ful description with Maskell's types, it is possible to state that the two 

 are very plainly congeneric, and that of the differences suggested by 

 Green,^^ only that of the number of antennae segments stands, and 

 even this can be accounted for on the basis of immaturity. The early 

 stage of the Maskell specimens would preclude the formation of a com- 

 plete test, and the anal ring actually has six setae, such as Green de- 

 scribed for E. theae, instead of eleven as figured by Maskell. As a 

 matter of opinion, the writers consider the two to be the same species. 

 The following generic diagnosis has been based upon the two 

 Maskell species from New Zealand. 



GENERIC DIAGNOSIS OF ERIOCHITON. 



Coccine forms of the Fernald Catalogue, the adult female enclosed 

 in a test composed of compact felted secretion, this test more or less 

 complete; adult female elliptical, antennae T-segmented, legs small, 

 normal, claw with denticle, mentum 1-segmented, margin and dorsum 

 of body with long, slender, blunt-tipped spines more or less numer- 

 ously developed, spiracular spines not differentiated, dorsal and ven- 

 tral surfaces with some slender setae, only small, slender, long-tubular 

 ducts and tiny quinquelocular disk pores present on body, anal phites 

 stout, broad, with a large stout, blunt dorsal spine and some setae, with 

 one large fringe seta on each side, hypopygial setae -wanting, anal ring 

 with pores and eight setae; larva stout, antennae 6-segmented, legs 

 stout, normal, claw with denticle, at least the margin of the bod}' with 

 a fringe of long, slender, blunt-tipped spines, spiracular spines not 

 differentiated, only long tubular ducts present, at margin, anal plates 

 more or less retracted, stout, with stout spines and setae, anal ring with 

 pores and six setae. 



Genus MALLOCOCCUS Maskel!. 



Plate 4, fig. 1. 



Genotype. — Mallophora sinensis Maskell. 



Reference.— FQvuiild, Cat. Cocc. World, 1903, p. 142. 



Mallococcus is a new name substituted by Maskell for the genus 

 name MaUofhora., established by him for the single species siiiensis, a 

 name which proved "to be preoccupied. 



There are four slides of the type of this genus in the Maskell collec- 

 tion, one of " adult female, 1896," one of " abdomen of female, 1896,'' 

 one of " antenna of female, 1896," and one of " larva, 1896." There is 

 in addition a little unmounted material under No. 512. 



Adult female. — "Covered by a closel}'-- felted secretion" — (Mas- 

 kell), this, in the dried material a dense but brittle, almost homo- 

 geneous test ; bod}^ stout, elliptical, almost circular, shriveling into a
