CALOPHYA TRIOZOMIMA CLARIPENNIS, new variety. 



This varietal form is very similar structurally to the species, but 

 differs in the following respects. The vertex is more flattened and 

 the front oceUus more nearly visible from above. The color differ- 

 ences are marked. The body is uniformly honey-yellow throughout; 

 the forewing laclis the dark macula in the basal cell present in the 

 species. The genital characters are quite similar.
