has developed a tusk-like extension 

 of the upper apex of the clasps, and thus forms a connecting 

 link with Section III, containing only the type of the 

 genus. All three species in Section II have the same type 

 of aedoeagus as has Section I.

^. Both wings dark brown. Primaries with a darker spot 

 closing the cell ; secondaries with a terminal row of sf)ots encircled 

 with white, more prominently on the inner side. There is a trace 

 of a similar row of spots on the termen of the primaries, but it is 

 very obscure. Underside white with the markings of the primaries 

 large. From the spot closing the cell in the primaries there is a 

 short, broad dash forming an L with the cell spot ; the broken seiies 

 of marks outside this is united into an irregular band, very broad 

 below vein 2; the postmedian series of spots is pushed far out, 

 near to the subterminal series,' the former being composed of fair- 

 sized spots increasing in size towards the inner margin where they 

 coalesce, the latter consists of six internervular smaller spots; 

 the usual basal dash and subbasal wedge-shaped mark are ])rcsent. 

 Secondaries : a basal subcostal dash with a spot below it, followed
