Wings yellowish hyaline ; costa dull orange, a smoky bar 

 extending below its outer two thirds to the tip. 

 Described from two specimens. 

 Allied to P. interruptus , Klug. 



Pterygophorus uniformis, sp. n. 



Exp. al. 17-20 millim. ; long. corp. 8-10 millim. 



Both sexes with the head and thorax chalybeous green, 

 shining; abdomen with the middle segments (generally four, 

 sometimes fewer in male) luteous, edged before and behind 

 with violet-blue, the rest of the abdomen blue-black ; antennae 

 black, with very long pectinations in the male, and strongly 

 dentated in the female ; legs testaceous ; coxa?, trochanters, 

 femora nearly to the tip, and often the tips of the tibia? and the 

 greater part of the tarsi, except the basal joint, blue-black. 



Wings purplish hyaline ; a black dot near the base of 

 the second submarginal cell. 



Described from seven specimens. 



A small species, varying little, and with sexes alike. It is 

 allied to P. analis, Costa, and to a species from Victoria 

 wanting the black dot, and with a lighter yellow band on the 

 abdomen, which is too much damaged to be worth describing.
