4. Aeolochroma venia sp. nov. (pi. XXIV, fig. 1). 

 $ , 41 — 42 mm. 



Closely related to prasina Warr., structure and general coloration 

 and markings nearly the same. Smaller, antennal ciliation perhaps 

 slightly shorter. Abdomen beneath more ochreous, without the dark 

 anterior shading of 3 prasina. 



Fore wing (as also the body) with the green shade more vivid, more 

 yellowish ; basal patch weak, posteriorly almost obsolete ; median area 

 broader posteriorly than in prasina, anteriorly green (only costally dark- 

 spotted), posteriorly with the glaucous-whitish, dark-dusted shading 

 much more extended than in prasina ; the rufous-brown shade proxi- 

 mally to the subterminal rather strongly and uniformly developed from 

 R, 2 to hindmargin, gently incurved. Hind wing slightly rounder than 

 in prasina, less produced tornally ; as far as the postmedian line pre- 

 dominantly flesh colour, with some glaucous-whitish admixture, distally 

 a little more variegated than in prasina. 



Both wings beneath as far as the postmedian line without the dark 

 suffusions of prasina, the hindmargin predominantly whitish, the rest 

 of a rather uniform orange, except for small pale patch distally to the 

 cell-spot of the fore wing ; subterminal blackish shade of fore wing 

 much less extended distally than in prasina ; postmedian line of hind 

 wing straight or almost straight.
