milar fashion as they were rolled up in the embryonic stage (Fig. 3). Now the insect moults, leaving the skin behind to which the skin of the trunk is now attached (Fig. 4). When it is ready to take up food again, the new trunk is formed from the roll through the labium. At each moulting the insect loses its wax prolongations, which are secreted anew afterwards. The first larva possesses only two prolongations, the fully grown female has 34, a number characteristic for the species. The prolongations develop on the cerasii, on the coniform pores of which (2-4 on each cerarium) long, transparent needles are formed, and the latter is enveloped in a cotton-like wax formation secreted from the disciform pores. The shape of the needles is of taxonomic value (Fig. 2). Irodalom 1. BEARDSLEY, J. (1965;. Notes on the pineapple mealybug complex with descriptions of two new species (Homoptera, Pseudococcidae)
