Habitat. Cheltenham, Pa. 



Described from twenty-five specimens kindly sent to me by 

 Prof. H. A: Surface, the economic zoologist of Pennsylvania. 



Scsia rhododendri is closely allied to Scsia pyri and Sesia 

 scitula, but may be distinguished at once from these species by 

 the absence of the yellow marking on the thorax. In rhodo- 

 dendri, the thorax is wholly metallic blue black above, while 

 in scitula and pyri the thorax is distinctly marked with yellow 

 along the patagia and at the posterior end. The larva of rhodo- 

 dendri infests the branches of Rhododendron. The types are 

 with Prof. Surface and in the American Museum of Natural 

 History.
