in shape, and often distinctly striate ; the two median subequal, the 

 third smaller; lateral teeth wanting or represented by the broad plates 

 laterad of the third lobe; incisions shallow, scarcely falling below the 

 edge of the segment ; paraphyses indistinct or wanting ; interlobular 

 plates narrow, two-forked at tip — two median, two in first lateral and 

 three in second lateral incision; two obliquely truncated broad plates 

 laterad of third lobe, with rudimentary third plate; spines minute and 

 inconspicuous ; anal opening narrow, oval, a little more than one-third 

 from tip; vaginal opening very broad, more than one-third width of 

 segment; dorsal pores numerous in radiating rows from tip, but smaller 

 and less abundant than in celastri; basal thickenings a narrow line 

 in four sections ; ventral thickening not marked. 



Type. — Bvtreau of Entomology No. 7693. Food plant 

 Mesembryanthcmum cdnle. Collected in Cape Town, South 

 Africa, June 29, 1897, by C. P. Lounsbury. 



Note. — This species, while resembling" very closely articu- 

 latus and the South African variety of this species, celastri, 

 differs in important characters, notably in the absence of the 

 prominent lateral spine on the pygidium, in having three pairs 

 of lobes instead of two, and in the presence of fewer and 

 smaller plates, in the absence of paragenitals, and in more equal 

 division of the body into two sections by the cephalothoracic 

 suture. The curious lateral spine or spur on the cephalothorax 

 near the suture is even more prominently developed in this 

 species than in articulatus. Nevertheless the resemblance of 

 this species as a whole to articulatus is striking. 



PSEUDAONIDIA GREENI, n. sp. 



Female scale. — Scale of adult female flat, long-oval, 3 to 3.5 mm. 

 by 2 mm. (largest specimens) ; color opaque yellowish brown. Ventral 

 scale distinctly present. 



Male scale. — Similar in structure to that of female but much smaller. 



Adult female. — Form elongate, in the larger specimens exceeding 2 

 mm., tapering regularly to tip. Segmentation distinctly marked, 

 especially behind cephalothorax. 



Anal plate. — Elongate; the lattice patch a slightly chitinized area 

 not reticulated; four pairs of similar lobes, median projecting, laterals 

 decreasing regularly in size; lateral teeth in three areas, the third or 

 basal area probably belonging to the penultimate segment ; incisions 

 shallow; paraphyses mere chitinous thickenings of bases of incisions; 

 plates narrow, three-branched at tip-^two in median incision, lateral in- 

 cisions with respectively 2, 3, and 4 plates; spines normal, anal opening 

 one-third length of segment from tip; paragenitals wanting; parastig- 

 matic pores 7 to 8; dorsal pores large and conspicuous, radiating in 

 regular rows from tip and margin ; basal thickenings wanting or incon- 

 spicuous, the ventral thickenings also wanting.
