. Contributions from the Department of Zoology and Entomology. Zoology; Entomology; Insects. 16 —. Fig. 16. Seincophanes ocellatus. Dorsal views macropterous female at left, micropterous female in middle. Male at right. Below, ventral views of female abdomen macrop- terous at left, micropterous at right. Male extreme right. globular portion of abdomen; wings wanting or very rudimentary; abdo- men at base slender; joints three to eight forming a sub-globular, slightly flattened broad portion; a prominent pleural fold extending from the base to end of seventh segment. Color: Head, thorax, elytra, base of abdomen, the second joint of antennce, femora, tibia? and base of tarsi reddish brown; first joint of antennae yellow; a bright yellow spot on elytra as in macropterous forms, apex of second joint and all of third and fourth, and tips of tarsi fuscous. Abdominal 4-7 segments black or pitchy brown entirely, beneath in two triangles, the apices of which nearly meet in the median line. No brachypterous male has been observed. Macropterous form.—Female: Similar to brachypterous form but with fully developed elytra and wings, a much less extended abdomen, and the pronotum widened at base with prominent angles. Length, , to tip of elytra, 3 mm. Head smaller and with front less convex than in brachypterous form; antennae similar; prothorax much less tumid, narrower in front and widen- ing posteriorly to form prominent humeral angles, and with the posterior margin overlapping scutellum and base of elytra; scutellum similar or a trifle larger; elytra broader and shorter than in males; the tip of corium not projecting as an obtuse angle; wings reaching to tip of elytra; abdomen slender at base, expanding to end of seventh segment, where they are almost as wide as the folded elytra, then contracting sharply to tip, flat- tened, the tip of ovipositor Please note that these images are extracted from scanned page images that may have been digitally enhanced for
