into iiccouiit. Ill Mr. Tiitt's tabulation no coiriiisaiice is taken of tlie variability 

 of tbe liindwiug, wbich is as important as that of the forewing, considering that 

 filirn' and c//ri,^foj)/i/ differ especially in the hindwing. An ab. jjaUida-transvrrsii 

 with dark hindwings is not the same as one with pale hindwiugs ; so we should 

 have ab. jjal/ida-tm/isversa-somethmg ; and this, combined with the variation 

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

 reader will dunbtless perceive that we liave here to do with a confusion of ideas, a 

 name being replaced by a kind of diagnosis, while, in fact, the diagnosis should be 

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

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

 submarginal shade of the hindwing ; the spurs are, moreover, somewhat shorter 

 and the tenth abdominal tergite and sternite are rather slenderer.
