setae; larva oval, antennae 5-segmented, terminal annulate, legs 

 slender, normal, margin of body with a few ducts and setae, pygi- 

 dium somewhat developed, anal ring near apex, median lobes only 

 developed, separated by a rectangular projection bearing setae, apical 

 setae long, no traces of plates, but with incisions and marginal ducts 

 and setae. 



This genus was placed as a synonym of Aspidiotus in the Fernald 

 catalogue, and its identity with Targionia has been suggested. As 

 already noted, the type species seems, except for the question of the 

 size and the position of the anal opening and the fused median lobes, 

 to resemble A. camelliae Signoret {rapax Comstock) quite closely. 

 The writers prefer not to comment on the question of the zoological 

 validity of this genus at present. 



Genus AONIDIELLA Berlese and Leonardi. 



Genotype. — Aspidiotus aurantii Maskell. 



Beference.—FeTiiiild, Cat. Cocc. World, 1903, pp. 285, 287-8. 



This genus was established for the single type species. The 

 Maskell collection contains two slides marked as collected in 1877, 

 and therefore presumably the type slides. This species has been 

 shown to be extremely widespread and common, and has been de- 

 scribed and illustrated with elaborate detail by Berlese,^^ because of 

 which no attempt is made here to redescribe or figure it. The 

 writers are not able to comment definitely on its generic validity, 

 and have in consequence done nothing more than record its right to 

 a place in the series of genera discussed in this paper. 



The four following units have been variously designated by 

 Leonardi, who described them, as genera or subgenera of the genus 

 Lepidosaphes {Mytilaspis) . While their standing is in most cases 

 uncertain, they have been placed as genera in this paper. 



Genus PHAULOMYTILUS Leonardi. 



Plate 5, fig. 5. 



Genotype. — Mytilaspis striata Maskell. 



/fe/erence5.— Fernald, Cat. Cocc. World, 1903, pp. 304, 314.— 

 Leonardi, Ann. E. Sc. sup. agr. Portici, ser. 2, vol. 5, 1904, p. 5. 



This genus has never included more than the single type species. 



The Maskell collection contains a single slide of "adult female, 

 1894" and a small quantity of unmounted material of this species, 

 the latter bearing the No. 409. 



Adult female. — Scale as described by Maskell and Leonardi ; body 

 elongate, broadest behind the middle, sides of cephalothorax tapering 

 strongly anteriorly, this apex rounded; cephalothorax in fully ma-
