C . viktoriaa is distinguishable from C. rostrellum by the absence of multilocular pores and oral collar ducts at anterior legs and by the presence of a large divided circulus, by the smaller number of multilocular pores, etc. The C. viktorina is also near to C. snellegi McKenzie, 1967, but differs by having 3 oral rim ducts on sternites, by the presence of C 17 , by the greates number of oral collar ducts (8) at anterior legs, by the geographical distribution and by biological features. The new species differs from all species of the related Atrococcus genus by the presence of a large circulus and by the absence of a group of multilocular pores and oral collar ducts at the anterior leg, by the number of cerarii, etc. The first instar larvae have 6-segmented antennae and C^g. No circuli. The second instar larvae have 7-segmented antennae, circulus and Cjg. Both instars have only 3-locular pores, while the tubular ducts are absent. The species C. viktorina sp.n. is named in honour of Mrs. RADICS, her maiden's name Anna VIKTORIN, who provided much assistance in the preparation of scale-insects. The C. viktor ina sp.n. was subsequently collected by the same author also at the village Perbál (Hungary) in the leaf-sheaths of Chrysopogon gryllus, on August 15th, 1982. Family: DIASPIDIDAE VINIS (1981) described a new species named A. hungaricus , from the genus Acanthomytilus Borchsenius, 1947. This genus was established for the species from gramineous plants. Later another species from woody plants was added to the genus by BALACHOWSKY (1954) and later again some more species. It was recognized by BORCHSENIUS (1966). So the genus Acanthomy tilus p resently includes 12 species and a further one will be described separately (KOZÁR and MATILE-FERRERO, 1983, in print). Of these, 3 species live on woody plants and the rest (9) on gramineous species, therefore, they form two natural groups both by their morphology and biology. The species living on woody plants have cone-like tubular ducts at the posterior spiracles between tubular ducts, too, and the Lj are situated near each other. However, the Hungarian A. hungaricus differs from both by the absence of L 2 . Because of the heterogenous character of this genus it seems necessary to separate this species at least from the rest of the genus and to erect a new genus for it. Subfamily: Diaspidinae Tribe: Lepidosaphidini Shimer, 1868 Subtribe: Lepidosaphidina Shimer, 1868 Genus: Ferreroaspis gen.n. Type species: Acanthomytilus hungaricus Vinis, 1981 General view: The mature female with a shell-like scale, somewhat distending towards abdomen, with two larval skins. Scale 0.5-1.0 mm long, 0.2-0.3 mm wide. Live female 0.450.75 mm long, lilac in colour, piriform. Microscopic view: The broadest part of the body is the second segment of abdomen. Pygidium rounded, sclerotized with a pair of well-developed lobes. Outer side of Lj excised, they are situated near each other, distance between them is less than half width of lobes. The plates are acuminate, their lengths equalling that of Other plates degenerated. The formula of macroducts: 1, 2, 2. Dorsal ducts few in number, arranged in rows on pygidium and on last abdominal segments. Perivulvar pores form 5 groups, their formula: 2-4, 1-6, 2-5. At margin of abdominal sternites 1-4 gland spines and 1-3 microducts present, which form a group at the posterior spiracles. At the anterior spiracles 1-2 three-locular pores. Labium one-segmented, stylet loop extending to half body (VINIS, 1981). Distribution and habitat: Known only from Hungary. Collected only from bark of Acer campestre. Only one generation yearly, females overwinter. The genus has been named in honour of Dr. D. MATILE-FERRERO (Paris, France), who has given invaluable help in the study of this genus. Affinities: The new genus is similar to Acanthomytilus by the character of sclerotization of pygidium, by a small distance between Lj, and by the presence of perivulvar pores, but differs from it by the presence of only Lj. It is also near to Nilotaspis Ferris, 1941, by the presence of only Lj, by the small body size and by the woody host-plants, but differs by the presence of
