SUBFAM. ECTOBIN/E 



Characters. — Antenna 1 setaceous or plumose. Tegmina of horn} - texture or coriaceous, fully 

 developed, scale-like or absent. Wings, when present, with prominent triangular apical field or with a 

 large reflected and folded apical area, the ulnar vein simple or bifurcate except in the genus 

 Anaplectoidea where it is ramose. Legs slender, femora usually sparsely armed beneath. Supra-anal 

 lamina of both sexes various in shape but typically narrow and transverse. Ootheca with a longitudinal 

 crest and before deposition carried with the crest uppermost and the eggs disposed vertically (1),
