 Hab. Kaisaa; Bachian. 



This species closely resembles P. elegans from Key Island, from which 

 it differs in being much less decorated with yellow markings on the head 

 and thorax, but has an additional fascia on the abdomen ; it may, however, 

 be an extreme variety.

 hyalinis, nervis ferrugineis. 



Female. Length 6 lines. Head black ; the cheeks, the outer orbit of 

 the eyes, two oblique spots on the vertex behind the ocelli, a line on 

 the inner orbit of the eyes, terminating in their emargination ; the 

 mandibles, clypeus, antennse, and a transverse line above their inser- 

 tion, ferruginous. Thorax : the prothorax, an oblong spot on the 

 mesothorax, the scutellum, femora, tibiae, and tarsi, ferruginous ; the 

 posterior margin of the prothorax narrowly, the postscutellum, and 

 two longitudinal stripes on the metathorax, yellow ; the wings hya- 

 line ; the nervures ferruginous. Abdomen : the first segment black, 

 with the apical margin yellow ; the second ferruginous, the base
