A Revision of the genus Tarucns. 289 



in detail, though I have omitted a number of locaUties 

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



M. Oberthur writes me that he has theophraslus in 

 considerable numbers from Biskra, Bon Saada, Djurjura 

 and Scbdou. From the second-named locality there are 

 two medilerraneae and one theophrashis in the Tring 

 Museum ; 210 doubt, taking into consideration my dissec- 

 tions, both species will be found in the Uennes 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 iheo- 

 ])hnisliis 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 medilemoieae these lines were continuous, sometimes 

 fine, but often very broad and heavy. This would, there- 

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

 the specimens. 



I found that this was confirmed in llieophnislns 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 soiuewliat ovate, but truncated distally into 

 a broad arc, the proximal extremity being asynnnctrically ovate 

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

 of lamina widely separated with the sculpturing very deiined and 

 well apart. It frequently hai)|K'ns that abnormal androcojiia are 

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

 with the normal one of this species.
