In lateral view both mandibles similar (more or less gradually tapering to apex). Vein2r-m normally present in both fore wings. Supraclypeal areadensely setose. Antennashort to long: ♀shorter than length of fore wing costa, to as long as combined length of fore wing costa and pterostigma; ♂shorter than costa to longer than combined length of costa and pterostigma. Cercus moderately long: about 3.5–6.0× as long as maximal width, and in dorsal view reaching back at least to middle of valvula 3. Medial and basal annuli with flat ventral edge (serrulae not clearly developed). Penis valve ventrally with small spines; base of valvispina ventrally clearly divided from lobe on which it arises by an incision or at least a right-angled turn. Larva. Third abdominal segment with 3 or 4 dorsal annulets. Suranal plate with minute pseudocerci placed very close together. Gall. In leaves. Always attached to midrib: very rarely, a female may oviposit by mistake into lateral veins ( Fig. 327), but larvae in such galls fail to reach maturity. Spherical, or bladder-shaped, or irregularly pyriform. Developed only below the leaf-blade, or projecting on both sides. Phenology. Most species strictly univoltine, but  E. vesicatorand  E. viminalisbivoltine, where climate allows. 1657189039 Costa 85 86 1 Costa 1657189057 Antenna Vein Supraclypeal area 85 86 2 1 1
