into account. Ill Mr. Tutt's tiilmlatioii no cognisance is taken of the variability 

 of the liindwiug, which is as important as that of the forewing, consielerii."- tliat 

 fdiae and vhvhtophi differ especially in the hindwing. An ab. palliJa-transvn-sa 

 with dark hindwings is not the same as one with jiale liindwings ; so we should 

 liave ab. palUda-trnMsc,'rsa-somQ{\\mg ; and this, combined with the variation 

 111 tlie venation, for instance, would give a four-barrelled name, and so on. The 

 reader will doubtless perceive that we have here to do with a confusion of ideas, a 

 name being rejilaced by a kind of diagnosis, while, in tact, the diagnosis sliould be 

 replaced by a name.— Tenth segment see PI. XXIV. f 22 and Pi. XXVI. f 37.

S ? . This is nothing else but a rej.reseutative form of tiliae, difiering in the 

 darker colour, which is never green, and in tlie more distal position of the dark 

 snbmargiual shade of the hindwing ; the spurs are, moreover, somewiiat shorter 

 and the tenth abdominal tergite and sternite are rather slenderer.
