 more evenly rounded, that is, the outer margin is not as straight as 

 it is in the others. 



Cacama californica new species. 



Type male and allotype female from Los Angeles County, California, July 

 (Collection Coquillett). U. S. Xational Museum. 



This species resembles Cacama variegata in color pattern and general 

 appearance, and the rostrum is of the same length, but it differs otherwise in 

 the following particulars : The head is usually smaller ; the fore wings are 

 narrower with the outer margins more straight, and with the space between 

 the marginal cells and the edge of the wings very broad. The basal cell is 

 nearly clear, and the first and second cross veins are hardly infuscated. A 

 side view of the abdomen shows the operculum to be sinuated on the margin, 

 instead of evenly curved as in variegata. The opercula are also shorter though

 above or below is seen to be broader or more flattened out.
