84 INSECTS NOXIOUS TO AGRICULTURE. 
Suspiviston III.—LECANO-COCCIDAi, Maskell. 
N.Z: Trans., Vol. XVI., 1883, p. 128: 
Female insects covering themselves with a secretion of 
cottony or felted matter, forming more or less complete sacs, 
Male insects (where known) covered with similar secretion. 
Genus: ERIOCHITON, Maskell. 
Seeretion white, felted, formed of threads issuing from 
prominent spiny spinnerets ; inconspicuous or absent on adult 
female, thicker on male pupa. Abdominal cleft and lobes 
present in all stages of female.* 
[This genus contains the insect named hitherto Ctenochiton 
spinosus. | 
51. Errocurron nisprpus, Maskell. 
N.Z. Trans., Vol. X1X., 1886, p. 47. 
(Plate XTII., Fig. 1.) 
Secretion of female white, thin, felted, formed of thin 
threads excreted from the numerous prominent spiny spimnerets, 
the threads becoming more or less matted over the dorsal 
surface. At the edge each thread corresponds to a spine, but 
has not the feathery form exhibited in the next species, L. 
spinosus, being more tubular. On the adult female the covering 
is often not to be detected, or presents only fragmentary por- 
tions ; it is best observed on the female of the second stage. 
Secretion of the male pupa white, felted, thick, covering the 
insect all over, and exhibiting at the edge a small fringe. At 
first sight the test, being obscurely segmented, presents some- 
what the appearance of a Dactylopid. Length of the felted 
mass, about 54,in. 
Larva normal, flat, elliptical, active, exhibiting the usual 
abdominal cleft and lobes. Dorsal surface covered with spines, 
excreting a thin white mass of tubes and a tubular fringe. 
* In both of the species here described the adult female has the tibies shorter 
than the tarsi. The author has hesitated to found a generic character or it 
until the discovery of other species; the character is quite exceptional in the 
family, occurring (besides) only in some species of Acanthococcide@. In all others 
& tibia shorter than the tarsus would indicate an immature insect.
