Extract

aspidiotus cueroensis, n. sp..—♀. Scale diam, slightly over 1 millim., circular, slightly convex above and beneath, with the margin somewhat elevated, like an oyster; very pale gray or grayish- white, quite a delicate shade, exuviae more or less to one side, covered, inconspicuous, but appearing as a dark spot on the inside of the scale. ♀. Shape ordinary; black when dry. No circumgenital glands. Anal orifice elongate oval, moderately large, distinct from bases of lobes about 1½ times its length. Only one pair of lobes, these and the area about their base remaining dark brown after boiling; lobes rather large, but short and broad, contiguous at the base, but thence diverging to their rounded apices, whence they slope downwards to the comparatively short outer side, the shape of the lobes being almost as in A. ostreaeformis.
