Of these A8 is an exceptionally fine male in beautiful colora- 

 tion ; the black of the abdomen starts on the posterior half of 3. 

 I am in doubt of another specimen Bi which differs from the 

 remaining by its smaller size and the clearness and transparency 

 of its wings ; all the others show a decided tinge of yellowish 

 dulling throughout the wing; in addition the stigma of Bi is 

 shorter. The form of appendages and other characters, however, 

 lead me to place it with T. stella. 



Besides the characters shown in the table Mr. Williamson 

 adds the following notes from his material : 



Antenodals : fore wings 6 in 4 wings, 7 in 22 wings ; hind 

 wings 4 in 23 wings, 5 in 3 wings, 7 in 3 wings. 



Postnodals : fore wings 5 in 9 wings, 6 in 12 wings, 7 in 7 

 wings, 8 in hind wings, 5 in 4 wings, 6 in 1 wing. 



Cubital vein : coincident with A4 in 6 wings of the males, 

 distal in 12 wings. 



Substigmal series arising: fore wings, between 3-4: 10 wings; 

 at 4 : 6 wings ; between 4-5 : 8 wings ; opposite 5 : I wing. 

 Hind wings, between 3—4: 15 wings; opposite 4: 4 wings; 

 between 4-5 : 7 wings ; opposite 5 : 1 wing. 



Triangle fore wing free : 2 wings ; crossed : 24 wings.
