47. Satyrus (Satyrus) powelli Oberth. 



Satyrus powelli Oberthiir, Bull. Soc. Eniom. France, 1910, p. 333 (Djebel Amour). 



This insect has hitherto been taken only in the Djebel Amour and at Guelt- 

 es-Stel. It varies much in size : the largest cj has the forewing 27 mm. in length 

 and a total expanse of 59 mm., and the smallest <J has the forewing 21 mm. in 

 length and a total expanse of 46 mm. The largest ? has the forewing 28 mm. 

 long and a total expanse of 61 mm., and the smallest ? has the forewing 23 mm. 

 long with a total expanse of 49 mm. 



This species is also variable in other respects : in the males above, the ocelli 

 sometimes have a white central dot and sometimes not ; one very small <^ shows 

 no ocelli on the upper surface, and one rather large cj has the upper of the two 

 ocelli ringed strongly with bufif as in the ? ; two other <J<J have Iboth ocelli with 

 buffs rings. In the ?? the ocelli vary much in size, and I have two with enor- 

 mous black patches with buff rings in place of ocelli. Then in the ?$ the buff 

 rings vary also, and I have one 9 in which they have spread so much that the 

 outer half of the wing above is buff, as in mniszechi, and two or three others 

 more or less intermediate. It is curious, however, that although so variable 

 above, the hindwing pattern below is so very constant.

[Satyrus hansii Aust. and Satyrus sylvicola Aust. 



These two Satyrids are extremely puzzling and in consequence have been 

 treated in many different ways by those LepidoptcrLsts who have written about 

 them. The only final and reliable test will be when the genitalia of these insects 

 are studied comparatively with those of statilinus and fatua { = allionii).
