A Revision of the genus Tarucus. 289 



in detail, though I have omitted a number of localities 

 from where very few or only one specimen were sent home. 



M. Oberthur writes me that he has theophmslus in 

 considerable numbers from Biskra, Bon Saada, Djurjura 

 and Sebdou. From the second- named locality there are 

 two mediterraneae and one theophrastus in the Tring 

 Museum ; no doubt, taking into consideration my dissec- 

 tions, both species will be found in the Rennes Museum 

 also. 



After my dissections had been done, I sorted the species 

 in accordance with those results, and they gave me a 

 fairly easy rule of separation. I found that all my theo- 

 phrastus dissections came from specimens in which the 

 postmedian lines in both wings were separate spots, not 

 confluent ; in the hind-wing they were frequently more or 

 less fine lunules, but not a continuous crenulated line ; whilst 

 in mediterraneae these lines were continuous, sometimes 

 fine, but often very broad and heavy. This would, ther^ 

 fore, seem to be a fairly safe character whereby to separate 

 the specimens. 



I found that this was confirmed in theophrastus from 

 India and other parts of Africa, in all of which the post- 

 median lines are composed of separate spots or lunules. 



The androconia are somewhat ovate, but truncated distally into 

 a broad arc, the proximal extremity being asymmetrically ovate 

 with the foot-stalk given off non-centrally ; there are twelve rows 

 of lamina widely separated with the sculpturing very defined and 

 well apart. It frequently haj)pens that abnormal androconia are 

 present, and I have figured one of tliese found on the same wing 

 with the normal one of this species.

(J. Upjierside deep lustrous violaceous with a distinct dark border 

 of moderate width in each of the wings, quite markless except that 

 the underside spots show through indistinctly. Underside, whitish 

 with dark marks and spots. Primaries with a broad basal costal 

 stripe, and an irregular, broad (not wedge-shaped) dash ascending 

 to it from the inner margin, outside which is a short, very broad
