    • n aspidiotus A very important genus of diaspine scale-insects, comprising many notorious pests of fruit-trees. The scales are small and round, those of the males being somewhat oblong; the pellicles of the female are completely superposed, and in both sexes are more or less centrally located; the pellicles are surrounded by a broad secretionary supplement; and the circumgenital glands occur in not more than five groups. To this genus belong the San José scale (A. perniciosus), the grape-scale (A. uvæ), the walnut-scale (A. juglans-regiæ), the oleander-scale (A. nerii), the quince-scale (A. cydoniæ), and many other destructive species.
