EUCHROMIA HuBNER. 



Wings more or less narrow and elongated, opaque or marked 

 with a few hyaline or limpid spots. The wing structure and out- 

 line of the fore wings are more markedly sphingiform than in the 

 genus Glaucopis. The subcostal vein gives rise to two marginal 

 branches from the hinder part of the disk to the post-apical branch 

 midway between the origin of the subcosto-inferior branch and the 

 tip of the wing ; the subcosto-inferior and discal vein arise from 

 the subcostal at a common point. There is no disco-central branch. 

 The median is 4-branched, with the medio-posterior remote from 

 the other branches. The submedian simple. The hind wings are 

 rather more than half as long as the fore wing ; without costal 

 nervure ; subcostal bifid from the origin of the discal, which is 

 obliquely curved towards the base of the wing and gives rise to
