﻿NOTES AND OBSERVATIONS. 241 



" Colour : Cerri, darker, greyish brown. 

 ^Esculi, lighter brownish grey. 

 " Marginal peacock eyes, hind wings : — 



Cerri, diminisbing rapidly in size as they extend from the 



anal angle ; and somewhat lighter ground-colour. 

 jEsculi, not diminishing in size from the anal angle out- 

 wards ; somewhat darker than ground-colour. 

 " Kow of spots or white lines, hind wings : — 



Cen-i, extending from anal peacock-eye to nearly middle of 



costal edge. 

 Miiculi, nearly parallel with hind margin. 

 " The arrangement of these spots or dashes to one another 

 is quite different in these two species. There is, also, a 

 difference in the shape of the tails." 



This latter point Mr. Tylecote emphasises in his communica- 

 tion to Dr. Eosa as follows : — 



" (i) Cerri : Tails generally thin, and of the same breadth 



throughout ; tips of antennae dark brown. 

 " (ii) Msculi: Tails short, and wedge-shaped; tips of antennae 



dark brown." 

 I have again examined the examples of both species in my 

 possession, and recognise Dr. Eosa's additional points of 

 differentiation now brought to notice. Guen6e, as recorded, 

 remarks a difference observable between the respective antennae ; 

 but his label in the Oberthiir collection does not specify of what 

 these differences actually consist.
