SCALE-INSHOTS. 79 
Suspprvision IT.—LECANIDA. 
Female insects naked im all stages; form variable ; apodous 
im adult stage, or retaining the feet; viviparous or oviparous, 
with or without attached ovisac; abdominal cleft and lobes 
always present. Male pupee in some cases covered with waxy 
secretion. 
Genus: LECANIUM, Illiger. 
Females naked, flat or convex; viviparous or oviparous ; 
propagating without ovisac ; arboreal. 
Dr. Signoret (loc. cit., 1873, p. 396) divides the genus into 
six series, as follows :— 
(1.) Species flat, usually viviparous; example, L. hesperi- 
dum. 
(2.) Species ,more or less convex, clongated; example, LZ. 
persice. 
(3.) Species more or less globular, the skin tessellated ; ex- 
ample, L. aceris. 
(4.) Species more or less globular, the skin perforated with 
oval markings; example, L. hemisphericum. 
(5.) Species rugose, with dorsal keels ; example, L. olee. 
(6.) Species globular, with cleft beneath for attachment to 
twigs; example, L. emerici. 
The following are the only species reported as yet in New 
Zealand ; but the genus is so widely spread and the species are 
so numerous that doubtless many others will hereafter occur in 
this country.
