 Expanse : 28 mm. 



Habitat. — Colorado . 



Type : One female. Coll. Dr. W. Barnes, Decatur, Illinois. 



Allied to Sanninoidea exitiosa and S. opalescens. What I regard as the male 

 of grczft, differs in having the bands on the abdomen and markings very distinctly 

 golden yellow. The female differs in having the apices of the fore wings more 

 rounded than in either exitiosa or opalescens, and has a somewhat transparent 

 area, with indications of a rather broad transverse mark. The abdomen is either 

 wholly green or blue black or has the fourth segment wholly orange above or only 

 partly so. In the larval stage the insect lives in the main roots of wild cherry., 

 The moth emerges in July and August.
