Extract

Alate Viviparous Female: Body, legs, antennae, and cornicles bearing moderately long setae, but not conspicuously hairy. In cleared specimens, the following parts are dusky brown: head, thorax, cornicles, cauda, coxae, rostrum and bases of the femora; a very short basal portion, and the distal half of the tibiae; tarsi; antennal joints I, II, VI, and distal portions of III, IV and V. As in many other species in this genus, there are four longitudinal rows of small brown spots dorsally on the abdomen, extending from the thorax to the area between the cornicles, and two rows laterally, one on each side, composed of somewhat larger brown areas around the spiracles. Remainder of body and appendages clear. Wings hyaline, with media faint and twice-branched. Antennal sensoria, III 5(4-6); IV(1-2); V 2. Ocular tubercles present.
