near tlie ii\xix. The togumen is liood-shaped, ojjcn above, except 

 for the rounded ridge at the rear; the falces are smaller in propor- 

 tion than in balkanica. The aedoeagus is short and broad, and is 

 suddenly reduced at the zone (for this name see Chajiman in these 

 Transactions, 1916, pp. 158, 159), where it tapers off to a fine point 

 with two large cornuti in the vesica. The bristles on the clasps are 

 not plentiful and are fine, those on the tegumen equally fine but 

 longer than usual. The tectorius is develojied on the same lines as 

 in nara, but is shorter, less am])le, and somewhat different in outline. 



The androconia are oblong, evenly rounded distally; 

 the sides of the oblong are of inieqiial length owing to the 

 proximal end of the scale being quite difTerent on one 

 side of the foot-stalk to the other ; on the one side it is evenly 

 rounded, the other being excised, the foot-stalk is not in 

 the centre and thus causes one side of the base to be 

 longer than the other. There are sixteen rows of lamina.

Tarucus roaterstradti, Druce, P.Z.S. 1895, p. 585, pi. xxxii, 

 f. 21 ?. 



This species is described from a female, and Druce says 

 that the upperside is very similar to the upperside of the 

 $ of T. iheophrasius, Fab. 



" Underside perhaps nearest to T. venosus, Moore. Fore-wing : 

 basal streak shorter and nuich broader, and extending down to the 

 submedian nervure, the streak beyond broader and ])laced at a 

 much greater angle, the spots beyond the middle more in line, 

 the submarginal row distinctly separated, and the marginal row 

 smallei". Hind-wing : a broad basal streak from just below the 

 costal margin to the anal angle; a broad streak beyond, also from 

 the costal to the anal margin ; then a series of spots as in T. venosvs, 

 which are more inclined to run parallel with the streaks; then a 

 submarginal row of large distinct spots followed by a marginal 

 row of small spots, the three upper being siin])ly dots, the three 

 lower gradually increasing towards the anal angle and dusted 

 thickly with metallic green scales. The ground- coloiu' of both wings 

 is slightly tinged with yellowish and all the markings are black ; the 

 cilia of both wings black.

The Bornean species is evidently a close ally of venosus, 

 but the unique type is not available for comparison. I
