tlie exception of tlie extremes of the inner edge ; uniformly 

 yellow in tigris. The mottling of the underside of the hind- 

 wing also has considerably more yellow in its composition 

 than is the case in true tschudica. 



Two males approach menestJw in the richness of the under- 

 side coloration ; one approaches dyala in the poverty of it. 

 The extent of the orange in the apical pafch of the forewing 

 above is, on the average^ appreciably greater than is the case 

 in dyala.

Underside of the hind wing lighter and more yellowish 

 than in true lyssa, Bois., in that respect agreeing with 

 Herrich-SchafFer's description of megcBrina. Herrich- 

 Scliaffers states, however, that the upperside of his 

 megaerina is that of Hiibner's fig. 914, i. e. lyssa. The upper- 

 side of iranica is more that of Staudinger's transcaspica, i. e. 

 with the much obscured hindwiug, but the underside of 

 the hindwiug is much darker than in that form. The 

 specimens are all rather smaller than the transcaspica and 

 lyssa in the B.M.

In addition there are in the B.M. one pair from Dizful, 

 Persia, and a further pair from Teheran which belong to 

 this race. A pair from Gulek, Taurus, though much larger, 

 agree in all other respects. It is probable, too, that the 

 specimens mentioned by Le Cerf (/. c. p. 41), from Persia, 

 should be referred to h'anica. 



The name megcerina seems only tenable for the form of 

 lyssa with a yellower underside to the hindwiug. The 

 " differences'' given by Herrich-Schaffer for separating it 

 are characteristics which apply equally to any form of 

 meg (Bra.

As there seems to be some confusion as to whether 

 enervata is a seasonal form or a geographical race of
