Velar frill comparatively broad anteriorly and ventrally, narrowing considerably in posteradorsal and anterodorsal direction, and reaching the cardinal corners as a narrow flange or ridge; the decrease in width of the frill is as a rule stronger towards the posterior than towards the anterior cardinal corner. Frill of the tecnomorphs concave ventrally and posteroventrally and faintly convex anteroventrally; heteromorphs with a convex dolon anteroventrally and ventrally.
