LEPIDOPTERA HETEROCERA. 13 



Fore wings subfalcate, with a short line in front between the two 

 entire lines ; a few slender fawn-coloured streaks, which are mostly 

 between the exterior line and the exterior border ; costa with little 

 transverse black lines. Hind wings with short tails, which are 

 adorned at the base with a deep black red-marked spot and with a 

 red black-marked spot, which is bordered by contiguous black 

 streaks; second line composed of oblique contiguous brown streaks ; 

 some transverse brown streaks along the apical part of the interior 

 border as far as the interior line. Length of the body 9 lines ; of 

 the wings 22 lines. 



This species and U. Podaliriata differ widely from each other 

 in the caudal part of the hind wings, but they nearly agree in 

 all the other characters.
