This genus was created by Targioni-Tozzetti for the reception of a coccid, 

 which Dufour has described under the name of Aspidiotus luzulce. Cockerell 

 has created a new genus [Luzulaspis) for this insect. I follow Newstead, 

 who has retained the second name. 



Newstead says : " Adult female narrowly elongate ; antennae eight-jointed, 

 and legs well developed. Anal ring with six hairs. Ovisac of female very 

 elongate, sometimes clavate, closely felted, and open at the narrow anterior 

 extremity. Male with short styliform genital armature. No caudal fila- 

 ments. Male puparium glassy, elongate, with the ends rounded and rather 

 deep; perpendicular sides, which give it a somewhat box-shaped form."

The typical form of this genus was originally described from France and 

 England upon several species of rushes, belonging to the genus Luzula. 



In 1892, Maskell determined specimens, probably introduced from Europe, 

 upon grass collected at Nevertire, New South Wales. In the following year 

 he suggested, chiefly on account of its greater size, that it might be defined 

 as var. australis. Fuller recorded the identification of this species upon a 

 sedge in Western Australia in 1899. 



Adult female yellowish brown, enclosed in a narrow elongated convex sac, 

 composed of closely felted white cotton. Antennae eight-jointed, third and 

 fourth longest. The margin of the body bears some small spines, and the 

 epidermis covered with tubular spinnerets. 



Newstead's description hardly agrees with Maskell's, for he says, " Ovisac 

 composed of closely felted white wax." I have never seen this species.
