Wings vitreous; veins green. Fore wings covered with minute 
tubercles; apical third part with very numerous and mostly irre- 
gular veinlets. Hind wings with very few veinlets. Length of the 
body 3} lines; of the wings 7 lines. 
This species, as regards the veins of the fore wings, differs 
much from most of the other species of Dictyophora, and approaches 
the genus Plegmatoptera,
