Hort. Soc., vol. xxvi, p. 746, fig. 314 (1902) ; 

 Coccidse Brit. Isles, vol. i, p. 63. 

 Rhizdecus (?) terrestris (Newst.), Cockerell ; Proc. 

 Acad. Nat. Sciences Philadelphia, 1899, p. 265. 



Adult female (figs. 2-4) greenish-yellow, but so 

 covered with a fine mealy powder as to appear quite 

 white (fig. 4) ; anal extremity with two very short 

 waxy appendages. Form very elongate, sides parallel, 

 gradually narrowed towards the posterior extremity, 

 rounded in front; segmentation distinct. Antennas 

 (figs. 5, ba) geniculated, of five joints, of which the 

 fifth equals in length the second, third, and fourth 

 together, and possesses three or four (usually three) 

 long, curved, or falciform, blunt spines ; all the joints 

 have fine hairs. Legs (fig. 6) strong, with many fine 

 hairs ; tarsi and claws without knobbed hairs ; all the 

 coxse are supported by a strong epimeron (fig. 6 a). 

 Men turn biarticulate, and very long ; apical joint 

 longest ; filaments (fig. 2) rather stout, loop reaching 

 midway between the intermediate and posterior legs. 

 Anal lobes pronounced, owing in a great measure to 

 the position of the anal orifice, which is much recessed ; 

 they are furnished with long hairs. Dorsal dermis 

 thickly set with fine hairs, which are much the longest 

 at the margins ; there are also equidistant groups 

 of usually three simple spinnerets along the margin, 

 and there is a similar series along the dorsum. On 

 the cephalic region of the dorsum, immediately over 

 the base of the mentum, are two large eye-shaped 

 glands ; and there are two others of the same character 

 towards the anal extremity. Ventral dermis with 

 fewer and finer hairs. 



Long, 1-2-25 mm. ; wide, '50-1 mm. 



Young adult female much smaller than the adult, 

 but differing in none of its structural details, except 

 that the anal lobes are slightly more pronounced. 



Long, -50-1 mm. 



Ova (fig. 7) translucent, white, and farinose, laid
