The larva of this fpecies is of a green colour varied with yellow, 

 andhas the he ad black : the pupa is pale brown. The upper furface 

 of the fly in both fexes is brown, and the lower a rich and elegant 

 iilky green. Near the centre of the anterior wings on the upper fur- 

 face is an obfcure paler fpot of an oblong form, and which is com- 

 monly moft confpicuous in the male. The two fexes may be in a 

 great meafure diftin guiflied likewife by the number and fituation of the 

 white dots on the lower furface of the pofterior wings, thefe in the fe- 

 male conftituting an uniform feries or line extending entirely acrofs, 

 while in the male they are interrupted, and though diftincT: On the 

 edges of the wing, are fcarcely perceptible towards the diilc. The fe- 

 male is alfo larger than the male ; a circumftance not peculiar to this 

 fpecies, but common to moft others of the infe6l tribe.
