. Bulletin. Science; Natural history; Natural history. 1971 ORIENTAL ' 71 anteriorly, eyes essentially Hush with general surface. Labrum prominent, broad and weakly pointed, ratio of length-to-width 16:22 (73%), Head ratios are: (I) Total median length-to-widlh (including eyes) 65: 78 (83%) across hyperocheal angles, (excluding eyes) 65: 55 (85%) anteriorly; (2) anterior distance between eyes to posterior distance between eyes 55:40 (73%); and (3) antei km distance between eyes to inner eye length 55: 40 (73%). Pronotum: Yellow, with two diffuse brown areas centrally, surface shiny but weakly roughened. Posterior border double-angulate, the outer angle- being the usual posterolateral one, the inner angle being a moderate, caudally-directed angulosity of the border; neither angle long or sharp. Lateral border smoothly curved; percent of curvature (as viewed perpendicularly to the frontal plane of section of the specimen as a whole) about 15 (68: 10). Venter yellow, coxal cavities large, median area moderately keeled. Internal propleural flaps widely separated by coxal cavities. Ratios are: (1) Width between anterior angles to width between posteroexternal angles 43:92 (47%); (2) width between anterior angles to width between postero- internal angles 43: 73 (59%); (3) median length to greatest width 25: 92 (27%); and (4) median length to parallel length from anterior angle to posterior border 25: 39 (64%). Winged form with straighter lateral borders, angles closer together, less pronounced, appearing more as the two edges of a longer, single angle which had been cut across diagonally, thus pro- ducing two reduced angles. Pronotum longer, broader, the proportions being: (1) Width between anterior angles to width between posteroexternal angles ( = widest part of pronotum) 43: 87 (49%); (2) width between anterior angles to width between posterointernal angles 43:78 (35%); (3) median lengthtogreatestwidth27: 87(31 %);and(4)median length to parallel length from
